You can use these web spiders to index access to web pages across the Internet through search engines. A spider will search the pages of a submitted website and index them. What the spiders will do is read your content of the site, meta tags and even follow the links you have on your pages. Your data will be indexed in a certain spot, and that is where the spider will bring them to. The spider will also help to index those pages which you have links connected to. Sites with hundreds of pages could be a problem, however, because spiders only index a limited amount of pages.

If you update or change your site regularly, the spider should catch it as it returns periodically. The frequency of how often these returns take place is up to the moderators that run the search engines. As a book would have a table of contents, content, and references, so does a spider have similar, with meta tags, content, and links. It is not uncommon for some spiders to have the ability to index over a million pages a day, and examples include Excite, Lycos, Alta Vista, and Google.

The search engine looks for the information in their internal index that is closest to what the searcher types in, and that is how search engine placement is decided. It's not truly searching the web, so if you have a keyword such as "buy management book" in the search engine index, then your website should be in the first page of results for a searcher who types in that word. You will not get the same ranking in every single search engine, because every engine uses a different search algorithm to search their indexes.

Another clue you need to keep in mind is that you should remember the frequency of your keywords, along with where they are located on your web page. If you want to avoid being considered a keyword stuffer, the goal is to keep the keyword density at around 3-7 percent. Another thing that search engines analyze are how the links form and what the linked pages are about. Search engine rankings are improved whenever the pages are linked and related. To summarize - the hidden secret to improved search engine placement is actually learning how the search engine works and using their tools to help your website get higher rankings.
