Content quality matters. That's why we are always told that "Content is King" when we are building our online business.
Remember, we are building a business and our goal is to get more visitors to keep coming back to our website. Hence, it is important that we meet their needs by giving them varied quality information.
You want your visitors to read new stuff and see new updates from your websites. This is why choosing your niche is very important. You are encouraged to choose one that you are passionate about so that you can write quality content.
Your aim could be more than 1,500 words per post. But each one does not necessarily have to be of the same length. More importantly, give a thorough exposition and write as natural as you could be.
Keep your cool and let your audience enjoy a variety of your posts!
