So, after you optimized bids per source, you might want to change the general price on the campaign at one point.
Let’s give an example: Your campaign is profitable, and you see the potential in all the sources, so you want to raise a bid for your campaign.
If your campaign has a bid of $0.1 and you raise it up to $0.2, all the sources you have previously modified will be modified accordingly by the platform itself.
For example, if we have a source that has been raised for 33%, like in this example, that source will have a 33% higher price than your general bid in each case.
So, the new price of this source will be $0.266.
If you’re wondering how let’s show it:
Campaign bid – $0.1 Source “3” bid + 33% = $0.1 + 33% = $0,133
Campaign bid – $0.2 // Source “3” + 33% = $0.2 + 33% = $0.266
All your changes on each separate source will be implemented even after you change a general bid.
This is why we are using relative values (%) to change the prices per source. This way, source 3 (from this example) will remain the source with the highest bid.
A general campaign bid is always taken as a reference point on which certain percentages are added accordingly to each separate source.
