SEO Changelog Tool Guide
"Why did rankings suddenly drop?" "When did we last change the title?" Use SEO changelog to record every modification, so teams clearly know "who, when, what changed, why, and impact."
1) Why SEO Changelog?
- Track SEO History: Record all SEO-impacting changes (title, description, schema, canonical, URL structure, etc.) without digging through git logs.
- Before/After Comparison: Clearly see "what it was before" → "what it became" → "why the change."
- Team Collaboration: Documentation that marketing, SEO, and dev teams can all understand—no technical background required.
- Attribution Analysis: When rankings/traffic change, quickly identify "which change caused it" to decide whether to revert or continue optimizing.
2) What Should Changelog Record?
Required Fields
- Date (when change went live)
- Change Type (title, description, schema, canonical, URL, content, technical)
- Scope (single page, multiple pages, site-wide)
- Change Details (Before → After)
- Reason (why the change)
Optional Fields
- Owner (who executed)
- Ticket/Issue Number (for traceability)
- Expected Impact (predicted improvement/neutral/potential decline)
- Actual Impact (2-4 week observation results, record here)
- Rollback Status (whether reverted, when reverted)
3) Workflow: 3 Recording Methods
Method 1: Manual Recording (Small Teams)
- Open SEO Changelog Tool, fill in change information.
- Tool auto-generates Markdown changelog, copy to
CHANGELOG.mdor Notion/Confluence. - After each deployment, team members manually update changelog.
Method 2: CI/CD Auto-Recording (Recommended)
- Add SEO diff detection step in CI/CD pipeline.
- Before each deployment, compare SEO element differences between production and staging.
- If differences exist, auto-generate changelog entry and commit to repo.
- Optional: auto-send Slack/Email notification to team.
Method 3: Periodic Manual Comparison (No CI/CD)
- Every Friday, use tool to fetch all pages' SEO elements.
- Compare with last week's snapshot to find differences.
- Manually record meaningful changes (ignore automated dates/dynamic content).
4) Markdown Changelog Example

plaintext
Example: Evaluate Title Change Impact
1. Change Date: 2025-01-15
2. Wait 2-4 weeks (SEO effects take time)
3. Compare dates in GSC:
- Before: 2025-01-01 ~ 2025-01-14 (14 days)
- After: 2025-01-16 ~ 2025-01-29 (14 days)
4. Observe metrics:
- Clicks (traffic)
- Impressions (visibility)
- CTR (click-through rate)
- Average Position (ranking)
5. Record results in changelog's "Actual Impact" field
If impact is positive → Continue optimizing other pages
If impact is negative → Revert change, record in Rollback field6) CI/CD Automation Example (GitHub Actions)
