The social media network is the latest to add algorithmically recommended posts from all across its network, adding to the amount of content that it can deliver to users in-stream, and now introducing new 'Suggested Posts,' which will be highlighted to you based on your interests.
As LinkedIn puts it:
"In the past year, we've seen a 2x increase in people engaging in posts sharing knowledge, ideas, and support.". There are so many rich conversations happening across LinkedIn, but it is very hard to know what you are missing unless you follow the right conversations. To help you discover more relevant content that you might not otherwise know about, we are testing Suggested Posts in your Feed. With Suggested posts, we will do the heavy lifting to discover what's trending amongst professionals in your field and bring great conversations on topics that might be very relevant to you." 

As you can see, here in this example, suggested posts will appear with the 'Suggested' label in your feed. Here, LinkedIn's algorithm wants to highlight content that may interest you, based on your engagement activity.

This would effectively mirror TikTok's lead in the expansion of content recommendations beyond your social graph. On TikTok, focus is on the content itself rather than the people you decide to follow. This enables TikTok's algorithm to point out top-performing content from the entire platform rather than limit what it can show you based on your own manual selections.

This leads to much higher engagement and a far more compelling feed-that's why Meta and Twitter are now trying to squeeze more recommended content into user feeds as means to boost discovery and keep people scrolling for longer.

Although it would seem to also eliminate the need for a feed algorithm of reason. Both Meta and Twitter implemented algorithms so only the best, most interesting posts were shown each time you logged in since the user eventually ended up following so many people and profiles that showing that content in chronological order no longer had meaning.

But now, they are placing even more content from profiles that you are not following. Sounds like that is going to mean that you will see even less of the content that you have decided to see in each app.

Regardless, the huge engagement on TikTok has made this feature more appealing to almost every other app, and LinkedIn is no exception and has thus become interested in catching up with the action.
That might be interpreted as meaning that the posts on LinkedIn are able to reach whoever might be interested in whatever you are posting about. It is not yet possible to say what kinds of additional boosts these posts get, but it may perhaps be something to monitor throughout the coming months.
