# GSC New Keywords — New Ranking Discovery

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

Identifies queries that are newly appearing in Google Search results — either
completely new (no prior impressions) or newly clicking through (no prior clicks).
Sorts by current clicks to surface the most impactful new rankings first.

## MCP Check

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

1. Use ToolSearch with query `+google-search-console`
2. If tools returned — note the actual tool name prefix, proceed to Inputs
3. 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 new-keywords` 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 the two comparison periods (GSC has ~3 day delay):

```bash
currentEnd=$(date -v-3d +%Y-%m-%d)
currentStart=$(date -v-31d +%Y-%m-%d)
previousEnd=$(date -v-31d +%Y-%m-%d)
previousStart=$(date -v-59d +%Y-%m-%d)
echo "Current: $currentStart to $currentEnd | Previous: $previousStart to $previousEnd"
```

## Execution

**Call `compare_performance` with 28-day window:**
- `siteUrl`: the site property
- `currentStartDate`: currentStart
- `currentEndDate`: currentEnd
- `previousStartDate`: previousStart
- `previousEndDate`: previousEnd
- `dimension`: `"query"`
- `limit`: 1000

**Post-processing — identify new keywords:**
Filter results to rows where EITHER condition is true:
1. Previous period had 0 clicks AND current period has > 0 clicks
   (truly new click-generating keywords)
2. Previous period had 0 impressions AND current period has > 0 impressions
   (just started appearing in search results, may not click yet)

Label each result by type:
- "New Clicks" — was showing but not clicking before, now getting clicks
- "New Ranking" — was not appearing at all, now showing in search results

Sort by current clicks descending (most impactful new keywords first).

**Emerging topic detection:**
After filtering, look for common words or phrases across the new keywords.
If 3 or more new keywords share a common root word or topic cluster, note it as
an emerging content opportunity.

CTR display rule: API returns CTR as decimal — multiply by 100 for display.

## Output Format

```
## GSC New Keywords: [site property]
**Current Period:** [currentStart] to [currentEnd]
**Previous Period:** [previousStart] to [previousEnd]
**New keywords found:** [count]

### Newly Ranking Keywords
| Type | Query | Current Clicks | Current Impressions | CTR | Position |
|------|-------|---------------|---------------------|-----|----------|
| New Clicks | [query] | [n] | [n] | [X.XX%] | [X.X] |
| New Ranking | [query] | [n] | [n] | [X.XX%] | [X.X] |
...

### Emerging Topics
[If 3+ new keywords share a topic cluster:]
- **"[topic]" cluster:** [n] new keywords (e.g. "[kw1]", "[kw2]", "[kw3]")
  Opportunity: Consider creating or expanding content targeting this topic area.

[If no clear topic clusters:]
No clear topic clusters detected among new keywords.

### Summary
| Metric | Value |
|--------|-------|
| New click-generating keywords | [n] |
| New ranking keywords (impressions only) | [n] |
| Total new keywords | [n] |
| Top new keyword by clicks | "[query]" ([n] clicks) |
```

If no new keywords found, report: "No new keywords detected. All queries in the
current period also appeared in the previous period."
