How to Check Domain Authority
Domain authority is a score that predicts how well a website is likely to rank in search results, based mainly on the quantity and quality of the backlinks it has earned. It isn't a Google metric, it's a third-party estimate created by SEO tools, but it's a useful shorthand for a site's overall strength and a handy way to compare yourself against competitors. This guide explains how to check domain authority for any site for free, how to read the number honestly, and what actually moves it.
Step-by-Step Guide
Understand what domain authority is (and isn't)
Domain authority (and similar scores like Domain Rating) is a 0-100, log-scaled estimate of a site's ranking strength, built from its backlink profile. It's not used by Google and doesn't directly cause rankings. Treat it as a comparative signal, useful for benchmarking against competitors, not as a target to chase for its own sake.
Check your own domain authority with a free tool
Enter your domain into any authority checker to get your current score plus the backlink data behind it, referring domains, total backlinks, and top linking sites. Because the score is modeled from public backlink data, no access to your site is required. Note the number, but focus on the referring‑domain count driving it.
Check any competitor's domain authority
Run your main competitors through the same checker. This tells you roughly how much authority you need to compete and, more importantly, reveals their backlink sources. A competitor's linking domains are a ready-made list of sites that link to businesses like yours.
Compare like with like
Authority scores only mean something in context. A score of 40 might be strong in a niche industry and weak in a competitive one. Always compare against the specific sites ranking for your target keywords, not against giants in unrelated fields.
Improve authority by earning quality links
Since authority is built from backlinks, you raise it by earning links from relevant, trustworthy sites: create genuinely useful content and tools, get listed in reputable directories, earn coverage with original data, and reclaim mentions of your brand that aren't yet linked. Quality and relevance beat volume.
Track the trend, ignore small wobbles
Authority scores update periodically and can shift by a point or two for reasons outside your control. Don't react to minor changes. Track the trend over months alongside your referring‑domain growth, that direction is what reflects real progress.
Pro Tips
- Referring domains drive authority, growing the number of unique quality sites linking to you is the real lever.
- Use authority as a comparative benchmark against sites ranking for your keywords, not as a goal in itself.
- A competitor's backlinks are your best link prospect list, they already link to sites in your niche.
- Free tools and original data earn links passively, build assets worth linking to rather than chasing links one by one.
Common Mistakes to Avoid
Treating domain authority as a Google ranking factor
Google doesn't use domain authority, it's a third-party estimate. Chasing the score directly, or buying links to inflate it, wastes effort and risks penalties. Focus on earning quality links; the score follows.
Comparing against irrelevant sites
A score only matters relative to your actual competitors. Benchmarking against huge, unrelated sites is discouraging and useless. Compare against the pages that rank for the keywords you want.
Obsessing over the number instead of the backlinks
The score is a summary; the backlink profile behind it is the actionable part. Studying which sites link to you and your competitors is far more useful than watching a single number tick up or down.

Frequently Asked Questions
How can I check domain authority for free?
Enter any domain into a free domain authority (or domain rating) checker to see its score plus the backlink data behind it. Because the score is modeled from public backlink data, you can check any website, yours or a competitor's, without any access to it.
What is a good domain authority score?
There's no universal 'good' number, it depends entirely on your niche. Compare against the specific sites ranking for your target keywords: matching or exceeding their scores from quality links is the practical goal. A 40 can be strong in one industry and average in another.
Is domain authority a Google ranking factor?
No. Domain authority is a third-party estimate created by SEO tools, not a metric Google uses. It's a useful shorthand for comparing sites, but Google ranks pages using its own signals. Improve real signals, quality links and content, and the score reflects that.
How do I increase my domain authority?
Earn more backlinks from relevant, trustworthy websites: publish useful content and free tools, get listed in reputable directories, earn coverage with original research or data, and reclaim unlinked brand mentions. Quality and relevance matter more than raw link count.
How long does it take to improve domain authority?
Months, not days. Authority grows as you steadily earn quality links and the tools recrawl the web. Track referring-domain growth month over month; the score follows the trend rather than jumping from any single link.
