Authors get a whole lot of pressure from agents and publishers to promote their work on-line. Obviously an attractive and regularly updated website is a good idea. And if you enjoy blogging and posting on various sites, great. But most of us have so little time to write, much less do all that on-line promotion. We’re writers and writers need to, well, write! Margaret Atwood had very useful thoughts on this one in this link. She said “…if all you do is promote your own work, other people will think you’re vain and egotistical. They’ll be very happy to get recommendations from you about books by other writers, however.”
That last line of the quote is the key: promote the work of others to build community.

I’ve got this author website and it showcases my work, has a bio and pictures of me, and talks about what I do. Me, me, me. However, the best parts of this website are the guest blogs by other authors. So many perspectives, so much great talent. I send the writers I work with to these blogs all the time. The blogs are packed with good advice on craft and living the writers' life.
On a personal level, in contacting writers to do guest blogs, I get a chance to “meet” other writers and engage with other writers I know. On a community level, I get to promote the work of others.
The guest blogs help keep my site fresh. Once the guest blogs are up, the writers often post a link to my site on theirs and elsewhere. The blogs are picked up and quoted and then there’s more links. So, in the end, it's good promotion for me as well. But that’s really not the point. We’re building community and having fun doing it, sharing ideas.
So, community is everything, and never go anywhere without a gift.
Here’s where the gift comes in:
Marketing a book doesn't begin when the book is released. It starts months earlier. Keep in mind your editor is your champion at a publishing house. Editors are always overworked and underpaid and so a show of appreciation means everything. Send your editor a gift that has a meaningful connection to your book in some way. The editor may well show this gift around in house to generate excitement with others, especially publicists and marketing reps. If you can send along gifts for these folks too, then do. If you can send along more gifts, tools that that the publicity team and marketing reps can pass along to booksellers and media, then do that too.
In The Cure for Death by Lightning homemade paper and a scrapbook are featured. So, I made homemade paper scrapbooks and bookmarks for all these players. When I did book expo events I baked squares from a recipe in The Cure and handed them out. A Recipe for Bees was all about honey so we made hundreds of tiny jars of honey and shipped them out to my publisher. In Turtle Valley, photos figured large and my husband is a photographer, so we shipped out photos from the book that were passed on to booksellers and media

The landscape of the Shuswap-Thompson was the focus of The Spawning Grounds, so my husband and I put together postcards of the region with a personal note on the back of each. You’ll see examples of these postcards with this blog. My publicist showed these around in house and then tucked them into each ARC (advanced reading copy) for media and select booksellers. These were picked up in so many ways. People who received them shared them on social media. My husband also used these images and many more to create a trailer for the book.
Community is everything and never go anywhere without a gift. The key is to make that gift something genuine and meaningful, from you, and, of course, related to the book in some way.
But, in the end, the quality of the book itself is what sells the book. So, selling it starts way back, with craft, getting it right. If the writing is fantastic, readers will fall in love with it and pass it on. Hand sales are still everything. Now, though, those “hand sales” are done at vast distances, on the internet. If your book is great, the readers themselves will promote it. Reader reviews are where books are really sold. But only if the reader truly loves that book.
