DiscoverSnoop has the largest Google Discover feed monitoring network. Thanks to this network, we identified the first AI Overviews excerpts appearing in the feed in June 2025. Now, we can confidently announce that Google has begun pushing LinkedIn posts into the Discover feed. As you can see in the screenshot below, the feed includes the name of the LinkedIn influencer, an image, and a mention of βLinkedInβ as the source.

For now, these posts have limited visibility, and most do not reach the threshold required to be statistically representative. However, we have observed posts in German and French gaining traction and reaching view counts that indicate they have been widely distributed. Here are those posts as reported in the DiscoverSnoop interface:

The appearance of LinkedIn content brings back the question of Instagram and TikTok in the Discover feed. Here is what we can say at this point about these two platforms.
Regarding Instagram, DiscoverSnoop detected intermittent tests throughout 2025, from January to October. Our subscribers can find a list of all these tests here. On October 17, these tests ended. We captured both Reels and posts from Instagram influencers, with Reels being the most common. These tests show that Google engineers have already experimented with pushing Instagram content into the feed but have not yet rolled out this feature in production.
As for TikTok, we have not observed any posts so far, suggesting that things are not yet ready on that front.
