Like most marketing strategies involving Google, you can’t expect results to happen overnight. While you can start generating clicks and impressions from day one, it takes time to optimise your campaigns for conversions and ROI.
Typically, you might start to see a trend in results after about one to three months. This can vary a lot depending on your business, your current brand position, your competition and industry, and what kind of goal you’re aiming for.
Even after three months, the best display advertising services will take the results and finetune the strategy to continue to improve conversion rates and ROI.
