If you already know these two tools and just want to know the final conclusion, feel free to scroll down to the end of the article. If not, let's explore with RankMarket right now!

1. What are Ahrefs and SEMrush? An overview

What is Ahrefs?

Ahrefs is a famous SEO tool, founded in 2011 by Dmitry Gerasimenko. Ahrefs started out as a backlink analysis tool that was unrivaled – and it did a pretty good job of that, with its massive database that allowed users to track backlinks from all over the internet.

Over time, Ahrefs has expanded into a comprehensive suite of tools, including keyword research, site audits, rank tracking, and more. Currently, Ahrefs boasts over 10 billion keywords and 16 trillion backlinks in its database, covering 171 countries.

What is SEMrush?

SEMrush, launched in 2008 by Oleg Shchegolev and Dmitri Melnikov, is positioned as an “all-in-one” tool for digital marketing. It is an SEO tool and a comprehensive Digital Marketing support platform. With over 26.3 billion keywords, 808 million domain profiles, and 43 trillion backlinks (according to the latest data from SEMrush in March 2025), SEMrush serves everything from keyword research, competitor analysis, PPC ad management, to social media monitoring. Its strengths lie in its diversity and deep integration with the Google ecosystem.

So, between these two “giants”, who will be the leader at the moment? To answer that question, I will compare based on 7 main criteria:

• Interface (UI)
• Features
• Backlink data
• Traffic estimates
• Keyword research
• Price
• Usage limits

2. User interface (UI):

The interface is the first thing you “encounter” when using a tool. It can make you fall in love at first sight, or make you “sweat” because it is too complicated. Let’s see how Ahrefs and SEMrush perform in this regard.

Ahrefs Interface

If you’ve used Ahrefs before, you’ll find its interface to be pretty intuitive. The main tools are neatly listed on the left sidebar, while the top menu adds a few more options. For example, when I enter a domain like “example.com” into Site Explorer, I immediately see an overview of the domain rating (DR), number of backlinks, and organic keywords. Want to see more keyword details? Just click “Organic Keywords” – everything is clear, clickable, and easy to explore. For me, who has used Ahrefs for many years, everything here feels like “home” – familiar and comfortable.

SEMrush Interface

Stepping into SEMrush, my first impression is that it is quite similar to Ahrefs, but a bit more “colorful”. In the Domain Overview section, you also get basic metrics like Authority Score, Organic Traffic, Backlinks – similar to Ahrefs. However, SEMrush scores with beautiful visual charts, making it easier for you to visualize the data. For example, when viewing keywords, I like the way SEMrush displays search trends using graphs – a small but very useful plus. However, if you are new to it, it may take a few minutes to get used to it because it crams a lot of information onto one screen.

SEMrush's tools are also listed on the left sidebar, from Keyword Research, Link Building to Social Media Tracker. The difference is that SEMrush has more filters and detailed options right on the main screen, helping you to operate quickly without having to switch pages a lot. For beginners, SEMrush can be more accessible thanks to its vivid presentation and clear instructions.

Honestly, both do their job well. Ahrefs tends to be simple and neat, suitable for those who are familiar with SEO tools. SEMrush stands out with data visualization and friendliness for beginners. I'll give both of them a 1 in this category – neither one is better than the other!

3. Features: Which tool is more “comprehensive”?

Do you use SEO tools for keyword research, backlink analysis, or website optimization – what do Ahrefs and SEMrush have in their arsenal?

Ahrefs Features

Ahrefs focuses on the core of SEO: backlinks, keywords, and website audits. Some of the features I use on a daily basis include:

• Backlinks: The Site Explorer tool lets you see the details of your backlinks, from the number of referring domains to the anchor text. You can also find broken backlinks to take advantage of link building opportunities.
• Keyword Research: Keywords Explorer provides data on keyword difficulty (KD), search volume, and CPC. I often use it to find potential keywords for SEO campaigns.
• Site Audit: This feature scans your website, gives you an overall health score, and points out what needs fixing – from broken links to technical issues.

Ahrefs also has Content Explorer – a great tool for finding popular content in your niche. The data can be exported to CSV files or integrated with Looker Studio, which is handy if you like deep analysis.

SEMrush Features

SEMrush goes the “all-in-one” route. In addition to the same features as Ahrefs, it adds a few tools that I didn’t expect:

• Keyword Magic Tool: This tool makes keyword research super easy. You enter a seed keyword, it will suggest a series of related keywords with search intent (search intent) – something Ahrefs doesn't have.
• Site Audit: Similar to Ahrefs, but the interface is nicer and the reporting is a bit more detailed.
• Link Building Outreach: SEMrush allows you to connect your email directly from the platform to contact for backlinks – a big plus if you do outreach regularly.
• Additional Tools: From Social Media Tracker (additional fee), SEO Writing Assistant, to Local SEO management (NAP – Name, Address, Phone Number), SEMrush is almost a “treasure” for Digital Marketers.

Ahrefs is strong in its specialization in-depth, especially with backlinks and keywords. But SEMrush excels thanks to its diversity and additional features like outreach and local SEO. For me, SEMrush wins this round by 1 point, because it brings more value to comprehensive campaigns.

4. Backlink Data:

Backlinks have always been the “heart” of off-page SEO. Backlinks have long been Ahrefs’ strength, but will SEMrush catch up in 2025?

Ahrefs vs Backlinks

Ahrefs has long been known as the “king of backlinks”. When I checked a site like “epicgardening.com”, Ahrefs reported 10,500 referring domains and 205,000 backlinks. It also showed historical data (all-time backlinks), which helped me see link growth trends over time. What I like is the ability to filter in more detail – for example, only see backlinks from high DR domains or from specific pages.

SEMrush with Backlinks

SEMrush used to be underrated for backlinks, but now it has “stepped up” significantly. For the same site “epicgardening.com”, SEMrush produces 15,500 referring domains and 667,000 backlinks – significantly more than Ahrefs.

SEMrush clearly outperforms Ahrefs in terms of the amount of backlink data. While Ahrefs is still strong in its detailed analysis capabilities, SEMrush wins this round by 1 point thanks to its much larger database.

5. Traffic Estimation: Which is More Realistic?

Traffic estimation is a tough test, especially since Google keeps updating its algorithm. I tested both tools on my sites to see how accurate they are.

Results from Ahrefs

• Site 1 (downhill): Ahrefs estimated 8,700 organic visits/month. Actual from Google Analytics: 11,000 visits. Error of 2,300.
• Site 2 (downhill): Ahrefs reported 19,300 visits, actual 12,000 visits. 7,300 deviation.
• Site 3 (upward): Ahrefs reports 2,000 visits, actual 1,020 visits. 980 deviation.

Ahrefs reacts fairly quickly to traffic changes, but its estimates are often a bit off. The reason for this is that Ahrefs focuses on data from ranking keywords, multiplied by the average click-through rate (CTR) to estimate organic traffic. Ahrefs' strength is its Traffic Potential metric, which is more realistic when taking into account factors like Featured Snippets. However, it tends to underestimate traffic for sites with diverse traffic sources other than organic.

Results from SEMrush

• Site 1: SEMrush reported 3,400 visits, actual 11,000 visits. Error 7,600.
• Site 2: SEMrush reported 5,600 visits, actual 12,000 visits. Error 6,400.
• Site 3: SEMrush reported 2,400 visits, actual 1,020 visits. Error 1,380.

SEMrush tends to underestimate traffic, especially for sites with high volatility. This is probably because SEMrush uses clickstream data from multiple third-party sources, combined with machine learning models to predict traffic. So, SEMrush is pretty accurate for large websites, but for small sites (under 5,000 visits/month), the error can be up to 50%.

While neither is perfect, Ahrefs is a little more realistic thanks to its quick response to changes. 1 point for Ahrefs!

6. Keyword research:

Keyword research is the foundation of any SEO campaign. If you don’t choose the right keywords, all your efforts can go down the drain. So how well do Ahrefs and SEMrush do in this area?

SEMrush with Keywords

SEMrush has the Keyword Magic Tool – an extremely powerful “weapon”. When you enter a primary keyword, the tool will provide:

• Search Intent: Helps you understand what users want (information, shopping, navigation, etc.).
• Keyword Clusters: Suggests groups of related keywords to optimize content.
• Number of Ads: Shows the level of competition on Google Ads.

SEMrush excels in keyword quantity (especially with Reddit), and I love the Search Intent feature – which categorizes keywords into navigational, informational, transactional, commercial. Using the same filters as Ahrefs, SEMrush returns 86,400 keywords – 30,000 more!

Ahrefs with Keywords

Ahrefs takes a different approach than Keywords Explorer. What makes Ahrefs unique is its Traffic Potential metric – a number that estimates the actual traffic a keyword could bring, rather than just relying on search volume. Why is this important? Because Google has so many factors like Featured Snippets or cross-site ads these days, not all high-volume keywords bring in high traffic.

For example, with the keyword “best SEO tools”, Ahrefs will tell you not only the volume but also the actual traffic prediction based on the current SERP situation.

In conclusion, SEMrush is still the winner in the Search Intent keyword research category.

7. Price and Limits: Which is More Affordable?

Ultimately, it comes down to money. Which tool is worth the money?

Ahrefs Pricing

Ahrefs has a Lite plan starting at $129/month, but to get the full features (like Content Gap), you need the Standard plan $249/month. The problem is the credits system – each time you open a report or filter data, you spend 1 credit. For my 1,100 credits/month usage, I had to pay an additional $70/month – totaling $269/month.

SEMrush Pricing

SEMrush starts at $117/month (Pro), with 5 projects and 500 tracked keywords. The Guru plan ($208/month) gives you 15 projects and Looker Studio integration. There’s no credit limit like Ahrefs, just a limit on the number of reporting rows (30,000 on Pro).

If you’re working solo or on a limited budget, Ahrefs can be more cost-effective. But if you manage multiple projects or a large team, SEMrush offers better value thanks to its flexibility and free trial.

SEMrush is cheaper and more flexible for heavy users. 1 point for SEMrush!
