Each search engine to produce various classifications, because they use different algorithms to search through the index. One of the things that the algorithm of a search engine scans for is the frequency and location of the keywords on a Web page, but it can also detect keyword stuffing or artificial spamdexing. Then algorithms to analyze how the keywords on a Web page, but it can also detect keyword stuffing or artificial spamdexing. Then algorithms to analyze how the pages link to other Web pages. By monitoring how the pages to each other (importance of the anchor text), an engine can both determine what is on a page, if the keywords pages are similar to keywords on the original. Search engines also check the number of websites that link to your site ( backlinks ).

Do you know, search engine used to rank sites according to their density of keywords. Well placed, you just need to add your main keywords on your page at the beginning of your first paragraph, and then to include it in all your points. It was also a good thing to try to get your word at the end of your web page. To stay in profits, Google needs to deliver and give quality to web searchers.

Their new algorithm is based on the relationship and not on the density of keywords ( you still need to classify keywords, but its not so easy now ). Now, well placed to your keywords, you need to get a large number of incoming links (called outbounds links) that point to your site. While many sites have a link ( to vote ) to you, that is an indication that you have a quality site with quality content, and therefore, you deserve a better ranking than other sites with little or no ties.
