What is SEO Change Diff?

After a redesign, CMS migration, or A/B template change, you need a structured SEO field diff — not a vague “content similarity” score alone.

SEO Change Diff fetches URL A and URL B, extracts title, meta description, canonical, H1/H2 sets, schema types, and link counts, then reports which fields changed. Distinct from competitor compare (which scores who “wins” features). No generative summary.

Use it for pre/post deploy checks, staging vs production, or old vs new URL after a move.

What are common questions about SEO Change Diff?

Can I diff staging vs production?

Yes, if both URLs are publicly reachable over HTTPS.

Is AI used for the summary?

No. Structured field compare only.

Does it include full body text diff?

v1 focuses on SEO fields (title, meta, canonical, headings, schema, link counts).

How is this different from competitor page compare?

Competitor compare scores feature winners. This tool is a field-level change log between two URLs.

What are the key features of SEO Change Diff?

Core SEO fields

Title, meta, canonical, H1/H2, schema types, links.

Similarity metric

Simple overlap score across compared fields.

Change table

Shows A vs B and whether each field changed.

Dual-URL fetch

Compares two public pages in one run.

How do you use SEO Change Diff?

Fix unintended regressions

Restore canonical, title, or heading drift.

Review changed fields

Confirm intentional meta/heading/schema updates.

Enter URL A and URL B

e.g. before/after or staging/production.

When to use competitor compare instead

Use Competitor Page Compare when you want scored feature gaps vs another domain. Use this diff when you care about exact field changes between two of your own URLs.
