Cobiro automatically sets the duration of the ad campaign for a 2 month period. This can be adjusted during the setup process to suit your business goals and requirements.
Cobiro suggests this period as ads on Facebook will eventually suffer from something known as ‘Creative Fatigue’. This term refers to the situation when the same users eventually will start to repeatedly see the ads over and over again. For this reason it is good practice to have the ad running for a specific period of time, enough to be seen but not too much to become repeatedly annoying.
Please remember that you will need to give the ads enough time to get meaningful results. A huge mistake made by many new advertisers is pulling the plug on ads too early.
