To create a shared negative keyword list in Google Ads with Claude or ChatGPT, connect your Google Ads account to PaidSync.ai and ask the assistant to create a shared negative keyword list and fill it, which gives you one list you can reuse across campaigns. First you create the list, then you add terms to it. Applying the list to campaigns is a separate step.
A shared negative keyword list is one set of blocked terms that many campaigns can use, so you fix a bad term once. Claude builds it in two calls and can check what exists first:
list_shared_sets lists the shared sets in the account, including negative keyword lists, so you do not create a second list with the same job.create_negative_keyword_list creates an empty shared negative keyword list with the name you give it.add_to_negative_keyword_list adds keywords to an existing list. A plain string is added as broad match, or you can pass the term with a match type.list_shared_sets only reads your account. create_negative_keyword_list and add_to_negative_keyword_list change it.
| Tool | What it does |
|---|---|
| list_shared_sets | Shows the shared lists already in the account |
| create_negative_keyword_list | Creates the list |
| add_to_negative_keyword_list | Adds terms to the list |
Creating a list does nothing on its own. It only blocks traffic once it is applied to a campaign. A plain string is added as broad match, so give the match type for any term you want tighter control over.
These steps use Claude to create a shared negative keyword list. PaidSync.ai also works in ChatGPT, and the prompts are the same.
Start at paidsync.ai, then link Google Ads through Google's own sign-in screen. No developer token and no Google Cloud project are involved. The login you choose must reach the account where you will create a shared negative keyword list.
Install PaidSync.ai from Claude's connector directory and sign in. Ask "list my Google Ads accounts" and select the account to create a shared negative keyword list in.
Ask for the shared sets in the account. Reusing a list you already have keeps your negatives in one place.
Pick a clear name such as Job Seekers or Free Intent, and ask the assistant to create the list. It returns a preview.
Give the assistant the terms with their match types and ask it to add them to the list. Approve the preview and list the set again.
List the shared sets again and open the new list to check the terms and match types. The list is only active once it is applied to a campaign, which is the next task.
Use these two prompts to create a shared negative keyword list, in this order.
list_shared_sets only reads your account, so the lookup before you create a shared negative keyword list changes nothing.create_negative_keyword_list and add_to_negative_keyword_list run as a preview by default, so you see the change before it is applied.create_negative_keyword_list and add_to_negative_keyword_list run.create_negative_keyword_list and add_to_negative_keyword_list can show a preview but not apply it. Tokens are encrypted at rest.create_negative_keyword_list and add_to_negative_keyword_list are 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 create a shared negative keyword list.
