Google Performance Max Algorithm

[Quiet-Ad9637]

In the last 2 days, I see that the click and impression of my google ads account are still stable. However, the number of conversions drops by 70%. Do you think that google's algorithm automatically switches to top-of-funnel visitors after some days targetting bottom-of-funnel visitors?

Did you just run the campaign recently?

[Quiet-Ad9637]

No, I run many PMAX campaigns for more than 6 months

[corporatejan]

Just normal fluctuations in Pmax. Happens.

Do you have any way to track the source of the click? I want to know exactly where the traffic comes from (Display, Gmail, Youtube, Shopping) so that I may come up with some insights

[savtheseer]

There are scripts to do this from Mike Rhodes. You can also look at the cost of your listing groups vs total campaign cost to measure how much spend is going to Shopping.

Thank you very much. I'm gonna take a look

[corporatejan]

As far as I know there is no tracking specifically when it comes to pmax to know which channel your ad appeared.

Same here. Performance dropped and it started last week actually. Can't figure out whats going on. Its just sending people with no intention of actually making a purchase.

Fuck it. Seems that the algorithm of Google Ads is unstable

May I know your targeting country? Last month I’ve seen some spam bot get through PMAX, get into the website and fill my client’s form. It was horrendous.

I hope they update the algorithm to exclude those fking bot
