In Page Push vs Classic Push

[dogmatik]

So I recently ran a campaign (well two) both to the same landing page offer with the only difference being one as in-page push and the other classic push.

For the in-page push I had the following:

Impressions	Ad Clicks	Offer Clicks
140,386	1,998	15

And for the classic push:

Impressions	Ad Clicks	Offer Clicks
2,714,904	420	109

Those are impressions and clicks to my lander and then offer.

Is it normal to see such a difference in the CTR rate for in-page?
This was my first in-page push campaign. Are people just miss clicking?
Both campaigns were targeting mobile phones only.

Thanks in advance for any
