Newspapers rely on advertising as their main source of incoming. The few dollars you pay for a copy are for distribution costs. That being said, there has been a massive struggle to move that business model as-is onto the internet, for various reasons, including people running adblockers and a general lack of understanding of this new medium. As webmasters become more desperate for advertising sales, they come up with new (annoying) ideas to ensure visibility - popups, popunders, popins, and forced ads before videos. All of these just cause frustration on both sides and users use ad blockers, or just learn to ignore them.
There's been a big topic of relevance. Users respond better to adverts that are more relevant to them. I call shenanigans on this. This is only partially true. If I am browsing a site related to financial markets, I am not interesting in Hobby King targeting an advert of a part that I looked at on their site a few days prior. My mindset while viewing this site is that of business, not play. In the same vein, Destructoid has the following adverts on their home page (probably targeted to me): Social Media Marketing from Vertical Response, Start your own gaming business from Game Wars, The frequent Download/Play belonging to some cellphone subscription service, Linode (even though I am a linode customer), Google Apps for Business, A conference for Data Center World. Maybe some of these are targeted to me, but while I am browsing a gaming site, I don't care about anything else that is not related to gaming. My point here is, relevance is true, but target something at me that is relevant to me AND relevant to what I am currently doing. I don't want to have to think about or reminded about work while I am on Destructoid.
Back in the day before the rise of these ad delivery networks, people used to put adverts up on their site manually. And only adverts that were relevant to them and their audience. Nowadays, these ad networks do allow you to customize the type of adverts that appear on your site. It seems that this is not being done, and webmasters are using the shotgun approach, allowing any type of advert to be targeted to their users. This is just plain laziness.
Also, where is the sponsorship that we see everywhere else? Companies pay a premium to sponsor a TV show (blah blah brought to you buy blah blah). This helps both the advertiser target a specific audience and the content provider pay for the content.
If Destructoid want to continue to rely on advertising for their income (and please do), they need to do some serious work on making sure that the advertisers on their site are relevant to themselves and their users. Content producers off-line have very close relationships with their advertisers. Strike up a deal with Razer or EA to do some skinning just before a product launch. I'm not suggesting "selling out", but rather realize that you are running a business selling content to us. We buy it by looking at your adverts. If we don't like your adverts, we will block them. If we don't like your content, we won't visit your site. It is up to you to connect us with your advertisers via your content.
