Getting targeted Ads for "negative review" posts

Reading a recent post got me thinking about how you can ensure that you get the right Ads served to you if you are writing posts which are negatively reviewing a product or service.

The Negative post Problem
Now articles which negatively review a product may be of great interest to your readers. It may serve to warn them about the pitfalls of a product or service or tell them that its a scam or advise them of things that can go wrong and that they should be careful about. The problem is that the Adsense bot will look for keywords and won't understand the negative context of the post/article.

The result is that you will end up seeing Ads that are triggered by the keywords relating to the product and so your page will be filled with Ads for the very products that you are negatively reviewing. The problem of course is that this may reduce your potential income from Adsense.

The Negative Post solution
The solution is to use a combination of techniques.
First - make sure that within your post you include a section where you make some positive comments or discussion about some alternative products or services.
Second - use section targeting to highlight those sections so that Adsense targeting gives more weight to those parts of your post. (remember that section targeting needs a reasonable amount of content to work so your positive section needs to be of reasonable length.
Third - if section targeting alone doesn't work then you can use the competitive filter to weed out those ads that persist.
Fourth - don't sweat it too much. Some visitors will click the negatively reviewed products anyway just to see what the fuss is about!
