Relating to instruments, all of us have our favorites as website positioning professionals. Ahrefs, Moz and Semrush goal to perform the identical issues at a excessive stage, however you’d be hard-pressed to search out an website positioning skilled who doesn’t have sturdy opinions on every software’s capability to take action.
Any seasoned website positioning 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 website positioning staff not too long ago put our opinions to the take a look at and biases to the facet to match the key phrase dimension of Google Search Console (GSC), Ahrefs, Semrush and Moz for the purchasers we handle.
When you can learn extra within the Methodology and Caveats and issues sections under, the nod to this knowledge not being definitive within the title is that it isn’t. The information was solely pulled for 51 domains, all of which reside within the pharmaceutical area. 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 unbelievable examine about key phrases hidden in Google Search Console. I encourage you to learn it, however the gist is whereas the quantity diverse drastically by website, virtually half of the general clicks have been attributed to hidden phrases.
On condition 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 top consumer.
However right here’s the fact. GSC nonetheless is perhaps the most effective we’ve relating to key phrase visibility dimension.
Among the many three, Ahrefs had probably the most key phrases for 98% of internet sites
Relative key phrase rating dimension 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 dimension for every of the 51 websites in our knowledge warehouse. I’ll be sincere; I used to be shocked on the consistency within the outcomes.
Ahrefs almost had a clear sweep of first-place finishes, with Semrush and Moz regularly 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 almost 5 occasions the quantity of rating key phrases for our purchasers as Moz. That’s an unimaginable disparity!
You is perhaps questioning, if Ahrefs has such a dominant lead on Semrush and Moz, why not simply use Ahrefs?
As sturdy as Ahrefs was, it missed 87% of key phrases
Second chart: The overall rating key phrases in Ahrefs in comparison with the overall 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 have been within the Ahrefs basket, we might be lacking out on a consequential quantity of key phrase knowledge.
Even for those who take away Google Search Console, Ahrefs nonetheless didn’t comprise 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 have been unique to Moz
Second chart: Whole rating key phrases unique to at least one supply evaluating Ahrefs, Moz and Semrush for 51 domains in Could 2022.
When trying on the chart on the proper, lacking out on 13% of whole key phrases is difficult to disregard.
Moz’s unique numbers dropped drastically when GSC was added to the combination 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 proportion 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 take a look at the alternative finish of the spectrum. As a substitute of exclusivity, the place was there full protection? If we drew a random key phrase out of a hat, how possible would it not be present in every of the 4 sources we analyzed?
Fewer than 1% of key phrases have been present in all 4 sources
A staggering quantity of key phrases in our dataset have been solely present in one supply. Conversely, only a choose few have been represented in all 4 sources.
The key phrase counts elevated modestly from 0.4% to 2.6% when shifting from 4 sources to 3. Even two sources didn’t cowl 10% of the overall key phrases.

Methodology
Information assortment
- Google Search Console: Unfiltered, query-level search knowledge was saved in our knowledge warehouse through Google Search Console’s API every day from Could 1 to Could 31 for 51 shopper domains. Key phrases have been deduplicated by area and aggregated right into a month-to-month whole.
- Semrush: One reside API name through Semrush’s Area Natural Search Key phrases report was saved in our knowledge warehouse in Could for 51 shopper domains. The U.S. was the designated area.
- Moz: Natural search key phrase rankings have 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 have 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 view 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 price 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 dimension comparisons of those instruments.
So, why publish the outcomes? As additionally touched on in the important thing takeaways part under, past the info being attention-grabbing and probably sparking useful dialogue, I needed 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 may have been a part of this examine to make it extra complete. If any reps from these instruments are studying this, we might be taken with evaluating your software to the remaining subsequent time round. Hit me up!
Supply comparability
With Ahrefs, Moz and Semrush, these have been one-time knowledge pulls inside the month of Could. Nonetheless, with Google Search Console, 31 separate API calls have been made. This will likely 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 price, I do not consider it will have impacted any overarching traits or takeaways.
Moreover, Google Search Console knowledge included cell 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 might change any of the traits 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 might be extra frightened if Moz missed a 25,000 MSV key phrase than a 25 MSV key phrase.
The following time this evaluation is run, we plan on incorporating quantity. Nonetheless, we’ll have to create logic round tips on how to finest embody GSC impressions as an MSV proxy, in addition to tips on how 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 contemporary. In different phrases, if we pulled GSC knowledge from Could, these key phrases have been undoubtedly seen in Could (even when just for a second).
Nonetheless, it is doable the opposite sources contained key phrases with no refreshed rankings pull since earlier than Could. If any of those instruments had disproportionately stale knowledge, it may have altered the outcomes.
Key takeaways
1. Problem your assumptions
Earlier than revealing the outcomes to my staff, I requested them to rank the 4 sources so as of key phrase protection primarily based on their very own intestine feeling. Round 10 folks guessed, together with me, however not one in every of us was right!
Semrush was routinely ranked decrease than we predicted, and GSC was not given almost sufficient credit score. Nonetheless, with GSC, that is extra possible because 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 slightly an excessive amount of, and this goes far past website positioning instruments. As entrepreneurs, we should always regularly strain take a look at our positions and be keen to vary our minds.
2. Use the GSC API
When pulling knowledge straight from Google Search Console’s consumer interface, you’re restricted to 1,000 rows of knowledge. If we had merely downloaded knowledge 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 knowledge by a substantial margin.
3. Use all of the instruments
Admittedly, this takeaway is a little bit of a contradiction coming from me. As said within the part above, we do not even use all the instruments, nor will we plan to. Nonetheless, I’ve constantly advocated for not utilizing only one website positioning software.
My precise recommendation is that this: put money into one-month subscriptions and/or free trials to gauge the relative efficiency in your particular class. From there, you may select the most effective software(s) for you primarily based in your explicit verticals, funds and targets. Our pharmaceutical shopper advertisements usually say, “Outcomes might fluctuate,” and the identical is true with this. Take the additional time to see what’s finest for you.
Additionally, when testing out instruments on your particular {industry} and desires, do not simply take a look at key phrase sizes. Measurement, accuracy, consumer expertise, buyer assist, expertise integrations and a lot extra will also be thought of.
4. Repeat and enhance your exams
Our first official take a look at is completed, however we do not plan on calling it quits. Semrush not too long ago went public. Moz was acquired simply over a yr in the past. Ahrefs launched a search engine.
That is an arms race, and if we do not refresh these outcomes periodically, we may very well be making selections on outdated and inaccurate knowledge.
