Ability to manage products, and do do mass product updates, etc. For example, if we want to change the price of a particular line, we can open up a master product file containing all the product data for that line. We can then update a CDV file with the new pricing data and map the new prices correctly to the appropriate skus. This is a huge time saver.
Easy integrations with almost any third-party software product.
The ability to integrate with multiple third-party products is a key factor here. We integrate with our bulk email product and our product review engine which eliminates much manual work and dramatically increases efficiency.
Allow configurable products (e.g. the ability to offer a specific item but with options, like color, available in a drop-down menu) as well as simple products with no options.
Easy CMS management system for data entry and landing pages.
Effective search engine optimization. When you create a product, the system creates a URL. Some CMS systems create meaningless URLs that are just strings of characters. Magento creates SEO-friendly URLs that contain the product name. For example, the URL format is of the format: store name/product name/sku. This is critically important for search engine optimization.
Power Reviews. Review system it complied reviews from reviews from other reviews.
It was quite easy - particularly the integration with PowerReviews. we just had to comment out the code to indicate where the reviews go. They provide a code snippet to help with this and the entire integration to less than a day to complete. Integration with ExactTarget was a little more difficult as we had to set up automations and different feeds, but it was still relatively straightforward.
