Ubersuggest vs Ahrefs

If you’re unsure about using Ubersuggest or Ahrefs, then this guide is for you.

Both offer free and paid features.

Watch the 20-minute video explaining the key features and benefits of each.

What is Ubersuggest?

Ubersuggest is a free and low-cost SEO keyword research tool from Neil Patel providing keyword ideas, competitor website traffic estimates, keyword position tracking, backlink data and a site audit tool.

Is Ubersuggest free or how much does Ubersuggest cost ?

You have free, limited use of Ubersuggest; there’s a 7-day free trial then a monthly payment of £29, £49 or £99 a month.

What is Ahrefs?

In a poll of 4209 SEO experts, 39.5% voted Ahrefs as their primary, paid SEO tool of choice, making Ahrefs the most used keyword research, backlink research, content research, competitor research and rank tracking tool. 

How much does Ahrefs cost?

Ahrefs have 4 paid-for plans; $99, $179, $399 and $999 a month with a yearly discount on each plan. The plans are ideal for small business users, small web agencies with 1 to 3 users or larger SEO agencies with 5 or more users.

First up, I compared the traffic of the top page.

Top Page Traffic Comparison

This screenshot compares the top page traffic of my website from Ubersuggest and Ahrefs.

When I compared my top page with both keyword research tools, they produced fairly similar results.

Estimated traffic

Ahrefs estimates I get more traffic whilst Ubersuggest tells me that my page ranks for more keywords.

Bear in mind both tools are estimates.

In reality, my pages get over 1,000 organic visits per month and rank for 2572 keywords.

But the traffic estimates for the top-ranking keyword, business ideas uk, varies massively.

Search volume and position

Search volume and keyword position are almost identical.

Good to know.

How to calculate keyword difficulty with Ubersuggest and Ahrefs

Ahrefs keyword difficulty is calculated as follows :

“It’s calculated by taking a weighted average of the number of linking domains to the current top-ranking pages.

The result is then plotted on a logarithmic scale from 0 to 100 (low difficulty to high).”

So if keyword difficulty is 5, then you need around 5 links to your page to rank in the top 10 results.

Depending on the client I’m working with, I’ll generally avoid keywords with a KD score above 30.

Provided your content serves the user intent.

Ubersuggest refers to keyword difficulty as SEO difficulty.

To quote them, estimated competition in organic search; the higher the number, the more competitive.

• Low competition is shown in light green; 0 to 35
• Medium competition is shown in light yellow; 36 to 70
• High competition is shown in pink; 71 to 100

However, they don’t tell you how they calculate keyword difficulty.

With Ubersuggest, I will manually view their report that shows links to the top pages then make the best judgement on keyword difficulty.

i.e.:

if all the top pages have high domain scores and have a high number of links to their pages, then it’s too difficult to rank, and I’ll avoid trying.

However, if there are a few top-ranking pages with no or just 1 or 2 links and the domain scores aren’t all in their 90’s then I’ll consider this an opportunity.

Links to page

I have 3 links to my page; Ubersuggest doesn’t report page backlinks.

So as a measurement of difficulty, it shows you can rank for harder keywords with a smaller number of links than Ahrefs predicted.

If I only needed a tool to estimate top page traffic, I’d say Ubersuggest is a useful tool to have at your disposal.

Top Traffic Page Comparison	Ubersuggest	Ahrefs
Traffic	336	428
Backlinks	N/A	3
No. of keywords ranked for	353	312
Keyword comparison	business ideas uk	business ideas uk
Keyword search volume	2900	3100
Keyword position	9	9
Estimated traffic for keyword	43	150
Keyword difficulty of keyword	29	20
CPC of top keyword	£0.86	$1.90

Keyword Research Tool Comparison

Next, I wanted to compare their keyword research tool.

I used the same seed keyword as above; business ideas for Google UK searches.

I have highlighted the main keyword research data from both tools for my seed keyword.

The search volume varies considerably.

In terms of difficulty, Ubersuggest state this keyword is easy but Ahrefs say it’s medium difficulty, needing 22 links to the page to rank on page 1.

I’d say this keyword and topic is hard to rank for.

Ahrefs deliver additional data about this seed keyword.

• Ahrefs tell you clicks to the top pages for this keyword.
• They tell you what percentage of clicks come from organic search results.
• They tell you the percentage of times that result was clicked.
• And Ahrefs tell you the RR, the return rate, how often people come back and made that search again the same month.

This data is important to know.

You could, for example, pick a keyword with high search volume and low difficulty.

Then it turns out hardly anyone clicks the results, and those that do only click from paid results.

Basing your strategy on half the information could set you up for disappointment and failure.

So the feature comparison between the tools is beginning to widen.

Business ideas (UK)	Ubersuggest	Ahrefs
Search Volume	18100	12000
Difficulty	29	20
Cost per click	£0.86	$1.90
Clicks	N/A	11000
Return Rate	N/A	1.31
Percentage of clicks	N/A	56%
Percentage of organic clicks	N/A	90%

Now, what about the number of keyword ideas each tool can generate?

Keyword Ideas Comparison

Next, I wanted to discover how many keyword ideas related to the seed keyword each tool delivered.

Each tool shows 2 types of keyword ideas, the same as keywords and all keyword ideas.

Same as keyword ideas

Same as or same term keywords are those keywords that contain the same phrase.

So with Ubersuggest, I’m shown 146 same as keyword suggestions compared to 17673 same as keywords from Ahrefs.

That’s a massive difference.

Just look at the screenshot above to see the ideas that Ahrefs deliver.

It appears that Ubersuggest is mainly delivering longer tail variations of the seed keyword and not looking for words before the seed terms.

All keyword ideas

Next, I looked at all keyword ideas; maybe some of the keywords you need from Ubersuggest are stored under the related keywords tab.

Business ideas (UK)	Ubersuggest	Ahrefs
Same as keywords	146	17673
All related keywords	688	20740

Yes, you need to look under related keywords in Ubersuggest to find some of the keyword ideas Ahrefs show as same as keywords.

But when I compared all the keyword ideas for Ubersuggest and Ahrefs, there’s still a vast gap between 688 and 20,740 keywords.

So when it comes to keywords ideas, as Gary V would say, Ahrefs is crushing it.

Keyword Filtering Comparison

Another essential part of keyword research is the ability to filter keywords by words, phrases or difficulty.

Filtering keywords is useful when understanding the users’ intent.

For example, if we take this post, it’s called Ubersuggest versus Ahrefs: a keyword research comparison.

I know most of my target market use free research tools like Google Planner and Ubersuggest.

I know I can deliver better rankings and traffic results for their clients by using paid research tools than free tool.

There are 4 types of searches.

• Informational – how to, what is
• Navigational – branded search eg: Google Adwords login, pubs near me, car repair shop phone number
• Commercial Investigation – best, versus, compare, alternative, this product for that person
• Transactional – buy, order, get, download, cheapest

That’s where keyword filtering is so critical.

Keyword modifier filtering

In this exercise, I chose to filter the seed keyword, business ideas, by queries containing “online”, “small”, “how”, “what”, and “best” to discover how many keywords each tool delivered.

Then I chose to filter by keyword difficulty to discover how many keywords were returned.

Filter seed keyword with “online”

Here’s a screenshot comparing the number of keywords when you filter the seed keyword by the word “online”.

Ubersuggest have 2 keyword ideas that contain “online”, whereas Ahrefs have 709 keyword ideas.

Filter seed keyword with “small”

Here’s a screenshot comparing the number of keywords when you filter the seed keyword by the word “small”.

Ubersuggest have 1 keyword idea that contains “small”, where Ahrefs have 1932 keywords.

Filter seed keyword with “how”

Here’s a screenshot comparing the number of keywords when you filter the seed keyword by the word “how”.

Ubersuggest doesn’t have any keyword ideas that include “how”, whereas Ahrefs have 82 keywords.

Whilst the search volume of these 82 keywords is really small, 50 searches a month, finding small volume keywords and ranking them on page 1 can still deliver good traffic for a brand new website.

Filter seed keyword with “what”

Here’s a screenshot comparing the number of keywords when you filter the seed keyword by the word “what”.

Again, Ubersuggest fails to deliver any keyword ideas for my seed keyword that includes “what”.

However, Ahrefs gives me 57 long tail, small volume keyword ideas.

Filter seed keyword with “best”

Here’s a screenshot comparing the number of keywords when you filter the seed keyword by the word “best”.

Ubersuggest doesn’t deliver any keyword ideas, whereas Ahrefs give 960 keywords ideas.

Now let’s filter by keyword difficulty.

Keyword difficulty filtering

Filtering keyword ideas by difficulty is a popular strategy of many web professionals.

For newer or less authoritative websites, we tend to avoid the hard to rank topics and keywords.

Filter seed keyword by medium difficulty

Here’s a screenshot comparing the number of keywords when you filter the keyword difficulty from 0-30.

In this example, Ubersuggest is better at delivering keyword ideas when you filter your seed keyword by difficulty than a word.

As you can see from the above 142 keyword ideas from Ubersuggest and 202 from Ahrefs.

Filter seed keyword by low difficulty

Now, here’s a screenshot comparing the number of keywords when you filter the keyword difficulty from 0-10.

Ahrefs have twice as many keyword ideas when you filter by very low keyword difficulty.

Comparing keyword filtering

So to summarise, here’s a tool comparison when applying 7 different keyword modifier filters.

Business ideas (UK)	Ubersuggest	Ahrefs
online	2	709
small	1	1932
how	0	82
what	0	57
best	0	960
0-30 difficulty	142	202
0-10 difficulty	53	107

SERPS Comparison

The next comparison was how each keyword research tool estimates the traffic to the top 10 pages.

In this day and age of featured snippets and Google scraping questions and answers, we must know the keywords and topics we research can realistically earn traffic.

Each tool delivers different pages in different positions and provides other page traffic estimates.

From the table and screenshot below, it appears Ubersuggest are using a proportional ranking method to determine traffic to pages in position 1 to 10.

i.e., position 1 result gets x% of traffic; position 2 result gets y% of traffic.

Traffic to each position	Ubersuggest	Ahrefs
1	5502	Featured snippet
2	2932	People also ask
3	1761	7911
4	1192	3120
5	848	4264
6	611	5172
7	463	915
8	356	802
9	271	690
10	204	1268
11	38	589
12	28	1748

Notice that with Ahrefs estimated traffic, position 10 is greater than the results in positions 7,8 and 9.

And traffic to the page in position 12 is greater than the pages in positions 7,8,9,10, and 11.

If you look at the Ahrefs data in the below screenshot, they show the number of keywords and traffic for each page.

Let’s compare the traffic estimates to each top page regardless of their position.

Traffic to pages in top 10	Ubersuggest	Ahrefs
Shopify	5502	4254
Startups	2932	3120
Entrepreneur Handbook	1192	7911
Entrepreneur	848	1748
Ryrob	1761	5172
Save the Student	850	802
Experian	463	690
Start up Donut	271	915
Start up Loans	356	589

Some of these traffic estimates vary wildly.

So I decided to use Ubersuggest to check the traffic of the top page for the Shopify and Startups pages.

Above, Ubersuggest tells me the Shopify page gets 5502 visits, but the top page’s result tells me the same page gets 8997 visits.

The Startups page above gets 2932 according to Ubersuggest, but the same page in the top pages report gives 4521.

All very confusing.

Features that Ubersuggest doesn’t have

Ubersuggest is a very welcomed and useful addition to the keyword research market.

However, there are features Ahrefs have in their toolkit that Ubersuggest doesn’t have.

Google search engine

Ubersuggest are only pulling data for Google searches, whereas Ahrefs have expanded their keyword research tool to include other search engines.

Amazon search

It is said that more people start their product research on Amazon than on any other website.

So adding in an Amazon keyword research tool is an excellent addition for e-commerce agencies and clients.

I use Amazon keyword research in conjunction with the sales data estimates from Jungle Scout to provide both research and sales data for those looking to source and sell products.

Youtube search

YouTube keyword research tools such as VidIQ and TubeBuddy; we can now do YouTube keyword research inside Ahrefs.

Bing search

Whilst Bing has such a low share of the market; most online marketers neglect it.

So perhaps with a Bing keyword research tool, you can become a big fish in a small pond.

Yahoo search

The same goes with Yahoo; I never hear marketers discuss Yahoo search results but good to know I can research here.

Other search engines

There are various other international search engines that Ahrefs provide keyword research data for.

Useful for others but not for my needs.

Search position history

Ahrefs will show you the search history and volatility of the top 10 results for every search result.

If you see trend lines where the top pages are fairly level, you probably want to omit targeting those keywords.

But if the lines are up and down like a yoyo, then Google may not figure out the best results to rank or what the user wants.

Ubersuggest versus Ahrefs Backlink analysis

SO Ubersuggest recently added a backlink feature to the tool so let’s check it out.

They report that I have 130 referring domains pointing to my website.

Referring domains means a single website.

Ahrefs report I have 206 referring domains.

Ubersuggest estimates I have 807 backlinks.

A backlink is one individual link from one website to yours.

So you could have multiple links from one website; hence why backlinks are more than referring domains.

Ahrefs tell me I have 1560 backlinks.

Now the reason for the difference could be a timing issue.

So maybe Ubersuggest hasn’t crawled my website recently.

Nevertheless, I’ll give them the benefit of the doubt.

Referring Domains per page

The next type of analysis that is important is discovering the links to a particular page.

In this screenshot, you can see both tools report the same number of links to 2 of my pages.

But Ubersuggest hasn’t picked up that I have 12 links to the page at the bottom of each screenshot.

How can they miss so many links?

Best Pages with links

Ubersuggest doesn’t have this type of analysis where I can find my top linked pages.

Ahrefs does this in its best pages by links report.

This is useful to find out the link building strategy a competitor uses to earn links.

Links and Shares

And here’s another analysis Ubersuggest lacks that Ahrefs delivers.

Ubersuggest has a column for Facebook and Pinterest shares per page.

Only one of my pages gets any shares.

However, Ahrefs report that 10 pages have been shared on Twitter, Facebook and Pinterest.

And then Ahrefs go one stage further.

You can also find out who tweeted your article.

That’s powerful.

Competing Domains

Ahrefs kill it with their competing domains feature.

I can find out the traffic the top competitors get in seconds.

And targeting your top 20 competitors ranked pages is one of the best keyword research strategies.

Doing this with Ubersuggest would take hours and days.

Competing Pages

Pop in your website and look at competing pages means you can see what keywords others rank for you that you don’t.

In seconds.

This might result in improving your page content.

A strategy that’s worked wonders for my website and some clients.

Best links by page

This report shows you the pages on a website that have the most backlinks.

Where this is useful is reverse engineering your competitors link building strategy.

For example, I found a client’s competitor got links to infographics and pages they created about hot places and temperatures.

And I found out a recruitment client’s competitor got most of their best links by targeting schools with job seekers resource pages.

Content gap analysis

Plugin your website and a few competitors or industry websites to see the content they rank for that you don’t.

Internal links

Ahrefs will show the internal links to each of your pages.

This is useful when you want to boost the links and rankings of these pages with few or no internal links.

New and lost referring domains

If you do a lot of link building, this data is helpful to track new links.

Alternatively, if you are losing links, this helps convince clients they need to check their page content, start a new campaign, or recover lost links.

Traffic to pages of site’s backlinks

Another keyword research strategy for advanced uses is identifying the traffic to pages that link to you or industry websites.

New backlinks

Similar to the referring domains report.

External broken links

You can check broken external links to competitors or industry websites; ideal for a broken link campaign.

Internal broken links

Check your website does not have broken or 404 pages due to a site audit or content restructure.

Link intersect

You can analyse the links your competitors have that you don’t have and seek out these links.

Domain comparison

Quickly compare the links, traffic and domain rating of lots of similar websites.

Site audit

With the Ahrefs site audit tool, you can identify hundreds of website issues and fix them.

Rank tracker

Track the positions of your pages, keywords and competitors with the site audit tool.

Content explorer

With content explorer, you can discover all kinds of data of pages in the Ahrefs index going back years.

You can find pages that earn shares on various social channels, page traffic, referring domains, and word count.

Find broken links with content explorer

My best link building strategy is broken link building.

Enter a seed keyword and filter by broken links, then sort by referring domains.

Suddenly you have hundreds of link prospects to reach out to and propose your page as an alternative resource.

And yes, I teach broken link building.

Ubersuggest v Ahrefs Video Comparison

Here’s an 18-minute video comparing the differences

TL:DR

Without a doubt, Ubersuggest is a useful keyword research tool.

But in the words of Sean Connery in The Untouchables movie, it’s like bringing a knife to a gunfight.

If it were a boxing match between Ubersuggest and Ahrefs, the contest would be over with the second punch.

Win by knockout; Ahrefs.

Competition for a place in Google’s top 10 search results is a battle.

So new or emerging websites need the tools to compete with their stronger, better-ranked competitors.

You need to right tools to compete, and that’s why Ahrefs is your go-to keyword research tool.
