Competitor Gap Analysis

Identify the specific keywords your competitors rank for in the top 20 that your domain does not, ranked by commercial value and realistic capture difficulty.

Prerequisites

• SE Ranking MCP server connected.
• User provides: (a) target domain, (b) 3 to 5 competitor domains (or ask the skill to auto-discover them), (c) market country (default: us), and optionally filters (min volume, max KD, intent).

Process

1. Validate or discover competitors DATA_getDomainCompetitors

   • If the user did not provide competitors, pull the top 5 organic competitors for the target in the target market.
   • Surface the list to the user and ask them to confirm or override before proceeding.
   • Note: the upstream API does not support limit/offset, so this call returns the full set (~60KB for popular domains) and the MCP harness writes it to a file. Read that file path, parse the {data: [...]} JSON, sort by common_keywords desc, and take the top 5.

2. Pull competitor keyword sets DATA_getDomainKeywords

   • For each competitor, pull keywords where they rank in the top 20 of the target country.
   • Save per-competitor lists.

3. Pull target keyword set DATA_getDomainKeywords

   • For the target domain, pull all ranking keywords in the target country (any position).
   • This is the exclusion set.

4. Compute the gap DATA_getDomainKeywordsComparison (cross-check)

   • Keywords ranked by at least one competitor in the top 20 but not ranked by the target domain at all.
   • Use the comparison endpoint as a cross-check.

5. Filter and segment

   • Apply user-specified filters on volume, KD, and intent.
   • Segment by intent: informational, commercial, transactional, navigational.
   • Segment by competition: how many of the N competitors rank for each gap keyword.

6. Score and prioritise

   • Score each gap keyword: traffic potential (volume × CTR model) + intent weighting + inverse KD.
   • Surface the top 50 opportunities with reasoning per keyword.

7. Map to content actions

   • For each top opportunity, recommend: new article, expand existing page, refresh existing page, programmatic template.
   • Flag quick wins: competitors rank with thin content (detected by URL pattern and content-length heuristics).

Output format

Create a folder seo-competitor-gap-analysis-{target-slug}-{YYYYMMDD}/ with:

├── REPORT.md                                (synthesised report — primary deliverable)

Top-level: REPORT.md + gaps.csv. The numbered step files preserve the raw API outputs in evidence/ for reproducibility.

REPORT.md follows this shape:

# Competitor Gap: {target}
Market: {country}
Competitors analysed: {list}

## Summary
- Competitor keywords in top 20: {n}
- Target keywords overall: {n}
- Gap keywords (opportunities): {n}
- Gap traffic potential: ~{n}/mo

## Top 50 opportunities

### Informational intent
| # | Keyword | Volume | KD | Competitors ranking | Action | Score |
|---|---|---|---|---|---|---|
| 1 | {kw} | {n} | {n} | {3 of 5} | New article | {score} |
| 2 | ... | ... | ... | ... | ... | ... |

### Commercial intent
| # | Keyword | Volume | KD | Competitors ranking | Action | Score |
|---|---|---|---|---|---|---|
...

### Transactional intent
...

## Quick wins (top 10)
Keywords where competitors rank in positions 5 to 20 with thin content, low DT, or old dates.

| # | Keyword | Weakest competitor position | Suggested angle |
|---|---|---|---|
| 1 | {kw} | example.com at #14 (2022 article, 800 words) | Fresh, comprehensive guide |

## Recommended next steps
1. Run `content-brief` on the top 3 opportunities to generate writer-ready briefs.
2. Run `keyword-cluster-planner` on the full gap list to build a sequencing plan.
3. Add the gap keywords to an SE Ranking project for rank tracking once content ships.

Tips

• Data API rate limit: 10 requests per second. For large sites, DATA_getDomainKeywords may paginate heavily; set a ceiling (e.g., top 1,000 keywords per domain) unless the user explicitly asks for the full set.
• Call DATA_getCreditBalance before running. A full pass on 10 seeds typically consumes 30–80 credits; 20 seeds can exceed 150.
• The competitors_ranking count is the best signal of realism. Keywords ranked by 4 of 5 competitors are validated opportunities; keywords ranked by only 1 may be noise.
• Do not recommend capturing branded competitor keywords unless the user explicitly asks. Pivoting to compete on "competitor brand review" is a viable strategy but only if the user opts in.
• When many gap keywords cluster around a theme, recommend a hub page plus cluster rather than 50 individual articles.
• Chain this skill with content-brief and keyword-cluster-planner naturally. Mention them in the Recommended next steps section of the output.
