I'm sure I'm going to ruffle more than a few feathers with this article, but in my opinion, any business that sells a product or a service shouldn't have Adsense on their website. Why? Because with Adsense, you're promoting your competition, that's why. If you had a brick and mortar business, would you put your competitor's ads in your store window? Of course you wouldn't. That wouldn't make any sense, now would it?
Well, by having Adsense on your website, you're essentially doing the same thing. That doesn't make any sense either. Not to mention the fact that there are some people who won't even patronize your website, if you have Adsense on it. Here's something else to consider: First impressions. I've had people tell me that when they see a website with Adsense on it, they automatically assume that website isn't doing too well and that the site is using Adsense to stay afloat financially.
Whether that's the case or not, that's definitely not an impression you want to make.
Besides, it's tough enough to convert visitors to your website into paying customers, without adding your competitor's ads to the equation. Granted, many buyers are going to check out your competition anyway, before they make their decision to purchase. But heck, don't make it easy for them by having your competitor's ads in plain sight right on your own website. And even if you enable the Adsense filter to block out competitive ads, the ads themselves are still a distraction.
In fact, I've actually had people tell me that they've clicked on the ads accidentally, because they thought the ads were part of the content they were reading, and they ended up buying from a competing website.
Why sabotage your own efforts by throwing distracting ads into the mix? See my point?
If you want to monetize your site, affiliate programs are a much better option, when you take into consideration the measly few cents per click that Google is going to pay you. C'mon, be honest. How much was your last Adsense check? $150.00 $100.00 When you stop to think about it, Adsense is hardly worth the effort is it?
The fact of the matter is, with very few exceptions, unless your website has mega-traffic, those huge Adsense checks are simply not attainable. And even if you have mega-traffic, there are no guarantees.
