I'm using global target for PPC ads for a campaign at the moment as the product is available worldwide through me and is geared to a worldwide audience.

I have a low budget and have ads running below 35p a click (many much lower) using just five keywords (phrases but loose set) that cover everything I want to say. A single consise advert is displayed with no alteration but in all languages.

Advertising CTR is 4.8% approx and sign up to the product is running at just over 6% on click throughs. Problem is that the daily budget is exhausted after under 4 hours at that price. Reducing is an option as I have at least a 30% margin at present to reduce and prominence is only a 4.6 on average. A 10% reduction can be achieved for all but one word or phrase without affecting position. Minimum accepted bid is 2p but the position is naturally lousy. The campaign runs from 02.00-08.00 but is exhausted no later than 06.00 every day.

The product is residual and the website offers a free software download as part of the product. Not surprisingly the take up rate is good in areas reported to have official sanction by national Governments and the Far East is the most popular area for customers, despite the product being EU based as customers have a lower income.

My question is simple...shall I risk a modest reduction in price which affects my position in order to increase availability of advertising or raid the piggy bank to make the daily allowance higher? Or shall I just leave it as it is?

My question about maintaining the status quo is that the Far East is the best area for the product as there is weak competition from local suppliers and customers are now shopping around for alternatives. At the rate I am operating I can sustain this without overextending and the progress with customer take up is sustained. It means that although it is galling not to run a 24/7 campaign at current rates as I can't afford that at present for the product, the take up is good and this can only benefit me in the long term.

What should I do in your opinion?
