Competitor Content Gap Analysis

I'm analyzing competitors in the [YOUR INDUSTRY] space. Here are 3 competitor websites: [URL 1, URL 2, URL 3]. Identify: 1) Content topics they're covering that we're missing, 2) Content formats they're using successfully, 3) Keywords they're ranking for that align with our goals, 4) Gaps in their content we could exploit, 5) Three immediate content opportunities for our brand.
