This reply was preceded by a full screen Java ad that is irrelevant to my usual searching. Anyway, in general yes, they are related to some degree of technical nature.

I do click on those related to help this forum and leave the ads on new tabs open for a while. Hope that time is enough for google to account as a legitimate click.

The usual ad is at athe bottom of the page with an arrow to push it back down.
