With regards to instruments, all of us have our favorites as search engine optimisation professionals. Ahrefs, Moz and Semrush purpose to perform the identical issues at a excessive stage, however you’d be hard-pressed to seek out an search engine optimisation skilled who doesn’t have robust opinions on every software’s skill to take action.
Any seasoned search engine optimisation practitioner is aware of opinions alone can get you roughly so far as asking Google’s John Mueller about area authority (trace: not far).
Our search engine optimisation crew lately put our opinions to the check and biases to the aspect to match the key phrase measurement of Google Search Console (GSC), Ahrefs, Semrush and Moz for the shoppers we handle.
Whilst you can learn extra within the Methodology and Caveats and issues sections under, the nod to this information not being definitive within the title is that it isn’t. The info was solely pulled for 51 domains, all of which dwell within the pharmaceutical house. So, it’s a small, non-representative pattern. You’ve been warned.
GSC had over 36% extra key phrases than the opposite sources mixed
Patrick Stox from Ahrefs revealed a implausible research about key phrases hidden in Google Search Console. I encourage you to learn it, however the gist is whereas the quantity various significantly by website, nearly half of the general clicks had been attributed to hidden phrases.
Provided that Google Search Console hides decrease quantity key phrases, which make up the vast majority of search queries, this possible means considerably greater than half of the key phrases are obstructed to the tip consumer.
However right here’s the fact. GSC nonetheless could be the most effective now we have in terms of key phrase visibility measurement.
Among the many three, Ahrefs had probably the most key phrases for 98% of internet sites
Relative key phrase rating measurement by area
| Supply | 1st | 2nd | third |
| Ahrefs | 50 domains | 0 domains | 1 area |
| Semrush | 0 domains | 50 domains | 1 area |
| Moz | 1 area | 1 area | 49 domains |
In some ways, it’s unfair to match Ahrefs, Semrush and Moz to Google Search Console. GSC’s metrics and supposed use distinction fairly a bit from the opposite three instruments.
So, when eradicating GSC, we ranked the key phrase measurement for every of the 51 websites in our information warehouse. I’ll be trustworthy; I used to be shocked on the consistency within the outcomes.
Ahrefs practically had a clear sweep of first-place finishes, with Semrush and Moz frequently coming in second and third.
On common, Ahrefs had twice the rating key phrases as Semrush, which had over twice as many as Moz. Ahrefs had practically 5 instances the quantity of rating key phrases for our shoppers as Moz. That’s an unbelievable disparity!
You could be questioning, if Ahrefs has such a dominant lead on Semrush and Moz, why not simply use Ahrefs?
As robust as Ahrefs was, it missed 87% of key phrases
Second chart: The whole rating key phrases in Ahrefs in comparison with the full rating key phrases present in Moz and/or Semrush and never in Ahrefs for 51 domains in Could 2022.
First, the truth that Ahrefs is even capable of be in comparison with the opposite sources stacked collectively is highly effective. That is removed from a knock on it. Nonetheless, if all of our eggs had been within the Ahrefs basket, we’d be lacking out on a consequential quantity of key phrase information.
Even in the event you take away Google Search Console, Ahrefs nonetheless didn’t include 32% of key phrases.
On the identical time, not utilizing Moz (our smallest supply), leaves some blindspots.
When in comparison with Ahrefs and Semrush, 13% of key phrases had been unique to Moz
Second chart: Whole rating key phrases unique to 1 supply evaluating Ahrefs, Moz and Semrush for 51 domains in Could 2022.
When trying on the chart on the suitable, lacking out on 13% of complete key phrases is difficult to disregard.
Moz’s unique numbers dropped drastically when GSC was added to the combo with beneath 2% of key phrases. However as I’ve beforehand talked about, these instruments aren’t precisely equal in what they cowl.
Semrush’s exclusivity share jumped to 24% when in comparison with Ahrefs and Moz, but it surely was additionally sitting at beneath 2% when GSC was included.
Let’s have a look at the alternative finish of the spectrum. As an alternative of exclusivity, the place was there full protection? If we drew a random key phrase out of a hat, how possible wouldn’t it be present in every of the 4 sources we analyzed?
Fewer than 1% of key phrases had been present in all 4 sources
A staggering quantity of key phrases in our dataset had been solely present in one supply. Conversely, only a choose few had been represented in all 4 sources.
The key phrase counts elevated modestly from 0.4% to 2.6% when transferring from 4 sources to 3. Even two sources didn’t cowl 10% of the full key phrases.

Methodology
Information assortment
- Google Search Console: Unfiltered, query-level search information was saved in our information warehouse by way of Google Search Console’s API every day from Could 1 to Could 31 for 51 shopper domains. Key phrases had been deduplicated by area and aggregated right into a month-to-month complete.
- Semrush: One dwell API name by way of Semrush’s Area Natural Search Key phrases report was saved in our information warehouse in Could for 51 shopper domains. The U.S. was the designated area.
- Moz: Natural search key phrase rankings had been manually exported from the entrance finish of Moz’s Key phrase Explorer utilizing the default settings in Could for 51 shopper domains.
- Ahrefs: Natural search key phrase rankings had been manually exported from the entrance finish of Ahrefs’ Key phrases Explorer utilizing the default settings in Could for 51 shopper domains.
Processing and evaluation
A question-source matrix was created with a purpose to decide the place there was overlap and exclusivity amongst Ahrefs, Google Search Console, Moz and Semrush per shopper area and in mixture.
Caveats and issues
Information pattern
I discussed this within the introduction, but it surely’s value repeating. Our evaluation featured each a small and industry-specific pattern of area rankings. You shouldn’t draw any conclusions round general relative key phrase measurement comparisons of those instruments.
So, why publish the outcomes? As additionally touched on in the important thing takeaways part under, past the info being fascinating and doubtlessly sparking helpful dialogue, I wished to emphasize the worth of analyzing these instruments beneath the lens of your {industry}.
Supply availability
Ahrefs, Google Search Console, Moz and Semrush will not be the one merchandise with distinctive key phrase visibility datasets. Serpstat, seoClarity, Brightedge’s Information Dice and different instruments might have been a part of this research to make it extra complete. If any reps from these instruments are studying this, we’d be involved in evaluating your software to the remaining subsequent time round. Hit me up!
Supply comparability
With Ahrefs, Moz and Semrush, these had been one-time information pulls throughout the month of Could. Nonetheless, with Google Search Console, 31 separate API calls had been made. This will have inflated GSC’s numbers a bit.
Had we pulled rankings every day in Could for the opposite instruments, extra distinctive key phrases would have been added both from shifting area rankings or key phrase database updates. For what it is value, I do not imagine it could have impacted any overarching tendencies or takeaways.
Moreover, Google Search Console information included cellular and desktop key phrases from all international locations, whereas we solely included U.S. desktop rankings from the opposite sources. This once more would inflate GSC’s numbers, however not more likely to a level that will change any of the tendencies in a significant approach.
Key phrase quantity exclusion
Key phrase quantity was not included on this train, which limits its potential worth. With all else being equal, I would be extra apprehensive if Moz missed a 25,000 MSV key phrase than a 25 MSV key phrase.
The subsequent time this evaluation is run, we plan on incorporating quantity. Nonetheless, we’ll have to create logic round easy methods to finest embrace GSC impressions as an MSV proxy, in addition to easy methods to calculate the amount for key phrases present in a number of instruments.
Information freshness
Information freshness was not thought of on this evaluation. As a result of approach its metrics work, Google Search Console is inherently recent. In different phrases, if we pulled GSC information from Could, these key phrases had been undoubtedly seen in Could (even when just for a second).
Nonetheless, it is attainable the opposite sources contained key phrases with no refreshed rankings pull since earlier than Could. If any of those instruments had disproportionately stale information, it might have altered the outcomes.
Key takeaways
1. Problem your assumptions
Earlier than revealing the outcomes to my crew, I requested them to rank the 4 sources so as of key phrase protection based mostly on their very own intestine feeling. Round 10 folks guessed, together with me, however not certainly one of us was right!
Semrush was routinely ranked decrease than we predicted, and GSC was not given practically sufficient credit score. Nonetheless, with GSC, that is extra possible as a consequence of them getting used to pulling the info from the front-end consumer interface.
All of us may be responsible of trusting our intestine emotions and hunches somewhat an excessive amount of, and this goes far past search engine optimisation instruments. As entrepreneurs, we should always frequently strain check our positions and be prepared to vary our minds.
2. Use the GSC API
When pulling information immediately from Google Search Console’s consumer interface, you’re restricted to 1,000 rows of information. If we had merely downloaded information from GSC with the date vary of Could 1 to Could 31, this software would now not have been main the pack (removed from it).
Querying GSC from the API nonetheless has its limitations, but it surely will increase the quantity of obtainable information by a substantial margin.
3. Use all of the instruments
Admittedly, this takeaway is a little bit of a contradiction coming from me. As acknowledged within the part above, we do not even use all the instruments, nor can we plan to. Nonetheless, I’ve persistently advocated for not utilizing only one search engine optimisation software.
My precise recommendation is that this: spend money on one-month subscriptions and/or free trials to gauge the relative efficiency in your particular class. From there, you’ll be able to select the most effective software(s) for you based mostly in your explicit verticals, price range and targets. Our pharmaceutical shopper adverts typically say, “Outcomes might range,” and the identical is true with this. Take the additional time to see what’s finest for you.
Additionally, when testing out instruments in your particular {industry} and wishes, do not simply have a look at key phrase sizes. Measurement, accuracy, consumer expertise, buyer help, know-how integrations and a lot extra will also be thought of.
4. Repeat and enhance your assessments
Our first official check is finished, however we do not plan on calling it quits. Semrush lately went public. Moz was acquired simply over a 12 months in the past. Ahrefs launched a search engine.
That is an arms race, and if we do not refresh these outcomes periodically, we could possibly be making selections on outdated and inaccurate information.
