SEO for Reputation Management

SEO for reputation management is a process for neutralizing negative mentions of your name
in the SERPs. In this type of SEO project, you would strive to occupy additional spots in the
top 10 results to push the critical listing lower and hopefully off the first page. You may
accomplish this using social media, major media, bloggers, your own sites and subdomains,
and various other tactics.


Since one’s own name—whether personal or corporate—is one’s identity, establishing and
maintaining the reputation associated with that identity is generally of great interest.
Imagine that you search for your brand name in a search engine and high up in the search
results is a web page that is highly critical of your organization.

SEO for E-Commerce Sales

One of the most direct monetization strategies for SEO is driving relevant traffic to an ecommerce
shop to boost sales. Search traffic is among the best quality available on the Web,
primarily because a search user has expressed a specific goal through her query, and when this
matches a product or brand the web store carries, conversion rates are often extremely high.

When to employ
Use it when you have products/services that are directly for sale on your website.
Keyword targeting
Paid search advertising is an excellent way to test the efficacy and potential ROI of keyword
targets. Find those that have reasonable traffic and convert well, and then pursue them
further. You’ll often find that the more specific the query—brand-inclusive, productinclusive,
and so on—the more likely the visitors are to make the purchase.
Page and content creation/optimization
You’ll typically need some serious link building, along with internal optimization, to
achieve high rankings for competitive, high-value keywords that bring in conversionfocused
traffic. Manual link building is an option here, but scalable strategies that leverage
a community or customers can be equally, or even more, valuable.

Javascript Math object

The Math object holds a set of constants and methods enabling more complex mathematical operations than the basic arithmetic operators

var root = Math.sqrt(10);

Constants Provided by the Math Object

Property	Description
Math.E	The base of the natural logarithm (Euler's constant e)
Math.LN2	Natural log of 2
Math.LN10	Natural log of 10
Math.LOG2E	Log (base 2) of e
Math.LOG10E	Log (base 10) of e
Math.PI	Pi (p)
Math.SQRT1_2	Square root of 0.5 (equivalently, one over the square root of 2)
Math.SQRT2	Square root of 2

Table 7-4: Methods Provided by the Math Object

Method	Returns
Math.abs(arg)	Absolute value of arg
Math.acos(arg)	Arc cosine of arg
Math.asin(arg)	Arc sine of arg
Math.atan(arg)	Arc tangent of arg
Math.atan2(y, x)	Angle between the x axis and the point (x, y), measured counterclockwise (like polar coordinates). Note how y is passed as the first argument rather than the second.
Math.ceil(arg)	Ceiling of arg (smallest integer greater than or equal to arg)
Math.cos(arg)	Cosine of arg
Math.exp(arg)	e to arg power
Math.floor(arg)	Floor of arg (greatest integer less than or equal to arg)
Math.log(arg)	Natural log of arg (log base e of arg)
Math.max(arg1, arg2)	The greater of arg1 or arg2
Math.min(arg1, arg2)	The lesser of arg1 or arg2
Math.pow(arg1, arg2)	arg1 to the arg2 power
Math.random()	A random number in the interval [0,1]
Math.round(arg)	The result of rounding arg to the nearest integer. If the decimal portion of arg is greater than or equal to .5, it is rounded up. Otherwise, arg is rounded down.
Math.sin(arg)	Sine of arg
Math.sqrt(arg)	Square root of arg
Math.tan(arg)	Tangent of arg

There are several aspects of the Math object that need to be kept in mind. The trigonometric methods work in radians, so you need to multiply any degree measurements by p / 180 before using them. Also, because of the imprecise characteristic of floating-point operations, you might notice minor deviations from the results you expect. For example, though the sine of p is 0, the following code:

alert(Math.sin(Math.PI));

JavaScript and XML

To demonstrate JavaScript, XML, and the DOM in action, let’s use Internet Explorer 5.5 or better to load an XML document containing our employee directory and see if we can manipulate it. First, to load in the document we create an instantiation of Microsoft’s XML parser using the JScript-specific ActiveXobject. Once the object is created, we load the appropriate XML document into memory. In this case, it is the pure XML file of employee records we saw earlier without style sheets or other references.

var xmldoc = new ActiveXObject("Microsoft.XMLDOM");

xmldoc.async = false;

xmldoc.load("staff2.xml");

Once loaded, we can then use the DOM to manipulate it. For example, we can access the root element of the document (<<directory>>) using

var rootElement = xmldoc.documentElement;

then we might alert out its nodeName property as shown in this example.

<<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"

 "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">>

<<html xmlns="http://www.w3.org/1999/xhtml">>

<<head>>

<<title>>XML Demo<</title>>

<<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />>

<</head>>

<<body>>

<<script type="text/jscript">>

<<!--

 var xmldoc = new ActiveXObject("Microsoft.XMLDOM");

 xmldoc.async = false;

 xmldoc.load("staff.xml");



 var rootElement = xmldoc.documentElement;

//-->>

<</script>>

<<form action="#" method="get">>

 <<input type="button" value="show node"

 onclick="alert(rootElement.nodeName);" />>

<</form>>

<</body>>

<</html>>

function deleteLastElement()

{

  var rootElement = xmldoc.documentElement;

  if (rootElement.hasChildNodes())

     rootElement.removeChild(rootElement.lastChild);

}

Really the only difference here is the use of the xmldoc object we created to reference the XML document rather than just plain document, which would reference the HTML Document object. Otherwise, the manipulations are the same as with HTML.

Javascript Image Objects

Properties of Image Objects

Property	Description
align	Indicates the alignment of the image, usually “left” or “right.”
alt	The alternative text rendering for the image as set by the alt attribute.
border	The width of the border around the image in pixels.
complete	Non-standard (but well-supported) Boolean indicating whether the image has completed loading.
height	The height of the image in pixels or as a percentage value.
hspace	The horizontal space around the image in pixels.
isMap	Boolean value indicating presence of the ismap attribute, which indicates the image is a server-side image map. The useMap property is used more often today.
longDesc	The value of the (X)HTML longdesc attribute, which provides a more verbose description for the image than the alt attribute.
lowSrc	The URL of the “low source” image as set by the lowsrc attribute. Under early browsers, this is specified by the lowsrc property.
name	The value of the name attribute for the image.
src	The URL of the image.
useMap	The URL of the client-side image map if the <img> tag has a usemap attribute.
vspace	The vertical space in pixels around the image.
width	The width of the image in pixels or as a percentage value.

The traditional Image object also supports onabort, onerror, and onload event handlers. The onabort handler is invoked when the user aborts the loading of the image, usually by clicking the browser’s Stop button. The onerror handler is fired when an error occurs during image loading. The onload handler is, of course, fired once the image has loaded. Under modern browser implementations that support (X)HTML properly, you will also find onmouseover, onmouseout, onclick, and the rest of the core events supported for Image.

Javascript The + Operator

The binary + operator adds numeric operands or concatenates string operands:

1 + 2 // => 3
"hello" + " " + "there" // => "hello there"
"1" + "2" // => "12"

When the values of both operands are numbers, or are both strings, then it is obvious
what the + operator does. In any other case, however, type conversion is necessary, and
the operation to be performed depends on the conversion performed. The conversions
rules for + give priority to string concatenation: if either of the operands is a string or
an object that converts to a string, the other operand is converted to a string and concatenation
is performed.
