Meta has published an engineering explainer on Your Algorithm, the Facebook control that lets people edit the interests shaping their Feed and Reels in plain language. The post, dated November 10, details how new interests are boosted, how unwanted topics are filtered by a fine-tuned LLM, and how quality requests such as less AI-generated content are handled. Social Media Today covered it the next day.
What the control looks like
The Your Algorithm page has three parts: a one-sentence Lately Summary, an Interested In list prefilled from past activity, and a Not Interested In list. People can add topics in their own words, move them between lists or remove them, and the changes apply to both Feed and Reels through a single shared preference store.
How the ranking actually changes
Each Interested In topic drives four retrieval sources, and adding a new one triggers an extra fetch outside the normal cycle. Meta says new interests get extra weight for a limited period, but a control layer spaces out and caps how much any one interest contributes per day. Meta did not publish the duration or the cap.
Not Interested In topics are enforced in ranking through embedding comparisons and demotion rules, then by a small fine-tuned LLM reranker that removes matching items, then on-device through cache invalidation.
- Quality requests (for example, less AI-generated content) map to demotion signals, not topic matching
- Naming a creator to see less of filters that creator's content directly
- LLMs generate the starting profiles and validate each edit
Who it affects
This is organic ranking, not the ads auction, and Meta gives no rollout figures or effect sizes. But it changes the context your ads appear in, and it affects any brand that relies on organic Reels and Page reach on Facebook.
Social Media Today notes the controls can reduce AI-generated content in Feed without removing it, and that ranking still follows engagement.
What to do about it
If your organic content looks synthetic, it can be demoted for users who ask for less AI content, even when the topic matches their interests. Keep a mix of real footage and clear human presence in organic posts, and watch organic Reels reach for step changes that line up with this feature.
What it means for you
- Organic reach on Facebook can now drop for users who ask for less AI content
- Creator-level requests filter a creator out directly, so frequency fatigue has a cost
- Ads ranking is separate, but feed context and organic warm-up traffic shift
- Use real footage in organic Reels to stay clear of AI-content demotion
