One of the hardest things to do as an 'Independent Author' is to keep yourself in the public eye, but there are two relatively easy ways to do so: articles and columns.
Writing articles on publishing isn't too difficult, especially if you do something that others don't, but getting them published is. So how? Ask. Email editors with a proposal and see if they bite.
Some time ago I approached the ACW magazine with an idea for an article. I planned to write about converting a book to the Kindle format and uploading it to Amazon. The editor liked the idea and asked me to write it and after submitting it, said she'd publish it.
Since the book launch I've written a piece for the local newspaper, and I'm waiting to hear back from another magazine about an article on the launch. Small bites, but it all helps.
Columns are more problematic as they require an editor to agree to publish several articles over an extended period of time. As it happens, I proposed an idea for a monthly column about self-publishing to WritingRaw.com and they jumped at it...in a nice way of course and it goes out on the first of the month.
How did I get these openings? I asked. I am also a member of ACW and have been reading WritingRaw for a couple of years which made it easier for me to propose the ideas as I had a good idea of what they wanted. Do you have any magazines about writing that you read on a regular basis that you could submit an idea to? A website you go to on a regular basis, an online magazine?
Just ask. Editors are used to people submitting ideas on spec, for most of them it's how they fill each issue, and if they are interested and publish the article, then it'll be easier the next time as you'll be a known quantity.
I've yet to have anything commissioned for payment, but every article keeps my name in the public eye, not to mention the writing experience it gives me.
Go email a friendly editor...or even an unfriendly one, and surprise yourself.
