backrub-Back in the olden days of 1998, there were no Google rankings and no search engine optimization. In 1998, a grad student called Larry Page created a web crawler that could find out how often a site was being linked to by other websites. This was to rank each site according to how important it was and no longer would search engines rely on humans or humans using spiders to find out which sites were important.

What is the backrub algorithm
The Google backrub algorithm is a search engine ranking algorithm that was
developed by Google. It was designed to help Google rank web pages based
on the number and quality of inbound links. The algorithm looks at the number of inbound links to a page, as well as the quality of those links, in order to determine how high to rank the page in search results.
Where did the backrub come from?
The backrub algorithm was created by Larry Page and Sergey Brin, the co-founders of Google. It was designed to be a more efficient way of ranking webpages than the existing algorithms at the time.The backrub algorithm looks at the number and quality of inbound links to a webpage to determine its importance. The thinking behind this is that if a lot of other websites are linking to a particular webpage, then it must be important and should be ranked higher in search results.
Initially, the backrub algorithm was only used by
Google, but it has since been adopted by other
search engines such as Bing and Yahoo!.
The BackRub Crawler
The BackRub crawler was the Google search engine’s original web crawler. It was designed by Larry Page and Sergey Brin while they were PhD students at Stanford University. The crawler began operation in 1996 and was used to build the Google index.The BackRub crawler was designed to be highly scalable. It used a distributed architecture, with each machine in the system responsible for a portion of the crawling process. This allowed the system to crawl billions of
pages very quickly.
The BackRub crawler had a number of unique features. First, it used PageRank to prioritize which pages to crawl next. Second, it stored its data in an inverted index, which made retrieval very fast. Third, it had a robust link-following algorithm that ensured that all reachable pages would be found and crawled.
The BackRub crawler was very successful, and it laid the foundation for Google to become the largest search engine in the world.
PageRank
Google’s PageRank algorithm is a numerical method used by the search engine to rank web pages in their search results. The algorithm was named after Google co-founder Larry Page and was introduced in 1998.
PageRank is calculated by assessing the number and quality of links to a page. A link from a high-quality, trusted website is worth more than a link from a low-quality or untrusted website. The algorithm also takes into account other factors, such as the anchor text of links (the text that is linked to the page), the reputation of the linking website, and whether the link is follow or nofollow (a tag that can be added to links to indicate that they should not influence the PageRank of the linked-to page).
The PageRank algorithm is just one of many factors
that Google uses to determine the ranking of web pages
in their search results. Other important factors include relevance ( how well a page matches a user’s search query), freshness ( how recent the content on a page is), and engagement ( how often users click on a particular result).
How do I check my page rank?
In order to check your page rank, you can use the Google PageRank Checker tool. This tool will allow you to see your page rank for any given URL.
