Trust and citation, separately
Two numbers rather than one blended score, because a domain with many links from poor sources and one with fewer from good ones are different, and one number hides that.
Domain authority
One honest number for how much weight a domain carries
Trust and citation scores for any domain, refreshed weekly and kept as a trend — so you can tell a domain that is growing from one that peaked three years ago.

What it is
Authority scores are how the industry compares domains quickly. They are not a Google metric and nobody should pretend otherwise, but they are the best available shorthand for whether a domain has earned genuine links from places that themselves earned links.
What makes a score useful is history. A domain sitting at the same score for two years and a domain that has climbed to it in six months look identical in a single reading and are completely different propositions. We keep the readings so you can see which one you are looking at.
What you get
The scores, the trend, and enough context that the number means something.
A weekly trend line
Every reading kept, so you see direction and not just position.
Any domain you name
A site you are buying, a site offering you a link, a competitor, or your own.
Beside your link profile
Authority and backlinks on the same screen, because the first is a summary of the second.
Batched, so it is cheap
Readings are taken a thousand domains at a time, which is why this costs what it costs rather than what a per-lookup tool charges.
For resellers, across a whole book
If you manage client sites, the reseller SEO-data add-on gives you this across all of them for one flat price.
How it works
Name a domain
Yours, a client's, or one you are considering.
Weekly readings
Trust and citation are refreshed once a week and each reading is kept.
Read the direction
The trend is the product. A rising score and a falling one tell you opposite things about the same number.
What it costs
One monthly price for your account.
Domain SEO Score
$19.00/month
Add-ons are bought per site from your dashboard and appear on your normal invoice — no separate account, no second bill and no minimum term. Prices exclude tax, which is worked out from your billing country at checkout.
What this is not
It is not a Google ranking factor and we will not sell it as one. No third-party authority score is used by any search engine; they are estimates built from crawls of the public web.
What they are good for is comparison and triage — deciding which of twenty link offers is worth answering, or whether a domain somebody wants to sell you has anything behind it. Used for that, they are one of the most useful cheap numbers in SEO.
Questions
Is this Google's PageRank?
No. Google has not published PageRank for domains since 2016. This is a third-party estimate built from a web-wide link crawl, and it is useful for comparison rather than as a prediction of ranking.
Can I check a domain before I buy it?
Yes, and it is one of the best uses of this. Add the domain, take a reading, and look at what the link profile behind the score actually is.
Why two scores instead of one?
Because volume and quality are different questions. A domain can have enormous citation and poor trust, which usually means a lot of links from places that do not matter.
Do I have to host with you to buy this?
No. Domain scoring works on any domain, wherever it is hosted. You need a Zinn Digital® account, which is free to create, and you add the domain you want watched.
Can I cancel whenever I want?
Yes. It is billed monthly with no minimum term, and cancelling stops the next charge. The history we have already collected for you stays readable for as long as your account is open.
What happens if my account is suspended or unpaid?
Checks stop while the account is not in good standing, and start again by themselves once it is — you do not have to ask. Everything already collected stays visible in the meantime, with its real age shown, so you are never looking at stale data that is pretending to be current.
