Google Ads · Conversions dropped

Why did my Google Ads conversions drop?

Google Ads conversions drop either because a conversion action stopped recording, or because impressions, click-through rate or conversion rate fell. Adstudio checks each conversion action first, then traces the drop through impressions, CTR and conversion rate to the campaign and the cause — lost impression share, a disapproval, a bid change or a landing page.

The numbers that matter

What to read first.

Conversions by conversion action: A count that mixes actions drops when one of them goes silent, so this is read first.
Impressions and search impression share: Fewer impressions point to budget, rank or a paused or disapproved entity.
CTR: A falling CTR points to ads, offer or relevance.
Conversion rate: A falling rate with steady clicks points to the landing page, offer or tracking.

The method

How to break it down.

01Split conversions by conversion action and see which one fell.
02Find the campaigns that lost conversions against the previous equal period.
03In those, see whether impressions, CTR or conversion rate fell.
04Match the moment of the drop with the change history: paused ads, edited bids or budgets.

How Adstudio answers it

In the app, or from the AI you already use.

In the Adstudio assistant

The assistant reads conversions per conversion action, compares periods, attributes the drop to campaigns, and reads the Google Ads change history to line up edits with the drop. It names the most likely cause and the one check that would confirm it.

From ChatGPT or Claude, over MCP

Over MCP, your AI can compare impressions, clicks and conversions by campaign and by day for two periods and locate where the drop started. Per-action conversion counts and change history are in the Adstudio app.

Prompts

Copy one and ask.

“Conversions fell last week. Which conversion action dropped, and in which campaigns?”
“Did impressions, CTR or conversion rate cause the drop in conversions on our Search campaigns?”

Limits

What Adstudio will not tell you.

Adstudio cannot see your website; if clicks hold and conversions vanish, it points to tracking or the landing page and, with GA4 connected, reads the property separately.

FAQ

Questions people also ask.

It reads each action's activity. A purchase action that stopped recording while clicks held is reported as a measurement problem first, before any performance reading.
