Should you block ads online?

Over the weekend, technology news and analysis site Ars Technica posted an impassioned plea for its readers not to use ad blockers. Software tools that block advertisements on websites are common these days. You can download them as extensions for many web browsers, or as freeware. Using them stops your browser from displaying the advertising banners and other commercials, such as Google Ads, that you often find on websites. Advocates say that it makes the experience of reading a website more streamlined. Opponents, such as Ars Technica, say that it makes it harder to bring readers the content that they love.


"Did you know that blocking ads truly hurts the websites you visit?" said Ars Technica writer Ken Fisher. "Imagine running a restaurant where 40% of the people who came and ate didn't pay. In a way, that's what ad blocking is doing to us."


Whether or not you click on an ad is irrelevant, Fisher says. The simple fact that you see the advertisement when you look at the content on a site is enough to satisfy the advertiser in many cases. Known as cost-per-impression, this advertising model is common online. It differs from a cost-per-click model, where sites hosting online advertisements are only paid when you click on the advertising link.


Ars Technica tried an experiment last week, where it made its content disappear for visitors who were using a popular ad blocking tool. Technically, it turns out that it is possible to do this. However, socially, the website found that many of its visitors were not blocking online commercials out of malice.


Of course, there are more intrusive models than simply running an advertising banner across the top of the screen. Some websites make you look at an advertisement when you hit the site, forcing you to wait, or to click on a link manually to get past the ad. Others throw up animated advertisements while you are reading the text (which irritates me beyond belief, personally).


There is one other issue to consider when thinking about online advertisements. It is useful to think of the advertising banner that you see in many websites as a kind of window into advertising land, rather than a piece of content that the website is responsible for. Many websites grant advertising companies access to their websites through this window, meaning that the advertising syndicates can serve up whatever advertising content they want. 


Online criminals have devised ways to inject malicious content via these advertising services, that can infect users' computers without the hosting website being responsible for the advertising content at all. In some cases, this has resulted in visitors' computers being infected by the advertising content on a website. Recently, the New York Times was duped into running an advertisement that used malicious code to throw up a browser window selling fake antivirus software.


As someone that makes his living writing for websites, I want them to be commercially viable. I don't write for free. Geektown and the other websites that I write for how to make their money from somewhere. Making people pay for content via subscription would drastically reduce the reader base, and I like the idea of being able to get content online for free, in exchange for looking at an advertisement.


As readers, how do you want to keep sites viable? Are you willing to look at advertisements? Would you rather pay for content, and how much would this restrict what you see online?
