How Search Engines Work


allseoknowledgeSearch engines work with a number of different algorithms that can be called "spiders" which search or "crawl" the web for sites that are relevant to specific keywords users input. While these algorithms become quite complicated and watch a number of different aspects of web sites are a few key components that search engines look for in their searches.
Some of the important factors search engines are:
  • Links
  • Content
  • On-Page Factors

links:
When a site links to other web could be seen by a search engine spider as a vote for that website. In short, if site A links to site B, which is essentially a vote for site A to site B. The more links coming into a more the site is seen as valuable content that can benefit a user. The greatest power that the site has to issue the initial vote (a place in my example) the incoming link value is in general.


Content:
The content also plays an important factor for websites. Web sites with content that matches very closely to the search words allows customers to search engines for a better user experience. Search engines consider sites with high quality content to have more authority on a subject, as individual consumers to go to the more experienced professional or knowledgeable for advice or service quality. The more authority a site has, the more relevant it is considered that the consultation of a customer to meet customer needs for the search.


On-Page Factors:
There are a number of pages of the factors that play an important role in the ranking of search engine sites. Sites with good page titles and headings that relate to the search words, for example, tend to have more weight than the pages where titles and headings are not related to search terms however, is its content. Proper use of H1, H2 and H3, including the headers that relate to specific search terms on web pages can help strengthen the web page ranking that simply describe the subject content.


Complex algorithms to combat spam:
In each of these areas search engines are constantly waging a war against spammers link post links to a wide range of sites which seek to increase its relevance to the particular conditions. Some Web site developers use this to your advantage to get the search engine ranking and attract more traffic. To counter these search engines are junk bonds regulate the development of increasingly complex algorithms (with thousands of factors affecting the results of search engines) to search the web, ignoring or elimination of these sites shade.
