Semrush Domain Overview, and the Authority Score trap

Domain Overview is the report I open most and think about least. Type a domain, get a screen, decide in thirty seconds whether that competitor is worth an hour.

It is also where the single most expensive misunderstanding in this toolkit lives, and it has a number attached to it.

Authority Score is not a goal

Authority Score is a 0 to 100 figure Semrush calculates from link data, estimated traffic and spam signals. In my walkthrough, semrush.com itself scores 83, which is genuinely useful calibration: that is roughly the ceiling, held by a company whose entire business is search.

What it is not: a Google signal. Google has never seen it and does not use it. It is one vendor’s model of authority, sitting beside Moz’s Domain Authority and Ahrefs’ Domain Rating, all three disagreeing about the same website because all three are guesses built differently.

So “how do I increase my Authority Score” is the wrong question, and every hour spent on it is an hour not spent on the thing that moves it as a side effect. The right question is narrower: is the gap between me and the domains ranking for my target keywords big or small? A gap of 10 means compete head-on. A gap of 50 means go long-tail and stop reading their head terms.

That’s the only decision this number should ever drive.

Calibrate it once against sites you know

Five minutes, and it permanently changes how you read the number.

Run Domain Overview on your own site, on the two competitors you think about most, and on one site you know is enormous. Write the four scores down. Now you have a scale with real reference points on it instead of an abstract 0 to 100, and semrush.com at 83 is your ceiling marker.

Do the same thing in Ahrefs or Moz if you have access, on the same four domains. The scores will disagree, sometimes by twenty points, and the disagreement is the most informative result of the whole exercise. Three vendors looking at the same link graph and reaching different conclusions is a demonstration that none of them is measuring a real quantity. After that it becomes very hard to take any single one of them literally, which is the correct place to end up.

The screen, read in the right order

Six things load at once, and there’s an order that turns them into a judgement.

1. Authority Score. Only as the gap between them and you.
2. Organic keywords and estimated traffic. Volume of coverage. The traffic figure is a model, and the recording says so out loud: it can be above or below reality.
3. Paid keywords. The most under-read box on the screen. A competitor spending heavily is telling you which terms convert, before you’ve done any research.
4. Top organic pages. Where their traffic actually concentrates. Usually two or three URLs, and usually not their homepage.
5. Backlink total. Scale only. The composition matters far more and it is not on this screen.
6. Traffic by country. The one that quietly kills bad competitor choices, when the domain you were benchmarking against turns out to earn in a different market.

If steps one to four are interesting, keep going. If not, you have spent thirty seconds instead of an afternoon, which is the entire value of this report.

Where to go next, and when

Domain Overview is triage. It answers “is this worth my time” and nothing else, and every deeper question has its own report.

Their keywords, in full. Organic Research. Domain Overview shows you a sample; Organic Research is the list you can filter and export.

Their traffic composition. Traffic Analytics, with the same estimate caveat and the same calibration exercise.

Their links. Backlink Analytics, where the composition question the backlink total dodges finally gets an answer.

Your gap against them. Keyword Gap, which is the only report on this list that produces a to-do rather than an observation.

The failure mode is stopping here and calling it competitor research. A screenshot of Domain Overview in a proposal is a screenshot of six estimates, one of which is not a Google metric and none of which tells you what to do on Monday. It is where competitor research starts.
