How much does it cost to advertise a website on google and yahoo?

In drawing up a budget for a Pay Per Click campaign, it’s crucial to focus both on your ROI (return on investment) percentage and on your net profit. A small scale campaign can bring home a tremendous ROI percentage but relatively minor net profits. Conversely, a relatively moderately profitable ROI can generate huge influxes of cash to your advertising budget if you do large volume business. In other words, it’s difficult to measure your Pay Per Click costs and benefits in the abstract. Perhaps more important is figuring out how to optimize the return you get on every dollar of advertising spent. If you outlay just $4,000 to get your campaign started, you may not see a huge return, even if you create a profitable campaign. That said, while it may be tempting to outlay tens of thousand of dollars to reach consumers via both broad keywords and niche categories, you don’t want to blow your Pay Per Click ad budget during the first week, unless it brings a good ROI, and then you need to up your budget.
