Why it matters

Understanding domain authority and PageRank is essential for SEO competitive analysis, backlink prospecting, and domain acquisitions. Rather than paying expensive monthly subscriptions to SEO platforms that monitor your search history, this tool runs 100% in your browser using mathematical PageRank modeling and authoritative benchmarks with zero network queries.

When to use it

Use when evaluating backlink opportunities, vetting expired domains for acquisition, analyzing competitor search strengths, or demonstrating internal linking PageRank distribution.

Common questions

What is the difference between PageRank and Domain Authority?

PageRank is Google's original mathematical link algorithm measuring recursive link equity on a logarithmic 0–10 scale. Domain Authority (DA) is an industry metric (pioneered by Moz and Ahrefs) measuring overall domain ranking potential on a 0–100 scale.

How is PageRank calculated mathematically?

PageRank models a random surfer navigating a web graph with a damping factor d (typically 0.85). The score of page A is (1 - d) plus d times the sum of PageRank from each linking page divided by its outbound link count: PR(A) = (1 - d) + d * sum(PR(Ti) / C(Ti)).

How does the PageRank Simulator work?

The simulator runs Google's exact power iteration algorithm over a user-configurable network of pages and links, computing the convergence of link equity across multiple iterations in real time.

Does this tool track my domain searches?

No. All domain parsing, authority scoring, algorithmic graph calculations, and bulk tests execute purely in your local browser using client-side JavaScript. No domains or queries are recorded on any server.
