| Performance > Search results | Daily, then weekly summary | Compare clicks, impressions, CTR, and average position against the pre-launch baseline. Split brand and non-brand queries. | Investigate if non-brand impressions drop 20 percent day over day, or 30 percent week over week. |
| Performance > Pages | Daily | Sort by click loss and impression loss. Mark P0 URLs that had traffic before launch and now dropped or disappeared. | Escalate if a P0 page loses 30 percent of impressions or no longer appears in the top page export. |
| Performance > Countries and devices | Every 2 days | Check whether the drop is isolated to one country, mobile, desktop, or a template used by one device experience. | Investigate if mobile drops while desktop is stable, or one target country loses visibility while others do not. |
| Indexing > Pages | Daily | Track indexed count, not indexed count, and reason changes. Export new noindex, duplicate, soft 404, redirect, and crawled not indexed rows. | Escalate if indexed pages fall more than 10 percent, or if excluded priority URLs share the same reason. |
| Indexing > Sitemaps | Daily for week 1, then twice weekly | Confirm the submitted sitemap is read, current, and close to the expected URL count. Record last read date and discovered URLs. | Resubmit only when the sitemap is fixed and GSC evidence shows stale, missing, or unprocessed sitemap state. |
| Settings > Crawl stats | Daily for week 1, then twice weekly | Watch crawl volume, response codes, file type distribution, and spikes in 404, 5xx, redirect, or robots-blocked responses. | Escalate if Googlebot is spending crawl on redirects, 404s, 5xx responses, or old URL patterns. |
| Security and Manual Actions | Daily for week 1, then weekly | Check Manual actions and Security issues even when the migration looked technical. Record a screenshot either way. | Any manual action or security issue is a P0 incident and should stop routine monitoring until resolved. |
| URL Inspection | 10 to 20 URLs per day | Inspect rotating P0 URLs. Record availability, indexing state, user-declared canonical, Google-selected canonical, sitemap discovery, and last crawl. | Request indexing only after the live test confirms the fixed page is indexable, canonicalized correctly, and in the sitemap. |
