Installing AddThis to your blog on Blogger is easy. This visual guide will walk you through the installation process. First be sure to Get AddThis for Blogger, then follow the steps below.
Sidebar
If you'd like to place the button in your blog's sidebar, follow these instructions. Installing this button will automatically position the button in your sidebar (typically in the top right hand corner of your page). By installing it once, it will appear on all your pages.
Step 1
Click the Install to Sidebar button on AddThis.
Step 2
Click Add Widget, and you're done!
Blog Post Button
If you'd like to place the button below each one of your posts, follow these instructions. Installing this button will automatically put the button below each individual blog. This is the most popular implementation of the button for Blogger.
Step 1
Log into Blogger and select the blog you want to add AddThis to. Select Design > Edit HTML. These controls look like tabs, and they're located at the top of the page.
Step 2
Check the Expand Widget Templates checkbox. This checkbox is located in the top right corner of the page, above the code. By clicking the checkbox, the code in the field below will refresh.
Step 3
Copy and paste the AddThis code snippet into the template, right after the <div class='post-footer'> tag.
Note: If you have trouble finding this DIV, try copying and pasting the blogger code into a text file editing program and do a search for 'post-footer'. Once you located it, copy and paste the AddThis button code below the DIV. Then copy the entire text file and replace the code on blogger.
Step 4
Click Save Template, and you're done! A new page will load along with a confirmation at the top of the page should appear that reads, "Your changes have been saved. View blog." Click View Blog to preview your blog with the new AddThis button. The button should appear beneath each blog post.
