This might be a stupid question, but that thing where the page jumps as you&#x27;re about to touch it to tap or scroll, and instead unwittingly hit an ad -<p>Is that sometimes done on purpose? To increase clicks on ads?<p>Or is it just a matter of the dom redrawing in unpredictable ways as ad comment comes in?<p>I also often see the practice where a page completely loads, and then the page seems to entirely reload.  And it makes me wonder if that&#x27;s also an attempt to juice stats.
