I am looking for resources that compare the different Landing Page Optimization companies that are available. I want to generate some compare/contrast criteria for my company about the different Landing Page Testing Companies, but I am having a hard time finding resources. Any suggestions? Thank you.

Are you talking about AdWords / PPC landing page optimization or search engine optimization?

I work for an SEM/PPC Optimization company, but we are looking to outsource our Landing Page Optimization services. For example, if one of our clients would like to improve their conversions we might recommend taking a closer look at their landing pages and making some changes to the pages themselves. I would like set up some criteria for finding the best landing page testing and optimization company out there (i.e. Offermatica, Optimost, Widemile, etc.) in order to partner with them to meet my companies needs.

If you are outsourcing and you currently know what you're doing, it sounds to me that what you should be looking for is a company that will do your bidding.

Service sounds like the name of the game. If you are giving THEM business, they should be at your disposable, provide updates, etc.

But, I suppose with Service, everyone has their opinions as to which one of those provides better service.

Hi there, I work in analytics at a premier financial services company and we use www.memetrics.com to help us optimize our landing pages and direct mail. If you want to outsource your LPO activites, you may want to consider RedbricksMedia or Zaaz.
I hope this helps.
