This article, Adspert explains what you need to take into account when working with Adspert directly after utilising Google Smart-bidding.
How to work with Adspert after using Smart-bidding?
If you have already used smart bidding and you want to try another tool such as Adspert, please be aware of the following points:
Smart-bidding does not show historical data e.g. CPC bids & bid adjustments. This results in a period wherein Adspert needs to gather data before analysing the results from Adspert. This could be done by manually optimising the campaigns for at least 14 days.
When you activate the optimisation in Adspert, you need to turn off the optimisation by Smart bidding or any other auto scripts that you have in Google Ads. Adspert is only able to optimise your campaigns when the bidding strategy is set as” Manual CPC” which means Adspert will take over the steering wheel of the optimisation.
Adspert can not optimise Smart ads campaigns (Shopping and Display), because Google does not provide any data via API and those campaigns are only suited for Smart-bidding.
