What Content Gap Analysis Finds

Four types of gaps:

  1. Topic gaps — subjects your competitors cover that you don't have pages for
  2. Keyword gaps — queries your competitors rank for that you don't
  3. Format gaps — content types competitors have (video, tools, calculators) that you lack
  4. PAA gaps — specific PAA questions competitors answer that you don't

Step 1: Competitive Set Definition

Define 3-5 real competitors (NOT directories, NOT aggregators like Yelp — only businesses competing directly for the same customers). Exclude:

  • Directory listings (Yelp, Angi, HomeAdvisor)
  • Aggregators (local.com, manta.com)
  • Reddit, Quora, news sites

Competitor selection criteria:

  • Serves the same service area
  • Targets the same primary services
  • Business model similar (not franchise vs. local independent unless that's the comparison)

Step 2: Competitor Content Inventory

For each competitor, catalog:

  • All pages in their sitemap (via sitemap-analyzer)
  • All ranking keywords at positions 1-30 (via dataforseo-keywords Keywords for Site endpoint)
  • All PAA questions their top pages answer (extract H3s from top 10 pages)

Output: a master list of content pieces per competitor.

Step 3: Topic Gap Matrix

Build a matrix: competitor content vs. your content.

| Topic / Content Piece | Competitor 1 | Competitor 2 | Competitor 3 | You | |----------------------|-------------|-------------|-------------|-----| | Roof replacement guide | ✓ | ✓ | ✓ | ✗ | | Storm damage insurance | ✓ | ✓ | ✗ | ✗ | | Roof types comparison | ✓ | ✗ | ✗ | ✗ |

Priority:

  • Topic in 3/3 competitors + not in yours = CRITICAL gap (the market expects this)
  • Topic in 2/3 competitors + not in yours = HIGH priority
  • Topic in 1/3 competitors + not in yours = MEDIUM priority (may be a niche opportunity)

Step 4: Keyword Gap Analysis

Use dataforseo-keywords Keywords for Site endpoint to extract:

  • All keywords competitor 1 ranks for (positions 1-30)
  • All keywords competitor 2 ranks for (positions 1-30)
  • All keywords YOU rank for (positions 1-30)

Find: (competitor 1 ∪ competitor 2 ∪ competitor 3) MINUS your keywords = gap list.

Filter gap list by:

  • Volume > 50/month
  • Intent: commercial or transactional (buyer keywords first)
  • Not branded for a competitor

Step 5: Format Gap Analysis

Review the content FORMAT of top-ranking competitor pages:

  • Do they have interactive tools (roofing calculators, cost estimators)?
  • Do they have video content embedded?
  • Do they have comparison tables you don't?
  • Do they have downloadable guides or checklists?

Format gaps are harder to address but create strong differentiation. A competitor with a "Roof Replacement Cost Calculator" holds that query category even if your text content is better.

Step 6: PAA Gap Analysis

For each service you offer, query Google and extract all Level 1-2 PAA questions. Cross-reference with your content:

  • Questions answered on competitor pages but NOT answered anywhere on your site = PAA gap
  • Questions with no strong source in your niche = first-mover opportunity

Prioritization and Roadmap

Output: prioritized content opportunity list

| Opportunity | Type | Priority | Est. Volume | Quick Win? | |-------------|------|----------|------------|------------| | Roof replacement guide | Topic | Critical | 500/mo | No (needs full pillar) | | "How much does storm damage repair cost?" | PAA | High | 200/mo | Yes (600-word PAA post) | | Metal vs asphalt comparison | Topic | Medium | 150/mo | Yes (1,500 word comparison) |

Quick wins (PAA posts, FAQ additions): execute in weeks 1-4. Full topic builds (pillar + cluster): schedule for months 1-3.
