2. Ghost has SEO & social built-in
What’s the point in publishing if nobody reads your content?
Ghost has the best support for search engine optimisation and social sharing features of any blogging platform in the world. You don’t need any extra plugins or extensions, and you don’t need to write any extra code. It just works.

There are built-in XML sitemaps, Google AMP pages, canonical tags, optimised URLs, microformats, Facebook Open Graph tags, support for Twitter cards and clean semantic markup. All of this is done for you automatically, with no plugins needed.
3. Automated publication setup with Ghost
Getting up and running with WordPress, for the uninitiated, can be a long process. You have to download the software, find a hosting company, sign up for a new account, and then get all your files uploaded over FTP and setup a new MySQL database before you actually get to the install process.

Because Ghost offers an official hosted service, you can have a new blog up and running in the space of about 3 clicks – with exactly the same level of control as if it were hosted anywhere else. Powerful automation simply saves you a lot of time.
4. Ghost is faster
Because Ghost is powered by a modern technology stack using Node.js – it’s fast. Really, really, really, ridiculously fast.

Independent tests have found Ghost to be up to 1,900% faster than WordPress. What does that mean? In the amount of time it takes WordPress to respond to 1 request, Ghost will have already responded to 19 of them. The speed of your blog impacts everything, from search engine rankings to mobile user engagement.
5. Ghost is more affordable
We’ve built the best hosted service in the business, called Ghost(Pro). It’s comparable to running WordPress on a fully-managed hosting service with a dedicated Content Delivery Network.
You get the same incredible infrastructure and fantastic support, whether you currently receive a few thousand views or you're already up to tens of millions. But, you get all of it at a rather more affordable price-point:

"We’re using Ghost’s Pro service to host the blog for us. Works really well. Great writing experience compared to WordPress. WordPress is an incredibly powerful framework but because it supports the needs of so many websites and demands, it has grown into a sizable and cluttered tool."
