Read on “Cruelty’s Blog” (German) which I found via Yigg.de:
“Layer-Ads is […] just a simple layer that moves into view with a little animation.
Thus, the user is not irritated and quickly finds the Close button, if he doesn’t wish the ad.”
(Emphasis and translation mine. And dear Cruelty, I don’t want to attack you personally, I just want to tell my opinion on such ads.)
Hmm… does anyone know anyone who doesn’t mind an ad thingy of about 750×500 pixels covering the page content? (Except those making money from it, of course…) Even if it disappears after viewing and closing once for all future (what I doubt; at least, it seems to work that way temporarily), that could alienate one visitor or another – and if even the Yigg screenshot consists almost completely of an 1&1 ad, one could think: ‘Oh, that blog with that ads, no, don’t need to go there.’
By the way, Layer-Ads.de says (my translation):
“Even visitors with pop-up blockers will see a layer.
The webmaster won’t lose a single compensated visitor.”
My Firefox–Proxomitron combination worked anyway, I had to dig up the unfiltered IE to get an impression of these ads.
