Typically not. They don't initialize the scripts that are required to track and log the impression.

It's pretty well known that techies don't click on ads, but they're only a smaller segment of the internet population.

..until your site has them as your core audience..

I was implying that ads isn't a good way to monetize that audience. Sponsored content or affiliate networks is better.

I was under the impression that most modern blockers (uBlock etc) simply block that request from the site to the adserver, so no they wouldn't count as an impression.
