I am using #1 Amazon PPC Software - Adspert and #1 Google PPC Ads Software - Adspert as a landing page for Google Advertising. I tested on google page speed and got no result. I don’t think that my landing pages are so slow but they need to be checked by pro guys like you
And also I am curious that what you see on the landing page, is there any broken image, false layout, wrong dimensions? I would be appreciated if you can share your UI/UX feedback!
