# How do you validate whether an indexation fix actually worked?

> Define validation before implementation.

For a canonical fix, check:

- source HTML;

- rendered HTML if relevant;

- canonical;

- sitemap;

- internal links;

- URL Inspection;

- Google-selected canonical after reprocessing.

For a noindex implementation:

- response;

- robots meta/header;

- crawl accessibility;

- Search Console state over time.

For a migration:

- old URL;

- redirect;

- destination;

- canonical;

- sitemap;

- indexed destination.

Remember that Google reprocessing is not instantaneous. Canonical clusters can take time to be reevaluated.
