Review campaign doesn't count as advertisement, if you want to advertise your business here and you launch a review campaign to get honest feedback, take note that if you pull the plug there, it won't be long before people forget about your company and what you offer; the review campaign is to get feeback in order to provide the best service to your customers.

Signature campaign is were the advertisement begins, members will advertise your company with posts they make and with every single post they have made in the forum, until they take the signatures off. If your company's name is everywhere in the signature and avatar of a lot of member's, week in and week out, people will use your services if what you offer is great and if you had made adjustments to your product after the review campaign, that is if you organized one.
