Global Forms and Landing Pages

Hi All,
I know many of you are at Marketo Nation this week, I wish I could be there as well. Hopefully, someone in the community can help me out.

Current situation: We use local forms for each of our programs that we use to acquire leads. We have a strong paid media strategy leveraging channels like Google Adwords to drive a high volume of leads.

In our current method we are able to get almost a 1:1 attribution on capture acquisition program and program success from our campaigns. This methodology is working very well for current strategy. However, we're looking at making a change in our methodology to meet a larger scale approach to our lead gen activities.

Here's the current methodology example in screenshots. This works well when you have a handful of programs per channel (i.e. Adwords, etc..), but we're now moving to an approach were we can have 50+ programs per channel with each program having a multitude of landing pages.

Example:

Program Success

Capture Acquisition Program

For standardization and governance we want to move away from the local forms and move to a global form to use on our landing pages/programs. This would enable us

to make updates to our forms from one place.

My question is how can we move to a global form but meet the capture acquisition program and program success requirements?

One idea we have is to approach it this way. Where form = global form and web page = landing page url.

My concern is that this may not be the "cleanest" way to do this.

What's the best way to tackle this?
