Pro Tips for Power Users

I've been usingFast Word Counter: Count Words Instantly Onlinefor months. Here are three tricks that save me time every week:

• Try it as a readability checker.Long paragraphs = poor UX. If your paragraph count is low relative to your sentence count, you're writing walls of text. Break them up.
• Check your keyword density.If you're writing SEO content, paste the text in, look at the word count, and manually check how many times your target keyword appears. No need for a separate keyword density tool.
• Try it for tweet threads.Twitter's 280-character limit is annoying. Write your thread in a text editor, paste it here, and trim each tweet to under 280 characters using the live counter.
