When I started out writing articles they actually began life as blog posts. I wasn't very confident back then and didn't have the slightest idea of how to write articles and pitch them - not that I thought that any of my ramblings would be of any interest to editors anyway. I did send small articles to The Link - NAWG's (National Association of Writers' Groups) publication. There was no money in it, but a brilliant opportunity to hone my writing skills and get published.
It was a comment by one of my writing friends that set me on the path to making money from my writing (the cheque is in the post to this person, honest......) He said that my blog postings were the right style for writing Magazine. So I took courage, sat down and edited the blogs and came up with some pitches and subbed them. It took a while, but eventually I had my first article accepted and published in there, followed by many others and in other magazines too.
Then I had a series of articles accepted by Writing Magazine on writing groups. Now I've had a two part article accepted by Writers' Forum. I don't think I ever thought I'd get one article accepted let alone a series or a two parter! But I did and it took patience and a lot of hard work.
When the idea for an article comes into your head do you ever think you could expand it into more than one article. It's well worth exploring this before you pitch a single article idea to the editor. They like ideas they can expand - it encourages readers to buy the next magazine if they read an article in one issue that has part 2 coming next issue!
Make sure your pitch outlines why it would make a good two or three, or more series and show your plan for each instalment and how each article progresses and moves on smoothly to the next article in the series. Each article should be able to stand alone yet, link in effortlessly with all articles within the series. Also it pays to get quotes from different people for each article to enable readers to see the theme from different points of view.
It takes a lot of planning to get an article series accepted but with some thought and time it's not an impossible task.
