Finds device and location bid modifiers configured on Smart Bidding campaigns — where the algorithm ignores them and they only mislead whoever reads the settings.
by Dmytro Tonkikh·chiliad.io
One table of every campaign's bidding strategy with the two flags that matter: Manual CPC campaigns with enough volume for Smart Bidding, and target-based campaigns too data-starved to learn.
Finds the reallocation hiding in plain sight: efficient campaigns losing volume to budget caps, idle budgets that could fund them, and full budgets funding poor CPAs.
Runs campaigns only inside their date windows — Black Friday starts at 00:00 without anyone staying up, sales end exactly on time, weekend campaigns run only on weekends.
Compares yesterday's average CPC per campaign against its 30-day baseline and alerts on spikes — the earliest visible symptom of a new competitor, broad-match drift, or a bid change gone wrong.
Compares actual spend against your daily budget settings over 1, 7 and 28 days and alerts by email + Google Sheet when Google overdelivers beyond your thresholds.
Compares actual daily spend against the expected pace based on time of day. Logs over- and under-pacing campaigns and can auto-pause overspenders to protect your budget.
Smart Bidding ignores manual device and location bid modifiers (the one exception: device -100% opt-outs) — yet accounts migrated from manual bidding keep carrying them, and they read like active strategy to everyone who opens the settings. Stale Bid Modifier Audit lists every device/location modifier in the account split into two groups: STALE (on Smart Bidding campaigns — remove them) and ACTIVE (on manual campaigns — where they genuinely work and deserve deliberate review instead of fossilizing).

=== Stale Bid Modifier Audit === Campaigns with device/location modifiers: 4 --- STALE - on Smart Bidding campaigns (ignored by the algorithm) --- Generic — Broad: MOBILE -40%, LOCATION +15% Shopping — All Products: TABLET -100% --- ACTIVE - on manual campaigns (these DO work; review deliberately) --- Brand — Exact: MOBILE +10% Email sent to you@example.com
Device -100% still works under Smart Bidding as a hard opt-out and is intentionally not flagged. Campaign-level modifiers only — ad group modifiers are rarer and follow the same logic if you want to extend the query. Removing stale modifiers changes nothing about delivery; it just makes the settings honest.
