Similarweb vs Keyword Revealer: Competitor Traffic Research or Keyword Difficulty for Your Startup in 2027?
Similarweb and Keyword Revealer both turn up in lists of SEO tools, but they answer different questions. Similarweb estimates how much traffic any website gets and where it comes from: search, social, referrals, ads, countries and, now, AI chatbots. It is a competitor and market research tool. Keyword Revealer tells you which keywords a site like yours can actually rank for: it scores keyword difficulty, shows search volume and cost per click, suggests related ideas and tracks your rankings. Since its relaunch it also checks whether Google's AI Overviews and ChatGPT cite your site. We checked both on their official pages on 2 November 2026.
Quick answer: if you need to know what competitors are doing (how big they are, which channels bring their visitors, which countries they reach), use Similarweb. Its free traffic checker and browser extension cover the basics; paid self-service plans start at $125 a month billed annually. If you need to know what to write next and which keywords a young site can win, choose Keyword Revealer: its Free plan needs no credit card, and Basic costs $12.50 a month billed annually with difficulty scores and rank tracking. Most early-stage startups get the most from Similarweb's free tools plus a cheap Keyword Revealer plan.

Similarweb vs Keyword Revealer at a Glance
Sources: similarweb.com (Web Intelligence pricing, Entrepreneurs view; traffic checker; extension; data methodology) and keywordrevealer.com (home, pricing section and FAQ), checked 2 November 2026. Both show prices in US dollars.
Similarweb: Competitor Traffic and Market Research
Similarweb is a digital market intelligence platform. Type in any domain and it estimates the site's visits and engagement, its traffic sources (direct, organic and paid search, social, email, referrals, display), its top countries, its rank in its category and the keywords that send it search traffic. You do not need access to the competitor's analytics, which is why founders use it to size a market, benchmark rivals and back up the competition slide in an investor deck.
Where the numbers come from: Similarweb's data methodology page lists four sources: first-party analytics from websites and apps that connect their data, an anonymous contributors network of its products installed on millions of devices, public data, and data from partners such as ISPs and measurement companies, which it then models into one view. So the figures are estimates, not a competitor's real analytics. Use them to compare sites and spot trends; small sites with little traffic are the hardest to estimate.
Similarweb free version: what you get without paying
- Website traffic checker: traffic and engagement, global rankings, top keywords, referring domains, search ads and technologies for any domain, and a comparison of up to 5 competitors. When we checked, the search box showed a counter of 3 free searches.
- Browser extension: visits over time, bounce rate and visit duration, traffic sources, countries, keywords with estimated clicks and CPC, top prompts people type into AI assistants about a site, and how much of its traffic comes from ChatGPT, Gemini, Claude, Perplexity and other chatbots.
- Free keyword tool: keyword lists from a seed keyword.
- The limit: Similarweb's pricing FAQ calls its free data a high-level sample without deeper drill-downs; longer history, country filters and full keyword data need a paid plan.
Similarweb pricing in 2027
The Similarweb Web Intelligence pricing page for entrepreneurs (checked 2 November 2026) lists three self-service plans, each for one user:
Each plan has a free-trial button, and the traffic checker page offers a 7-day free trial of Similarweb to try its AEO tools. Entrepreneurs plans can be cancelled from the subscription page and then do not renew after the current period. Note that keyword research and rank tracking start on the $333 plan, so Similarweb is an expensive way to get keyword difficulty alone.
Best for: market sizing, competitor benchmarking, finding which channels work in your category and checking how much traffic AI assistants send to it.

Keyword Revealer: Keyword Difficulty and Content Ideas
Keyword Revealer is still running, but it has changed. It was known as a keyword research tool with a difficulty score for low-competition keywords and a Keyword Tree that shows ideas as branches. It now calls itself an "AEO and GEO intelligence platform": the homepage leads with checks on whether Google's AI Overviews and ChatGPT cite your site, while the keyword, rank tracking and backlink tools sit underneath. Keyword Revealer says it has more than 300,000 users and a database of 3.1 billion keywords.
- Keyword research: monthly search volume, CPC and its own keyword difficulty (KD) score, plus the interactive Keyword Tree for grouping ideas into topics.
- Competitor domain search: its keyword research tool has a second tab for a competitor's domain, showing the keywords and rankings it has, with no signup.
- Rank tracker and backlinks: daily position tracking with drop alerts, and backlink reports with Citation Flow and Trust Flow.
- AI search tools: an AI Overview Simulator with a 0 to 100 AI Visibility Score, a citation monitor for Google AI, ChatGPT and Perplexity, and an AEO Page Generator that turns keyword clusters into pages with FAQ schema.
What it does not do: Keyword Revealer does not estimate a competitor's total traffic, channels, countries or audience. It shows where a site ranks, not how many visitors it gets.
Keyword Revealer pricing
The pricing section on the Keyword Revealer homepage opens on annual billing ("save 40%") in US dollars:
- Free, $0: 50 keyword suggestions per search, 7 keyword evaluations a day, basic metrics, 3 AI visibility audits a day and 1 monitored citation keyword. No credit card needed.
- Basic, $12.50 a month ($150 a year): 50 search credits a day, 100 keyword evaluations a day, 25 tracked keywords, 1,000 backlink rows a day and 25 AI prompt audits a day.
- Pro, $17.97 a month ($216 a year): 300 search credits and 2,000 backlink rows a day, 150 tracked keywords, 150 AI prompt audits a day across Google AI, ChatGPT, Perplexity and Gemini, and the AEO Page Generator (3 pages a day). A banner offers the first month of Pro for $1, then $27.97 a month.
- Elite, $49 a month ($588 a year), and Agency, $41.58 a month ($499 a year): 400 to 500 tracked keywords and 800 search credits a day; Agency covers 5 client domains with white-label reports. Separate AI visibility plans cost $79 to $399 a month billed annually.
- Refunds: the pricing FAQ promises a full refund within 7 days of signing up and cancellation any time. Its older terms page says fees are non-refundable, so confirm with support before you pay for a year.
Best for: choosing keywords a new site can rank for, building a content plan from them and tracking rankings and AI citations on a small budget.

Traffic Research vs Keyword Difficulty: What the Difference Means
- Market view vs page view: Similarweb shows the whole market: who the big players are, how fast they grow and which channels feed them. Keyword Revealer works one keyword at a time and tells you whether a page of yours can rank for it.
- Competitors: both look at competitors, but differently. Similarweb estimates their traffic, channels and audience; Keyword Revealer's domain search shows the keywords they rank for.
- Content ideas: Keyword Revealer is built for them (Keyword Tree, 50 suggestions per search even on the Free plan). Similarweb gives you competitors' top keywords, which are ideas too, but full keyword research needs its $333 plan.
- Price: Keyword Revealer's yearly Basic plan costs $150; Similarweb's cheapest plan costs $125 a month billed annually. Both have free options to test first.
- AI search: both now cover it. Similarweb shows how much traffic chatbots send to any site and what people ask them; Keyword Revealer checks whether AI answers cite your own pages.
What Changed Since the Earlier Version of This Article
- Keyword Revealer relaunched: it now presents itself as an AI search (AEO and GEO) platform. The old article said it focuses only on keyword research with no competitor analysis; it now also has a competitor domain search, rank tracking, backlinks and AI citation checks. It still has no traffic estimates.
- Similarweb's plans were repackaged: self-service plans are sold as Competitive Intelligence bundles that add SEO, AEO (AI search visibility) and ads, from $125 a month billed annually.
- AI traffic data was added: Similarweb's free extension now shows traffic from ChatGPT, Gemini, Claude, Perplexity and other chatbots.
- Removed: the claim that Similarweb lacks keyword clustering, which its official pages do not confirm or deny, and links to third-party blogs. Every fact above comes from the two tools' own pages.
Which One Should You Choose?
- You are writing a business plan or an investor deck: Similarweb, to compare competitors' traffic, channels and countries. Quote its figures as estimates.
- You have a new website and need a content plan: Keyword Revealer, to find keywords with low difficulty before you write.

- You have no budget: Similarweb's free traffic checker and extension for competitors, plus Keyword Revealer's Free plan for keyword checks. Together they cost nothing.
- You run SEO for clients: Keyword Revealer Agency for 5 client domains, or Similarweb's business packages if clients need market data.
How Founders Use Similarweb and Keyword Revealer Together
