So i have an old pmax campaign with a lot of data in it. Around 1 year old, when i dig in, there is around 350 products out of the total 20k that are producing the conversions. This campaign is also limited by budget and is on a very small budget of £100 a day. Previously it had daily budgets of around £500 but this was scaled down since some tracking issues threw out all the reporting and so we had to scale the ad down while tracking was fixed. So my questions now is, would you A - Increase the budget since the roas is around 2.5 ( more than breakeven ), OR would you pause all the non performing products, and let the current budget go towards the 350 converting products. Or C, do both? Also the current settings for the campaign are Max Conversion Value with no target ROAS. In the past when this campaign was doing really well, we had a troas in the settings of 330%, and campaign was delivering close to 400%. But when we scaled the campaign down due to the tracking issue, we took the troas goal away to allow the campaign to start again.
