Thankfully I’m working with a conscientious marketing firm and our client is diligent and well meaning, so it’s easy to avoid the pitfalls, but naively following many integration walkthroughs could have you sending entire form content to Google (or others). I’m sure that’s one of the reason Google explicitly says “don’t put us on your EMR pages” (paraphrased).
Just using the same massive aggregator as your metrics provider is where it gets wrong.
Most people aren’t going to be browsing the Betty Ford clinic for fun. They’re looking for something specific. That’s juicy for analytics. I’m glad I don’t have to deal with that challenge.
(Conversion matching quality isn’t a fun challenge either. We’ve landed at “the practice will have to do that themselves to avoid the privacy obstacles”.)
