Which is Better Semrush or Ahrefs? My Honest Opinion
Hello guys, welcome back to my blog. Today I am going to answer a question I get asked all the time in my emails and DMs, which is better Semrush or Ahrefs. I have personally used both tools for my own websites, so I am not just repeating what other blogs say, I am telling you what I actually feel after using them. In this post I will break down the pricing, the features, the keyword data, the backlink data, and my own personal pick. So lets get into it.
Which is Better Semrush or Ahrefs for SEO in 2026
If you ask me directly, which is better Semrush or Ahrefs, honestly there is no one line answer, because both are great tools but they are strong in different areas. From my own experience, I use Semrush mainly for backlink data, and I use Ahrefs mainly for keyword research because its search volume numbers feel more accurate to me. I will explain why I feel this way in the sections below, with proper facts and tables so you can decide for yourself too.
What is Semrush and What is Ahrefs
Before comparing, let me quickly tell you what both tools actually are, in case you are new to SEO.
Semrush is an all in one digital marketing tool. It helps with keyword research, backlink checking, site audits, competitor research, and even social media and content tools. It started as more of a competitor research tool and slowly grew into a full marketing suite.
Ahrefs is also an all in one SEO tool, but it started with a strong focus on backlinks. Over the years it also added keyword research, rank tracking, site audit, and content tools. Ahrefs is an independent, bootstrapped company, which I personally respect a lot.
Both tools basically do similar jobs, but the way they collect and show data is a bit different, and that is where my personal opinion comes in.
My Personal Opinion – Semrush vs Ahrefs Based on My Own Use
Ok so here is the part you guys are actually here for. In my honest opinion, based on using both tools on my own sites, Semrush is mainly good for backlink data, while Ahrefs is better for keyword research because its search volume numbers feel more accurate to me.
I know a lot of people online will say Ahrefs is the backlink king, and I am not saying Ahrefs backlink tool is bad, it is good also. But when I personally check backlinks, I feel Semrush shows me more detail and more backlink history for a domain. On the other hand, when I do keyword research in Ahrefs, the search volume numbers match closer to what I actually see in Google Search Console after ranking, compared to Semrush.
This is just my personal experience guys, not a rule for everyone. I think it is always good to try the free versions or trials of both and see which one matches your own workflow.
Semrush vs Ahrefs Backlink Data Comparison
Backlinks are a big part of SEO, so let me show you a simple table comparing backlink data of both tools, based on their own official numbers.
| Point | Semrush | Ahrefs |
|---|---|---|
| Backlink Database Size | 43T+ backlinks | 35T+ backlinks |
| Domains Indexed | 808M+ domains | Large, updated often |
| Own Crawler | Yes, proprietary crawler | Yes, called AhrefsBot |
| Pages Crawled | Around 10B pages daily | Very high, among top crawlers |

As you can see, on paper Semrush actually shows a bigger backlink number then Ahrefs. But honestly, a bigger number does not always mean better quality data. I think what matter more is how fresh and clean the data is, and both companies claim their crawler is very active. Cloudflare Radar also tracks bot traffic, and both AhrefsBot and Semrush’s bot show up as some of the most active crawlers on the internet.
Semrush vs Ahrefs Keyword Research Comparison
Now lets talk about keyword research, which is the part I personally care about more.
| Point | Semrush | Ahrefs |
|---|---|---|
| Keyword Database | 28B+ keywords | 28.7B+ keywords, filtered from 110B |
| Regional Databases | 142 regional databases | Available for many countries |
| Search Volume Accuracy (my opinion) | Good, but sometimes feels off | Feels more accurate in my own testing |
| Keyword Difficulty Score | Yes | Yes |

I always tell my readers, if keyword research is your main need, I personally lean towards Ahrefs. The search volume it shows for my own niche keywords match closer to the real traffic I get once I rank, compared to what Semrush shows me. But again, this can be different for other niches also, so do not take my word as 100% final.
Semrush vs Ahrefs Pricing Comparison
Pricing is also a big factor, so here is a simple table with the current plans of both tools.
| Plan Type | Semrush | Ahrefs |
|---|---|---|
| Entry Plan | SEO plan around $139/mo | Starter around $29/mo |
| Mid Plan | Starter plan around $199/mo | Lite around $129/mo |
| Higher Plan | Pro+ around $299/mo | Standard around $249/mo |
| Top Plan | Advanced around $549/mo | Advanced around $449/mo |
| Free Option | Limited free plan | Ahrefs Webmaster Tools (free) |

If you ask me, Ahrefs feels a bit more friendly for beginners because of the cheap Starter plan and the free Webmaster Tools option. Semrush entry plan straight away starts higher, but it also bundle in a lot of other marketing features like content and social tools, so you are paying for more then just SEO.
Other Features Worth Knowing
Both tools have more then just backlinks and keywords, so let me list a few other things quickly.

- Rank Tracker – Both let you track your keyword rankings over time on Google and other search engines
- Content Tools – Semrush have more content and social media tools bundled in, while Ahrefs keeps it more focused on core SEO
