Keeping track of word count when prototyping or developing content is important, especially in the context of today's ever expanding social platform criteria. Word Counter lets you easily count the words in your article, blog post or meta description in real time, and compare your character count to common benchmarks for Facebook, Twitter and Google. We're definitely down for this count.
