There will be days when you sit down to write your blog posts and you find your mind being unable to click. This happens to everyone at one time or another, so don’t let it put you off blogging altogether. There are lots of different types of blog posts you can write, and many ways to come up with ideas for new articles for your blog.

Tip #1 – Keep a folder for blog post ideas.
Keep a folder handy where you can store material to be used in blog posts. This might include simply ideas that you have during the week, a link to a good website you have found in the course of your work, or an interesting post on another blog or message forum. You can also include information on any product you have used during the week so you can write a simple review in your blog.

When you are stuck for ideas delve into this folder for inspiration. It can give you some much-needed inspiration. Clear it out regularly and get rid of out of date information, otherwise searching through your ideas folder can be as difficult as coming up with a post topic from scratch.

Tip #2 – Keep spare posts or stub posts.
On some days you may find you have more time and inspiration than others. When this happens, try to write an additional post or two to be used on days when you have writers block. If you are writing a full post, make it generic and not time sensitive, otherwise it may be outdated by the time you want to use it. Alternatively write “stub” posts, or short summary posts, that can be expanded or fleshed out with topical information when you want to publish them.
