One option that many people don't think about is to use an article template. An article template gives you a general idea and then you have to insert the topic using the idea they suggest. For example an idea would be Methods for Saving X and a topic would be Methods for Saving Money. With most templates you will have the ability to do at least two articles from it until you can come up with more topics. The two articles would be a positive and negative or upside and downside. There are a number of places you can visit for article templates. Some of them supply free templates while others charge a fee for them. You'll want to do a Google search to see what you can find and use for your articles.
As a writer you know how difficult it can be to come up with article content at times. If you've ever had writer's block you know what I'm talking about. There are several things you can do to make it through the writer's block phase. One of the most popular is brainstorming with a friend or family member. Another option is to rewrite the articles and blog posts you already have written.
