What are SEMrush and Ahrefs

The two most common are Semrush and aHrefs. SEMrush and Ahrefs have both been on the market for a long time and are known as powerful SEO tools for digital marketers.

SEMrush and Ahrefs are both paid tools, which means they offer advanced features and capabilities often not available in free tools.

What is Semrush

SEMrush is a renowned SEO tool used by many professionals in the digital marketing world. Many digital marketers use because it is a versatile and powerful tool that insights and tools dashboard are attractive and easy to use.

What is aHrefs

Ahrefs is another popular SEO tool used by digital marketers. Like SEMrush, it offers a wide range of features and capabilities to analyze and improve Web sites for search engines.

With Ahrefs, for example, you can track your website's position in search results, do keyword research to see which search terms are performing best, and perform competitor analysis to see how they approach their SEO.

Unlike SEMrush, Ahrefs also offers a comprehensive keyword research tool that allows you to see how much search traffic certain keywords generate and how difficult it is to rank for those keywords. This can help determine the most profitable keywords for your Web site.

2. SEMrush VS Ahrefs: the features at a glance

Let's do an in-depth comparison of the features and capabilities of SEMrush and Ahrefs, and look at the strengths and weaknesses of each tool to see which one best suits your needs.

There is no simple answer as to which tool is best for SEO keyword research because it depends on several factors. Both Semrush and Ahrefs offer comprehensive tools for keyword research, and both use complex algorithms and data from different sources to identify relevant keywords and keyword groups.

Keyword Research for SEO: A Comparison of SEMrush and Ahrefs


To use Semrush for keyword research, you can follow the following steps:

  1. Enter a keyword or keyword group in the search field to have the tool search for relevant keywords and keyword groups.
  1. Review keyword research results to see which keywords and keyword groups are most relevant to your audience and goals.
  1. Use the data Semrush provides, such as search volume, competition and keyword variations, to refine your keyword strategy and determine which keywords to use in your content and marketing campaigns.

SEMrush allows you to see all the keywords for which a competing site is currently ranking. The "Organic positions" feature in SEMrush is similar to the one in Ahrefs, with a few minor differences.  

For example, SEMrush and Ahrefs both use different methods to estimate how much organic traffic a site gets from their first page rankings. However, the unique thing about SEMrush is that its "Organic Positions" report provides much more in-depth keyword data than Ahrefs. 

Ahrefs basically shows you search volume, CPC and competition for specific keywords. SEMrush provides comprehensive information about each term, such as search volume trend and number of results for the search term.

It's up to you whether the rich amount of data SEMrush offers is an advantage or disadvantage, depending on your needs. Personally, I like to focus on key metrics, which means SEMrush's user interface can sometimes feel a bit overcrowded.

If you're a keyword analyst who needs to quickly analyze 100+ terms, having everything you need in one place is super convenient. Fortunately, Semrush offers a traditional keyword research tool that allows you to see a keyword's search volume and competition.

Having SEO and PPC data at your fingertips can be SUPER useful


Ahrefs has two main keyword research features:

  1. Keywordexplorer
  2. Organic keywords
  3. SERP Comparison - a new cool feature

Let's see how each works.

Ahrefs' Keyword Explorer is a powerful keyword research tool that offers more than just the search volume of a keyword. For example, Keyword Explorer also shows you how many clicks you would get if you ranked for that keyword. 

This is important because it gives you an idea of the potential traffic you can expect if you optimize your website for a particular keyword.

It is also helpful that Ahrefs Keyword Explorer provides you with information on the number of searches and clicks on specific keywords.

Clicks tell us how many times a specific keyword was clicked on during a specific time period. A great addition!

Why is this important?

It is important to know how many clicks a keyword generates. This is important because Google is making its search results pages (SERPs) increasingly crowded with features that take clicks away from organic search results. Read our article; What is a Featured Snippet where it 

Moreover, Keyword Explorer also provides data related to the keyword you are researching, which can help you refine and improve your strategy.


  • Ahrefs: A powerful SEO tool for researching keywords, backlinks and website analysis.
  • SEMrush: A comprehensive SEO tool for improving search engine rankings, discovering competitors and monitoring online visitor behavior.

When it comes to keyword research, both tools offer excellent capabilities. However, SEMrush is better suited for digital marketers and agencies, as it offers a wide range of marketing-related features, such as ad research, competitive analysis and website audit. Ahrefs, on the other hand, is aimed more at SEO specialists and copywriters, with specific features for link building and content creation, such as backlink analysis and content-based keyword research.

It is important to choose the right tool to suit your specific needs and goals. For example, if you are primarily concerned with improving the SEO of your website, Ahrefs is probably a good option. On the other hand, if you want to work on a broader digital marketing strategy, SEMrush may be a better fit for your needs.
