Now, there is nothing wrong with a product review, or even a "full page" advertisement. In fact these things can be very helpful if I want to learn about a specific product. Product review articles and comparisons can be very interesting - if I want a product. Often though, I'm looking for something that isn't product specific, like a recipe or information about how to better use social media. (I'm always learning.)
When I click on a link that turns out to be nothing more than a sales pitch it becomes frustrating. Not to mention I make a point to never, if possible, visit the site again. So not only did the company not solve my problem, they have permanently damaged any possible relationship we might have had.
If you are planning on creating one of these deceptive style articles then remember this. No one likes a bait and switch.
Do you know of a company that uses this type of tactic? List them in the comments - so we can all avoid them.
