If you are using a Summary Block, and linking it to a blog post, there might be times where you are using the “Source URL” otherwise known as the “Post Source URL” to allow the summary block to link off to a third party link.

If you want this to open in a new window / tab, then you need to simply add the following to the end of the URL…

/"target="_blank

Before - Opens in the Same Window:

https://madebydave.org

After - Opens in a New Tab / Window:

https://madebydave.org/"target="_blank

You will need to toggle on the “Link Post Title to Source URL” for the link to work generally.
