Above link is a Marketing Blog ran by Seth Godin and the paragraph below is what he wrote on his blog.
Digital media expands. It’s not like paper, it can get bigger. As digital marketers seek to increase profits, they almost always make the same mistake. They continue to add more clutter, messaging and offers, because, hey, it’s free. One more link, one more banner, one more side deal on the Groupon page. Economics tells us that the right thing to do is run the factory until the last item produced is being sold at marginal cost. In other words, keep adding until it doesn’t work any more. In fact, human behavior tells us that this is a more permanent effect than we realize. Once you overload the user, you train them not to pay attention. More clutter isn’t free. In fact, more clutter is a permanent shift, a desensitization to all the information, not just the last bit. And it’s hard to go backward. More is not always better. In fact, more is almost never better.
I can’t agree more on how more clutter declines the profit of one’s company. I have seen many cases where they have many ads on their website and they make profit out of it. From what people understand, having more ads on their website would earn them more profit. However, the truth is different. Having more ads would make each one of the ads smaller than it would if there are less ads. Since the website has a limited space that only so many ads can fit in. However, people tend to pay less attention when there are lots of stuff on the website which means that the marketing effect decreases. There is no point of ads if they do not catches viewers’ attention. No more company would want to put an ad on this website and this would decline the profit of one’s company.
