Tag: Semrush vs Ahrefs

Semrush and Ahrefs are the two SEO tools everyone ends up choosing between, and both are good. The right one depends on what you’ll use it for and how you like to work. Here’s an honest, side-by-side look with the 2026 prices.

How do Semrush and Ahrefs prices compare?

Ahrefs is cheaper to get into and Semrush is cheaper at the top end. Ahrefs’ $29 Starter plan has no Semrush equivalent, while Semrush’s SEO plan at $139 sits close to Ahrefs Lite at $129.

Sources: Semrush and Ahrefs pricing pages, checked 20 October 2026. Both save up to 17% on yearly billing. US dollars; VAT may apply.

Watch the limits as well as the prices. Semrush’s SEO plan tracks 500 keywords across 5 websites. Ahrefs Lite tracks 750 keywords with 5 non-verified projects, 6 months of history and 1,000 credits per user, and the credit cap is the limit Lite users tend to notice. Ahrefs Standard removes the credit cap and adds two years of history.

Extra users cost money on both. Semrush charges from $45 a month per extra user on its SEO and Semrush One plans; Ahrefs charges $40, $60 or $80 depending on the plan.

Do Semrush and Ahrefs have free trials?

Semrush has a 7-day free trial on its SEO plan, Semrush One and most toolkits, plus a free account with 10 reports a day. Ahrefs doesn’t run free trials; its FAQ says it never runs discounts. Instead, Ahrefs Free gives website owners limited access to Site Explorer and Site Audit for their own sites.

That difference matters if you want to test before you buy. With Semrush you can run a full audit, a keyword gap and a week of rank tracking on your own site before paying anything. My guide to the Semrush free trial shows how to use those 7 days.

Which is better for keyword research?

Semrush is my pick for keyword research, mainly because of its database size and the way it labels search intent. Semrush says it holds 28 billion keywords across 142 country databases, and the Keyword Magic Tool groups thousands of results into topic folders you can filter by difficulty, volume and intent.

Ahrefs’ Keywords Explorer is also excellent, with clear difficulty scores and click data that shows how many searches lead to a click. If you already know how to read keyword data, you’ll be well served by either. If you’re newer, Semrush’s intent labels and grouping make the list easier to act on. My keyword research guide covers the method that works in both.

Which is better for backlinks?

Ahrefs has the stronger reputation for backlink research, and if link building is the centre of your SEO work, that’s a fair reason to choose it. Its interface for exploring referring domains, new and lost links and anchor text is very good.

Semrush is no slouch here: it reports 43 trillion backlinks in its database, and Backlink Analytics, Backlink Gap and Backlink Audit cover research, prospecting and spotting toxic links. For a small business that needs to see who links to competitors and find a few good link opportunities, Semrush is plenty.

Which is better for site audits and rank tracking?

Both run solid site audits and daily rank tracking; Semrush explains fixes more clearly for non-technical owners. Semrush’s Site Audit sorts issues by severity with a plain-English “how to fix” note on each, and on Semrush One it also checks AI readiness, including whether AI crawlers can reach your pages.

For rank tracking, Ahrefs Lite tracks more keywords for the money (750 against 500). Semrush’s Position Tracking is strong for local tracking down to city level and, on Pro+, across multiple locations and devices.

Which is better for AI search visibility?

Semrush is further ahead on AI visibility for small and mid-sized businesses. Semrush One Starter, at $199 a month, tracks 50 prompts daily across ChatGPT, Google’s AI features, Gemini and Perplexity, alongside the full SEO toolkit. The separate AI Visibility toolkit starts at $99 a month per domain.

Ahrefs includes a number of AI prompt checks in each plan (150 on Lite) and sells Brand Radar AI from $199 a month, with a large database of prompts for brand research. It’s a capable offering. If you want SEO and AI tracking under one login and one bill, Semrush One is the simpler choice.

Which is easier to learn?

Semrush is easier for beginners. Every report follows the same layout, the main tools are clearly signposted, and Semrush Academy has free lessons for each one. My honest experience is that it’s very easy to understand once you’ve used the five core reports.

Ahrefs has a clean design that experienced SEOs love, but newcomers often find it harder to know where to start, and the credit limits on Lite make people nervous about clicking around. For a business owner doing their own SEO a few hours a week, I’d start with Semrush.

Semrush or Ahrefs: which should you choose?

Choose Semrush if you want the most complete single tool for website SEO and AI search, an easier learning curve, and a free trial to test it first. Choose Ahrefs if you’re link-focused, you want the $29 Starter plan for occasional research, or your team already knows it well.

For most of the small businesses, bloggers and creators I work with, Semrush is the better fit. My full Semrush review gives it 4.5 out of 5. If you’d like to see both side by side with a few more options, my Semrush alternatives guide has the full list.
