Can you explain the problem a little more?

How are you so certain it’s hurting conversions?

Where in your funnel are you passing parameters from and to?

Would encrypting the key/value pair before appending, and then decrypting afterward do the trick?

So i manage advertising for a local garage door service. we using ppc with target geografic. for exsample a customer that looking for services is LOS ANGELES CA see ad that say “garage door repair los angeles” and the url is garagedoorrepair.com/california/?city=los%20angeles. that will change some keyword on the website.

a few times customer booked appointments and then cancel because they were able to play around with the url and it does not good look for them.

So maybe I’m missing something, but it seems like you could have a simple

lookup table that cloaks all that from your user. Your url could be

something garagedoorrepair.com/california/?cpg=1271 . Then inside your

page you could just do a table lookup for Campaign Code (cpg) 1271. In that

table you could have city name, tracking phone number and any other info

that’s parameterized.

The implementation of this, I’m sorry to say, is beyond me but would

certainly be some pretty simple Javascript or something.
