Hello Moz! I have been beating my head against the wall for a few hours, and I am starting to get a headache. My question is simple: I am doing some work for a local salon, and we started a PPC campaign recently. It's very important that I get accurate ROI metrics from both our PPC efforts and Yelp advertising program, and the best way to do this is by using custom phone numbers and dynamic number insertion w/ CallRail to track phone calls being made to the salon. I can then cross reference the numbers used to call with the salon POS software to see what they spent, how many appts. they booked, etc. A VERY large portion, the majority in fact, of traffic comes from mobile, and in the past I had a big, fat, beautiful CTA click-to-call button that showed the salon phone number. However, I have found that with dynamic number insertion, and my near non-existent programming skills, it is impossible to have the number dynamically insert into an href image. Sooooo...any ideas on how to do this, or is it just not possible????
