I don't like advertising but I understand that businesses need to be able to promote their products and services, that running websites does cost money and website owners are entitled to some renumeration for their costs and efforts.
Its the advertising industry itself, with it's philosophy of "how do we get inside people's heads and make them want to buy the product" that I find unacceptable, not the web site owners trying to scratch a living with a few ads on their site. So my criteria for acceptable ads are:
1. No tracking or profiling of my online activity. This is non-negotiable. If you want to serve "relevant" advertising, base it on the page content, not what you've gathered about the person viewing it. So if a page is about cars, have adverts for cars or car parts. If the page is about home improvement, have ads for hardware stores and such. If I'm on such a page long enough to read it all, I'm more likely to be interested in an ad that relates to that page, and there's no tracking or profiling or "personalisation" necessary.
2. No obscuring or blocking page content. That not only includes scroll-overs and popup divs obscuring the page, it also includes "click-through" pages requiring me to click off a dozen or more "offers" before getting to the content. Have the ads in a sidebar or split in the article or similar, not as an obscuring invasive block getting in my face.
3. No animation or sound. If your ad is a constant distraction from my ability to focus on the article I will block it so I can concentrate. So bouncing monkeys, jiggling credit cards, cycling colours and waving girls are not acceptable. Neither are sudden voices or music interrupting the music I'm currently listening to while browsing the site. It's not going to make me buy your product, it's going to make me hate you.
4. Preferably text-only, no imagery. Advertisers tend to use distracting, vivid images to try to pull your attention off the page to the ad. In some cases that can be as bad as animation for distraction, so a Google-style text-only ad is a better way to go. (An example of this is Jim Wales' "puppy-dog eyes" guilt-trip banners on Wikipedia during their funding drives. Those get blocked the moment they come up.)
5. Adverts must be clearly marked as such. This means that it's not sneakily made to look like part of the article, it has to be clearly captioned as being sponsored or an advert. It also includes deceptive ads made to look like Windows error dialogs and similar things to try and fool people into clicking on them, which is something I think should be charged as fraud or misrepresentation.
I think a majority of ad-blocker users would agree with me that if the advertising industry conformed to these five criteria, most of us would be willing to unblock ads. All the advertising industry has to do is take some social responsibility and understand that people are not robots to be programmed. But sadly I feel it'll be a cold day in hell before anything like that happens.
Wherefore I will continue using an adblocker.
