Blogging sites are that sites which let you submit your blog, Blogger, wordpress, weebly are the most common blogging sites but they are not that easy to use. If you want to start blogging in 2021, I suggest you to start with gopoco, it is the free blogging site and let you submit your blogs, articles and guest post. It is very easy to submit blogs at gopoco, you have to just create account and create your first post and you are all done with it.
