e-commerce starter needs help!

After reading lovethecoasts great post (http://forums.seochat.com/t42314/s.html), I just wondered what other ecommerce tips you guys could impart on an newbie like me! I fully understand seo, but this "e" stuff is a little new!

I understand the importance of:

Content/SEO
Security - of site/transactions
Promotion - on and off page
Affinity Marketing
Conversion of visitors to shoppers

I just wondered what else I was missing to add to my strategic plan! Any help would be appreciated.

I can't really expand much on lovethecoasts excellent post. When I teach this stuff to MBAs I have them focus on three key numbers - traffic, conversions, average profit per order. Obviously if you can increase any or all of those three items you will improve your financial performance. You already know how to increase traffic (SEO, marketing, etc.) and lovethecoast's post has great advice about conversions (especially shopping carts, which traditionally have a high abadonment rate). Profit per order is a bit more difficult and will depend on what you are selling. Try different product mixes. You can also try free shipping over a certain dollar amount per order. You might also try bundling - combining a number of products you sell. For example, I sell iPod accessories on one of my sites, so I would bundle up a number of accessories (case, FM transmitter, headphones) and call it the ultimate iPod kit.

Good luck.
