If you have posted content that you thought was going to do better than it did, you probably weren't using it in the right way. It's not worthless, there are ways that you can use this piece of content again to make it more useful. You can reach out to bloggers who have a customer base that is similar to what you are looking for. You can also use it for a Q and A so that you have answers to questions right there. Or, just use pieces of it in different, and relevant places on the web.
- If you have had a piece that you think should have received more attention, you relied on organic search too much.
- You can promote your content to more relevant bloggers and publishers to share.
- You can take your longer content and post pieces elsewhere to places that are more relevant.
"Good news: there are ways in which even non-viral content can be useful on your site and for your business goals."
