Put links in the post, not comments
Tom Orbach published a Marketing Ideas post on August 4, 2026 arguing that placing URLs directly in social posts (rather than comments) improves visibility. He cites an example where Mark Zuckerberg put a link in X comments and notes LinkedIn’s default “Most relevant” comment view can filter out comments containing links. Orbach points to his own viral LinkedIn posts that included URLs in the post (one receiving 333,343 impressions) and recommends marketers stop hiding links in comments.
Tactical guidance about organic social posting; useful for social marketers but not a platform policy change or industry-shifting development.

LinkedIn now lets you set post URLs
The newsletter reports two actionable shifts for marketers: ChatGPT has reprioritized official websites when answering queries, causing Reddit citations to plunge (reported drop from 3.8% to 0.5%), which increases the importance of brand-owned pages (pricing, competitor comparisons, and succinct FAQs) for being cited by AI. Separately, LinkedIn constructs post URLs from the first line of text by default but provides a hidden option to override and set a custom URL — a small, free change that can improve search and AI discoverability. The author links to an AEO playbook and data supporting these observations.

Threads tests Gems to honor valuable posts daily
Threads is testing a new feature called Gems, which awards up to 25 outstanding conversations daily with a visible diamond badge. The selection is algorithm-based, focusing on originality, timeliness, and authentic discussion, regardless of follower count. Posts or direct replies qualify, but reposts and content cross-posted from Instagram are excluded. The feature is currently limited to public US-based accounts of users aged 18 and older, though the badges are visible globally, including in Germany. Recipients get a notification and can share the badge. Users can hide the label if desired. Initial hints appeared in August via app researcher Alessandro Paluzzi. Threads aims to encourage original and engaging content, with no negative impact on reach for non-recipients.
