Get thee to goodreads, go to 'explore' >> 'listopia' and find relevant lists and add your books to them. Drop me the links and I'll vote you up too. I'm sure there's others here who can also help.
Get thee to Amazon and start making lists, and make sure your books are on there. Add other books that are also relevant and [i]deserve[/i] to be on those lists, because the more authorative the list, the better the recommendation for your book.
Do some googling. Find out where your target audience congretate - I know in my genre there's certain forums and groups that are very, very active in recommending and promoting work and if you get in with them you're home and dry.
How are you on short fiction? Could you write a 10k spin-off of one of your existing books? If so, do it and list it on SW for free. Make sure it can stand alone, but at the end you can put in a bit about the book that inspired it. Gives people a chance to see what you can do and whets their appetite for more.
Even sneakier... get thee to Wikipedia and cite your book in articles on your genre - e.g. "a common narrative trope of this genre is the strong female, such as XXX from XXX." Hyperlink to your book!!
If your book is available in paperback then maybe think about running giveaways on goodreads or on a blog hop (of genre-specific blogs). It'll cost you the price of the book but play GR right and you can get thousands of people entering - they will add the book to their TBR lists and some of them will go on to buy the book.
Do you know any other authors in your genre? Preferably successful ones... if so, creep creep creep until they agree to put a little promo in the back of their books for yours. You can always return the favour / do a feature on them on your blog, etc.
Speaking of the blog, if you do know any movers & shakers in your genre, badger them to do an interview or a guest post on it. Then when people search for them they'll find you
All the best Kitty. I'm starting to think it's the genre I write in that's the problem
I took a look at Wiki, and added on a link to an article about motorcycle clubs, but I' m not sure what I was doing or if I should be sneaky like that. It feels wrong to promote my book, on someone 's article, that's promoting a film, or book in the same genre.
I will be adding my book to more Goodreads lists today and I made my own on Amazon. ( even found one of my books on someone's list) Have also added my url's to Google.
niche genres are always difficult, but if that's what's in you to write then stick with it. perhaps try advertising it as a sub-category in a bigger genre? urban thriller or something?? maybe make up a genre for it that sounds exciting!! I don't think anyone makes it overnight just through networking however well they do it, you've got to build it up long-term and then get lucky.
