Adwords + CB landing page

Hi,

I'm trying Adwords PPC --> Instapage landing page with a custom domain --> CB affiliate product.

I picked a decent keyword in a product niche that's not about making money or IM. The product has some good gravity and has been around for a few years.

My issue is that I have different analytics from Adwords, Instapage and Clickbank and nothing is making sense!

For example yesterday:
Adwords is showing 22 clicks
Instapage 7 clicks (4 A and 3 B variations)
Clickbank 10 hops (0 order form impression!)

I have two main questions:
1-How do I know which tracking is correct? Is there a lag/discrepancy in how Adwords/Instapage/Clickbank report clicks?
2-If I want to start optimizing, where do I start? The CB product, the landing page or the Adwords ADs?

Thanks everyone!

anybody?

You can see that stats from Clickbank are out of question, as the user who lands on the insta gram page, will not always click on the button which will proceed to the clickbank site, so not every user who lands on your site, actually clicks on that, i will consider Adword stats more reliable

I would say instapage is more accurate, Also try to put your own stat counter on your page to double check that one.

thanks guys, my email notifications are not working and did not see your responses in time.

I've paused the adwords campaign and decided to build my own landing page so that I can have total control on the user experience and analytics.

I've tried Thesis + Marketer's Delight but found that to be a nightmare and requested refunds.

Can you recommend any good WP landing page theme or template that I can use?
