In Sked, you will find the "Website or product URL" box displayed when you are uploading or editing posts:
What happens with the URL you enter depends on the social network you are scheduling content to. If you're scheduling to multiple social networks at once, we'll treat each link as appropriate for each social network.
For Instagram posts
On Instagram, users can't click the links included in a caption. As a result, we will not add the URL you enter to the end of the caption (like we do for other social networks).
The link for an Instagram feed post will instead be used in your Sked Link gallery. You can see more about Sked Link and how to set it up here.
Swipe up links were previously supported but have been removed by Instagram. We’re currently working on the ability to add link stickers. Until then, to add a link, post your story manually and save the URL to easily copy/paste.
For Facebook, Twitter and LinkedIn posts
We treat the link differently depending on the type of post that you are making to these social networks.
If you are making a 'text post' with no images/videos attached, we will add it as a 'rich link' alongside the post:
If your post has images or videos included, we will append the URL to the end of the caption that you have entered. This means you should not include the URL in the caption as well as the URL box, or you'll see two links at the end of your caption.
Here's an example:
