Just as the title says: Have you ever clicked on an ad, knowing it was an ad, on purpose? What ad was it? Why did you click it?
Curious because I realized I have not once in my life clicked on an ad shown online on purpose. Accidentally, and being tricked into clicking the wrong thing sure; never with intent though.
to provide an answer from the advertiser’s perspective, they are very aware that the Click Through Rate (CTR) is incredibly low, as corroborated by the comments, actually measured at about 0.2%.
because it’s so small and potentially difficult to track, other metrics besides CTR are used alongside by marketers, including total impressions, conversion rates between other channels and, yes, tracing your browsing history by way of cookies and other invasive digital tools.
