Complete Tutorial: How To Share Blog Posts to Facebook and Twitter

Sharing your #blog posts on social media is a great way to build up your network of followers.
Weebly makes it super easy to do that using the various sharing options built into the blog editor.
Sharing Scheduled Posts
You can set up sharing in advance when scheduling a
post to be published at a later time. While in the blog
editor, click on Post Options.
Choose the date and time you want the post to go
live and then click Edit Share Settings.
You can share to Facebook or Twitter, or turn them
both on if you like. You can also add an optional
custom message to go with your posts here.
If you have never connected to Facebook or Twitter
before, you'll need to authorize Weebly in order to
share. Go ahead and follow the prompts to continue.
After you've finished, click the Schedule button to
complete the scheduling process for your post. Your
post will be automatically shared according to the
options you chose.
Reader Like and Share Buttons
Your readers can also share or like your posts on their
own social media pages. We provide Facebook and
Twitter buttons at the end of every blog post for this
purpose:
You can turn off the Facebook or Twitter buttons, or
turn them both off if you don't want to use this
feature. Go to Settings > Blog > General and click
Customize next to the Post share buttons option to
toggle Facebook or Twitter on and off.
If you change your mind at any time, you can always
disconnect from Facebook and Twitter.
