Know whose metric you are reading
Domain Authority and Domain Rating are names from third-party providers. They are not interchangeable measurements and should not be treated as a Google score. Ahrefs describes Domain Rating as a measure of a domain’s backlink-profile strength relative to others in its database.
Write the provider name next to every score in your research sheet. Otherwise a list containing “DA 40” and “DR 40” can look more comparable than it is.
Choose a tool by the job
| Research question | Useful input | What to verify |
|---|---|---|
| Who references this topic? | Backlink explorer | The actual linking page and its context |
| Which pages get search visibility? | Your Search Console data | Query, page, country, and device filters |
| Is this placement relevant? | Manual editorial review | Audience, content quality, and disclosure |
Tool availability and subscription limits change. Check the provider’s current terms rather than relying on an old “free tools” list.
Use a consistent comparison
- Define the market and audience you care about.
- Compare the same type of site with the same tool and on the same date.
- Open the referring pages instead of trusting summary numbers.
- Look for a credible reason your audience would use the site.
- Record limitations and avoid forcing a single score into a yes-or-no decision.
Do not buy a number
A high third-party score does not validate a paid link package or make ranking manipulation compliant. Check the placement itself and Google’s link-spam guidance. A business relationship, sponsorship, or advertisement should be handled transparently and qualified appropriately.
The most useful result of this research may be a relevant publication to learn from, a resource your customers already use, or a gap your own site can fill. Those are concrete opportunities; an isolated authority score is only a clue.
