Every day I check out the 100s of subscriptions in my RSS feed about marketing, PR, advertising, branding, social media, and a host of other topics of interest to small businesses that sell online. Most of what gets posted isn’t earth shattering but I reserve Fridays for the best reads of the week. So here you have it, the most valuable things I read in the business blogosphere this week:

• 5 Ways to Build Your Email Marketing List
• Stopping Shopping Cart Abandonment
• Tips on Getting Into Magazines
• SEO: The Myth of Duplicate Content
• Three things you can do tomorrow to create sales – Be forewarned that the title of this post is a teeny bit misleading because it’s more about learning how to ask the right questions to increase sales. I really loved this post because it did a great job of saying what I was trying to say earlier this week.
• E-commerce strategy: that’s not your business! – This is a great post about understanding what you actually sell (hint: it’s not products and services).
• 6 Things to Consider When Creating a Promotion for Your Store
• “What I’ve Learned from Taking Thousands for Product Shots”
• Calculating the Lifetime Value of a Customer – This is a bit of a marketing nerd’s read but I still think it’s a good one to try to follow because it makes an important point about the value of long term customers
