A PageRank is a trademark of Google and patent of Stanford University that was developed by Larry Page and Sergey Brin and began being developed in 1995. PageRank helps sort web pages on the Internet by running them through an algorithm and giving it a numerical weight. This "weight" is then used to sort results when a user uses the Google search engine.
What determines PageRank?
A PageRank is determined by different factors. Although it is not official, the list below contains some factors believed to increase or decrease the overall PageRank.
- The most important factor is how many pages link to the page. Pages with higher PageRank values that link to the page give that page a higher value.
- The quantity of keywords matched with the search query, their position on the page, and in some cases how they are formatted (e.g., bold). Also, keywords matched in the domain and other parts of the page URL (e.g., directory and file) are believed to play a factor in PageRank.
- How often new content and pages are created.
- The last time the page was updated.
- Outbound links to other pages. Linking to poorly ranked pages, link farms, or having several broken outbound links can reduce the overall PageRank.
- The age of the page and domain hosting the page.
- How many years the domain is registered.
- How fast the web page loads.
