What Is Keyword Gap Analysis?
Keyword gap analysis is the process of comparing your website’s keyword rankings with those of your competitors to find valuable search terms they rank for that you don’t, or where they outrank you.
Keyword Gap Analysis Definition
Keyword gap analysis uses ranking data from SEO tools to compare the keywords that bring traffic to your site against those that bring traffic to competing sites. It typically sorts keywords into groups such as missing (competitors rank, you don’t), weak (you rank lower than competitors), and untapped (only one competitor ranks). These groups reveal targeting opportunities and inform your content and optimization priorities.
Why Keyword Gap Analysis Matters
Your competitors’ rankings are a map of proven search demand in your market. Keyword gap analysis uses that map to show where you’re missing traffic and where small improvements could move you ahead.
It also helps prioritize. Instead of researching keywords from scratch, you can focus on terms that already bring customers to businesses like yours.
Without keyword gap analysis, a business may:
“Target keywords based on assumptions while competitors quietly capture high-intent searches.”
With keyword gap analysis, a business can:
“See exactly which valuable keywords competitors own and build a plan to compete for them.”
The goal is to find the most valuable search terms you’re leaving on the table.

Sort keywords into missing, weak, strong, and untapped groups to see where opportunities lie.
4. Filter for Relevance and Value
Remove irrelevant terms and focus on keywords with clear business intent, realistic difficulty, and meaningful volume.

See Rank Rise SEO ServicesExample of Keyword Gap Analysis
Imagine an accounting firm compares its site with three regional competitors. The analysis might reveal:
Missing: “outsourced bookkeeping for small business”
Weak: “CPA near me,” where the firm ranks on page two
Untapped: “R&D tax credit consultant,” which only one competitor targets
Strong: “nonprofit audit services,” where the firm leads
The firm can then create a bookkeeping page, strengthen its local signals, evaluate the R&D credit opportunity, and protect its nonprofit rankings.
