Ad Blocking

Yahoo ignoring Ad Blocking

I've noticed that Yahoo's ad blocking works very poorly, if at all...

I find it hard to believe that this is a bug that they can't fix.

I'm starting to think that they are ignoring the ad blocking in order to satisfy their advertisers. Even if the publisher wishes to not displays an advertiser's ads, I think Yahoo may be showing them anyway just to get their advertisers' ads displayed on good sites...

any opinions?

It has worked perfectly thus far for me.

intersting that it has worked well for you...

may i ask what category of ads your site displays?

my thinking is that ive blocked quite a few ads from showing and i may have blocked either too many or ive blocked some advertisers that they want to keep happy so they are overriding my blocking requests

i had sent an email to support and got an ambiguos reply about keeping both advertisers and publishers happy...

im not too concerned since the ads im trying to block actually bring in more revenue (at least i would think so) but some of my site visitors are going to be unhappy seeing the ads...

I haven't blocked any within the categories I am choosing. The ones I have blocked are the RON ads everyone sees. The Vonage, etc.

I've noticed that the domain prefix is needed to block the ad effectively...

like if i block:


that doesn't/didn't necessarily block

that makes sense...

i always add domains to my blocking list w.out the 'www'... for example:


usually this would block any combination of the domain name being used: listing cnn.com would be expected to block 'www.cnn.com', 'video.cnn.com', or any other subdomain used...

this may not be the case for Yahoo

I've updated my blocking list to look like this:


seems to be working...

thanks for the idea!
