Shortlist Semrush when you want SEO research plus the option to add traffic, local, content, or social toolkits under one account, and a trial of the full plan matters.

Semrush vs Ahrefs
Semrush vs Ahrefs: compare two all-in-one SEO suites by free access, per-user pricing, add-ons, and research focus, using official pricing pages.
The decision in brief
Both cover keyword research, competitor and backlink analysis, rank tracking, and site audits, and both now track AI visibility. Semrush has a free account with 10 reports a day, a seven-day trial, and separate toolkits for traffic, local, content, and social. Ahrefs builds on its own web index, offers a permanent free account for sites you verify, and bills each extra user on top of plans that include one.

Compare the working details
| Decision factor | Semrush | Ahrefs |
|---|---|---|
| Main focus | One account for most search marketing research, which you extend with specialist toolkits as needs grow. | Backlink, competitor, and keyword research from Ahrefs' own crawl data, with audits and rank tracking for your sites. |
| Working setup | Create a project for your site, research keywords and competitors, set up position tracking and a site audit, then add toolkits or users as needed. | Verify your site or add a project, research competitors in Site Explorer and keywords in Keywords Explorer, then set up Site Audit and Rank Tracker. |
| Pricing model | A free account allows 10 reports a day and one demo project. Paid plans combine the SEO and AI Visibility toolkits and differ by websites and tracked keywords; extra users and specialist toolkits are paid add-ons. Paid plans have a seven-day free trial. | Ahrefs Free gives permanent, limited access for websites you verify. A low-cost Starter plan covers basic research. Lite, Standard, and Advanced each include one user, with extra users paid per month; Lite has a monthly credit allowance per user. |
| What to verify | Price the plan together with every toolkit and extra user you need: traffic and market data, local, content, and social tools are separate subscriptions. | Each extra user is billed monthly, Lite allows 1,000 credits per user a month, and Traffic Analytics and Brand Radar AI are paid add-ons. |
Which belongs on your shortlist?
Consider Ahrefs when…
Shortlist Ahrefs when backlink and competitor research is the core of the work, and you would start with its free account for your own sites or its Starter plan.
Run the same evaluation in both
- Pick one competitor domain and ten keywords, and run the same lookups in Semrush's trial and Ahrefs' free account or Starter plan.
- Compare backlink counts, keyword volumes, and difficulty scores against what you know about a site you own.
- Price both for your number of users, tracked keywords, and add-ons for a year, then decide.
Try the same task before you choose
Research one keyword set and three competitors
Use the same fictional brief in each candidate. Pantry Pilot, a made-up meal-planning app with no website yet, wants to understand its market in one country. Use the same 20 generic seed keywords, such as 'meal planner app' and 'weekly meal plan template', and let each tool suggest three competitor domains from them. Compare the data each tool returns and what the work uses from its limits.
Every check starts as Not run. Record your own observations; these are evaluation criteria, rather than completed product tests. Your worksheet stays in this page and can be downloaded.
| Task and expected observation | Semrush | Ahrefs |
|---|---|---|

| Find three competitors from the seed set Three domains that rank for several seed keywords, with the shared keywords listed. | ||
| Compare the competitors' keywords Keywords that at least two of the competitors rank for in the top ten, exported or copied into a list. | ||
| Review one competitor's backlinks Referring domain count and the top ten linking domains, with any row limit on the report recorded. | ||
| Estimate the competitors' traffic A monthly traffic estimate for each, with a channel breakdown if the plan includes one, labelled as an estimate. | ||
| Track ten keywords for one competitor Rank tracking set up for the chosen country, with update frequency and when the first results arrived noted. | ||
| Count usage and seats Reports, queries, or credits used for this brief against the plan's limits, and whether a second person needs a paid seat to see the results. |
