Do we succeed at it? I’ll leave that for you to judge.
But one thing I know for sure — Ahrefs team is extremely competitive and we are never scared to go the extra mile where others would prefer to skive. For instance we update our hardware every 10–14 months (we’re soon moving to Xeon E5V4 CPUs and 4TB SSDs) for no particular reason other than to make sure that we’re using the world’s best technology and operating at the highest speeds possible.
So after looking at the usage statistics of our Keywords Explorer tool and realizing that it is was one of the least used tools in Ahrefs, we were immediately challenged to turn things around.
We knew that adding a few cool features here and there wouldn’t really make a difference. The only option was to start from scratch and take a shot at creating the very best keyword research tool in the industry.
So without further ado, I’d like to present you Keywords Explorer 2.0 — our brand new (and extremely powerful) keyword research tool.
(And the whole Ahrefs team is now holding their breath waiting for your assessment of our work.)
[TL;DR] What makes Keywords Explorer 2.0 special
This overview turned out to be pretty long and detailed. So just in case you’re in a hurry here’s a quick TL;DR.
11.6 Billion keywords database — Keywords Explorer 2.0 is running on an absolutely monstrous database of ~11.6 billion keywords from 200+ countries. This database is updated with fresh data every single month. To the best of my knowledge no other tool will match our size as of today. [Read more]
Accurate “Search Volume” (Local & Global) — we’re processing very large amounts of clickstream data, which allows us to calculate much more accurate search volumes than those in Google Keyword Planner (especially if you’re on a low spending Adwords account). [Read more]
“Clicks” metric — searches in Google don’t always result in clicks on any of the search results. For example people search a lot for “donald trump age”, but they don’t click on any results because they see the answer right away.
Thanks to clickstream data we can see if people are actually clicking on any of the search results after performing a search. Which means we can show you quite accurately which percentage of searches result in clicks. [Read more]
A lot of our beta testers called this new metric a “game changer”:
Tons of keyword ideas — one of the main things that our customers loved about the old version of Keywords Explorer was the list of keyword ideas that effectively dwarfed any other tool:
Well, the 2.0 version of the tool with its 11.6 Billion keyword database will give you even more. [Read more]
Parent topic — for any keyword that you put into Keywords Explorer 2.0 we will check the #1 ranking page and determine the best keyword that this page ranks for.
This little trick gives you an idea if your keyword belongs to a broader topic and if you can rank for your keyword while actually optimising your page for this broader topic. [Read more]
Keyword difficulty — our KD score has already won the first prize among the existing solutions. So to be honest we didn’t change anything about it in “2.0” version of Keywords Explorer. But still there are quite a few things you might want to know about it. [Read more]
SERP overview & Positions History — our Keyword Difficulty score is quite good, but it will never beat an opinion of an experienced SEO specialist. For that reason we have designed an all new “SERP overview” report, which brings all the core SEO metrics together to help you make educated decisions about the actual difficulty of a given SERP. [Read more]
And for a subset of the best keywords in our database we’ll also show you a cool graph with ranking history of top5 search results, which gives some extra insights about the toughness of a SERP. [Read more]
Keyword Lists — a very simple, but a highly requested feature. Once you come across some juicy keyword ideas, you can now save them into a list for future reference. This can be a huge time saver if you’re doing keyword research for multiple projects. [Read more]
That’s it for a quick TL;DR.
And now onto a much more detailed review of Keywords Explorer 2.0.
Where did we get so many new keywords?
We have processed huge amounts of clickstream data for the past 12 months (i.e. we analyzed what millions of people around the globe were searching for in Google), so all these new keywords in our database are very fresh and trendy.
What is “clickstream data”?
There’s no point in me explain it here, since there’s this great article by Russ Jones which does it perfectly: “Google’s War on Data and the Clickstream Revolution”.
200+ countries supported
Not only have we massively increased our database in size, we now also support a load of new countries.
Here’s a chart showing you the current top ten countries in our database:
So if you were looking to perform keyword research in any language other than English, please give our tool a try and let us know how it goes.
Monthly database updates
In the teaser video for Keywords Explorer 2.0 we promised you “2.8 Billion keywords”. But at the time of writing this post we’re at 11.6 Billion already.
And there’s a chance that our keyword database will get even bigger, because we’re now processing fresh clickstream data every month.
This allows us to regularly import new keywords that were never seen before and build fancy looking trends for the keywords that we already have in our database.
For example, here’s our search volume trend for “iPhone 7”:
If you enter some keyword into Keywords Explorer 2.0 and we return “No data” — in 99% of cases that means that this keyword is simply not popular enough.
And in case this keyword is only starting to gain popularity. You’ll find it in our tool next month after we process fresh clickstream data.
Which means that (unless you setup a campaign and start running ads) you will now see six lousy ranges instead of the accurate search volumes that you used to get.
These six ranges are: 1–100, 100–1K, 1K-10K, 10K-100K, 100K-1M, 1M+, and they make GKP almost useless for anyone who’s not looking to spend money on ads.
But that is only a half of the problem.
The other half is that GKP is now grouping keywords with similar meaning and showing identical volumes for them:
These two pieces of news came as an existential threat to every keyword research tool that relied on Google Keyword Planner for search volume data.
But luckily we have clickstream data, which helps to bring the search volume accuracy back.
Ahrefs’ Search Volume
The search volume data that we have collected from clickstream was paired with our existing volume data (from Google Keyword Planner) and after a few iterations we created a model that would give a very accurate search volume for almost any keyword there is.
Keywords Explorer 2.0 shows you both Local and Global search volume, with the figure being an average over the last 12 months.
Back to this very irritating issue with keyword grouping. Let’s try the following keywords in GKP:
- search engine optimization;
- seo optimization;
- define seo;
- search optimization.
They have grouped 5 keywords that I’ve entered into 3. And that is a “paid” account I’m using, not even a free one.
Now let’s put the same 5 keywords into Ahrefs:
As you can tell, we’re able to un-group these keywords and show you the real search volume for each of them.
This is our brand new metric that no other tool will show you as of today.
“Return Rate” is a relative number that gives you an idea of how often people perform the same search over the course of a month.
“1” means that people never search for that keyword again. But “2” doesn’t mean that they search for it two times per month on average. It just means that they search for it quite often.
Yes, it’s super confusing. But give me a chance to explain it with an example:
As you can see, people in the UK tend to search “queen age” only once and they hardly ever search for it again. That’s probably because they memorize the answer instantly.
But then you can see that they return to search for “brexit” quite often. Probably because the search results always contain some fresh news on that topic that are of high interest to them.
And finally, “manchester united” has the biggest return rate, which could be an indication that people in the UK follow football news almost religiously.
So again, RR 2.02 for “brexit” and RR 2.22 for “manchester united” doesn’t mean that people search for one of them 2.02 times on average and 2.22 times for the other.
But it gives you a general idea that people in the UK perform a search for “manchester united” a bit more often than a search for “brexit”.
I’m talking about this simple realization:
Here’s a great example that clearly illustrates what we mean by that:
As you can see, the keyword “chauffeur” has a huge search volume of 42,000, but that only results in 10,035 clicks.
People search for it, but don’t seem to click on the search results. Why?
There are two reasons for that:
- Many people put the word ”chauffeur” into Google just to check if the spelling is right (I do it all the time with some fancy words);
- Google gives you a Knowledge Card right at the top of the search results with a definition of the word “chauffeur”.
What else would you want to know when searching for the word “chauffeur” besides spelling and definition?
So there you have it. People don’t need to click on any of the search results to get what they wanted — hence the low number of clicks, while the volume is deceptively big.
Now let’s look at the other keyword — “wow chauffeur”.
“WoW” here refers to World of Warcraft. So it looks like people are looking for some information about the “chauffeur” character in World of Warcraft.
And once you look at the search results for this keyword, you’ll see that there’s no good information upfront. Which means that you have to click on something in order to learn about “wow chauffeur”.
This is why this keyword gets a high volume of clicks.
So if you compare these two keywords purely by their search volume, it may seem that there’s almost a 10x difference in traffic potential.
But when you compare the number of actual clicks on the search results, you’ll see that there’s only a 2x difference in traffic potential.
Sounds awesome? Read on!
Clicks Per Search (CPS)
Like I just said, the search results for “wow chauffeur” don’t contain any good information upfront, so you don’t know whether or not you’ll get what you’re looking for after clicking a certain search result.
And so you click a few of them.
That is why the CPS (Clicks Per Search) metric for “wow chauffeur” says “1.15”. It means that searchers on average tend to click on more than one search result when searching for this keyword:
And if you were wondering why the number of clicks for “wow chauffeur” is bigger than it’s actual search volume, the Clicks Per Search metric is the answer.
Knowing the CPS of a keyword is crucial for understanding the traffic potential of pages that rank below the #1 result. The higher the CPS — the more chances that you’ll get some nice traffic even at a slightly lower position like 4 or 5.
But organic results aren’t the only ones getting clicks.
Organic Clicks VS Paid Clicks
When you bid for some keyword, Google will show your ad at the very top of the search results, pushing down all the pages that rank for this keyword organically.
And since Google is now showing up to 4 ads, the organic results are about to go below the fold on my 15” screen:
What I’m trying to illustrate here is that these ads quite effectively steal clicks away from organic search results.
This is why experienced SEOs will always check the actual SERP for ads to determine if that keyword is worth ranking for.
And Keywords Explorer 2.0 can now show you what percentage of all clicks go to ads.
Let’s see on a real example how much value this metric brings to the table.
If we were only making decisions based on pure Search Volume — “iphone 7 cases” would clearly be a much better keyword to go for than “best iphone 7 cases”.
But let’s see how many clicks ads steal away from each of these keywords:
- “iphone 7 cases”: 25,353 * 22% = 5,577
- “best iphone 7 cases”: 7,773 * 2% = 155
Let me put all these numbers into a spreadsheet:
And this is how we went from a 5x difference in organic search traffic potential between these keywords to 2.6x difference.
Better understanding of searchers’ behaviour
We were super excited while playing with all these new metrics ourselves and we’re hoping that you’re going to love them too and adopt them in your keyword research.
And for those still puzzled by all this, here’s a simple illustration of the metrics that Keywords Explorer 2.0 shows you:
That is a very simplified model, as we’ve only started scratching the surface of the actual complexity of searchers’ behaviour.
But we already have quite a few ideas for new reports and metrics that will give you even better idea of how people search for your target keywords.
For the keyword “blogging”, the tool will give you over 35k different ideas:
And because you have Search Volume on all of them and cached Keyword Difficulty on the very best of them — you can use filters to quickly drill down this huge list of suggestions to a small one with only the very best.
Multiple seed keywords
After many years of using Google Keyword Planner tool SEOs got used to entering multiple “seed” keyword for generating a list of relevant keyword ideas.
We couldn’t allow ourselves to disrupt this use case, so in Keywords Explorer 2.0 we can use up to 10 seed keywords for generating keyword ideas for you.
Which means that if I add keywords “snorkeling” and “kitesurfing” to my initial seed keyword “blogging”, I’ll get almost 3x more keyword ideas:
Fun Fact: according to their search volumes, snorkeling is the most popular of these three activities.
3 keyword ideas reports
There are three reports you can choose from.
1. Matching terms
In this report, we show keyword ideas that contain your target keyword or phrase.
From here, you can toggle “All” to see all keyword ideas or “Questions to see keywords phrased as questions.
So, for example, if your seed keyword is “cats”, we’ll give you keywords like:
- why do cats purr;
- why do cats knead;
- how long are cats pregnant;
- when do cats stop growing.
You can also choose between two modes:
- Terms match. This mode shows you all keyword ideas that contain all the words from your query in any order. For example, if your seed keyword is “lose weight”, then “how much weight can you lose in a month” would appear here.
- Phrase match. This mode shows you all keyword ideas that contain your target keyword or phrase in the order it’s written. For example, if your seed keyword is “lose weight”, then “how to lose weight” would appear here.
You can mix and match them. For example, you can toggle “Questions” and choose between “Terms match” or “Phrase match” to see different keyword ideas.
2. Related terms
In this report, we show keyword ideas that are related to your seed keywords or phrases.
There are three options for you to choose from here:
- Also rank for. According to our study of three million search queries, the average #1 ranking page will also rank in the top10 for nearly 1,000 other relevant keywords. Turn the toggle “Also rank for” to see what these keywords are.
- Also talk about. See the keywords and phrases the top-ranking pages for your target keyword frequently mention. These keywords could be good sub-topics or sub-points to cover in your own content.
- All. Both reports combined.
For all three reports, you can choose to see keywords for the top 10 or top 100 ranking pages.
3. Search suggestions
In this report, we show ‘autocomplete’ suggestions for your target query and related terms.
While Google only shows a handful of suggestions, we show nearly all keyword ideas along with SEO metrics.
When researching organic search traffic of their competitors, these days SEOs look at the “Top Pages” report way more often than “Organic keywords” report.
The reason being that a single page can rank for hundreds of closely related keywords and bring in a ton of traffic from search.
Here’s a cool example that illustrates this “topics over keywords” concept:
On that screenshot above I’m looking at the “Top Pages” of Moz Blog and I see that one of their articles ranks for over 1K different keywords. The most popular among these keywords is “how to choose a domain name” so I consider it the main topic of this post.
So basically the idea of “topics over keywords” is that you don’t need to create an individual article to target each of these keywords. You can rank for all of them with a single post.
In Keywords Explorer 2.0 we tried to reverse-engineer this concept.
So if I take all these “other” keywords that article from Moz ranks for, and put them into Keywords Explorer 2.0, it will show me the “parent topic” that these keywords fall into:
We believe that this “Parent topic” feature is a huge thing for keyword research, because it can tell you how many pages you need to create in order to target all the keywords that you wish to rank for.In this release we didn’t change anything about our KD score. Mostly because we believe it is quite good as it is (which was also confirmed by third party tests).
I have already published a pretty detailed post about our Keyword Difficulty score and how to apply it in your keyword research, but I’m still going to re-hash some of the most important points here:
KD is based on backlink data
Ever since we first introduced our Keyword Difficulty score there has been a ton of dicussion about what factors we should or should not be taking into account when calculating it.
And the fun thing is — there’s no single opinion on how much each individual factor should influence keyword difficulty score. What seemed hyper important for some SEOs was secondary at best for others.
We also ran a study of 2 Million keyword searches to investigate how different on page SEO factors correlate with Google rankings. Here’s what we learned from it:
As you can tell from this graph, the correlation of backlink factors (both page-level and domain-level) massively outweighs the major on page SEO factors.
And this is how we settled with the decision to calculate our KD score based on backlinks only.
KD scale is not linear
As I was watching screencasts recorded by our beta testers I noticed that many of them tried to compare our KD score with what other tools were reporting.
You can’t compare Ahrefs KD score to what any other tool shows, because our scale is most likely very different from theirs:
As you can see from the image above, our scale is not linear and mostly consists of hard and super hard keywords.
So if some other tool gives you KD score of “40” and you read it as “Medium” difficulty, on Ahrefs’ scale “40” means “Hard”.
And because we only rely on backlinks when calculating KD score, our scale is super easy to understand:
KD 0 = 0 Ref. Domains
KD 10 = 10 Ref. Domains
KD 20 = 22
KD 30 = 36
KD 40 = 56
KD 50 = 84
KD 60 = 129
KD 70 = 202
KD 80 = 353
KD 90 = 756
Basically our KD score shows you the average number of referring domains that pages ranking on the front page of Google have. So the odds are, you’re going to need more or less the same number of websites linking to your page if you want to outrank your competition.
Plans to improve KD
We do believe that our KD score measures the difficulty of a keyword quite accurately compared to what other tools show.
But at the same time we do understand that there’s a massive room for improvement and we can make this score a lot better. Which we plan to do in one of the future updates of Keywords Explorer.
So if you happen to have any suggestions of which factors we should be taking into account (and how much influence they should have on resulting KD score) please email me and I’ll be happy to discuss it with you.
Nothing beats the experience (and intuition) of a professional SEO and all we can help with at this point is bring all the SEO metrics we have to the SERP:
This is how the front page of Google looks like for the keyword “Marvel“.
And as you can tell, Ahrefs Keywords Explorer gives you a ton of very useful data right away:
- How many organic results are there;
- How many different SERP features are there;
- What are the domain level and page level backlink metrics;
- What is the estimated organic traffic to each page;
- How many keywords each page ranks for;
- What is the top keyword each page ranks for;
- How many shares on Facebook and Google plus each page has.
There are many more things we could potentially show here, but we’ve saved them for future updates of the tool.
Well, because we closely monitor these keywords, we can also show you the positions history of pages that currently rank in top5. It looks like this:
This helps a lot in figuring out if the SERP is stable and very hard to penetrate or if Google is mixing pages all the time trying to figure out which combination serves searchers best.
For instance, on the above screenshot you see SERP position history for “keyword research”. Here’s another fun graph:
It’s the top 5 for the keyword “soccer”, and you can tell that the SERPs is generally unstable as pages keep entering and dropping out.To be honest I’m somewhat embarrassed that we didn’t have keyword lists in the very first release of Keywords Explorer, because this feature is so darn obvious.
But now we’ve fixed our mistake:
The keyword lists that you create will be available on the home screen of Keywords Explorer 2.0 and also in the left navigational panel within the tool.
Tell Us What You Think
As you can probably tell from this review alone, we worked super hard trying to impress you with this new tool.
It turned out to be so powerful and feature-rich that I struggled to keep this overview under 4000 words. In fact I had to omit quite a few cool things we have in this tool for the sake of keeping it short (I’m sure you’ll find them on your own).
So please play with Keywords Explorer 2.0 and tell us what you think about this new tool.
