In recent weeks I have also given much thought to the rise of ad blockers, which I suspect have been eroding my ctr over the past three years or so.
Have you come across a way to quantify this? I wouldn't mind trying to identify the impact it may or may not be having on my site. I don't often run into friends, colleagues, etc. that use an ad blocker but that does not mean it is not an issue.
