Semrush vs Similarweb
Semrush vs Similarweb: compare an SEO-first suite with a market intelligence platform by data focus, packages, users, and trials.
The decision in brief
They start from different questions. Semrush is built around search: keywords, rankings, backlinks, and audits, with traffic and market data as a separate toolkit. Similarweb is built around estimating any website's traffic, engagement, and marketing channels, with SEO and ad intelligence in its higher packages and business plans quoted by sales.

Compare the working details
| Decision factor | Semrush | Similarweb |
|---|---|---|
| Main focus | One account for most search marketing research, which you extend with specialist toolkits as needs grow. | Benchmarking competitors' whole traffic mix and market share, not only their organic search. |
| 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. | Enter your site and competitors, compare traffic, engagement, and channels, then use keyword research, rank tracking, or ad insights in the packages that include them. |
| 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. | Self-serve packages for individuals and small teams include one user and three or six months of history; keyword research and rank tracking start at the second package. Business packages are priced through sales. A free trial and limited free data on its site are available. |
| 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. | Its figures are estimates and can differ from your own analytics, so compare them with a site whose real traffic you can see. |
Which belongs on your shortlist?
Consider Similarweb when…
Shortlist Similarweb when you need to benchmark competitors' whole traffic mix, such as paid, social, and referral, for market research or strategy.
Run the same evaluation in both
- Choose three competitors and run each tool's traffic overview for the same country and period.
- Compare both estimates with a site whose real analytics you can see, and note the gap.
- Check which package or toolkit unlocks the reports you used in the trial, and how many users and months of history it includes.
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 | Similarweb |
|---|---|---|
| Look up the 20 seed keywords Volume, difficulty, and intent for each keyword in the chosen country, with any keyword that returns no data noted. | ||
| 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. |
