Technical SEO FAQ · Indexing, Canonicalization & Duplicate Content
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.
