establishing budget

prior to campaign launch

[fashezee]

Is there a way of establising an adequate budget that would provide substantial visibility for a site without having to open an adwords account a testing it for week or so. Lets say I would like a site to remain visible in adwords for 3 months; how can I determine the budget required if I have 30 keywords or so.

You can limit visibility to the available budget. If you get a lot of clicks then you may go off line for part of the day.

With experience of your sector and keywords you can arrive a a ball park figure but if people come into the market part way through your campaign with significantly higher bids then all bets are off.
