Choose the wrong keywords: Keyword selection is crucial to the success of your AdWords campaign. If you choose keywords that are too broad, you'll end up paying for clicks that aren't relevant to your business. On the other hand, if you choose keywords that are too specific, you'll miss out on potential customers who are searching for terms related to your business.
Set your bids too low: In order to get your ads seen by potential customers, you'll need to set your bids high enough to compete with other advertisers. However, if you set your bids too low, you'll end up wasting money on clicks that don't convert.
Target the wrong location: If you're targeting potential customers in a location that's not relevant to your business, you'll end up wasting money on clicks that will never lead to a sale. Make sure you target your ads to locations where your potential customers are actually located.
