How do I fix a "Low Bid" indicator?

A Low Bid indicator means your campaign is spending its budget more slowly than its elapsed flight time (more than 10% behind schedule) — see What does the "Bid Indicator" mean? for how it's calculated.

To fix it:

1. Raise your CPM or CPC bid. This is the most direct fix — a higher bid wins more auctions, increasing delivery speed.
2. Widen targeting if it's very narrow (geos, devices, sources) — limited inventory can cause slow pacing even with a competitive bid.
3. Switch budget pacing to ASAP (if currently on EVEN) — ASAP pacing spends toward your daily budget as fast as possible rather than spreading it evenly across 24 hours.
4. Check your balance — a low balance won't cause a Low Bid indicator directly, but it will stop delivery outright once it hits $0, which can look similar at a glance.

After adjusting your bid, allow a few minutes for pacing to catch up before making further changes.
