In writing a post I start looking at any web pages with the eye of a search engine spider, because it makes post got easier to rank high in optimizing certain keyword phrase. The first thing to cast in mind here is that the search engines rank pages instead of sites. What this means is that you will not achieve a high ranking for your site by attempting to optimize your main page for twenty different keyword phrases.

However, different pages of your site will appear up the list for different key phrases if you optimize each page for just one of them. If you can’t use your keyword in the domain name, no problem – use it in the URL of some page within your site, such as in the file name of the page. This page will rise in relevance for the given keyword phrase. All search engines will show the URLs of specific pages when you search, not just the root domain names like www.yourdomain.com but the paths like www.yourdomain.com/your-best-keyword-phrase.html

In addition, search engine spiders also have a limit on loading page content. For example, Googlebot, the Google crawling spider robot, will not read pages with more than 100 KB, even though it was instructed to crawl if there are keywords at the end of the page. So if you use keywords somewhere beyond this limit, it obviously is invisible to spiders. Therefore, get used to make a light loading page by reducing unnecessary scripts and styles.

There are many more examples of relevancy indicators a spider considers when visiting your page, such as the proximity of important words to the beginning of the page. Here, as well, the spider does not necessarily see the same things a human visitor would see. For instance, a left-hand menu pane on your Web page. People visiting your site will generally not first pay attention to this, focusing instead on the main section. The spider, however, will read your menu before passing to the main content – simply because it is closer to the beginning of the code.

Remember: during the first visit, the spider does not yet know which words your page relates to! Keep in mind this simple truth. By reading your HTML code, the spider (which is just a computer program) must be able guess the exact words that make up the theme of your site. Then, the spider will compress your page and create the index associated with it. To keep things simple, you can think of this index as an enumeration of all words found on your page, with several important parameters associated with each word: their proximity, frequency, etc.

Certainly, no one really knows what the real indices look like, but the principals are as they have been outlined here. The words that are high in the list according to the main criteria will be considered your keywords by the spider. In reality, the parameters are quite numerous and include off-the-page factors as well, because the spider is able to detect the words every other page out there uses when linking to your page, and thus calculate your relevance to those terms also.

When a Web surfer queries the search engine, it pulls out all pages in its database that contain the user’s query. And here the ranking begins: each page has a number of “on-the-page” indicators associated with it, as well as certain page-independent indicators (like PageRank). A combination of these indicators determines how well the page ranks.
