PMax structure question

Hi everyone,

I recently joined the group and already see so much value here. Big thanks to Chris for creating this community.

I’d really appreciate your advice on my PMax setup.

I’ve been running a PMax campaign since October, so it has gathered solid historical data. Recently, I had to scale the budget back to €50/day. Since then, my store has grown a lot and I now have around 700 - 800 products (far more than when I first launched the campaign). With the lower budget, I’ve segmented products into types and currently run only a few, but there are still many products included overall.

I’m wondering what the best move would be:

Should I create a separate PMax campaign with only my top ~60 best-selling products and focus the €50/day there?

Or should I keep the existing campaign and simply refine it using custom tags to include only those best sellers?

Or do you have any other suggestions on how you would approach this situation?

Thank you in advance 🙏
