If you own website and you need to publish content on it then you probably will need character counter. I’ve used this character counter to measuring how long content I have and you could use it too.
Is longer content better?
In online marketing is one of old myth that long content is better for search engines. The truth is different. For users are much more important relevant informations than long content. Is great that you focus what user needs and focus on serving content in right way. No need to write content to make it long. Write it for user.
