Everything was OK, visitors came to my site from Google Adwords, all my limit was spent every day. Until today. I look at my logs and see that from Google + Search Network noone comes. All what is left is Content network. And I didn't change the ads, I didn't change anything. Why could it be so?
Has your average position dropped? Possibly a new competitior outbidding you for your keyterms, or possibly a drop in quality score for your adverts that have dropped your advert down/off the front page. Have your impressions dropped? Or your CTR?
I am just not receiving anything from Google + Search network. Avg.Pos is still OK, but it is calculated for the numbers I had when I was receiving clicks from Google CPC. My impressions have dropped to zero, so CTR is zero. But content network is working the same. So, if I have been dropped off the front page, then I would still receive visitors from the second page? Bu I have nothing!
