How the Search Engine Works in a Nutshell

When you submit your site to a search engine, or the search engine follows a link from another site, the search engine will send a “robot” to your site. The search engine robots will then spider your blog. What this basically means is that it will try and follow all links on your site, i.e. links in your site navigation menu, your site content and all other links on your site.
When the robot is done spidering your website, it will add it to the “search engine index”. When a person performs a query in the search engine, it will then return its result page and rank the different websites based on how important the search engine thinks your site is.
