Serpstat vs Similarweb: SEO Keyword and Rank Platform or Competitor Traffic Intelligence?
Serpstat and Similarweb both show you data about other people's websites, but they are built for different jobs. Serpstat is an all-in-one SEO platform: keyword research for Google and Bing, daily rank tracking, a site audit crawler, backlink analysis and competitors' ads. Similarweb is a traffic and market intelligence platform: it estimates how many visits any website gets, from which channels, countries and devices, how much now comes from AI chatbots, and how a whole category is moving. So in any Similarweb vs Serpstat decision the first question is simple: do you need to rank your own pages, or do you need to understand how big your competitors and your market are? We checked both official websites on 10 November 2026: plans and prices as the pricing pages show them by default, free options, trials and what each plan includes.
Quick answer: for a startup that does its own SEO, Serpstat is the better first buy: Individual costs $50 a month on yearly billing ($600 upfront) and includes keyword research, 10,000 rank checks, a site audit and backlinks, after a 7-day free trial. Similarweb is the tool for traffic and market questions, for example in a pitch deck, a market-entry plan or a partner search: start with its free browser extension and free traffic checker, and pay only if you need the full data, from $125 a month billed annually or $199 monthly for one user. Similarweb's own keyword research, rank tracker and site audit start in its $333 a month (billed annually) plan.

Serpstat and Similarweb in 2027: What Each One Does
Serpstat: keyword research, rank tracking and site audits in one subscription
Serpstat was built by the agency Netpeak in 2013 and has been independent, as part of Fractal, since 2015. It covers Google and Bing, with keywords from 230 countries (keyword difficulty, search volume and cost per click), competitor analysis for SEO and pay-per-click, competitors' ads, a rank tracker with a flexible schedule for desktop and mobile, a site audit with prioritised fixes and backlink analysis. It is the tool you open when you decide which keywords to write for, check whether last month's articles moved up, and fix the technical errors that hold a site back.
- Individual, $50 a month on yearly billing ($600 upfront): 5 projects, 100 searches for sites, keywords and links per day, 10,000 keyword position checks, 30,000 pages to audit (up to 5,000 per scan, no JavaScript rendering) and 50,000 export rows, for one user. No API and no AI Visibility.
- Team, $100 a month ($1,200 upfront): unlimited projects, 500 searches a day, 50,000 position checks, 150,000 audit pages, 3 users, 200,000 API credits, a ChatGPT and Claude integration (MCP) and 1,500 AI Visibility checks a month. Team x2 costs $169 a month with double the limits and 6 users.
- Agency, $410 a month ($4,920 upfront): 5,000 searches a day, 500,000 position checks, 3,000 AI Visibility checks, 30 users and white-label reports.
- On every plan: competitors' rankings, daily updates, organic and paid keyword rankings, desktop and mobile rankings, and free project migration from another service.
Trial and billing: the Serpstat pricing page opens on annual billing ("save up to 27%"); the monthly prices sit behind a toggle, so we do not quote them. The free 7-day trial gives you Individual or Team. You enter a card, Serpstat charges $1 to verify it and returns it within 5 to 30 minutes, and the plan renews automatically after 7 days unless you cancel. AI Visibility, formerly LLM Brand Monitor, shows how ChatGPT, Grok, Gemini and other AI models mention your brand; extra checks cost $20 per 1,000.
Traffic data in Serpstat: Serpstat also has a website traffic checker that estimates the traffic of any website. A free account checks 10 websites a day, and paid plans add bulk analysis of up to 5,000 domains at once. It is useful for a first look at a competitor's search visibility, but it does not break traffic down into channels, audiences and countries the way Similarweb does. The free Serpstat browser extension for Chrome, Firefox, Opera and Edge works for registered users with a limited number of credits.
Best for: founders and small teams who write and optimise their own pages and want keyword research, daily rankings and a site audit in one subscription.

Similarweb: traffic, channels and market benchmarks
Similarweb estimates the traffic of any website and breaks it down by channel, country, device and audience, so you can compare competitors and whole categories. Its higher Entrepreneurs plans add SEO tools (organic search overview, keyword research, rank tracker, site audit and backlinks), AI brand visibility for tracked prompts and ad intelligence. For founders it answers questions an SEO platform does not try to answer: how big is a competitor really, which channels bring it visitors, which countries matter, and how much traffic now comes from ChatGPT, Gemini, Claude and Perplexity.
- Competitive Intelligence, $125 a month billed annually or $199 monthly: 1 user, 3 months of history: website performance, traffic and engagement, customer demographics, marketing channels overview and competitor alerts.
- Competitive Intel & SEO & AEO, $333 a month billed annually or $399 monthly: 6 months of history, adding organic search overview, keyword research, rank tracker, site audit and backlinks, and AI brand visibility with 150 tracked prompts, sentiment, citation analysis and AI traffic.
- Competitive Intel, SEO & AEO & Ads, $542 a month billed annually or $649 monthly: adds creative and campaign insights, search and display ads, advertiser demand signals and ad spend.
- Business packages: the default tab of the Similarweb pricing page sells custom packages through sales, with up to 37 months of data, 100+ countries, AI Studio, AI agents, APIs, data feeds and MCP. The prices above are on its Entrepreneurs page.
- Trial and cancelling: Similarweb's support centre says you are billed automatically after the 7-day free trial unless you cancel before it ends. Entrepreneurs plans are cancelled inside the platform and stop at the end of the billing period.
Free tools: the Similarweb extension is free on Chrome, Edge, Firefox and Opera and needs no account. It shows visits over time, AI chatbot traffic, top prompts, keywords, rankings, traffic sources by channel and geography for the site you are on; Similarweb notes that very small websites may return partial data. The free website traffic checker gives 3 searches a day and compares up to 5 competitors. Similarweb itself calls free data a high-level sample of the paid platform.
Best for: founders who need traffic benchmarks for a pitch deck, a market-entry decision, partner or acquisition research, or a check on how fast competitors grow.

- You publish content and want to rank on Google: Serpstat Individual. Keyword research, daily rank tracking and a site audit cost less per year than one Similarweb plan.

- Pick the keywords. In Serpstat, look up the competitors with the most organic keywords, export the ones you do not rank for and group them into one page per topic. Our guide to SEO keyword research tools for startups compares other options.
- Choose your stack. Ahrefs vs Semrush and Ahrefs vs SE Ranking cover the bigger suites; for cheaper picks see Semrush alternatives, Ahrefs alternatives and free Ahrefs alternatives.
- Measure your own site. Competitor tools estimate; your own analytics count. See free Google Analytics alternatives, open-source Google Analytics alternatives and Google Analytics 4 alternatives.
- Publish and track. Write one page per keyword group, then track it daily or weekly in Serpstat; check AI chatbot traffic as well as Google.
If competitors get little traffic and nobody searches for your keywords, that is a signal to validate your startup idea before you build. Research only pays off when you publish: the F/MS AI SEO Tool turns your keywords into articles built to rank on Google and to be cited by ChatGPT and Perplexity, with human editors checking the result.
