If you have a headline that says: “How to write great blog posts,” does the related article actually teach your readers how to write great blog posts? Or is the majority of the article about why your readers should write great blog posts – with a few, vague suggestions on how to do that at the end?

If you delivered little or none of the information you promised in the headline, your readers will feel misled and frustrated. Keep your readers happy: Make sure your headlines accurately represent your content.
