Online and Internet marketers have fierce global competition. The marketplace is open to all. There are very few obstacles hindering email marketers today when wanting to reach millions. In a bad economy, marketers are hurting. But, at the same time, we cannot afford to make too many mistakes. Mistakes and miscalculations are very costly. Unfortunately, there is no guarantee or marketing guide created, that can promise instant success. If it does, it is dishonest. Don't change your ads too often. All the studies show that customers and prospects need to see your ad at least seven times before it makes an impression, before a purchase is conceived. Give them time to get a general sense of your brand and what you are offering. Be consistent.
