# Ahrefs Domain Rating History

Fetches the Domain Rating trend over time for a domain from Ahrefs, showing
historical data points in reverse chronological order with trend analysis.

## References

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

## Inputs

- `domain`: The bare domain to analyze (e.g., `example.com`). Strip `https://`,
  `http://`, and trailing slashes before passing to Ahrefs tools.

## MCP Check

Before proceeding, verify Ahrefs MCP is available:

1. Use ToolSearch with query `+ahrefs`
2. If tools are returned → Ahrefs MCP is available, proceed to Execution
3. If no tools returned → display the Ahrefs MCP error template from
   `references/mcp-degradation.md` and stop

## Execution

**Step 1 — Call Domain Rating History**

Call `mcp__claude_ai_ahrefs__site-explorer-domain-rating-history` with:
- `target`: the bare domain (e.g., `example.com`)

Returns per data point: `date` (ISO 8601), `domain_rating` (0–100), `ahrefs_rank`

**Step 2 — Sort and Analyze**

- Sort data points by date descending (most recent first)
- Calculate overall trend: compare first (oldest) and last (most recent) DR values
  - "DR increased by X points over the last Y months"
  - "DR decreased by X points over the last Y months"
  - "DR stable (±2 points) over the last Y months"

**Step 3 — Flag Significant Changes**

Scan consecutive data points for swings >5 DR points in a single month:
- Mark these as noteworthy events: "Significant DR drop of X points in [month]"
  or "Significant DR gain of X points in [month]"
- These warrant investigation (algorithm update, major link acquisition/loss,
  toxic backlink removal, etc.)

### DR History (Most Recent First)

| 2025-10-01 | 59 | #17,600 |
| 2025-09-01 | 60 | #17,100 |

### Trend Analysis
- **Overall trend:** DR increased by 7 points over the last 6 months (59 → 67)
- **Trajectory:** Upward — consistent growth with minor fluctuations

### Noteworthy Events
- **November 2025:** DR drop of 8 points (60 → 58) — investigate possible
  toxic link removal, algorithm update, or loss of high-DR backlinks
- **January 2026:** DR gain of 7 points (58 → 65) — significant link
  acquisition or algorithmic recovery

### Summary
Current DR 67 represents strong domain authority. The 7-point gain over 6 months
indicates active link building or growing editorial coverage.

### Error — Ahrefs MCP Not Available

If MCP check fails, display the Ahrefs error template from
`references/mcp-degradation.md`:

```
## Ahrefs MCP Not Available

The `/seo ahrefs dr-history` command requires the Ahrefs MCP, which is not
currently connected.

**What you can do:**
- Use `/seo audit <url>` for a full static SEO analysis without live Ahrefs data
- Use `/seo technical <url>` for technical SEO issues without backlink/keyword data

**To connect Ahrefs MCP:**
- Ensure the Ahrefs MCP is registered at user scope in ~/.claude/mcp.json
- Verify with: cat ~/.claude/mcp.json | grep -i ahrefs
- Ahrefs MCP must be registered at user scope (not project scope) to work in subagents
