Effective search engine optimization may require changes to the HTML source code of a site and to the site content. SEO tactics should be incorporated into the website development and especially into the menus and navigation structure.
When you submit your site to a search engine, you only need to specify the top-level (home) page. You do not need to submit each page. The search engine will find the rest based on your links .
HTML size
Page size matters because search engines limit size of a cached page. For example, Google will only cache a full page if the size of its HTML is less than 101 Kb (images and external scripts are not included). Yahoo! caches text of up to 500 Kb per page. This means if your HTML page is too large, search engines will not cache the full page, and only the top part of the text will be searchable.
Last modified
This attribute shows how old the document is. It is taken from the server response to HTTP request. You can see if your page has been updated lately.
Same color text and background
If the color of the text on a page is close to the background color, the text becomes almost invisible. As a rule, this technique is employed to populate a page with keywords without damaging its design. Since it is considered as spam by most search engines, we suggest that you do not try it. NOTE: If a text of the same color as the background is found on the analyzed page, hover cursor on the parameter value (in our case - Yes) to see a floating hint for the improper text and tag.
Tiny text
If a page uses Cascading Style Sheets and there are fonts smaller than 4 pixels, they are reported as tiny texts. Most search engines consider tiny texts as an abusive practice - this is why you should avoid using them. NOTE: If the instance of tiny text is found on the analyzed page, hover cursor on the parameter value (in our case - Yes) to see a floating hint for the improper text and tag.
Immediate keyword repeats
The same keyword repeated one after the other a few times, for example air tickets on-line, air tickets, air tickets, air tickets, air tickets in Hong Kong is a questionable trick. For this example, there will be three repetitions reported, because the keyword was placed three times in a row after it was used first. Such repetitions are considered as spam by most search engines.
Controls
If the page has HTML tags (HTML only, not other scripts) that create controls, it will be mentioned in the report. Try to avoid too many controls on your page, especially in the top area, since it may decrease your keyword prominence and result in low rankings.
Frames
Frames use is reported here. Not all search engines support frames, i.e. can follow from a frameset page to content frames and index texts. If your website consists of frames, and you cannot redesign it, you can solve this problem by putting the content of an optimized page with links to other pages into a <NOFRAMES> HTML tag.
