Why are my YouTube recommendations so bad?

Last reviewed: October 8, 2026 · Markdown version

Usually because they are built from what your account did, and what it did is not always what you want. YouTube says its system “analyzes each viewer's profile in real time, which considers device, time of day, and past habits to surface and rank the most relevant content” (YouTube Help: YouTube's Recommendation System, read 8 October 2026). Every stray click, borrowed session and forgotten subscription is part of that profile. The good news is that YouTube also documents which of those inputs you can change.

What YouTube says it learns from

The same page splits the inputs into two groups. The first is watch history, and it covers more than what you finished:

“what videos they choose to watch, ignore, or dismiss ('not interested' feedback), how long and how much of a video they watch, and other viewing routines”
“content they've searched for or engaged with, such as likes, shares, comments, 'not interested' feedback, and survey responses”
“channels a user subscribes to and the languages of content they consume”

The second it calls interest affinity: favoured “themes, topics, and formats, as well as what's popular among similar audiences”, including what “similar viewers also enjoyed” (YouTube Help: YouTube's Recommendation System, read 8 October 2026). Separately, YouTube's recommendations page says it “may also use data from your Google Account activity to influence your recommendations” (YouTube Help: Manage your recommendations & search results, read 8 October 2026).

YouTube states the system's goals as helping “each viewer find videos they want to watch” and maximising “long-term viewer satisfaction”. It does not say how much weight any single input carries.

The usual ways it goes wrong

Our reading of that list, not YouTube's diagnosis:

One-off viewing counts as interest. A video you watched once for a reason, or out of curiosity, is still something you chose to watch. YouTube itself gives the school-project case as a reason to pause history: “when you're researching a subject for a school project that you aren't personally interested in” (YouTube Help: Manage your recommendations & search results, read 8 October 2026).
Someone else used your account. A partner, child or guest watching while you are signed in leaves their choices in your history.
Old subscriptions still count. Channels you follow are named as an input, so a list from five years ago keeps describing who you were then.
Similar viewers pull in things you never searched. That is the interest-affinity half working as designed, and it is the half you can steer least directly.

One case is not bad recommendations but none at all. The watch-history page says that with “no relevant or significant recent watch history” and history turned off, “recommendations on the YouTube homepage are removed”, and that this “applies if you are a new user before watching any videos” (YouTube Help: View, delete, or turn on or off watch history, read 8 October 2026).

The fixes YouTube documents

All from the recommendations page cited above, in rough order of how much they disturb:

Not interested on a video, or Don't recommend channel on anything from a channel, via More beside its title.
Liking, disliking and removing liked videos, since “Your recommendations and search results are also based on videos that you've liked.”
Show fewer Shorts from a grid of Shorts on Home, in the app.
Topic chips on Home and watch pages, for when you only want one subject for a while.
Removing single videos from your history, or pausing or deleting it.

The last one has side effects worth reading first, and our reset page walks through them. For a single channel you never want to see, the blocking page sorts the controls by what they actually stop.

The subscriptions input

Of everything on YouTube's list, your subscriptions are the input you can review in one place. SubSense does that review on your phone: it sorts the channels you follow into categories and shows which have gone quiet or flood your feed. You pick what to drop and approve every removal, and Undo re-subscribes you and puts the channel back in its category. Be clear about its reach: it reads your subscription list and each channel's upload dates, nothing about your own viewing, and it has no recommendation controls. And since YouTube's own description of the system does not say how much subscriptions weigh against everything else (YouTube Help: YouTube's Recommendation System, read 8 October 2026), nobody can promise how far Home will move. The app runs on iPhone and Android, and as an independent tool it is not affiliated with YouTube.
