I was thinking about all these new ad hiders, such as adblock for firefox and wondered how many users were blocking my ads.

I searched google for it and found a script (AdBlock Detection Script | AdBlock.org) that 'attempts' to stop the ad hiding but adblock has updated and got around this script.

I was wondering if anyone knew about a script that detects if an image isn't being shown through javascript. Searched google but it returns so many ad blocking software sites.

Thanks, Peter

Not found any

you cannot.

Adblock match objects via the dom tree, that means that even javascript, which modify the dom tree, will not be able to avoid it.

Now, as it use regular expressions to block ads, you may have success be renomming the part that display your ads.
But it won't work with external ads display (like adsense) as the adsense source domain can be blacklisted, and you have no way to change that.

In other words, I don't think you can really stops adblock users from blocking your ads.

I am myself a 3+ years adblock, and I have unblocked some sites that provide useful infos, because I find normal a reasonable amount of ads.
But when I see flashing/blinking ads all over the page, with 3 popunder and a mixure of 4 different ads provider, I simply won't let any ads appears.


Waddayaknow... I'm one of those old guys who knew netscape 2 and discovered the web at the same time it was done...
I'm attached to a certain philosophy for it, the first being that I want to choose what I want to see.

You can! It's just a matter of knowing how they work.

For example they may block an iframe, so don't put ads in an iframe. Many ads are put on a site via Javascript, advoid these ad peoples,
From my own know how, I've found having an on-site ad system (.jpg or .gif, not .swf adverts) tend to do better. Advoid using popular ad sites, it's likely adblocker will have blocked there server to stop the evil ads.
Try alternative ways to show ads, for example "Text link here, $5 a month" is a great way around the blockers.
I have heard of people making banners 469x81 to advoid some lame ad blockers, and it seems to work.

Though, it's really down to what a user see on a page, if there anything like me a nice banner may be clicked, though If i go to site i know will swamp me with ads, I may turn of images and javascript.

I would simply compare the requests for the page in my server log with the number of impressions reported by google adsense.
The difference is the number of people who did not see the ad.
