Refuse to Pull Failing Campaigns: Some people get so stubborn and convince themselves that a campaign should be successful even when it proves not to be. Instead of shutting down campaigns that are not profitable, they forge ahead only to lose more money. Don't let this be you. If you have given a campaign ample time and it is not making you money, don't be afraid to pull it.

Don't Track Your Advertising Efforts: Not tracking your advertising efforts can really be a hindrance to your online success. If you fail to track where you are advertising or what pay-per-click words you are using, you won't know what is working and what is not. Therefore, it is very important that you don't get lazy on this step. Be sure to track all of your ads.

Don't Test Your Landing Pages: Not taking the time to test your landing pages can also be a big mistake. Periodically create a new landing page and see if it makes you more sales. Keep the former ones and if you find that your newest efforts are performing more poorly then the former ones, pull them and replace them with the ones that were doing well.
