Search engine advertising

Search engine advertising is the generic name for the sponsored links that appear alongside organic search engine results. All major search engines offer a self-serve advertising system where advertisers can place competing bids for the right to take the most prominent position within the paid listings. The advertiser can decide what amount they literally want to "pay-per-click" (abbreviated PPC).

Things you should know

• It isn't always necessary to gain the top position. In fact, even the top bid doesn't guarantee the very first spot since they are rotated among the top 3 spots. Furthermore, the top spots sometimes attract very soft interest clicks rather than serious buyers. Position 2-4 might be provide better value for the money; try it and see what works best for you.
• The advertising system recommends a certain minimum amount for a guaranteed position. The amount has a tendency to be slightly over-inflated, so don't be afraid to bid slightly under. Watch your position slowly, and make small incremental increases rather than big jumps in order to save mon
• A problem called "click fraud" has haunted PPC since its inception. Occasionally, unscrupulous competitors will click your ads in order to regain a better spot. But the larger problem lies in the fact that search engines run syndicated advertising networks on a very large number of 3rd party sites. Most website owners are honest, but a small minority of others are designed solely to defraud the advertiser. This shouldn't be a big concern, but if you are worried stick to advertising on search engine results only where the problem is contained.
