The Correct Answer is: Changes to the attribution model AND Changes in competition or seasonality AND Changes to ads
Explanation: Conversion volume in a Google Ads campaign can be influenced by three factors along with conversion delay: changes to the attribution model, alterations in competition or seasonality, and modifications to ads. Any fluctuations in clicks due to seasonality or a change in competition can impact traffic to your website and subsequently conversions. Alterations to your ads such as keyword additions, targeting, ad creatives, and Max CPC may also affect the audience and their likelihood of conversion. Lastly, shifting the attribution model can lead to conversion credits being attributed further into the past, making recent conversion volume appear lower.
