To run an A/B test experiment in Google Ads with Claude or ChatGPT, connect your Google Ads account to PaidSync.ai and ask the assistant to create an experiment on a campaign, which splits traffic between the original and a variant so you can compare them. You choose the control campaign, the split and the dates. Starting, applying or deleting an experiment needs your confirmation.

Which Tools Do the Work

A campaign experiment tests one change against the original on a share of traffic. Three tools cover its life:

list_experiments only reads your account. create_experiment and update_experiment change it.

How the Workflow Is Built

ToolWhat it does
create_experimentSets up the experiment
list_experimentsShows experiments and their status
update_experimentStarts, graduates or removes the experiment

Test one change at a time, or you will not know what moved the result. Run it long enough to cover your conversion lag. Graduating applies the experiment arm to the original, so confirm only once the data is clear.

How to Run an A/B Test Experiment in Google Ads With Claude in 5 Steps

These steps use Claude to run an A/B test experiment. PaidSync.ai also works in ChatGPT, and the prompts are the same.

1

Connect Google Ads to PaidSync.ai

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 run an A/B test experiment.

2

Add PaidSync.ai to Claude

Open Claude's connector directory, add PaidSync.ai and sign in. Ask "list my Google Ads accounts", then pick the account where you will run an A/B test experiment.

3

Define the test

Write down the single change you want to test, such as a new bidding strategy, and the campaign that will act as control.

4

Create it

Ask the assistant to create the experiment with your split and dates. It returns a preview and needs your confirmation.

5

Start, judge and graduate

Ask it to start the experiment. When the data is in, compare results and either graduate the winner or remove the experiment.

How to Check the Result

List the experiments to see the status, and compare both arms on cost per conversion after the test window. Do not graduate on a few days of data.

Use these two prompts to run an A/B test experiment, in this order.

"Create a 50/50 search experiment called New Bidding Test on my campaign Lead Gen Search."
Comes back as a preview and needs your confirmation.
"List my experiments with their status and dates."
Reads your account and changes nothing.

A connected Google Ads account, the control campaign, a name, and optionally a traffic split and dates.
