Enter a competitor and Topicfinder crawls thousands of related sites in parallel, surfacing their best-performing pages instead of making you check one domain at a time.
Real-time SEO metrics and traffic statistics are pulled from multiple APIs and shown next to each topic you find, so you can judge value at a glance.
Sort, filter and refine results with smart filters, keep everything organized in your account, and export hundreds of competitor pages in seconds or email reports to your team.
After you pick a topic, Topicfinder generates optimized title variations automatically and scores them by SEO potential and length, flagging ready-to-use options in green.
