PageRank

PageRank is Google’s link-based algorithm for estimating the relative importance of a web page from the quantity and quality of links pointing to it.

Key takeaways

PageRank measures page importance through backlink quantity and quality.
High-authority links with few outbound links pass more equity.
Internal linking is critical to distribute PageRank across your site.
PageRank is only one of many Google ranking signals.
Focus on earning relevant, authoritative backlinks, not on a forgotten toolbar score.

Understanding PageRank helps SEOs grasp why quality backlinks and internal linking improve search visibility.

Example

A blog post about SEO gets a backlink from the Wikipedia entry for 'Search engine optimization'. Because Wikipedia is a high-authority page with few outbound links to that topic, the blog post receives significant link equity. This helps the blog post rank higher for related queries.

When should I use this?

When planning a link building strategy – focus on quality sources with high authority.
When auditing internal linking – ensure important pages receive enough link equity.
When evaluating competitors – analyze their backlink profiles to understand their authority.

What it is not

Not the only Google ranking factor – PageRank is one of hundreds of signals.
Not a static number – it recalculates as the web changes.
Not measured by the old public toolbar score (0–10) – that metric is obsolete.
Not equal link value from all backlinks – quality and context matter.

Quick start

Identify your top pages (e.g., via Google Search Console).
Audit internal links: ensure important pages have multiple follow links from other site pages.
Research high-authority websites relevant to your niche.
Earn backlinks through guest posts, resources, or original data.
Monitor backlink quality using Ahrefs or Semrush.

Common mistakes

Treating PageRank as a standalone ranking score instead of one signal among many.
Confusing the old public toolbar PageRank score with Google's internal calculations.
Assuming any backlink is equally valuable, rather than considering source quality and outbound-link context.
Ignoring internal linking, which can shape how PageRank flows to important pages on a site.

FAQ

Is PageRank the same as the toolbar score?

No. The public toolbar score (0–10) was discontinued. Google still uses PageRank internally as one of many signals.

Can I improve my PageRank?

Yes. Earn high-quality backlinks from authoritative pages and optimize internal linking to spread link equity.

Does a follow link always pass PageRank?

Yes, unless the link uses a nofollow attribute. Nofollow links do not pass PageRank.
