Stop blogging on someone else site, Blog from your own website, send people to your website with your blog posts, don’t send them somewhere else. Businesses don’t send people to other sites, they post links for their own sites, so should you.
Your blog or news from your own site is a good way to become the authority on what is going on in your city. People will begin to visit your site for the actual news and what is going on instead of reading in on someone elses site or social media. You know best what is going on so why aren’t you updating the public from your own website?
