I use this tool http://www.wordcounttool.com/ to count the words I have written before posting it as an article for any of my blogs. This tool is also essential for those who are into writing articles, or to those who are writing blog posts, both sponsored or not.
If you write a blog post, make sure it’s at least 50 words per post, especially if you want to build your blog’s reputation to the search engines.
There can be not much to talk about on your post. But hey, don’t just post a sentence. Well, sometimes it’s okay, like photo posts, birthday greetings, or maybe greeting holidays to everyone. But for ordinary blog posts, just make it a habit to make at least a 50-word post.
