The short version: Yes, Facebook keeps a watch history of every video you've watched or even paused on, including Reels, Watch content and video ads, and it's tucked away in your Activity Log rather than somewhere obvious. You can view it, delete bits of it, or clear the whole lot, but doing that won't stop Facebook's algorithm from already knowing what it needs to know about you.
Where to find it
Most people never find this because Facebook doesn't want you to. It's not sitting under a tab called "Watch History" on your profile. Here's the path on the app:
- Open Facebook, tap your profile photo top right
- Scroll down to Settings and Privacy, then Activity Log
- Tap "Watch history" (sometimes listed under "Logged actions" or "Filters")
On desktop, go to your profile, click the three dots under your cover photo, select Activity Log, then look for Watch History in the left sidebar under Filters. It lists every video you've watched, scrolled past for more than a second or two, or had autoplay on, with a timestamp and a direct link back to the video.
What counts as "watched"
This is the uncomfortable bit most explainers skip past. Facebook doesn't just log videos you deliberately clicked play on. If a Reel autoplayed in your feed and you watched three seconds before scrolling on, that can still show up. If you've got autoplay switched on (which is the default setting for most accounts), your watch history can include content you barely registered seeing. So when someone insists "I never watch that rubbish" but their watch history is full of it, the answer usually isn't that Facebook made a mistake. It's that autoplay did the watching for them.
Say you run a small events business and you've been scrolling Facebook during lunch, half-watching Reels while eating a sandwich. Three weeks later your feed is full of cooking videos and home renovation clips, because Facebook's algorithm quietly built a profile from content you'd swear you never actively chose to watch. That's not a glitch. That's the system working exactly as designed.
Why it exists in the first place
Watch history isn't there for your convenience, even though Facebook frames it that way. It exists to feed the recommendation engine that decides what shows up in your feed, what ads you see, and what gets pushed to the top of your Reels tab. Every pause, rewatch, and skip is a data point. Meta has been open about this in its own transparency reporting: video watch time is one of the strongest signals used to rank content, stronger than likes or comments in many cases.
This matters if you run a page or post content for a business, because it explains a pattern a lot of marketers never quite connect: videos with high early watch time get pushed harder, which is partly why short, punchy openers outperform slow builds. If you're trying to understand how reach and payouts connect to watching behaviour, it's worth comparing how this plays out across markets, like Facebook's pay per 1,000 views in Australia versus the UAE or Indonesia, where watch time thresholds directly affect what creators earn.
How to clear or manage it
If you want to clean it up, here's the step-by-step on mobile:
- Go to Activity Log, then Watch History
- Tap the three dots next to any single video to remove just that entry
- To clear everything at once, look for "Clear Watch History" at the top of the list, confirm, and it wipes the visible log
- Separately, go to Settings, Video and Photos (or Reels Preferences), and turn off Autoplay so new content doesn't log itself without your input
One number worth knowing: clearing your watch history does not reset your ad preferences or your "Why am I seeing this ad" profile, those are stored separately under Ad Preferences, and you'd need to clear that too if you want a fresh start. Most people clear one and assume the other is sorted. It isn't.
The bit nobody wants to say out loud
Clearing your watch history feels like deleting your browser history, satisfying, a bit of a fresh start. It isn't. Meta's ranking systems have already extracted the patterns they need from your behaviour well before you ever open the Activity Log. Deleting the list doesn't delete the inference. Facebook already knows you linger on property videos, skip past political content, and rewatch cooking Reels twice. That profile sits in the recommendation model, not in the visible log you just cleared. So if your real goal is "stop Facebook knowing what I watch," clearing the history gives you a tidier screen but not less tracking. The only things that meaningfully change the pattern are turning off autoplay, going into Ad Preferences and removing interest categories, or simply changing your scrolling habits for a few weeks so new signal overwrites the old.
A worked example
Say you manage a Facebook page for a local gym and you're trying to work out why your Reels suddenly stopped getting pushed to new audiences. You check Activity Log out of curiosity for your personal account and notice your own watch history is dominated by news clips and sports highlights, nothing fitness related. That tells you something useful: your personal feed behaviour doesn't drive your page's reach, Meta separates personal watch history from page-level audience signals, but it's a handy reminder of how specific this tracking is. If you were instead checking Audience Insights or your page's content performance tab, you'd see watch-time data for people who've engaged with your page content specifically, a completely different dataset to your own history.

This confusion between personal and page-level data trips up a lot of business owners who assume watching their own content "trains" their business page algorithm. It doesn't. The two systems barely talk to each other.
If you're managing this for a business
If you're running paid content or trying to understand audience behaviour rather than guessing, it's worth getting someone to audit the data rather than clicking through settings menus hoping for the best. This is exactly the kind of thing that comes up when businesses bring in an AI consultant for small business to make sense of platform data and turn it into something useful for targeting and content strategy, rather than leaving it as a pile of settings nobody checks.
And if your content strategy leans on trends like Reels formats or captions, it's worth knowing the language too, because misreading a comment thread full of IKR or POV-style captions can make your business page look out of touch fast, and that affects watch time just as much as any algorithm setting.
Frequently asked questions
Does Facebook keep a watch history even if I don't use Watch or Reels?
Yes. Any video you see in your main feed, including video ads and autoplayed clips, gets logged in Activity Log under Watch History, regardless of whether you ever open the dedicated Watch tab.
Can other people see my Facebook watch history?
No, your watch history is private to your account and isn't visible to friends, followers, or page admins. Only you can see it in your own Activity Log.
Does clearing watch history stop Facebook from recommending similar content?
Not fully. Clearing the log removes the visible list but the recommendation algorithm has already used that data to build your interest profile, so you'll need to also adjust Ad Preferences and turn off autoplay to see a real shift in what you're shown.
Does Facebook watch history include Instagram, since Meta owns both?
No, Facebook and Instagram keep separate watch histories even though both are owned by Meta. You'll need to check Instagram's own Activity settings separately to see or clear that data.
