Short story sites are a great way to get people interested in your site. It is important to write many stories and get them out. This provides links to your website and also build credibility. Self published authors should definitely check this out. If you self published your own book getting exposure is one of the most important ways to do this. I recommend online if you are self publishing via Amazon because you can link everything together making navigation for your readers easier and buying books easier.
Post them here.
Here are some great links I found, best to worst.
