How Search Works
When you do a search on Google you are not searching the web; you are searching Google’s index of the web. The index is created with programs called spiders that follow the links they find to build a picture of the content of the web.
When you do a search there might be many thousands of pages with related information but how does Google decide the ones required. Search – Google asks a number of questions including:
- How many times does the page contain the keywords?
- Do the keywords appear in the title?
- Do the keywords appear in the URL?
- Are the keywords directly adjacent?
- Are there synonyms for those words?
- Is this page on a quality website or is it low quality?
- What is this page’s PageRank? PageRank is a formula invented by the Google founders Larry Page and Sergei Brin that rates a webpage’s importance by looking at how many outside pages point to it and how important those links are.
- Finally, we combine all those factors together to determine each page’s overall score and send you back your search results about 0.5 seconds after submitting your search.
- Google is committed to providing useful and impartial search results.
- No payments can be made to influence the results.
- The results page includes the PageTitle and a snippet of text to assist searchers finds the information they are after.
