This documentation covers how Blog Actions work.
Applications that support Blog actions:
Blogs have readers of varying ranges of technical competence, from running thousands of contests across blogs we've found that readers really appreciate good instructions.
This will mean the difference between someone completing an action without actually leaving a comment and someone actually commenting.
Here's a good example of instructions from one of our first beta testers that gets great results from blog comments:
You can ask a user to comment on any blog post, on your own blog or on someone else's blog. You must require that they give you a way to validate the comment actually happened. Usually this is the name they commented under.
You can ask a user to write a blog post. Simply specify what you would like them to write about. You must require that they give you a way to validate that the post exists. The best way to do this is to ask for the URL of the post (which we prefil for you automatically.
This action will look for a valid blog post URL, submitting a domain only will not work. It always looks for at least a sub folder (i.e. yoursite.com/blog-post).
You can ask a user to subscribe to any RSS feed. Simply include a link to the feed inside the description. You can only ask the user to subscribe to one feed at a time.
