Hello!

So after quite a successful career as a dating coach, I have finally written a book teaching guys how to get laid on the first date. I've set up my own website to sell it, but I am completely new at making sales pages that look attractive and convert visits to sales.
I might also look into hiring a professional designer/coder to make it better, because right now it was made in a simple WYSIWYG Web Builder. I also want to optimize it for SEO for certain keywords like "how to get laid, how to talk to girls, how to get a girlfriend". I've done the basics but I am not really super sure how to promote my Site effectively.

So what I should do to effectively promote my Site?
