I hate when this happens. Let’s say that I’m a loyal visitor of your blog, I read it every day. You have posted a great but long article, full of text, pictures and even a little movie. And you didn’t split it! What if I enter the index of the blog and I would like to read the second article? I have to scroll down a little. This is frustrating.
If you haven’t noticed, wordpress (and maybe other platforms too) has a great thing implemented.
Don’t be afraid to use it! It will definitely improve the blog’s usability and you’ll see that your readers will be satisfied. So … when reaching about the middle of the article click on that button, and then continue writing. Publish the article and you’ll see the changes.
