Site analysis & annotations

The Site Analysis group holds the reports you reach for when a question concerns the site as a whole rather than one page or query: does each language version reach its country, how much of your data does Search Console leave out, and did traffic survive a migration. Annotations, which live under Settings, belong with them: they record the events these reports are usually trying to explain.

The reports

• Internationalization: detects the locale of every URL from its folder or subdomain, shows how much of each country's search visibility lands on the version built for it, and compares country domains you have connected.
• Property Sampling: compares the property's exact daily totals with what the query and page breakdowns add up to, so you know how much a query-level analysis can see. The account menu's Sampling impact runs the same check across all your properties.
• Migration Compare: lines up the days before and after a migration date for two properties, two URL prefixes or two URL patterns, matches old pages to new ones (by path or your redirect list) and rates each page and query as recovered, partially recovered, lost or new. It is also in the account menu as Migration.
• Annotations: dated notes for a property or your whole account, shown on the dashboard and analytics charts next to a curated list of Google updates.

When to use which

Before you run them

The site analysis reports fetch a lot of data, so each one waits for you to press its run button. Internationalization and Migration Compare read their own date windows (7 to 31 days, and 14 to 91 days either side of the migration date) rather than the page's date picker; Property Sampling uses the date picker and can also compare the preset ranges in one go. Google's own guidance sits behind the advice in each report: localized versions of pages for hreflang, and site moves with URL changes for migrations.
