If you need to customize and search engine optimize your blog/site deeply, you can follow my my complete Customization and SEO guide provided below. You need some HTML, XML and CSS skills to work it out.
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.
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, I suggest that you do not try it.
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.
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.
