Same content different URL - Google Analytics other Options

[MainstreamMktg]

One of my clients came to me today asking to mirror their current website and host it on a different domain (i.e domain.com and domain.ca). Their reasoning is that there is no actual way to confirm via form entries from their website which visitors are submitting the form from an organic perspective and which ones are submitting the form through an Adwords ad campaign referral they are running (which I have nothing to do with). I know Google Analytics will show you visits to pages on a site and then you can find out which source (organic vs. cpc) they came from, but it won't confirm the source on the actual form entry. So my client feels the only way to find out this information would be to mirror the website so that the separate analytics would validate  their Ad spend.

Does anyone know of any tools that I could use for something like this? I do NOT want to mirror the website as I am fearful of duplicate content and the YEARS of organic SEO work I have put into this website going to waste.

The other element I should mention is the client only wants to have this "mirorred" site up for 2 months.

Any thoughts, suggestions and arguments for a mirorred website are welcomed!

Thanks!

Hi Matt,

We have a fun little trick on our website that involves phone tracking. We use DialogTech to display a different phone number based on which medium the visitor came from. Then, in our forms, there's a hidden field on the form titled "Medium" that reads the phone number in the header. If the phone number displayed is for our Adwords campaign, the hidden field sends "PPC" in the Medium field, and so on for each medium. It can be tricky to implement, but it's a pretty solid way to assign attribution to specific form completions.

This is amazing and EXACTLY what we need! Thank you so much! I will look into it right away!

Awesome, hope you're able to get this setup. Domain-wide duplication would be a tragedy!
