Hello everyone, I'm new to this forum but I thinks this could be an interesting topic. Right now I'm doing media buying in a few verticals. For my Landingpages I use an VPS with cloudflare CDN to speed up everything. I read an articel about Rackspace cloud files an thought I can host my files there, because I don't have to manage the Server and only pay for what I need. So I switched everything to Rackspace and then my conversion just dropped extremely for more then 24 hours, after this time I switched backed to my old envoirement. In the 24 hours I sent arround 5k clicks over the Landingpages so this should be statistical significant. What I want to do in this case study is analyzing the services and split test them against each other and then share the everything with you. Right now I set up the Landingpages and configurate a few campaigns to see what happens in comparison. The next thing to do is analyze both CDN with googles page speed Cheers, first update will come in a few days.
