So what happens when you do a web search? The first thing to remember when you do a Google search is that you aren’t actually searching the web, you are searching Google’s index of the web, or at least as much of it that Google can find.
This is done with software programs called spiders. Spiders start by fetching a few web pages, then they follow the links on those pages and fetch the pages they link to and then follow the links on those pages, and so on until they have indexed a pretty big chunk of the web.
When you type in a query, the google software searches the indexed pages to find every page that includes those searched terms. Sometimes there are millions (even billions) of possible results. So how does Google decide to put a specific site on page one?
By asking more than 200 questions – like;
- How many times does this page contain your keywords?
- Is it in the title, the URL, the descriptions?
- Does the page include synonyms for the keywords?
- Is this page from a quality website, or a low quality website…even spammy?
- What is this pages pagerank?
Finally they combine all of those factors together and to produce each page’s overall score and send you back your search results.
NOTE: Google does not accept payment to add a site to their index, update it more often or improve it’s ranking.
