Optimize your site for Social Media

From your dashboard hover over the word "appearance"
Choose "Customize"
Select "Social Media Networks"
- add your links and delete out any placeholder links.
Publish your changes
test your links by clicking the social media icons in the header or footer of your site

Change or fix link preview image for your home page

On your home page and your other customizable pages, look for "featured image" on the right hand side bar.
This isn't visible anywhere on our site, but when you share your home page to social media this photo will show up in the preview box.
If you already have shared your site to Social Media, Facebook may not automatically update to correctly show your new "featured image". To manually tell facebook to get your new "featured image" use the open graph debugger.

The homepage description automatically pulls in your "Site description" and "Title".
- To update, go to your site dashboard
- Go to the Appearance menu, and choose "customize"
- On the next screen choose "Site identity"
Once you've made changes you may have to manually tell facebook to "re-scrape" your link info by using the open graph debugger.

Here is the open graph debugger screen

On your blog post or custom page, look for "featured image" on the right hand side bar.
The featured image will be used for the "post thumbnail" as well as the "link preview" image when sharing on social media.
To update your link preview text add a post "excerpt" - scroll down to the bottom of the page and look for the "excerpt" box
If you already have shared your site to Social Media, Facebook may not automatically update to correctly show your new "featured image" and excerpt text. To manually tell facebook to get your new "featured image" use the open graph debugger.
Enter your link in the facebook debugger and click "Scrape Again"
