To add audiences to a campaign in Google Ads with Claude or ChatGPT, connect your Google Ads account to PaidSync.ai and ask the assistant to add an audience to a campaign, which lets Google use that audience for bidding or to limit who sees the ads. The default is observation, which does not narrow your reach. Restricting a campaign to an audience needs your explicit say-so, and every change returns as a preview.
Audiences let you bid differently for known groups, such as past visitors, or show ads only to them. Claude reads the available lists, then attaches one:
list_user_lists lists the remarketing and customer match lists in the account, including website visitors and app users.list_audiences lists the audience criteria already attached to campaigns, with an optional campaign filter.add_audience_targeting adds an audience to a campaign. The default is OBSERVE, and TARGET, which restricts reach to that audience, needs an explicit confirmation flag.list_user_lists and list_audiences only read your account. add_audience_targeting changes it.
| Tool | What it does |
|---|---|
| list_user_lists | Shows the audiences you can attach |
| list_audiences | Shows what a campaign already targets |
| add_audience_targeting | Attaches the audience to the campaign |
The two modes behave very differently. Observe lets you see how an audience performs and adjust the bid from 0.1 to 10 without cutting reach. Target limits the campaign to that audience only, which on Search can shrink traffic sharply, so use it on purpose.
These steps use Claude to add audiences to a campaign. 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 add audiences to a campaign.
Open Claude's connector directory, add PaidSync.ai and sign in. Ask "list my Google Ads accounts", then pick the account where you will add audiences to a campaign.
Ask for the user lists in the account and note the one you want. Check how many people it holds before you rely on it.
Tell the assistant plainly whether to observe or to restrict. If you do not say, it defaults to observe.
Ask it to run add_audience_targeting. Read the preview, approve it, then list the campaign audiences to see it attached.
Check the campaign audiences list, then compare conversion rate for the audience against the rest after a few weeks. A strong audience can earn a bid modifier above 1.
Use these two prompts to add audiences to a campaign, in this order.
list_user_lists and list_audiences only read your account, so the lookup before you add audiences to a campaign changes nothing.add_audience_targeting runs as a preview by default, so you see the change before it is applied.add_audience_targeting runs.add_audience_targeting can show a preview but not apply it. Tokens are encrypted at rest.add_audience_targeting is applied, the change is logged, on a best-effort basis, with a before-and-after result.Every Google Ads tool PaidSync.ai offers is on the Google Ads MCP server page, including the tools used to add audiences to a campaign.
In Google Ads, open the campaign, go to audiences and add a segment, choosing observation or targeting. With PaidSync.ai, ask Claude or ChatGPT to attach the audience and it previews the change first.
Observe records how the audience performs and lets you bid differently without limiting reach. Target restricts the campaign to the audience only.
Yes. PaidSync.ai connects Google Ads to ChatGPT and to Claude, and the same tools run in both, so you can ask it to add audiences to a campaign the same way you would in Claude.
