Budget Crossed

[Susmita]

Hi

Since last few days for one of my ad campaign budget is crossing by high amount.

Is it good or bad?

I guess bad if your not making money on the traffic :(

One day when the budget crossed conversion was much higher than the other days, where as in another day when the budget crossed by same amount conversion was not that good.

Why things vary in google without giving a logical clue.
