WooCommerce VS Shopify
Shopify is a great platform. It is SEO friendly, affordable, easy, quick to set up. But it is not as customizable as WordPress by a longshot. It is much harder to create a branded look that perfectly and uniquely works for your business. Many of my small businesses are concerned with looking local and personal, and Shopify themes do not really do that out of the box. Moreover, Shopify is limited by the platform. In the future, if they raise rates, or decide your content is no good, you do not own your site, you can be kicked off the platform. Lastly, though their SEO features are good for beginners, they are not anywhere near what can be accomplished by a good WordPress website, where plugins allow for tech to be updated much faster than on shopify, where modules need to be vetted 3 ways to sunday before they can roll out.
WooCommerce VS Volusion
Volusion & BigCommerce are solid platforms. Great customer support, fast websites, secure servers, easy to set up. So why would we possibly not recommend them? The real reason comes from a lack of ownership and extensibility. Changes to advertising policies can severely affect your business. When you are on someone else’s platform, you are subject to their rules, and dependent on their good service. If their company is sold or folds, you may not have as many options as you want. WordPress E-commerce is also awesome for the extensibility. We can add forums, blogs, custom post types and a ton of other SEO and display capabilities. We can create fine detail landing pages and split test minute changes, which those platforms are not optimized for, and by the time they are WordPress will be doing things which they are not.
WooCommerce VS Magento
Magento is really one of the few apples to apples comparisons. There are plenty of other smaller market share carts, from Cart66 to Jigoshop, but Magento is actually a robust self hosted E-commerce platform, with unlimited extensibility. That being said, unless you are running an inventory of 10,000’s of products selling in every country, then you should probably work with WooCommerce. We routinely run into clients who are trying to migrate off Magento, for the reason that it is overly complex, does not have the support community like WordPress, very few skilled developers who specialize in that platform, and while it is extensible, it is expensive to do, where WooCommerce & WordPress often have the module you need prepackaged for a low fee.
WooCommerce VS WP E-commerce
I started with WP E-commerce. When WooCommerce came out, I resisted using it for my web design and development, as I had some successes with WP E-commerce. Since then, the WP E-commerce team has changed people several times, and the development track is inconsistent to say the least. We had numerous clients who lost money from updates that were incompatible with the Get Shopped system. While initially WP E-commerce had more users and plugins, circa 2011, now WooCommerce has moved so clearly ahead it is no longer even a fair comparison. WP E-commerce was one of the pioneers of WordPress Ecommerce, which was really cool for those of who had only work worked with Zen Cart and osCommerce.
