One of the most common problems that writers face is what to write about. To make good money, a writer would not want to spend a whole day researching one article and only get paid $15 for the article. It would
just not be worth the time. However if that research is on ad revenue sharing it could end up make over $100 for the day's worth of work, now that would be worth it.
Flat fees are nice because you know how much you will get paid for the article, while ad revenue is a bit of a gamble. You don't know how long it will take to get traffic or how long the traffic will last, plus you have to wait for the money.
All of this is very important when a writer is stuck and searching on what to write on. A writer could learn a new topic or write about current events; but a writer needs to be careful about the time spent to write an article and determine if the time spent was worth the pay. Of course this is looking at writing from a business stand point, not as a hobby. People who write as a hobby do it for pure enjoyment and the money is a nice bonus. Learning more is alway beneficial.
With all of this in mind what to write about is still the hardest part of writing. Looking back at some of your previous writing my help to spark an idea. Writing sites like Helium allow you to write on titles that are already preexisting. This can be a great help to find a title you can write on, simply search the web site until you find the right title.
Another great resource is reading. By reading you can improve your writing skills and possible strike an idea. Again with Helium you can read and rate articles. The more article you rate the more stars you get, starts equals out to better payouts. (Send me an email if you would like a referral link sent for Helium. I only get so many a year, but I still have some.)
Remember every writer gets stuck with writer block. This could be a sign that it is time for a break or short vacation. Sometime if you spend a week focused on "how to" articles, you just need to change your focus
over to another type of writing like short stories of poetry. This should help you overcome your writer's block.
Just a walk in the woods can help ideas to start popping in, so take along a small note book and pen. This way you'll be ready and not forget any ideas. There is nothing worse then having a good idea and forgetting
what the idea is.
If writer block still continues, you may need to step out of your comfort zone and write about a already created title. It may be more difficult to write, and you may need to do some research, but it may help to get the idea and creativity flowing again.
