Some days ago, we started getting attacked by malicious bots, who click all of our banners, producing CTR% to be way higher than normal. Google Analytics registers visits with just 1 second duration and highest bounce rate.
Our banners are invoked via Javascript.
We tested removing the <noscript> part of the code, but nothing happened.
Is there anything else we can do to prevent bots from clicking the served banners?
Thank you!
