Similarweb: Mapping the Competitive Gap
Type: tool
Stage: Stage 2: Positioning Proof
Difficulty: intermediate
Analyze where competitor traffic comes from and identify the specific intent clusters they are winning — revealing which market categories are underserved and where incumbents are weakest.
Overview
Positioning proof requires more than knowing your competitors exist — it requires knowing where they're strong and, more importantly, where they're not. Similarweb gives you a traffic-based view of the competitive landscape: which audiences are visiting your competitors, where those audiences are coming from, and which segments are being systematically underserved by incumbent solutions.
What Similarweb shows you
For any competitor domain, Similarweb provides:
• Traffic volume and trends — is the competitor growing or declining in this category?
• Traffic sources — search, direct, referral, social, paid. A competitor with 80% paid traffic has weak organic positioning.
• Top search keywords — the exact queries driving organic traffic to your competitor
• Audience demographics and interests — who is visiting and what else they're looking at
• Geographic breakdown — where the audience is concentrated
The free tier provides limited data for most domains. Meaningful competitive analysis requires a paid plan or strategic use of the free tier across many competitor domains.
Finding the positioning gap
The most valuable Stage 2 use of Similarweb is intent cluster analysis: identifying which search queries your competitors are winning that you could intercept with a more specific positioning angle.
Process:
1. Identify your three most direct competitors
2. Pull their top 50 organic keywords in Similarweb
3. Sort by traffic volume
4. Look for clusters of keywords that share a common intent or audience (e.g., '[tool] for freelancers,' '[category] without [limitation]')
5. Map those clusters against your product's differentiated strengths
The cluster your competitors are winning with high volume but thin content depth — pages that rank but don't fully answer the query — is your entry point. That's where you can position more specifically and rank more relevantly.
Using Similarweb for positioning validation
Once you've identified a positioning angle (e.g., 'project management for construction compliance'), use Similarweb to validate that the audience exists at scale:
• Search for the keyword cluster in Similarweb's Keyword Research tool
• Check monthly search volume and trend direction — is the intent growing?
• Look at which domains are currently ranking for those queries — are they a good fit for the intent, or is there a relevance gap?
A keyword cluster with growing search volume and weak current coverage by incumbents is a positioning opportunity with quantifiable demand evidence. That's Stage 2 proof.
Free vs. paid tier
The free tier provides:
• Up to 5 website analyses per month
• Limited keyword data (top 5 organic keywords per domain)
• 3 months of historical data
For meaningful competitive analysis, the free tier is enough to establish directional signals but not enough for comprehensive keyword mapping. Consider combining Similarweb's free tier with the free tier of Semrush or Ahrefs to triangulate competitive keyword data without paying for a single full-price subscription.
