Well it depends on your niche and traffic if you can keep the same amount of traffic and if you have a good niche most of the time your cpc will be the same.
Yeah depends on your niche, but also the season, e.g christmas used to be bad for me, because everyone is around the fire instead of the computer! Also if you had a site on say valentines then it would be really popular on valentines day in feb and thats it.

Well, the site looks solid. From what I saw, the ads were more or less well blended. I believe it basically relates back to it being March, and not a hot month. Also, hosting is a niche that's kind of overused as it is, which could contribute to the problem.
