Duplicate your existing campaigns

[samiaseo75]

If your current campaigns generate a lot of repeat buyers, then note that the original campaign will be dedicated to them. Just include this in the campaign title.

Then use repeat customer audience lists and gcash data CRM lists as your target audience (There is a new feature in Google that allows you to target only new customers, but I don't use it and prefer lists, except for the Performance Max app).

This will ensure that ads in this campaign only reach those who are on the target lists. If the campaign gains more new customers, then use the CRM and customer audience list as a negative audience/exclusion so that the campaign only shows ads to new customers.

In the new duplicate campaign, do the opposite of the original campaign's settings.

Repeat this process for all applicable campaign types except Performance Max. For Performance Max, this approach works, but it's far from 100%.

Duplicate campaigns (including audience segments). However, for one campaign, you only check the offer for new customers. There is no guarantee that the second campaign will not serve first-time buyers, but from what I have written, this is the closest you can get.
