Freee version is ok, if you are looking for random traffic, at the end of the day if you want social and google ranking attention you have to pay, if you are a campny / service 36 GBP a month is nothing compared to possible customers, even if you pay 36 GBP and you get 5 customers for 1000+ impressions / " hits ", each customer pays 90+ GBP well, you have it right there MONEY. Money is not free, to get it money you have to spend money, and with this service you simply have to do that. I would not reccomend the free service as you cant pick traffic location.
Pro (paid)
Traffic location
Enabled bounce rate reduction
Social traffic
Key word associated traffic ( google, etc)
Referrals
Direct Links
Cons
Its not perfect, I would never recommend on a long term as you cannot fully control the bounce rate and regardless its limited to 60 seconds which can screw up your analytic results.
Its good for a starting buisness who
