To change a bidding strategy in Google Ads with Claude or ChatGPT, connect your Google Ads account to PaidSync.ai and ask the assistant to change the bidding strategy of a campaign, which switches how Google sets your bids. If you pick a target CPA or a target ROAS strategy, you must also give the target. PaidSync.ai previews the change before it is applied.
The bidding strategy tells Google how to set bids. Claude can read the current setup, then switch it with one write tool:
get_campaign_details returns the campaign's current bidding strategy, budget and a metrics snapshot.list_bidding_strategies lists portfolio bidding strategies with their type, status and results, in case you want a shared strategy.update_campaign updates campaign settings, including the bidding strategy, target CPA and target ROAS.get_campaign_details and list_bidding_strategies only read your account. update_campaign changes it.
| Tool | What it does |
|---|---|
| get_campaign_details | Shows the strategy you are starting from |
| list_bidding_strategies | Lists shared strategies you could attach |
| update_campaign | Writes the new strategy and target to the campaign |
The strategy name is a strict list that includes manual CPC, maximize clicks, maximize conversions, maximize conversion value, target CPA, target ROAS and target impression share. Switching to target CPA or target ROAS fails without a target value.
These steps use Claude to change a bidding strategy. PaidSync.ai also works in ChatGPT, and the prompts are the same.
Create a free account at paidsync.ai and approve Google Ads on Google's own sign-in screen. You do not need a developer token or a Google Cloud project, only a login with access to the account where you will change a bidding strategy.
Open Claude's connector directory, add PaidSync.ai and sign in. Ask "list my Google Ads accounts", then pick the account where you will change a bidding strategy.
Ask for the campaign details and note the strategy, the budget and the last 30 days of conversions.
Tell the assistant which strategy to move to and, for target CPA or target ROAS, the target. Smart bidding needs conversion data to work well.
Ask it to run update_campaign. Check the preview shows the old and new strategy, then approve it and read the details back.
Read the campaign details again and check the strategy and target. Give the new strategy time to learn before you judge it, and avoid changing the budget at the same moment.
Use these two prompts to change a bidding strategy, in this order.
