Map your competitor's content strategy in 20 minutes and find your openings

Use SimilarWeb's free tier and a structured sheet to identify content topics your competitors cover versus gaps you can own.

  1. 1Go to SimilarWeb.com. Enter your main competitor's domain. Note their top 5 traffic sources and scroll down to see their top content pages (sorted by traffic).
  2. 2Create a Google Sheet with three columns: Topic, Competitor Covers, You Cover. List the 12-15 top content topics from their traffic data in the first column.
  3. 3Quickly scan your own website (use Ctrl+F and search your site) or ask your content manager: do you have content on each of those topics. Mark Yes or No in the third column.
  4. 4Open Perplexity AI. Ask it: 'What are 5 underserved content topics for [YOUR_INDUSTRY] that drive search traffic but are not heavily covered by [COMPETITOR].' Copy the response into a fourth column.
  5. 5Review the results. Identify 2-3 topics where competitors rank but you don't, OR topics Perplexity flagged as gaps. These are your next content projects.
