PageRank is an algorithm used by Google Search to rank web pages in its search engine results. It assigns a numerical value (PageRank score) to each page based on the quantity and quality of links pointing to it. The algorithm was named after Larry Page, one of Google’s co-founders.

PageRank is like a voting system where web pages are ranked based on the number and importance of links they receive from other pages. The more and higher-quality votes a page gets, the higher its PageRank score and, potentially, its position in search results.


Key Points:

Link Authority: PageRank evaluates the authority or importance of a webpage based on the links pointing to it.

Link Quality: Not all links are equal; quality and relevance of links play a crucial role in determining PageRank.

How PageRank Works:

Link Votes: Each link to a page is considered a “vote” for that page. The more votes, the higher the PageRank.

Quality Matters: Links from pages with higher PageRank contribute more to the receiving page’s PageRank.

Updates and Changes:

Over the years, Google has evolved its ranking algorithms, and while PageRank is still a factor, it is now one of many signals used to determine search rankings.

Toolbar PageRank:

Google used to provide a public representation of PageRank through the Google Toolbar. However, this feature was discontinued in 2016, and Google no longer publicly discloses PageRank scores.

Importance in SEO:

Link Building: PageRank emphasizes the importance of acquiring high-quality backlinks to improve a webpage’s authority.

Content Quality: Creating valuable and shareable content increases the likelihood of earning quality backlinks and, in turn, improving PageRank.


If a popular and reputable website links to a specific blog post on another website, it’s like giving a vote of confidence to that blog post, potentially boosting its PageRank.

Why it Matters:

Search Rankings: While not the only factor, PageRank influences a webpage’s position in Google’s search results.

Link Authority: PageRank encourages the acquisition of authoritative and relevant links, contributing to a website’s overall authority.

Link Ecosystem: Understanding PageRank helps webmasters and SEO professionals navigate the complexities of the link-building ecosystem.

In summary, PageRank is an algorithm used by Google to assess the importance and authority of web pages based on the quantity and quality of links pointing to them. While it is just one of many factors in Google’s ranking algorithm, it has historically played a significant role in determining the visibility of web pages in search results.
