To submit your post to blogs, the first thing to do is see if your target blog runs guest posts. Many do not. They may state this on their site, or you may need to search their archives to find out.
Next, as with print, familiarize yourself with the blog. Look at the content they post, the length of the posts, and the writing tone. Try to match those characteristics.
They may post their submission guidelines, or you may need to email them and ask how to go about submitting a post. Follow their expectations exactly.
Then before you submit your post proofread it carefully. Then email it to them.
I wish you the best when you submit your posts and articles to blogs and websites.
