I have been experimenting with FB's campaigns for a month or so now and for a while everything was fine, but I was limited to £35 per day spend. My CPC was set to .40 which was half the initial 'recommended' bid.
Everyday I hit my spend limit of £35 (exactly) but I wanted to increase traffic and therefore requested my daily limit was raised (straight to £250 though I only requested £100).
For the last few days I have barely spent anything on the campaign and I am being told that I need to be bidding £2 per click.
Has anyone else seen this or have any idea as to why this might be?
