My website has been navigating HORRIFICALLY slow according to Google Analytics large in part due to the ads on my site. I was recommended to use an ad as an iframe which supposedly loads the page faster with my banners, so I have implemented the iframe tags for my zones, but they also recommended doing Asynchronous for speed purposes. I am not seeing the ability to generate Asynchronous when getting my invocation code for the site. Please help. Also any additional advice on setting my site up so that the ads do not hold back any of the loading of my site would be very much appreciated.
