I started 5 ads on a new bing ads account 2 days ago. After 5 hours was searching for them on bing and yahoo, i found 2 on yahoo and 1 on bing. 1 day later found all of them on yahoo and 2 on bing. After 2 days none on bing and finded all on yahoo. Account is few weeks old. I only had 1 ad wich is still live and getting impressions from bing and yahoo and now i made these 5 more ads. What do you think?
