Product review articles almost always give a link to where to buy the thing, and that link always points to #Amazon, which I find disturbing. Are they getting a kickback from Amazon, or are they just being lazy? I'm guessing the latter.
@resist1984 looking at the link, you can tell if it is Amazon associate link. If it is, then yes they get a percentage of sale. Bloggers got to eat to.
@resist1984 I'm not liking all the paid reviews in SERP either. They are a problem on Amazon itself, too. Forums seem to be the best way to find unbiased info on a product/service.
@DavidB Such a search engine would naturally root out the /professional/ reviewers, and let the more meaningful reviews (from consumers) rise to the top.
