How Google works
Google uses a special algorithm to determine search results. Google makes public some facts and factors that are part of their algorithm but the specifics are kept private. It uses automated programs, crawlers to generate search results. These crawlers look at the content on pages of a website, along with other factors, to determine how a website will rank. Google has a large index of keywords that help determine search results.
What sets Google apart in how it ranks pages is their trademark factor called PageRank which assigns web pages a relevancy score.
A Web page’s PageRank depends on a few factors:
– The frequency and location of keywords within the Web page: If the keyword appears only once within the body of a page, it will receive a low score for that keyword.
– How long the Web page has existed: People create new Web pages every day, and not all of them stick around for long. Google places more value on pages with an established history.
– The number of other Web pages that link to the page in question: Google looks at how many Web pages link to a particular site to determine its relevance.
Out of these factors, the third one is the most important. Google sees links pointing to a website as a vote, so the best way to ensure that a website gets ranked on Google is to ensure you have quality content that other sites will want to link to.
