The name "PageRank" plays off of the name of developer Larry Page, as well as of the concept of a web page. The word is a trademark of Google, and the PageRank process has been patented (U.S. Patent 6,285,999). However, the patent is assigned to Stanford University and not to Google. Google has exclusive license rights on the patent from Stanford University. The university received 1.8 million shares of Google in exchange for use of the patent; it sold the shares in 2005 for $336 million.
After finding websites that have good metrics, you have to make sure the website is related to your site. For each competitor backlink, try to understand how your competitor got that link. If it was a guest article, send a request to become a contributor as well. If it was a product review by a blogger, contact the writer and offer them a good deal in exchange for a similar review.
A breadcrumb is a row of internal links at the top or bottom of the page that allows visitors to quickly navigate back to a previous section or the root page. Many breadcrumbs have the most general page (usually the root page) as the first, leftmost link and list the more specific sections out to the right. We recommend using breadcrumb structured data markup28 when showing breadcrumbs.
