The FIRST thing you should do on Goodreads...

Authors avoid Goodreads. They sprint past it like a child running past a dark room, as if they don't look, and don't pause, the monsters there might not actually exist. But just like the dark room with the imaginary monsters - there is nothing to fear about Goodreads. And actually ... that dark room is a treasure trove of free promotional tools and avid readers. 

The face of your novel...

It's no secret that book covers are important. For new authors, I'd say that they are one of the most important tools that we have. While the blurb might cause a reader to actually purchase the book, a reader won't even see the blurb if the cover doesn't cause them to click on the book.
