I’ve been “messing around” with Google Adsense for a few months now. I’ve also been on the other end – running Adwords campaigns that included the “Content Network” or, in other words, Adsense ads.

I’m sure there are people getting more clicks and making more money from the program than I am. Somebody blogging on electronics, cell phones or other consumer products are obviously more likely to get those high ticket clicks. Probably the most successful at raking in the Adsense cash are those who’s sole purpose is to capture the searches and direct the visitors to the ads.

The most obvious way to increase clicks is to increase the number of visitors to the page. Another way is to embed the ad in the content, so that the user may accidentally click on it, thinking it is part of the article. Yet another way is to optimize the page for the long tail keywords, and provide no useful content, so that the visitor’s best bet to get at the information they seek is to click on the ads. I would consider this last technique spam, and would never use it. I would also see it as having the best chance at high click-through.

From the Adwords advertiser’s perspective, would you want a lot of clicks coming from spam? Do you want to pay for visitor’s who have accidentally clicked on your ad because it has been embedded in the content? I think there are two sets of answers to those questions, depending who you are:

1. If you are a small business with a limited budget, the first thing I would do would be to unclick the “Content Network” box in you ad campaign. Stop advertising through Adsense for a period, and see if your conversion doesn’t increase. In addition, I’ve found that not only the clicks per page view increase when excluding the Adsense network, but when you do get a click it is more likely to convert to a sale.

2. If you are a larger company with a diverse marketing strategy, internet marketing is probably giving you your highest ROI of all channels, so you probably don’t mind the lower conversion per dollar, if it means higher overall volume.

So, to answer my own question: does Google Adsense make sense? – I’d say, if you are internet marketer who’s raison d’etre is to get those clicks, then yes, or course. For a site like mine, however, that has the ads up incidentally, “because I can,” then no, it doesn’t really make sense. It’s a waste of effort. But it’s still kind of fun.
