Domain Comparison
Short answer
Compare two domains on a public, link-based authority score (0–10) — a relative signal for sizing up a competitor, not a Google ranking factor.
What it does not do: The score is a third-party, link-based estimate, not a Google metric; it compares two domains at a time and says nothing about traffic or rankings.
What It Does
Compares two domains on a public, link-based authority score — a 0–10 estimate for each domain from the same free source. It is a comparative proxy for how strong each domain's links are, not a Google metric: Google does not use third-party authority scores for ranking.
Why It Matters
"How do we stack up against this competitor?" comes up all the time. A shared authority score gives a quick, like-for-like read on link strength before you dig into content and links — as long as you treat it as an estimate, not a ranking factor.
How It Works
-
Enter your domain and the competitor domain
-
We look up the authority score for each domain from the same free source
-
Return both scores side by side so you can see at a glance who has the edge
-
No traffic, keyword or backlink data — this check is authority only
Sample input + output

Frequently Asked Questions
- Is domain authority a Google ranking factor?
- No. Google does not use third-party authority scores. They are estimates built from public link data, useful for comparing domains with each other.
- Can I compare more than two domains?
- No — this check compares two domains at a time. Run it again with a different competitor to check a third.
- How fresh is the data?
- Each domain pair is cached for up to 7 days to keep the check free to run — check again after that for an updated score.
