Top Moves This Period
The March 2021 cycle brought the usual mix of ranking updates, AI Overviews expansions, and quieter algorithm shifts. We only surface items that changed a real client site.
What to Change This Week
Nothing on this list is emergency work — but pushing it now will keep you ahead when the next quarter's changes stack.
- Re-check canonicals on paginated archives.
- Refresh JSON-LD Article authors for E-E-A-T.
- Audit AI-Overview candidate pages against the current answer format.
What We're Watching Next
Signal quality across AI surfaces is still the dominant story. Model-specific citation patterns are stabilizing enough to design for.

Paired module: SEO Error Monitor
A rolling scan of indexability, canonical drift, meta length, duplicate H1s, image weight, mixed content and schema validity — with severity and one-click fixes. Errors are cheap to introduce (a theme update, a plugin conflict) and expensive to find without a monitor watching every publish.
- Enable Error Monitor in SEO Features
- Set severity thresholds per environment
- Route P1 issues to Slack/Email via the reports channel
- Approve suggested fixes in bulk or per-URL
Do I need to change my strategy based on March 2021?
Rarely. Monthly recaps are for calibration, not pivots. Pivots come from your own analytics.
Where do you source this?
Google's official communications, Search Central posts, first-party AI-surface changelogs, and our own client dashboards.
Can I re-run onboarding later?
Yes — Onboarding is a persistent module you can rerun after site changes, and each run keeps a history.
Will the monitor false-alarm on staging?
Environment awareness is built in — staging URLs and noindex pages are excluded by default and severity is downgraded accordingly.
