Ecommerce Marketing strategies that are not focused most likely won't work. How could it work when people have more than three or four priorities to deal with? It is hard enough to do one thing, how much harder would it be to think of doing five or more priorities? Objectives like that almost always get lost. When you have 20 strategic objectives in a plan, you won't accomplish any.
Focus on your strength or your company's strengths. Play toward what you do best and take advantage of the opportunities that is before you.
Focus on selected target markets and selected target market needs and selected product or service offerings.
Establish milestone you can celebrate after completion. Milestones like, "register domain today", or "finalize website design by end of month", and so on! Another good milestone is "publish one relevant content a day for 100 days". Or "get listed on the first page of Google for a particular keyword in 3 months".
I know you want to get sales and make money, but to reach that level, you have to build your business first. Trying to do everything at once is a recipe for failure, in my opinion!
