Content Gap

Content gap analysis uses multiple inputs to identify uncovered topics^[1]. Competitive SERP analysis: pick 10-20 important queries in your space and identify which pages rank that are on competitor sites, not yours — each is a gap. Keyword gap tools (Ahrefs Content Gap, Semrush Keyword Gap) systematically compare your ranking keyword profile against competitors'. Customer and sales research: the questions your sales team hears repeatedly, the objections customers raise, and the support tickets that come in most often all reveal content gaps — these are often the highest-converting pieces to create. Search Console Queries report: look for queries where your site has impressions but low clicks and no ranking page that directly matches the query — these are gaps in your own site's coverage.

Not all gaps deserve equal attention^[1][2]. Prioritize by: (1) Business impact — gaps in topics directly related to your product or service have higher conversion potential than tangential topics. (2) Search volume and keyword difficulty — high volume, moderate difficulty gaps offer the best ROI. (3) Audience alignment — does filling this gap serve your target buyer, or an unrelated audience? (4) Content production cost — some gaps require expensive research or expert interviews; others can be filled quickly by expanding an existing page. (5) Topical authority — filling gaps within your existing expertise areas strengthens authority faster than starting entirely new topic clusters. Score gaps on these dimensions and create a prioritized content roadmap rather than trying to fill all gaps at once.

A keyword gap is a specific search term competitors rank for that you don't; a content gap is a topic your audience cares about that isn't adequately addressed on your site^[2]. The distinction matters because content gaps may not surface in keyword tools if the topic is searched conversationally or across many specific queries rather than one clear head term. A content gap might be 'how to measure content ROI' — an important topic for your B2B audience — that appears as dozens of different long-tail keywords in tools rather than one obvious gap keyword. Additionally, content gaps can exist within your own site: you mention a topic in passing across several posts but have no dedicated page that fully addresses it. These internal gaps are often the fastest to fill by creating a dedicated pillar page and updating existing posts to link to it.
