What is seo-gsc-opportunities?

A Google Search Console report that finds searches receiving many impressions but few clicks. An impression means a page was shown in Google results, while click-through rate is the share of shown results that people clicked.

Use it to find possible quick wins, improve titles or search-result descriptions, and decide where existing content may need expansion.

It points to pages that already have search visibility but may lose visits because their titles, descriptions, or content do not attract enough clicks.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00072	$0.00984
Opus 5	$0.00036	$0.00492
Sonnet 5	$0.00014	$0.00197
Haiku 4.5	$0.00007	$0.00098

Security

Grade A, and why

seo-gsc-opportunities scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 13d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

GSC Opportunities — High-Impression Low-CTR Finder

@skills/seo/references/mcp-degradation.md @skills/seo/references/gsc-api-reference.md

Finds keywords with significant impressions but low click-through rates — indicating ranking positions where optimization can quickly increase organic traffic without new content creation.

MCP Check

Before calling any GSC tool, verify the MCP is connected:

Use ToolSearch with query +google-search-console
If tools returned — note the actual tool name prefix, proceed to Inputs
If no tools returned — display the GSC MCP error template from references/mcp-degradation.md and stop:

## Google Search Console MCP Not Available

The `/seo gsc opportunities` command requires the GSC MCP, which is not currently connected.

**What you can do:**
- Use `/seo technical <url>` for crawlability and indexability analysis (no live data)
- Use `/seo audit <url>` for a full static SEO audit

**To connect GSC MCP:**
- Install and configure a Google Search Console MCP server (see README for setup)
- Add it to ~/.claude/mcp.json at user scope (NOT project scope)
- Verify GSC property access before running commands (domain vs URL prefix format)
- See references/gsc-api-reference.md for property format details

Inputs

site: The GSC property URL. Accept both formats:
- Domain property: sc-domain:example.com
- URL prefix: https://example.com or https://www.example.com
- If user provides a bare domain (no prefix), call list_sites to identify the correct property format registered in GSC.

Date Calculation

Use Bash to calculate dates (GSC has ~3 day delay):

endDate=$(date -v-3d +%Y-%m-%d)
startDate=$(date -v-31d +%Y-%m-%d)
echo "endDate: $endDate | startDate: $startDate"

Execution

Step 1 — Find keyword opportunities: Call find_keyword_opportunities with:

siteUrl: the site property
startDate: calculated startDate
endDate: calculated endDate
minImpressions: 100 (keywords need at least 100 impressions to matter)
maxCtr: 0.05 (5% CTR threshold — keywords below this are underperforming)
maxPosition: 20 (only keywords ranking in top 20 positions)

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
