Nope. Never experienced it but I guess Facebook does a good job promoting ads. I’ve got an old Facebook page for a blog and it gained 1500 likes in a span of one month without me purchasing an ad package or what. So what more if you use paid advertising.
I actually did, and it worked out quite cheap. I think it was something like $5 for a whole month. In that month, I gained fresh new views, likes and enquiries about stuff I sell. So for me, it was well worth it 🙂
