Every check writes a report. The newest of each kind is on the business's Reports tab and on the Reports page; older ones stay in your data store (Settings → Export everything).
Each row shows the date it was written and how old it is. "Out of date" appears past 45 days: some reports (Keywords, GBP) are only refreshed by the full check, so an old one is normal, not broken.
The Monthly summary is the one written for the business owner: plain language, what improved, what's next. It's the report you send on. With Google Drive connected it also arrives as a Google Doc in the business's folder, ready to share.
Reports are written by AI from the data collected. Read one before you send it: it's a strong draft, not a signed-off document.
