If you looking for best e-commerce website solutions than Magento is one of the best in it, its a ow-some and powerful also open source, and good for SEO, you can build it what ever the way you like for the Store.. Magneto Modules | Magento Extensions
I really think all of the most popular carts are going to be somewhat equal on the SEO factor due to the additional plugins you can add, the way you can edit the core files and you're true knowledge of SEO.
bigcommerce is the best. i've been with oscommerce, magento, shopify, magentoGo, volusion, opencart, and even prestashop. zencart is a variation of oscommerce. I would rule everything out, if your not going to go with BigCommerce, go with Magento (but theres enormous costs that most newbies don't realize) trust me, i've experienced it. I do offer ecommerce services, but PM for more details, I'm not trying to sell you anything, I just want to give you a advice that no one gave me
I use core commerce as my shopping cart platform. It is quite nice and will auto populate ares were the meta tags and descriptions are not completed. It has many seo features built right in and is quite easy to use.
I use Magento for my site handbagsmart(dot) com and oscommerce on my site dropshipdeals (dot) com. I like oscommerce much better
