First sync and historical backfill explained
First GSC sync unlocks a recent data window quickly; historical backfill continues in the background afterward.
RankWatch prioritizes a recent Search Console window so Overview becomes usable quickly, then backfills older days.
What it is
First sync — initial import after linking a property (short recent window).
Historical backfill — continued import of older GSC days until the retention window is filled or Google pagination ends.
What to expect
- Dashboards may look “incomplete” for history until backfill catches up.
- Changing property restarts sync for the new property.
- Google API quotas/delays can slow backfill; Rankings tracking is independent.
Where to find it
Project Search Console → Settings (connection status) and Overview as data arrives.
