Optimize with keywords

Expand Your Keyword List

Once you have completed your brainstorming and have compiled your list of 5-10 core keywords, its time to move on and expand that list. A list of 5-10 search phrases will generally not bring the amount of search engine traffic needed to make your website successful. However, that list will be a vital tool when determining which phrases to add to the mix.
At this point, you need to turn to the search engines themselves and research which search phrases are actually being typed into Google, Yahoo, MSN et al. While few search engines will openly tell you which search phrases are the most often searched, there are a couple of very useful tools you can use to expand your list.
The first and most well known, is the Overture Search Term Suggestion Tool. This great little research tool is primarily for the use of Overture PPC users. Take any of your main search phrases and enter them into the suggestion tool. Overture will then spit out all other popular search terms that contain that phrase. In addition, Overture will place the search phrases in order of popularity and give you an idea of the number of searches per month for each phrase across their network.
While this tool can be very useful, especially as it is free to use, it does have some key drawbacks. First, it does not differentiate between singular and plural search phrases. Consequently, "desktop computer" and "desktop computers" are combined together, leaving you to use your own judgment as to which variation is the most popular.

 
Just like any type of text-based content, video SEO involves optimizing with target relevant keywords — both for search engines and for user experience. Use keywords in: File name Title Tags URL Link text Beyond that, include a paragraph of optimized text that provides a brief description of the video. Again, the benefits are twofold: You’ll improve the user experience and your search rankings.

Video SEO optimization in 2013

 To Better Video SEO

YouTube released plans Thursday that allow channel producers to sell paid video subscriptions that will create a new marketplace for programming on the Internet, making it crystal clear why the company continues to build out an Internet-connected fiber network at 1-gigabit-per-second speeds. By 2020, that content could serve up on many of the 30 billion wirelessly

Aside from the subscription service, marketers should prepare to see a variety of ads that embed video clips, such as a hybrid paid-search ad on Google and Bing shopping-like sites to help boost ecommerce. Q1 2013 ecommerce sales grew 13% year-over-year to $50.2 billion, according to comScore numbers released Friday.
While Google research shows that shoppers using mobile devices tend to spend more in stores, video platforms like Joyus, the video shopping platform startup led by former Google exec Sukhinder Singh Cassidy, will become a catalyst for ecommerce built through video. Investment firms like InterWest Partners and Time Warner Investments think so, too. The companies recently contributed to an $11.5 million second funding round in Joyus.
Video has already been popping up in retail sites like Saks Fifth Avenue to demonstrate runway looks. Knowing how to optimize that content for search engines will become critical.
Universal search for categories from retail to travel serves more video clips in query results. Search on engines often times remain the starting point for in-store mobile consumers. Some marketers assume smartphone shoppers use shopping apps or navigate directly to brand and retail Web sites while in a store, but Google found that 82% of smartphone shoppers use mobile search to help make purchase decisions.
Dave Witting, VP of global customer success at Brightcove, provides seven quick SEO tips for marketers looking to optimize video aimed at driving more traffic to brand sites.

Thumbnail quality is important The editorial quality of your thumbnail trumps image quality. Put another way, choosing compelling thumbnails for your content can increase user clicks. Higher user engagement will impact your SEO results. It's also worth noting that an image thumbnail will always get better traffic results than a generic video icon or a "click here for video" text link.

Ensure that the site is optimized The most flawless video SEO is worthless if your site is not optimized. It's always a good best practice to ensure your Web site's SEO is optimized before tweaking your video settings.

 Lot of companies and websites are just starting to recognize their potential in being distributed.  Sometimes people just do not feel like studying an article.  NetConsultCo.com describes why a lot of press information websites now couple their online articles with an included movie.  Also, when scrolling through a social social networking site, most audiences are more willing to watch videos clip based rather than reading large articles.

Last but not the least i recommend you to follow the basics of seo and you will do wonder don’t waste your time in black hat techniques that can penalize your Blog and one phrase which  i use for Google is “Love Google will love you back”

Social Media Strategy-seo-tips

What is important to understand your social media goals and objectives and how they tie into your overall company goals. Remember this thing likeKeep it specific, measurable, Attainable, Realistic/Relevant, and Timely.

Let’s take some commonly used objectives:

Improve the brand presence across social channels: Here, The goal is an increase the number of followers comes on Twitter, number of fans on Facebook, subscribers, number of comments, number of times your brand is mentioned in blogs and forums and so on.

Increase the positive sentiment about your brand: The goal here is to convert the number of positive mentions while taking note of negative mentions.  Has the ratio of positive to negative comments improved through this strategy?  With the good comes the bad in social media.

Develop the relationships for future partnership opportunities: This goal is to keep track of those with whom you have connected.  For example, if you met a potential speaker for your webinar, include that person into your digital Rolodex.  If a person contacts you through your blog, capture that lead and take note.

Increase the traffic on your website: To Keep track of visitors to your website who come from each of your social media sites.  If you are promoting an event using social media, consider using a unique code to track the campaign.

In general terms, I view social media as a strategy, not a tactic. As per my views, I consider that the social media platforms like blogs, Twitter, Facebook, digg, stumbleupon, jumptage etc., as tactics that tie into the social media strategy.  In other words, outline your social media strategy and support your strategy with tactics.

In what ways did you implement what you learned on your own blog?

I quickly realised that Adsense was not a strategy for me moving
forward. There were far better ways to monetize my blog. That is
why I started working on my own product: an eBook with 30 London
Cycling Routes). The eBook has been a huge success and I wouldn't
have thought to create it without the course. I've had interest
from people wanting to publish it and it continues to bring in a
steady income that pays my rent.

I also started an Aweber newsletter. This helped me connect with my
audience and have their permission to keep in contact regularly. As
of today I have over 2,000 subscribers on my list.

My traffic grew a lot (I am receiving over 70,000 visits per
month now) and I practically went from $0 to $1,000 monthly in
revenues. The money I made with the blog paid for two weeks in
Brazil enjoying Rio De Janeiro. Since then things have continued to
grow and so many opportunities have arisen, such as collaborating
on an iPhone application and interviewing the Mayor of London. I'm
sure without this strong start to my blogging career I would be in
a 9-5 job now.

Web Directories For SEO

• Is it ranking in the SERPs? - If a site ranks well in the search engines it stands a good chance to be trusted by them. Plus even if those links do not count to help boost your ranking they still can drive direct traffic. I frequently see directories like Business.com and JoeAnt ranking in the search results.
  
• Do they sell direct links? - Direct links are more likely to be taken as editorial votes of quality. Some redirected links may still count, but many of them will not.
• How frequently is their site crawled? - You need to check and see if the category pages are being cached in Google, and how frequently they are cached. If their pages are not getting cached or have not been cached for 6 months then the odds are pretty low of that link carrying much weight.
• What is the quality ratio? - Does it list anyone who pays? Or do they hold sites to some quality standards? Do they categorize sites properly? Or do they sell links to anyone in any category, even if it is the wrong one? Does each page have unique content? Are most pages empty - adding nothing but clutter to search indexes? If they do not help engines categorize the web (ie: no editorial value) then eventually the engines are not going to trust their votes.
• What is the ad ratio? - Are all the listings paid? Or will they list some useful sites without payment? Does the site look like it aims to serve end users? Or does it look like it exists just to get AdSense ads or affiliate ads indexed?
• Do they sell outbound sitewide links? - Prettymuch the equivalent of selling out - when a directory puts sitewide outbound links on their site (especially if those links are to junky sites) the odds are pretty good that the links are not going to count much.
• Is it decrepit? - Directories which have 50% of their links broken or pointing at URLs that have been purchased by spammers or domainers are not going to pack as much punch as sites which have few broken links. I recently bought a 25 page directory that has not been updated in a couple years, and it had about 400 broken links in it. Not good!
• Does it have unique content? - Is it a DMOZ clone? Are its listings manually compiled and unique from what is offered at other directories?
• Is it relevant to my site? - Many small niche directories can drive decent value due to offering decent co-citation data and having exceptionally relevant traffic streams.

Bob Mutch recently rated 40 top directories based on their age, how many edu and gov links they have and whether or not they are listed in DMOZ and Yahoo!. I would contest that WhatUSeek isn't a real directory, ISEDB is a directory of search engines and directories, and that Vlib.org should be counted as a directory, but other than those minor points this is a pretty cool study.

No	URL	EDU	GOV	Age
1	www.dmoz.org	128,000	761	1999
2	dir.yahoo.com	111,000	2,060	1995
3	www.lii.org	10,400	110	1998

19	www.uncoverthenet.com	18	2	2004
20	www.qango.com	19	1	1998

I think the inbound link profile is a good starting point for rating (when you add it to the other criteria I mentioned above), but what I think is even more interesting is how quickly they fall off in the quantity of quality links.

Link Building Activities

Link Baiting: Create compelling content for advertising and increase visitor interaction on your website. Visitors that click on this content land on your website to take a look at the irresistible offer.

Social Bookmarking: Social bookmarking of your website is a good way to get increased amount of traffic drawn to your website.

Link wheel: A link wheel is the process of creating 12 or more new blogs on a particular topic. On each of those sites, you write 200 words of unique content, and include 1 link to your targeted site and 1 link to one of your other blogs.

Reverse SEO: It is a process by which you can improve the ranking of your website and decrease the ranking of your competitor’s website. And the method used is – heavily spam the competitor’s website with a lot of irrelevant links.

Link farms: If your site has lots and lots of links linking to you and all these links are low in quality, built for the sole purpose of increasing inbound links, Google looks at these as “Link Farms”. Link Farms are deliberately created with a whole bunch of low quality links.

Matt Cutts Talks SEO for Google

The latest Google Webmaster video features Distinguished Engineer Matt Cutts talking about what webmasters can expect to see in the next few months in terms of SEO for Google, particularly changes combating black hat web spam from many different angles in a variety of areas.
Here are nine search and SEO changes webmasters will likely see – although, as always, Cutts warns nothing is set in stone and it should be taken with a grain of salt.

1. Next Generation of Penguin – Penguin 2.0

This update is to try and target more black hat web spam. The new Penguin 2.0, which is the name Google uses internally for the next gen Penguin, will be much more comprehensive than Penguin 1.0 and it will go deeper and have a larger impact than the original.

2. Advertorials

Many advertorials (a.k.a., native advertising) violate Google's quality guidelines. More importantly, they should not flow PageRank.
Google is planning to be a lot stronger on their enforcement of these types of paid links and advertising, disguised as “advertorials”. Cutts did clarify there is nothing wrong with advertorials, simply that they don't want them to be abused for PageRank and linking reasons. If you use advertorials, Cutts suggested that they should be clearly marked and obvious that it is paid advertising.

3. “Payday Loans” in .co.uk

Cutts mentioned that this is a problematic search, and there are others like it, so they are tackling it a couple of different ways. For those that play in that space, however, you're out of luck since Cutts isn't revealing exactly how they are dealing with it, just that it will be happening.
He said that they are targeting specific areas (another example he included was porn queries) that have traditionally been more spammy.

4. Devaluing Upstream Linking

Again, Cutts isn't going into details about this, but they are working on making link buying less effective and have a couple ideas for detailed link analysis to tackle this issue.

5. Hacked Sites

They want to roll out a next generation of hacked detection, as well as being able to notify webmasters better. They would like to be able to point webmasters to more specific information, such as whether they are dealing with malware or a hacked site, and to hopefully clean it up.

6. Authority

If Google's algorithms believe you or your site is an authority in a particular area, they want to make sure those sites rank a little bit higher than other sites.

7. Panda

They are looking for some additional signals for sites that are in the "gray area" or "border zone", and looking for other signals that suggest the site truly is high quality, so it will help those sites who have been previously impacted by Panda.

8. Changes to Cluster of Results From the Same Site

If you're doing deep searches in Google, and going back 5, 6 or more results pages deep, you can see the same site popping up with a cluster of results on those deep pages.
Google is looking into a change where once you have seen a cluster of results from the same site, you will be less likely to see more and more from that same site as you go deeper. Cutts mentioned this as being something that came specifically from user feedback.

9. More Information for Webmasters

Cutts said they want to be able to keep giving webmasters more specific and detailed information via webmaster tools. He mentions specifically example URLs to help webmasters diagnose problems on their site.
He believes that the changes will really make a difference with the quality of the search results, as well as impact the amount of spam that is showing up.

Bottom Line

Cutts says if you are focused on high quality content, you don't have much to worry about. But if you're dabbling in the black hat arts, you might have a busy summer.

Download file using curl in php

You would need to feed CURLOPT_URL the full URL to the file. Also if you want to download a file you might want to save it somewhere.

Working example:

$curl = curl_init();
$file = fopen("ls-lR.gz", 'w');
curl_setopt($curl, CURLOPT_URL, "ftp://ftp.sunet.se/ls-lR.gz"); #input
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_FILE, $file); #output
curl_setopt($curl, CURLOPT_USERPWD, "$_FTP[username]:$_FTP[password]");
curl_exec($curl);
curl_close($curl);
fclose($file);

I used the ftp_* functions for ftp, in place of curl, because curl 
tried to change directories, but its not allowed on this ftp server, so 
the code i used is;



$local_file = 'output.rar';
$server_file = '/somedir/1/bar/foo/somearchive.rar';
$ftp_user_name='anonymous';
$ftp_user_pass='mozilla@example.com';
$ftp_server='server.host';
// set up basic connection
$conn_id = ftp_connect($ftp_server);

// login with username and password
$login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass);

/* uncomment if you need to change directories
if (ftp_chdir($conn_id, "<directory>")) {
    echo "Current directory is now: " . ftp_pwd($conn_id) . "\n";
} else { 
    echo "Couldn't change directory\n";
}
*/

// try to download $server_file and save to $local_file
if (ftp_get($conn_id, $local_file, $server_file, FTP_BINARY)) {
    echo "Successfully written to $local_file\n";
} else {
    echo "There was a problem\n";
}

// close the connection
ftp_close($conn_id);
It works !!

PHP error: Cannot modify header information

You cannot use header() once text has been output to the browser. As your header.php include presumably outputs HTML, header() cannot be used.
You can solve this in a couple ways:

• Move the if statement above the header include (this won't work, as you've indicated in comments that header.php sets the uid session and other vital stuff).
• Call ob_start() at the top of the script to buffer the output.

You can't issue HTTP headers after you have outputted content.

unction Redirect($url) {
        flush(); // Flush the buffer
        header("Location: $url"); // Rewrite the header
        die;
    }

function Redirect($url) {
        flush(); // Flush the buffer
        ob_flush();
        header("Location: $url"); // Rewrite the header
        die;
    }





To ensure your error reporting level is the same across environments, you can set it in your application using error_reporting() and ini_set('display_errors', 1)



Also check your .php files for any whitespace before the opening tag and after the closing tag.



In addition to the points mentioned above, ensure you are not 
outputting anything before the headers are set, for example the 
following code would produce an error similar to the one you are 
receiving:



echo 'Hello, World';
header('Location: http://www.somesite.com');

PHP Curl check for file existence

a PHP program that downloads a pdf from a backend and save to a local drive.

$url = "http://wedsite/test.pdf";
$path = "C:\\test.pdf;"
downloadAndSave($url,$path);

function downloadAndSave($urlS,$pathS)
    {
        $fp = fopen($pathS, 'w');

        $ch = curl_init($urlS);

        curl_setopt($ch, CURLOPT_FILE, $fp);
        $data = curl_exec($ch);

        $httpCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
        echo $httpCode;
        //If 404 is returned, then file is not found.
        if(strcmp($httpCode,"404") == 1)
        {
            echo $httpCode;
            echo $urlS; 
        }

        fclose($fp);

    }

You can do this with a separate curl HEAD request:

curl_setopt($ch, CURLOPT_NOBODY, true);
$data = curl_exec($ch);

$httpCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);

When you actually want to download you can use set NOBODY to false.

How to create update or remove symbolic or soft link Linux

Symbolic links , Symlink or Soft link in Unix are very important concept to understand and use in various UNIX operating systems e.g. Linux , Solaris or IBM AIX. Symlinks gives you so much power and flexibility that you can maintain things quite easily.I personally feel that along with find, grep and other UNIX commands, command to create soft link and update soft link i.e. ln -s  is also must for any one working in UNIX machine. Whenever I do scripting or write any UNIX script I always write for symlinks rather than pointing to absolute path of directories in UNIX. It gives you flexibility of changing the symlink or soft link without making any change on your tried and tested scripts. I have worked on many different core Java projects which run on Linux and UNIX machine and make extensive use of UNIX symbolic links or symlinks. All my project which are on finance domain and on electronic trading systems have there server running on Linux,  Since speed is major concern in online stock or futures trading where orders has to hit the market within micro seconds Linux server is ideal choice for electronic and fix trading systems and since your server is on UNIX you have to be expert of Unix command to work efficiently and these articles are my result of those effort to learn and share new UNIX commands. In this UNIX fundamental tutorial we will see How to create soft link in UNIX, How to update soft link and Difference between Soft link and Hard link in Unix and Linux. By the way this UNIX command tutorial is  in continuation of my earlier article top networking commands in Unix  and CVS command examples ,  if you haven’t read already you may find some useful information based on my experience in Unix and Linux commands.



First difference between soft link and hard link is that  Unix Soft links are pointers to programs, files, or directories located elsewhere (just like Windows shortcuts) , while Unix Hard links are pointers to programs and files, but NOT directories.
2) Second major difference between UNIX soft link and hard link is that If the original program, file, or directory is renamed, moved, or deleted, the soft link is broken and it will show in red color if you using ls -lrt --color option. On the other hand, If the original program or file is renamed, moved, or deleted, the hard link is NOT broken
3) One not so important difference on soft link vs hard link is that,  If you type ls -F you can see which files are UNIX soft links because they end with @

4)  Another difference between soft link vs hard link is how you create them, To create a soft link called "current" that points to a file or directory called "new_package", use this: ln -s new_package latest  to remember this command always remember that name of soft link comes as last argument. On the other side to create a UNIX hard link called myhardlink.txt that points to a file called myfile.txt, use this: ln myfile.txt myhardlink.txt

5) One more significant difference on soft link and hard link on UNIX or Linux is that, soft link can point to a network mounted directory also. For creating unix soft link remember to use option "-s" with UNIX link command "ln". While, Hard links in UNIX cannot span disk drives, so you CANNOT have a hard link on /dev/hdb that refers to a program or file on /dev/hda

Difference between active and passive FTP?

Active and passive are the two modes that FTP can run in. FTP uses two channels between client and server, the command channel and the data channel, which are actually separate TCP connections. The command channel is for commands and responses, the data channel is for actually transferring files. It's a nifty way of sending commands to the server without having to wait for the current data transfer to finish.
In active mode, the client establishes the command channel (from client port X to server port 21^(b)) but the server establishes the data channel (from server port 20^(b) to client port Y, where Y has been supplied by the client).
In passive mode, the client establishes both channels. In that case, the server tells the client which port should be used for the data channel.
Passive mode is generally used in situations where the FTP server is not able to establish the data channel. One of the major reasons for this is network firewalls. While you may have a firewall rule which allows you to open up FTP channels to ftp.microsoft.com, Microsoft's servers may not have the power to open up the data channel back through your firewall.


Active mode:

• Client opens up command channel from client port 2000^(a) to server port 21^(b).
• Client sends PORT 2001^(a) to server and server acknowledges on command channel.
• Server opens up data channel from server port 20^(b) to client port 2001^(a).
• Client acknowledges on data channel.

Passive mode:

• Client opens up command channel from client port 2000^(a) to server port 21^(b).
• Client sends PASV to server on command channel.
• Server sends back (on command channel) PORT 1234^(a) after starting to listen on that port.
• Client opens up data channel from client 2001^(a) to server port 1234^(a).
• Server acknowledges on data channel.

Multiple array in php

If the ID, topic and description are all in the correct order in each comma delimited string you are supplying to the script, you could use the following to create a single array key'd by the ID: $id = explode(',',$data->id); $topic = explode(',',$data->topic); $description = explode(',',$data->description); foreach($id as $key=>$val) { $results[$val]['topic'] = $topic[$key]; $results[$val]['description'] = $description[$key]; } $newArray=array_merge($topic,$description,$third_array); foreach($newArray as $key=>$value) { echo "$key- $value <br/>"; }

SQL Injection Prevention

the value should only be a positive integer value, since it's an id number. We do sometimes use other variables that could be a letter, or a string of text, for example, the search results pages.

$variable = "0";
if (isset($HTTP_GET_VARS["id"])) {
  $variable = (get_magic_quotes_gpc()) ? $HTTP_GET_VARS["id"] : addslashes($HTTP_GET_VARS["id"]);
}

basic SEO factors

It is quite easy to learn the basic SEO factors if you spend a
couple hours researching on the web. Here is a quick summary of
them:

-You need to have unique and useful content.
-You need to have quality and relevant backlinks.
-Your title tags should be unique and contain your main keywords.
-Your permalinks should be based on keywords rather than symbols.
-Your website shouldn't have many folders, and its pages should
be interlinked.

If you follow these guidelines soon you'll start getting a decent
amount of traffic from Google.

You should be careful, however, to not become greedy and start
over-optimizing your website, which is a mistake I see many new
bloggers and webmasters doing.

Here are the most common forms of search engine over-optimization I
see around:

1. Repeating the main keywords over and over again in the body
of the article to increase the keyword density.

2. Using the bold and italic typefaces over and over again on the
main keywords of the page.

3. Creating footer links with optimized and unnatural anchor texts
pointing to internal pages.

4. Getting backlinks from low quality sources (e.g., web directories
and dofollow blogs) with optimized and unnatural anchor texts.

5. Getting too many backlinks with the same anchor text.

6. Exchanging with or buying links form low quality or unrelated
websites.

These tactics might work in the short term, as the person applying
them might see an increase in the search rankings and organic
traffic.
