What a change set is
A change set is one proposed website change, treated as a document rather than an edit. It starts as a request in plain language, becomes code written in a sandbox on a branch, and produces a preview link on the real content. The change does not touch the live site while it is a change set.
What happens to it
Before approval, the change runs through the quality gates: the SEO contract, build checks, link checks and the tests that cover the page. The result is a preview the owner can open and a report of what passed. Approval deploys it; rejection archives it. After deploy, the change is measured over a window so the next decision rests on evidence rather than memory.
What it does not control
A change set does not decide that a change is a good idea. It makes the proposal inspectable, reversible and attributable: one request, one diff, one approval, one deploy, one rollback point. Search outcomes still depend on factors outside the site, and no set of gates changes that.
Why the shape matters
The product’s change-set flow is the same for a title fix and for a migration: request, sandbox, preview, gates, approval, deploy, measure, keep or roll back. The shape is deliberately boring. A site owner should be able to predict what happens to a change before asking for it.

- SEO contract
An SEO contract is the fixed list of search facts a migration must keep — URLs, titles, canonicals, schema, sitemap and robots — checked as a pass-or-fail gate.
- Redirect map
A redirect map records the decision for every legacy URL: keep the path, redirect it, remove it or flag it for review. It is tested before cutover.
- Canonical URL
A canonical URL is the address a page declares as its true location with rel=canonical. It consolidates duplicates and must match the sitemap and hreflang.
