The Meaning of Search Spider in SEO

Hi,
If you have read articles and books with search engine optimization information, you must have come across the words search spider. A search spider is software that follows links in the internet, taking content from different sites and adding it to the search engine. A search spider offers more opportunities to find and re-index your site. The more times they find links to your site, the more times they will stop by and visit. This has been true since spiders began. Recently there has been an incredible amount of attention paid to links. That's because search engines such made a decision that the number and quality of links to your site will directly impact its rankings in the search results.

Another important use of a search spider is to follow links from one page to another. This is the main reason why links to your site are more important in the ranking of the site by the search engine. The search spiders play a huge role in the search engine optimization system. Because so many web masters have submitted their sites, the search engines have responded by putting more emphasis on sites that their spiders find naturally and less emphasis on sites submitted directly. So, being found is better than submitting directly. This is the main reason why most search engines prefer using the search spider system.

Most search engines use search term frequency as a primary way of determining whether a document is relevant. Therefore, a document that repeats the word you are searching over and over is likely to turn up near the top of your list. If your keyword is a common one, or if it has multiple other meanings, you could end up with a lot of irrelevant hits. And if your keyword is a subject about which you desire information, you don't need to see it repeated. The information on the word that you're interested in is important and not necessarily the word itself. The search spiders help the system to get the information and organize it.

However in some advanced search engines systems both the frequency and the positioning of keywords to determine relevancy take place with the help of search spiders. During this search if the keywords appear early in the document or in the headers, this increases the likelihood that the document is on target. A common method used in this process is to rank hits according to how many times the keywords appear and in which fields they appear. Another method is to determine which documents are most frequently linked to other documents on the Web. The reasoning here is that if other person consider certain pages important, you also as a visitor to the site should consider visiting it.
