I thought that I could just wait and reach the 15 conversions threshold necessary for tCPA with time, in a cheap way.
However, I read somewhere that those 15 conversions need to occur within a 30-day timeframe. Is that true? Wouldn’t google just use all my historical data on conversions? Will google only use data from the last 30 days?
The thing is, I could wait for 3-4 months to get to 15-30 conversions, and then turn on smart-bidding. This way I would save a lot of money
On the other hand, if it has to be within a 30-day period, I would need to raise my CPCs and my budgets, and thus spend more money to get the campaign running profitably.
It’s not as if the 15 conversion mark is a magical boundary you have to cross to get into PPC Walhalla…
Smart bidding is going to work better from 15 conversions/month onwards.
But it’ll only work a slightly better than having 14 conversions/month.
And smart bidding will only work marginally better if you reach 16 conversions/month.
I’ve always been told to aim for at least 50 conversions/month to get good results.
But we also have campaigns that don’t hit that 50/month mark every month and yet perform way better than with manual bidding!
Also, I don’t know if it’s applicable to your account, but if you have several smaller campaigns that don’t hit the mark you want, you can group them with portfolio bidding.
