How to use bulk DA/PA checking in your workflow
Single-domain checks are fine for spot-research. The real value of DA/PA is when you compare a batch side-by-side: your site against your 4 closest competitors, or a prospect list of 10 link-building targets, or a row of 8 candidate guest-post sites.
Three high-leverage uses
- Competitor gap analysis. Drop in your domain plus your 5 closest competitors. The gap between your score and the median competitor score is the number of authority points you need to climb.
- Guest-post vetting. Before pitching, run the prospect list. Anything under DA 20 is rarely worth the effort. 30+ is the floor for most agencies; 50+ is high-value.
- Link-buy / sponsorship vetting. Sellers love to inflate metrics. A 10-domain bulk check exposes the real authority of every domain in a partnership pitch in 5 seconds.
One caveat: never make a buy/no-buy decision on authority score alone. A DA 60 site with traffic in the wrong country or in a totally unrelated niche is worth less than a DA 25 site in your exact vertical with engaged readers.

Frequently Asked Questions
What is Domain Authority (DA)?
Domain Authority is a 0–100 score that predicts how well a website will rank on search engines. It is based on the size and quality of the site's backlink profile. Originally coined by Moz, the score we show here is the equivalent Semrush 'Authority Score' — same scale, same interpretation, but built on a larger link index.
What's the difference between DA and PA?
DA scores the whole domain. PA (Page Authority) scores an individual URL. Both use the same 0–100 scale. For most SEO decisions DA is the one that matters; PA is useful when comparing competing pages for the same keyword.
How is DA calculated?
By counting referring domains, weighting each by its own authority (a link from CNN counts more than a link from a random blog), and grading the overall trust signals of the link profile. Spammy patterns drag the score down.
What's a good DA score?
It depends on your industry. 0–20 = new site, 20–40 = growing, 40–60 = solid established business, 60–80 = market leader, 80+ = global brand. To rank on page 1 you generally need to be within 20 points of the sites already there.
Why are you limited to 10 domains?
10 is enough for most competitor research without burning through the free API quota. Sign up for unlimited bulk checks and CSV exports.
How do I increase my DA?
Earn high-quality backlinks. There is no shortcut. Guest posts, original research, free tools, and outreach to sites that link to competitors are the four reliable methods. Avoid PBNs and paid link networks — they drop the score, not raise it.
