The fastest way is to look at their numbers first. Check their website traffic, their conversion rate, which means how many visitors are actually taking action, and where those visitors are coming from. If traffic is low, the problem is likely awareness. If traffic is high but nothing is converting, the problem is on the website or in the offer itself. Most issues become obvious once you sit with the data for even thirty minutes. How do you think is the fastest way to identify what is wrong with a client marketing strategy?
