Wordcounter.net is a wonderful site that does just one thing: counts words (technically, it counts characters, too, but who’s counting? Well, I guess Wordcounter.net is…).
Why is this so important? Well, in SEO you need to know exactly how many words are in your meta descriptions, how many characters are in your Title Tags, how many words are in your blog posts, etc…
Other tools do this, and WordPress wysiwyg editor does it if you’re in default editor, too. But because there are many themes now that have a builder (like Fusion Builder with Avada, for instance), it’s nice to have a tool that will count your words and/or characters.
As a bonus, it does not change the format like Microsoft Word does, so you don’t have to end up reformatting.
