WooCommerce – because it integrates into WordPress – comes with a lot of strong SEO features built right in. WordPress will give you feedback on your SEO right in pages and posts. This makes it easy to visually judge if your SEO on any given page or post is strong and also takes the pressure and thinking out of SEO. For SEO, it is certainly one of the best ecommerce platforms out there.
BigCommerce is most easily compared to Shopify. Both platforms offer a similar experience when building an ecommerce platform. Like Shopify, BigCommerce offers a range of prices and packages tailored to different types of businesses. The platform is highly customizable if you are comfortable with some light coding. It is also possible to use themes and templates to build your website, but some of these will come at an additional cost.
