Hi guys, I am curious and confused on look alike audience.
Suppose we a have seed audience which is pulls data from a live site, and we make look alike of that on day 1, and then over 1 week fresh audience keeps on getting added to core custom Audience. My question is will the look alike get auto optimised to changing data or I need to again create fresh look alike to take advantage of the new audiences added.
Cheers and thanks
If the Look-alike audience is based off of a dynamic audience (e.g. a custom audience of people that have made a purchase), it too will be dynamically updated. The audience itself isn't 'optimized' in the sense that - that word is typically used, although it should become more relevant to the product/service you're advertising.
The majority of the optimization happens at the ad set level so as long as you don't tamper too much with the ad set you should be fine.
