There are a few ways to automatically share blog posts on Facebook. The easiest way is to use a plugin like Shareaholic or B Social.
This will add a share button to the post, and you can click it to automatically post the blog post to your Facebook page. Alternatively, you can use a tool like Hootsuite to schedule posts to be shared at specific times.
The most important thing is to make sure that you are sharing your best content! Make sure that your posts are well-written, interesting, and useful. If you can, try to share posts that are related to current events or topics that interest your audience.
Social media is a great way to connect with your audience and build relationships. By sharing your best content, you can increase the chances that they will return to read your blog in the future.
