Email marketing is critically important to many ecommerce merchants. But what happens if a merchant’s email is blocked by an Internet service provider? Or, worse yet, what happens if the merchant’s name or IP address lands on a blacklist? Email deliverability is our topic today, and to help us understand blacklists and ISP email blocking, we are joined by Laura Atkins. She’s co-founder of WordToTheWise, an anti-spam consulting and software firm.

The range of possible domain names is about to greatly increase. That’s because ICANN, the authoritative body over Internet domain names, is about to add new top-level domains — the portion to the right of the period — to include brand names and other customized names. To explain these new top level domains to us, we are joined by Gretchen Olive. She’s director of policy and industry affairs for Corporation Service Company, which consults with companies on domain name and trademark matters. She speaks with Practical Ecommerce’s Kerry Murdock.

Ecommerce merchants strive to increase the number of visitors to their sites that actually purchase products. Increasing those conversions frequently requires experimenting with new approaches. Merchants can test which of these experiments increase sales, and which do not. The testing can be automated, sophisticated — and it produces results. To explain multi-variable ecommerce testing to us, we are joined by Mark Simpson, the founder and president of Maxymiser, a testing, personalization and conversion-optimization firm. He speaks with Practical Ecommerce’s Kerry Murdock.

She speaks with Practical Ecommerce’s Kerry Murdock.

Yahoo! Small Business remains a leading, hosted platform for ecommerce businesses. But the company itself has experienced turmoil — the CEO was recently fired — and critics of the shopping cart platform say it’s dated. The man in charge of that platform is Tom Byun. He is vice president and general manager of Yahoo! Small Business, and he speaks with Practical Ecommerce’s Kerry Murdock on the state of Yahoo! and its hosted shopping cart.

The rush to sell products across multiple ecommerce channels is fine until a merchant starts to manage the back office complexities of updating inventory, prices, product descriptions, and then sales and shipments.

He is Fred Lizza, CEO of Dydacomp, makers of Multichannel Order Manager. He speaks with Practical Ecommerce’s Kerry Murdock on how merchants should best utilize third-party selling channels.

Sophisticated site search helps consumers find products on an ecommerce site, and therefore increases sales. But site search can also work with faceted category navigation to help consumers. The blending of site search with faceted category navigation is our topic, and to explain it we are joined by Scott Zielinski, co-founder of SearchSpring, a leading search solution provider. He speaks with Kerry Murdock of Practical Ecommerce.

The notion of combining an online marketplace with a payment platform, a shopping cart and a robust backend is not new. But when the marketplace is eBay, the payment platform is PayPal, the cart is Magento and the backend is GSI Commerce, that is news. eBay calls this new collaboration x.commerce. Its general manager is Matthew Mengerink. He speaks here with Practical Ecommerce’s Kerry Murdock.

Networking and exchanging ideas can help many online retailers. One organization that promotes this type of activity is Shop.org, the trade association for online merchants.

And he’s here to discuss Shop.org and its role in helping ecommerce merchants. He speaks with Practical Ecommerce’s Kerry Murdock.
