I'm running ads about services for widgets. My ads are often get commented on, both in positive and negative light, about the widgets themselves. In other words, people are praising or complaining about widgets, not my services for those widgets.
How do you view those comments? Are they useful for the ads in any way (like it looks more like a live post when there are lots of comments) or are they detrimental (since they may take attention away from the actual service I'm trying to sell).
I can't claim that I know exactly how FB click bidding system works but it looks like my CPC is slightly lower on ads that receive more Likes, and the way to receive likes seems to be to encourage commenting. But it can also backfire if people start to criticize widgets.
