Search Engines Robots SEO – How they work
September 14, 2009 | Posted by Wolf |
Search engines bring your web site to the notice of the potential customers. Therefore you should know how they work and how they give information to the customers starting a search.
We are going to talk about search engines robots, also known as crawlers or spiders. They are automated programs managed by the system search engine.
Spiders are used to index web sites. When you submit your web site to a search engine, the spider will index it. How? It reads content and meta tags of your web site, and then follows each link that the site connects. These information are sent to a central repository where they are, finally, indexed. Spiders periodically revisit indexed sites to verify any information that has changed.
Spiders, often, don’t index all the pages of a web site: title, meta tags, content and URL are only some of the things that play a fundamental role on this.
When we ask a search engine to find information it seeks them through its created index… it does not seek them through the Web. Every search engine uses its algorithm in search indexes so different search engines establish different ranking.
Search engines can detect also stuffing and spamdexing (search spam or search engine spam).
