Do you author a Google Blogger blog?
If you are not allowing for social media sharing, you should be. This will allow your readers to quickly post your posts on Facebook, Twitter, and other social media-- and allow them to easily reblog your content. This will increase your viewership.
It is very easy to do.
First, open your layout feature in "my blogs"
Then, open "edit" in blog posts.
Once you open edit, you will see this menu for configure blog posts. Make sure "show share buttons" are checked. You can also check "allow email of posts" if you wish.
Hit "save" on the bottom and close. You can also rearrange where the buttons go, but I just use the default location.
And that's it- you are now done!
