Competitor Keyword Analysis: Finding Search Terms That Drive Competitor Traffic

Home / Everything About / Everything About Analytics / Competitor Keyword Analysis: Finding Search Terms That Drive Competitor Traffic

Competitor keyword analysis reveals which search terms drive traffic to competitors. If a competitor ranks for "how to build a website" (5000 monthly searches) but you do not, that is a gap. Understanding their keywords tells you where customer demand exists and where competitors are strong.

Why competitor keywords matter

Search demand is fixed. There are only so many people searching for "website builder" each month. If competitor A gets 70% of that traffic, you get 20%, and competitor C gets 10%, you know the market size and your competitive position. Understanding competitor keywords reveals where customer demand is highest.

Finding competitor keywords

Step 1: Get a list of competitor keywords. Use Ahrefs, SEMrush, or Moz. Enter competitor domain. Export all keywords they rank for (positions 1-100).

Step 2: Filter for valuable keywords. Sort by search volume. Keywords with 100+ monthly searches are worth targeting. Keywords with 10 searches are noise.

Step 3: Identify which you don't rank for. Cross-reference with your own keyword list. The differences are your gaps.

Step 4: Assess difficulty. Ranking for a keyword where the competitor ranks #1 is hard. Ranking where they rank #8-10 is easier.

Step 5: Prioritize by opportunity score. Score each gap by combining volume, difficulty, and relevance (does it fit your business?). A keyword with 500 searches, difficulty 20, and high relevance scores higher than 2000 searches with difficulty 70. Focus first on the highest-scoring gaps.

Three types of competitor keyword gaps

High-volume gaps: competitor ranks for keyword with 1000+ monthly searches, you don't rank. These are valuable. Priority: fill the gap with new content.

Easy-rank gaps: competitor ranks position 8-15, you don't rank at all. Lower volume (100-500 searches) but achievable. With good content and links, you can rank higher than them.

Niche gaps: competitor ranks for specific long-tail keywords (50-100 searches). Low volume individually but valuable in aggregate. Create content covering these long-tails and your total traffic grows.

Using competitor keywords for strategy

Content roadmap: create content for keywords competitors rank for but you don't. Prioritize by volume and competition difficulty.

Outrank strategy: for keywords where competitor ranks #5 but content is weak, create better content. Better content + more links = higher ranking.

Semantic coverage: if competitor covers keyword "email marketing for real estate" and you don't, but you do cover "real estate marketing", you are missing the "email" angle. Expand your content to cover this angle.

Monitor keyword ranking changes: track whether your competitor is gaining or losing keywords month-to-month. Sudden keyword loss signals an algorithm update or SEO problem on their site. You might rank for those keywords faster because they lost ground.

Build topic clusters around gaps: don't just create one page for a competitor's keyword. Create a cluster of related pages. If competitor ranks for "best email marketing software", create pages for "email marketing tools for startups", "email marketing for nonprofits", "email automation", etc. Clustering gives you more coverage and makes your site the authority.
