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?

How is this different from competitor page compare?

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

Can I diff staging vs production?

Yes, if both URLs are publicly reachable over HTTPS.

Does it include full body text diff?

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

Is AI used for the summary?

No. Structured field compare only.
