How to follow topics on X (and who can see them)

#Quick answer

To follow topics on X, open the more icon (your profile icon menu on mobile), tap Topics, and press Follow next to any topic. X also shows Follow prompts for suggested topics inside your Home timeline and search results. Topics are free, they change what appears in your feed and the ads you see, and the list of topics you follow is public.

#TL;DR

Topics are X's oldest personalisation lever and the least understood one. Following a topic pulls posts about it into your timeline from accounts you do not follow yet, which is a fast way to make a thin feed useful. Two facts are missing from almost every guide ranking for this: your followed topics are visible to anyone who can see your profile, and the 2026 way to get a proper topic feed is not Topics at all. It is Custom Timelines, which is paid.

#How to follow a topic on X, step by step

There are three routes in. All of them work on the iOS app, the Android app, and x.com in a browser.

From the Topics menu (the complete list):

1. On the web, click the more icon in the left sidebar. On mobile, tap your profile picture to open the account menu.
2. Tap or click Topics.
3. Topics you already follow appear first, with suggestions below them.
4. Press Follow on anything you want. Press the dismiss button instead and the topic drops into a Not Interested group you can reverse later.

In your Home timeline, X periodically injects a suggested topic card between posts, with a Follow button attached. One tap and you are following it.

In search results, run a search and X will often offer the matching topic at the top of the results with the same Follow control.

On someone else's profile, open their profile, tap the more icon, and select View Topics to see what they follow. Anything listed there can be followed from that screen. This is the most underused discovery route on the platform, because a good account in your niche has usually already curated the list you want.

Per X's help page on Topics, following a topic tells X to personalise your experience with "relevant posts, events, and ads." That last word matters and almost nobody mentions it: a followed topic is an ad-targeting input, not only a feed input.

#The part most guides miss: your topics are public

The topics you follow are not a private preference file. X states it plainly: topics you follow are public, and anyone who can see your full profile can view them through the more icon on your profile. If your posts are protected, only your approved followers can see the list, which is the only privacy control available here. There is no toggle that keeps your posts public and your topics hidden.

For most people this is harmless. For anyone using a professional account, it is worth thirty seconds of thought, because "View Topics" is a readable summary of what you actually pay attention to. If that matters to you, either unfollow the ones you would rather not publish or make the account private and accept the trade.

One more cap to know about: your Topics menu displays up to 100 followed topics at a time. If you have been tapping Follow on prompts for years, the real list is longer than what the menu shows, and the full version lives in Your X data alongside every interest X has inferred about you.

#Custom Timelines: the 2026 way to pin a topic feed

Topics has a structural weakness. It mixes topic posts into one timeline, so a strong interest and a passing curiosity end up competing in the same stream. X fixed that in April 2026, and it fixed it behind the paywall.

Custom Timelines, announced on 22 April 2026, lets you pin topic feeds next to For You and Following and swipe between them. The specifics, per TechCrunch's hands-on and Social Media Today's write-up:

To set one up, swipe right past For You and Following, tap the plus symbol, and choose your feeds. You can reorder them from the same menu. Two honest caveats from the hands-on coverage: the rollout started on iOS with Android following later, and the second slot in each feed is an ad, so the new surface came with new ad inventory attached.

If you are weighing the subscription for this alone, the full cost breakdown is in our guide to X Premium pricing. And if what you actually want is a chronological feed of specific accounts rather than an algorithmic topic feed, Lists already do that for free, and they can be pinned into the same swipe row.

#How to unfollow, snooze, or dismiss a topic

Unfollow from the Topics menu. Open Topics and tap the Following button beside the topic. Done.

Unfollow from a post. In your Home timeline, open the top icon on a post that arrived because of a topic and choose Unfollow.

Say Not Interested. Suggested topic prompts in your Home timeline and Explore tab carry a Not Interested control. Using it is better than ignoring the prompt, because it feeds back into what gets suggested next.

Snooze a topic. X shipped topic snoozing alongside Custom Timelines for Premium members on iOS and web, which temporarily quiets a subject on your For You tab instead of permanently unfollowing it. Useful during an election, a sports final, or any week where one story eats the platform.

Unfollowing is not a hard filter. X says it may still recommend posts about a topic if you keep liking or reposting that subject, which is the algorithm doing its job. Your behaviour outranks your settings, a pattern that shows up everywhere in how the X algorithm works.

#Interests and "Known For": the two settings behind Topics

Two deeper controls sit underneath the Topics menu, both inside Your X data.

Interests from X. Open Settings and privacy, then Privacy and safety, then Ad preferences, then See your X data, then Interests and ads data, then Interests from X. Deselect anything that does not reflect you. X will stop using it to personalise your experience and stop suggesting it as a topic to follow, unless you search for it specifically. X also warns that these changes take time to propagate.

Known For. On x.com, the same Your X data screen has a Known For tab. This is the reverse control: it governs which topics you can be featured in, not which ones you see. If X has decided you are a voice in a subject you would rather not be associated with, this is where you deselect it. Almost no guide covers this tab, and it is the one that affects how other people find you.

#Do topics actually help your reach?

Following topics is a consumption tool, not a growth tool. It shapes what you read, and it does nothing directly for your own distribution.

The indirect effect is real, though. A feed full of the conversations you want to be part of makes it far easier to reply early and usefully, and replies are still the cheapest reach on the platform. If your timeline is mostly noise, you will not find those conversations in time. Pairing a couple of well-chosen topics with a chronological Following feed and a List or two is a better reading setup than any of the three alone, and it puts you closer to trending conversations while they are still open.

Where it falls apart is consistency. A perfectly tuned feed does nothing if you read for twenty minutes and post nothing, which is what happens to most accounts by week three. X-Autopilot drafts your posts and replies in your voice from real Chrome on your own Mac, so your session cookie stays on your machine instead of passing through a shared cloud dashboard: a lower detection surface than cloud tools, not an absence of risk, and browser-route automation on X remains a gray area rather than a sanctioned path under X's automation rules. It will not pick your topics. It removes the reason a well-curated feed still produces nothing.

Follow four topics you genuinely care about, check what your list says about you in View Topics, and spend the saved scrolling on replies.
