Semrush Rank: what the number means, how it differs from Authority Score, and when to use it

People asking about a Semrush rank mean one of three different numbers, and they are not interchangeable. Semrush Rank is a league table position: it orders the domains in the Semrush database by estimated organic search traffic, so a smaller number means a bigger estimated traffic footprint. Authority Score is a zero to one hundred score estimating a domain overall strength from link data, estimated organic traffic and spam signals. Position tracking is your actual ranking position for specific keywords in specific locations. Work out which one you are looking at before you draw a conclusion, because only the third one is a direct measurement of your own search performance.

The three numbers side by side

Metric	What it is	Scale	Best used for
Semrush Rank	A position in a league table of domains ordered by estimated organic traffic	1 upwards; lower is bigger	Getting a sense of scale when comparing two unfamiliar domains
Authority Score	A composite estimate of domain strength from links, traffic and spam signals	0 to 100; higher is stronger	Filtering a link prospect list and comparing competitors at a glance
Position tracking	Measured rank for your keywords, by location and device	Actual positions	Reporting your own performance and spotting movement

Semrush Rank: what it tells you and what it does not

Semrush Rank is relative and it is built on estimated organic traffic, not on a direct measurement of your site. That makes it useful for one narrow job: quickly understanding whether a domain you have never heard of is large, medium or small, before you spend time on it. A domain in the low thousands is a major site. A domain in the millions is small or new.

What it is not useful for is tracking your own progress month to month. The rank moves when other domains move, when Semrush updates its database and when its traffic estimation changes, so a change in your number can come from somewhere other than your own site. Use your own Search Console data for progress and keep Semrush Rank for comparison of unfamiliar domains.

Authority Score: how to use it without misreading it

Authority Score is Semrush own estimate, in the same family as Ahrefs Domain Rating and Moz Domain Authority. None of them is a Google metric, and the three will disagree about the same site because they are built from different link indexes and different formulas. That is normal and it is not a problem as long as you use them consistently.

• Use it as a filter, never as a decision. It is good for sorting five hundred link prospects into a shortlist, and poor for deciding whether one specific site is worth a placement.
• Read it alongside the traffic estimate. A high score with almost no estimated organic traffic is a sign of a site built for link selling rather than for readers.
• Compare like with like. Scores are not comparable across very different sectors, and a specialist trade publication with a modest score can be worth far more than a general site with a higher one.
• Judge the page, not only the domain. A link from a buried page on a strong domain can be worth less than a link from a well read page on a smaller one.

Position tracking: the number to put in a report

This is the only one of the three that measures your own ranking. To make it trustworthy, configure it carefully once:

• Location and device. Set the country, and the city where you serve a local market. A national average position is meaningless for a business with one shop.
• A defined keyword set. Pick the queries that reflect commercial intent and keep the set stable. Adding and removing keywords every month makes the trend line unreadable.
• Group by intent. Report movement by group, brand, category, comparison, local, rather than as one average, which hides everything useful.
• Record the features on the page. Whether an AI overview, a map pack, a shopping block or a people also ask box sits above you changes what position three is worth.
• Reconcile against Search Console. A rank tracker samples a results page from a chosen location. Search Console reports the positions your real users saw. When they disagree, Search Console is the one to report to a client, with the tracker explaining the movement.

Where each number belongs in a monthly report

• Headline. Clicks and impressions from Search Console, by query group, with conversions.
• Movement. Position tracking for the priority keyword set, grouped by intent, with the biggest gains and losses named.
• Competitive context. Authority Score and estimated traffic for your three closest competitors, as context rather than as a target.
• Link work. New and lost referring domains, with the Authority Score of each new one used as a sorting aid.
• Leave out Semrush Rank unless you are introducing a domain the reader has never seen. In a progress report it invites a question you do not want to spend the meeting answering.

The Semrush Rank questions worth an answer

Is a lower Semrush Rank better?

Yes. It is a league position, so rank 500 describes a much larger estimated traffic footprint than rank 500,000. It is the opposite direction from Authority Score, where higher is stronger, which is the main reason the two get confused.

Does Google use Semrush Rank or Authority Score?

No. Both are Semrush metrics built from its own index and estimates. Google does not publish a domain score. Treat these numbers as useful comparison tools for your own decision making.

Why does my Authority Score differ from my Ahrefs Domain Rating?

Different link indexes and different formulas. Pick one as your working metric, use it consistently, and look at the underlying referring domains when a decision actually matters.

How do I raise my Authority Score?

Earn links from relevant sites that have real readers, keep publishing pages that are worth citing, and remove or disavow nothing unless you have a specific reason to. The score follows the link profile, so work on the profile rather than on the score.

How often should I check these numbers?

Position tracking weekly, Search Console weekly, Authority Score and competitor estimates monthly, and Semrush Rank only when you are sizing up a domain you do not know. Checking a domain level estimate daily produces noise.

A rank with no list

Semrush Rank is a number from a list. Assistants have no list, only an answer on a given day. A brand ranked 40,000 in one tool might be named first for a narrow question, and one ranked 500 might not appear at all.

Measure the answer. Take the questions your buyers ask, ask them in several assistants, and count how often you appear. AI Knows Us gives the count and the sources, so you can set it beside your Semrush Rank in the monthly report.
