One thing they always say about great content marketing be consistent.
Deliver content consistently - whether it's an image, a blog or a full-on white paper. It doesn't matter what you're doing, it has to have a plan, a strategy, a structure.
So what do you do when, as seems to happen to everyone, the content simply dries up all of a sudden?
Secondly, put something up. Whatever you can think of posting - pictures on Facebook or a new blog post, just get it up there quick. It's vital to get the balling rolling again and it's amazing what a little momentum can do.
Thirdly, make a content plan. It doesn't have to be too fancy - don't try walking before you can run. Just figure out what went wrong before - usually the reason people just stop writing content is because they had no real plan in the first place. Think at least a couple of weeks ahead and work out roughly what you're going to produce or post.
Fourth and finally, don't neglect your customers. Ultimately you need them more than you need a blog post to go up. So if the pressure is on, prioritise - just don't prioritise content production completely out the window.
