What should I never do with a rotator?
You should never spawn multiple windows, tabs or iframes that point to ClickMagick rotators at the same time.
If you do, your URLs are NOT guaranteed to rotate properly because when a browser client (your user’s browser) sends multiple requests to a web server (ClickMagick), the requests are not necessarily processed in any particular order.
This rarely works as intended on most mobile devices, and many users have browser plug-ins or security software that also prevent multiple windows from spawning at the same time, so the number of actual “clicks” you get to your rotators is going to be completely random as well.
99.9% of the time we see this it’s done via hidden iframes to generate additional (worthless) clicks to “solo ad” customers, and since there’s no legitimate reason for this it’s not something ClickMagick can support.
