What our research says

Probedex

Probedex packages competitor data into a written teardown instead of leaving you to interpret raw traffic and SEO numbers yourself. The free discovery tier is genuinely limited, so real use means paying per teardown or subscribing.

Pros

  • Aggregates traffic, SEO, ad, and revenue signals from multiple sources into one report
  • Pay-per-teardown option ($19.90) for occasional use without a subscription
  • Watchlist and CSV export on paid tiers
  • Cancel-anytime pricing with no annual lock-in

Cons

  • Free tier's discovery access is narrow (10 companies per page, top 3 results)
  • Extra teardowns beyond the monthly allowance cost $19.90-29.90 each
  • Company country and founding details aren't published

Similarweb

Similarweb is the incumbent in traffic estimation, and the AI-visibility tracking is a real extension rather than a badge: it measures how often the major chatbots surface your brand, which is becoming its own channel. The pricing is the friction — nothing is self-serve, so you talk to sales before you know the number.

Pros

  • Coverage across websites, apps and retail SKUs
  • AI Search Intelligence tracks citations across six chatbots
  • Documented data API alongside the dashboards
  • Named company with a real headquarters

Cons

  • No published pricing at any tier
  • Traffic figures are modelled estimates, not measured truth
  • Founding year is not stated on the site
