The problem with site targeted CPC campaigns and ingreasing bids is that somehow it takes Adwords about two or three days before it will start to use the new bids. This doesn't make any sense...
I used to target two websites and my bid was 0,04. "Website 1" to promote "website A". And "Website 2" to promote "website B". This was giving me daily about 900 clicks and 125.000 views for the first targeted website and about 1.200 clicks and 125.000 views for the second targeted website. Each day, day in day out. For over two months.
And then (as mentioned in my last post) it suddenly stopped. I raised my bid since then each day. At one moment I was bidding 8 dollars per click. Result: zero views.
Looks like Google does not like my money anymore. Or those two websites (not related to each other) both blocked the two websites (also not related to each other) I was promoting on the exact same day. But that is very unlikely.
