Facebook now lets you describe the posts you want to see, rather than leaving every preference to a like or a skipped video. The useful question is which problem you're trying to fix: irrelevant recommendations, a particular account you want to avoid, or simply missing posts from people you follow.
Those need different controls. The new Your algorithm feature can help with the first. It shouldn't become a reason to spend your evening writing increasingly elaborate instructions when a simpler feed setting would do.
In its October 13 announcement, Meta says Your algorithm is rolling out through the three-dot menu on Facebook posts. You can add and manage topics for Feed and Reels. The company is also adding written follow-up feedback after you select Interested or Not interested, so you can explain what worked or what you disliked.
Meta says recommendations can respond within the same session. That's a company claim, not a result we've independently tested. Its explanation also makes clear that written preferences join existing signals such as what you watch and engage with. You're supplying another input to ranking, rather than replacing the ranking system.
Pick the control that matches the complaint
For a feed full of the wrong topics, start with one specific change you can judge. If you want practical cooking ideas, for example, try asking for weeknight recipes rather than adding a broad interest in food. That's a suggested experiment, not a promise that Facebook will interpret the request perfectly. Look at whether the next recommendations are actually more useful before adding more instructions.
If the problem is one account, use an account-level control instead. The Facebook Help Center's feed-control guide distinguishes hiding a single post from unfollowing a person or Page. Unfollowing stops their posts appearing in your Feed; hiding one story addresses that story. A topic preference is a less direct way to solve either problem.
If you want recent posts rather than a personalized ordering, the company's ranking explainer points to the Feeds tab for a chronological view. It also describes Favorites as a way to prioritize selected accounts. Those options answer a different need from finding better recommendations.
The announcement doesn't give a country-by-country rollout timetable. If Your algorithm hasn't appeared for you, don't assume you've missed a setup step or that every account already has it.
The promising part is being able to state a preference directly. The test is whether that saves you attention. Try one clear adjustment for recommendations, use unfollowing for accounts you don't want, and choose Feeds when catching up is all you came to do.
