Page Speed: render-blocking JS from Hubspot CDN, can I use async attribute?SOLVE
May 1, 2017 2:29 PM
To increase speed of rendering, is it advisable to asynchronously load this list of resources?
Also, we are seeing a number of redirects to display ad exchanges like Doubleclick, OpenX, adnxs.com, and Rubicon Project. Is anyone aware of why these un-related domains are being called in our pageloads and, if so, if they are necessary? We would like to eliminate them if possible.
Thanks in advance!
