Search quantity might be probably the most often used metric in website positioning. It helps us gauge the recognition of varied key phrases and predict the search visitors we might get from rating for them.
However all too typically, inexperienced SEOs take the key phrase search quantity metric at its face worth, which ends up in poor advertising and marketing choices and waste of invaluable enterprise assets.
On this submit, we’re going to take a more in-depth have a look at the search quantity metric, clarify what it’s, the place it comes from, and the way it might typically lead you astray.
What’s key phrase search quantity?
Key phrase search quantity is an website positioning metric that tells you what number of instances monthly, on common, a sure key phrase is looked for in a particular location. Most of the time, search quantity refers back to the variety of searches in Google, however this metric may check with different search engines like google too.
One necessary distinction to level out is that search quantity displays the variety of precise searches of a key phrase quite than the variety of distinctive folks trying to find it.
Thus, if a key phrase has a month-to-month search quantity of 100, these searches might have been carried out by 100 totally different folks, or it might have been simply 10 folks making 10 searches every.
That small clarification is barely the tip of the iceberg of all of the issues that individuals typically get fallacious when analyzing the search quantity of a key phrase.
So let’s focus on 5 extra issues it’s good to know in an effort to make higher use of this metric.
1. Search quantity numbers are annual averages
Most website positioning instruments report search quantity as an annual common.
It’s not an enormous deal for search queries which have a comparatively constant search demand all year long. However it may be fairly deceptive for seasonal search queries or scorching tendencies.
Let’s evaluate the search quantity tendencies of the next two key phrases: “content material advertising and marketing” and “NFT.”

The key phrase “content material advertising and marketing” has been hovering between 12k and 17k searches a month in the midst of the 12 months. So its annual common of 16k is an affordable prediction of the search quantity that it’s prone to get within the months to come.

It’s a wholly totally different story for the key phrase “NFT,” although. In the middle of one 12 months, it went from virtually nothing to a whopping 2.3 million searches in March. Then it dropped to 374k in June and went as much as 952k in August.
In different phrases, it’s fairly onerous to foretell how its search quantity goes to fluctuate within the coming months and the place it’ll ultimately settle as soon as the craze over NFTs subsides.
What I need to illustrate with these two examples is that search volumes could be fairly unstable. And the 12-month common quantity that website positioning instruments report might not completely match the month-to-month search quantity of that key phrase by the point you rank for it.
2. Not all searches end in clicks
The truth that folks seek for one thing doesn’t essentially imply they’re going to click on on any of the search outcomes.
In reality, Google’s aim is to fulfill its customers proper there after which with out having them “waste time” clicking on any of the search outcomes. In keeping with a current examine, two-thirds of Google searches in 2020 ended and not using a click on.
Two-thirds of Google searches in 2020 ended and not using a click on.
For instance, the key phrase “elon musk age” will get 37k searches monthly (on common). However the variety of clicks on the search outcomes (in accordance with Ahrefs) is simply 6.3k.

That occurs as a result of Google offers an on the spot reply to that query, dissuading customers from clicking on any of the search outcomes:

So if a search question has a big search quantity, it doesn’t essentially imply that it’s going to convey you a lot of search visitors. Google might merely show the reply proper in its search outcomes.
3. Advertisers might steal your clicks
There’s one different factor which will steal these treasured clicks away from you: Google Advertisements.
As of immediately, Google shows as much as 4 paid search listings above the natural search outcomes. And in the event you hint the visible historical past of those paid placements, it turns into painfully apparent Google is attempting to make these advertisements practically indistinguishable from the natural search outcomes.
It additionally tends to decorate these advertisements with pictures and sitelinks to maximise the actual property they occupy and push the natural search outcomes additional down beneath.
In different phrases, rating on the prime for some widespread key phrase not ensures that you just’re going to get a lot of clicks from it.
Even in the event you examine the search outcomes for the key phrase you need to rank for and there aren’t any advertisements there, there’s no assure advertisements gained’t seem sooner or later. In reality, by rating on the prime for a key phrase, you’re pushing the pages of your opponents down beneath and leaving them with out search visitors; this may increasingly very properly provoke them to start out working advertisements.
4. Search volumes aren’t very correct
Google Key phrase Planner is broadly thought to be the very best supply of key phrase search quantity knowledge, because it comes immediately from Google itself. And it’s not a secret the overwhelming majority of website positioning instruments pull their key phrase search volumes from GKP.
However how correct are the search quantity numbers in GKP?
Effectively, there’s one supply of knowledge that’s universally deemed the “single supply of reality” in the case of search volumes: Google Search Console.
In case your web site persistently ranks on the prime of Google for a sure key phrase, the variety of “impressions” your web page will get for that key phrase shall be its precise search quantity.
Which means we will simply examine the accuracy of search volumes in GKP if we evaluate the search volumes with the precise impressions of the identical key phrases from GSC.
And that’s precisely what we did in our current experiment.

It turned out that the search volumes in GKP have been “roughly correct” in simply 45% of circumstances. In the remainder of the circumstances, GKP search volumes deviated from GSC impressions by a pretty big margin.
In different phrases, it’s fairly a stretch to name the search volumes in GKP “correct.” And we will’t even criticize GKP for this, as it’s a instrument for advertisers, not SEOs.
GKP tends to mix search queries with comparable that means collectively in a single group with out an choice to see a definite search quantity for every of these queries. That is fairly useful for advertisers however could be a actual headache for SEOs.
For instance, the next six key phrases will all be blended into one:
- computer video games free obtain
- free computer video games obtain
- free video games obtain for computer
- obtain free video games for computer
- free computer recreation downloads
- obtain computer video games free
- free video games to obtain for computer

And most website positioning instruments will mimic this habits as a result of they (allegedly) take their search volumes from GKP. So they are going to show the identical search quantity for every of those key phrase variations.
However right here at Ahrefs, we combine just a few different knowledge sources into our search quantity estimates (together with just a few years of historic clickstream knowledge), which permits us to “un-group” lots of such key phrase clusters and show a definite search quantity for every particular person key phrase:

This un-grouping makes Ahrefs’ search volumes a bit extra correct than these of GKP. And but our search volumes are nonetheless simply estimations quite than precise values that lots of our customers will like to see.
5. Greater key phrase search quantity ≠ extra visitors
The first use case of the key phrase search quantity metric in website positioning is to estimate the potential natural search visitors that your web page might get if it ranks for the key phrase, proper?
Effectively, let’s have a look at the next two key phrases:

If we evaluate their World (i.e., worldwide) search quantity, the key phrase “native website positioning” appears to be 27 instances extra widespread than the key phrase “submit web site to search engines like google.”
So does this imply that the #1 rating web page for “native website positioning” ought to get vastly extra search visitors than the #1 rating web page for “submit web site to search engines like google?”
Let’s examine that in Ahrefs’ Website Explorer:


It seems our assumption is totally fallacious. The highest-ranking web page for a 27 instances much less widespread key phrase appears to be getting two instances extra search visitors.
How come?
Effectively, this occurs as a result of pages don’t simply rank for a single key phrase. Should you look attentively on the two screenshots above, you’ll see that the top-ranking web page for “native website positioning” is rating in Google for 311 key phrases (search for the “Natural key phrases” tile), with eight of them rating within the prime 3 positions.
As for the #1 web page for “submit web site to search engines like google,” it ranks in Google for a complete of 1,400 key phrases, with 201 of them rating within the prime 3 positions.
Listed here are a few of these key phrases:

No matter search question you keep in mind, totally different folks will phrase it in another way. However Google is wise sufficient to grasp that each one these individuals are principally searching for the identical factor. It, subsequently, ranks the identical web page for all these search question variations.
We studied this “phenomenon” again within the day, and it turned out the typical top-ranking web page would additionally rank for a couple of thousand comparable key phrases.
This implies that you could’t blindly depend on the search quantity of particular person key phrases when estimating their search visitors potential. What it’s good to do as an alternative is study the top-ranking pages and see how a lot search visitors they get in whole from all of the key phrases they rank for.
Right here at Ahrefs, we acquired so enamored with this idea that we now have created a singular metric referred to as Site visitors potential:

For any key phrase that you just see in Key phrases Explorer, we pull the top-ranking web page and search for how a lot whole search visitors it will get from all of the key phrase variations that it ranks for in Google. That worth turns into the Site visitors potential of that key phrase.
Right here in Ahrefs’ content material advertising and marketing crew, we’ve been doing that manually for fairly just a few years, and it has helped us quite a bit in choosing the proper subjects to focus on. However now this metric is lastly added to Key phrases Explorer for everybody to use.
Ultimate ideas
So these are the 5 most important issues that rookie SEOs typically overlook once they take care of the key phrase search quantity metric.
Now that you just’re armed with this information, I’m positive you’ll not deal with the search quantity metric at its face worth, which ought to vastly enhance the standard of your website positioning choices.
And there’s one very last thing I need to point out. It appears a bit too apparent to place it within the physique of this submit, however it’ll really feel sort of incomplete with out it:
By no means choose key phrases based mostly on their search quantity alone.
There’s a lot extra to key phrase analysis than merely searching for key phrases with the largest search quantity.
Listed here are another questions to contemplate:
- Would this key phrase convey worth to my enterprise?
- Would this key phrase end in any gross sales?
- Would I be capable of beat the top-ranking pages for this key phrase?
- What would it not take to rank for this key phrase?
All the time maintain these questions in thoughts when selecting what key phrases to go for.
