I read in one of the posts to separate the Tracking and LP on different servers. I don't understand the benefits, as I would imagine after the tracking it only needs to bounce to the same IP address for the LP.
Can someone please explain further.
Thanks!
It depends on the use case. Sometimes the trackers are so heavy that serving the tracking, landing page, and all landing page assets (images, javascript, css, etc) from one server is just too much and will slow each other down. Sometimes you want to keep your tracking isolated from your landing pages for privacy reasons... so a competitor can't do a reverse IP lookup on your tracking domain and find all your landing pages.
In terms of performance, you're actually best off serving the tracking and landing page from not only the same server/ip, but same domain as well. Otherwise, upon the redirect, the client has to do a new DNS lookup, and establish a new TCP connection to the 2nd domain... which costs you at least hundreds of milliseconds in page load time... and even more on mobile.
Yep, I have tested it and serving from the same domain & server can make a change in mobile camps.
