Puerto Vallarta, Mexico - If you have written a book and you want to sell it, empowerment writer Donna Dahl will be providing a marketing formula at the 9th Puerto Vallarta International Writers' Conference March 6-8, 2015.

The author of three self-help books, Dahl will guide participants in the use of social media as a means of promotion. The conference, sponsored jointly by Puerto Vallarta Writers' Group and Biblioteca Los Mangos, will be held at the library.

"The use of social media is essential to publicity in communications today," she says. She suggests "learn one of the big five and take it from there. Finding the one you like can be a lot like swimming. First you have to get in the water. After a few lessons you decide if you prefer the breast stroke or the butterfly."

The focus of her presentation, she says, will be "learning the 5 Ws of Tweeting on Twitter in a hands-on setting." The sessions will involve small groups working over two hours in a lab setting with plenty of one-on-one assistance. Workshop participants should bring their own laptops.

Dahl is an annual visitor to Vallarta and a member of the writer's group. For more information, visit her webpage.

Texas writer Caleb Pirtle, author of more than 55 books, also promises to motivate as keynote speaker. Apropos to the conferences theme of 'Leaving Our Mark ... Awakening More than Memoir,' Puerto Vallarta's Maurice Monette, author of Confessions of a Gay Married Priest, will offer tips on memoir writing.

Other presenters - Sarah Cortez, James Callan, Thomas Pulley and Melissa Frost - will also offer an inspiring mix of seminars, workshops and interaction. Evelyn Byrne of White Bird Publishing and literary agent Elise Capron, representing the Sandra Dijkstra Literary Agency, will be on hand to consider manuscripts.
