At MT, you get a choice of pop-up, either a landing page, which is a browser page at 750x500, or a "creative" which pops-up without the browser address bar and toolbar in w window you can set the height and width for (less than 750x550). I started using Landing pages, but recently thought maybe creatives is a better way to go, since I can create a "page" at a specific size and have it pop without browser address bar and toolbar. Here's an example of a "creative" page:
**** Berry
This should pop at the exact size of the image. What do you guys think? Is this a bad strategy? None of my landing pages are converting, so I'm trying different tactics.
