I'm a marketing and PR person, I'm happy to give advice

Hello,

I've worked as a freelance marketer, for marketing agencies and now for a PR agency. I'm also a journalist, blogger and hopefully one day I'll be a novelist myself!

Admittedly I haven't ever worked in publishing or book promotion but the stuff I know is easily translatable. So, if you want to know about SEO for your website, general marketing techniques, how to get your book featured in newspapers/magazines/blogs or just have any questions about something you are trying to put into action then I will try and help to all of my abilities!

As a phrase the search engines would just count instances of 'fantasy novel' together. 'Fantasy' and 'novel' would be counted a single keywords.

So, I'd suggest using it together. Because it's more specific, more like what a search engine user would be typing in.
