4. Measure what matters, when it matters; the holidays aren't for everyone
Think about whether now is the right time for you to try to compete with big-box retailers, especially in the area of price. If your holiday marketing campaign is costing your business too much and doesn't look like it will be successful or even sustainable throughout the season, abandon course. Holiday campaigns that miss the mark can be especially costly for your business. Sometimes it's better to focus on the time of year you can be most competitive.
Before abandoning efforts, however, make sure you're measuring against the marketing goals you set for the holidays. For example, if your goal is to increase brand awareness by generating traffic to your website, track your email click-through rates. And don't focus too much on metrics that are not related to your goals. If you want to increase revenue, for example, and you're performing well in that area, don't sweat lower email open rates.
