Strange YouTube watch-tracking behavior

Just looking for some indication that I'm not going a bit crazy here, but does anyone else get shown videos they've never seen before, indicating that the video has been partially watched?

It seems to be just on search results and recommendations and it picks random points in the video to be kick-off points for continuing.

If anyone has an explanation that'd be appreciated, as it almost feels like my watch history is getting mixed up with someone else's.

    This happens to me, in two different scenarios

    There's one that's somewhat infrequent, but sometimes YouTube seems to track how long a video plays when I hover over a thumbnail. And will bring me back to where I stopped if I ever click on that video in the future.


    There's other times where, like you, I find a video through search and YouTube starts me somewhere in the middle of the video.

    My assumption was that this was YouTube's attempt to guess the most relevant section of the video to my query, and jump me straight there. I know this was a thing on Google Search when you searched for a video, so I assumed that YouTube might've been extending that behavior more broadly.

            You may be delighted to hear that there are plenty of browser extensions to improve YouTube experience. The most well-known ones are uBlock Origin, SponsorBlock, and DeArrow. There's also YouTube Anti-Translate for those who sometimes get video recommendations where YouTube decides to translate the title into a different language. Those are the ones I know of; I'm sure there are more that cover smaller annoyances.

    Watch history has been working pretty poorly since hovering over a YouTube thumbnail, or simply having it on screen (on mobile) starts playing the video. My best guess is that that's what you're seeing.

    It also counts and keeps track of history if you click through the preview.

    This happens to us, and we assumed it’s 100% because of our AppleTV not shutting off every time we turn off the TV. I’d be interested to see what others have to say.

    Yes! This does happen to me and I've never been able to fully explain it! I never have autoplay enabled, so I never automatically get taken to other videos on any device, nor let videos play in such a way. I'm very picky and intentional about what I choose to play and how-so

    I have thought, at one point, it was due to my mouse hovering over a video in a results list or sidebar, and it starting to play a video in the thumbnail- however this was quickly disproven by the fact that a number of videos that I've never played that showed as partially watched were significantly long and indicated that I had watched an hour or more of them. Unless hovering (even for a split second when scrolling a page) causes it to scrub to a particular place in the middle of the video, and even if that's done for a second, it considers said video 'watched up to that point', but that seems wild and implausible to me.

    I do use a number of browser extensions, including some that help remember my place in videos without Youtube's help, or modify Youtube in certain ways, and I thought maybe some bug from them could be interfering, but it would not explain me seeing videos I've never even browsed to or searched for previously marked as partially-watched. There is also no common denominator between the various videos that have been "watched" that I've never watched, no common theme or content, or anything.

    It's always a search result or recommendation, and it always seems rather random.

      I have recently started using similar extensions, but disabled any independent tracking behavior. I also have my watch history only last 3 months, so it's possible to scroll back to that point and the video doesn't appear (that I can see anyway). Very odd.

      I've also disabled the autoplay preview, since it bugs me, so that can account for some I imagine, but l like you said it can't explain them all.

      *Oh should say, this behavior started before I used extensions/modified apps, from what I remember.

    I've been seeing videos I briefly clicked into and then saved to a playlist to watch later show up as partially or almost completely viewed when they shouldn't be. I mostly watch YouTube on my phone, followed by my tv, so I just assumed it was a bug in either/both of the apps. I've seen it in other streaming apps like HBO Max as well.

    If the other responses haven't convinced you yet, you're not crazy.

    The same has happened to me off and on for maybe more than a year now, in videos that show up in my search results for queries that I know I haven't looked up before and for videos that I have no interest in and thus wouldn't ever be in my results. I don't use YouTube signed in, I don't have browser cookies, I have various anonymizer features enabled, and I use VPNs, so I figured my activity was occasionally getting lumped in with someone else's somehow, but I guess it's more likely to be a bug or some half-implemented feature behind the scenes.

        For me YT will only track videos as watched during the same browser session. I do use a dedicated browser container for Youtube though, and if I close that all of container's tabs and go back to YT, there's no history.

      Yeah, glad it's not just me. By the sounds of it YouTube is quietly pushing search results that start at a 'highlight' or relevant section of a video.

    I have completely disabled watch history for a long time now and YouTube has become way, way, way less painful to use as a result. I highly recommend giving it a try. The main annoyance (for me) was having to remember where I left off in longer videos if I wanted to resume later, but if that feature is as broken as this thread makes it sound then maybe that's for the better anyway.

    YouTube search has been busted at this point for a long while and I can't tell if it's because Googles search is so debased to sell ads that it's hitting their other internal services. Or because YouTube scale has hit a critical mass of poorly sorted content over time that conventional search systems are ineffective. But they would rather die maintain the broken system than give users better search controls and finding what they need. Same thing happened with Drive: they need to maximize the users time on the tool to justify existing so sorting and content controls seem maliciously bad.

    I don't really mind it in Recommended and I think it's true to the function of that feed. Recommended is videos you would most likely watch. Subscriptions are for the channels you want to be informed had published something.

    My guess with Recommend is that youtube has some segment of the algorithm in place to promote content from new/small creators and another that will just roll a stack of dice and point you to vids gaining traction with demographic groups you marginally apply to. I don't really mind and I've recently gone down and Advertising/Marketing rabbit hole. Last one was essays on weird video game obsessions. Any Austin following infrastructure in open world games and Internet Pitstop gushing about Vibes for hours makes for fun background listening.

    Can't speak to the random start time. I know mine does that because my kid is only allows to watch YT on my profile. I think the app has device profiles because I get different recommendations on TV and my phone.

      That was my first impression too, I only questioned it once the video also started playing at the marked point, obviously not something a thumbnail can do.

    Note: all of this is with watch history disabled, and has been for months

    So to add another point of data here, I just did a search today, and a result of a video only posted 9 hours ago came up and showed as if I had watched almost 6 minutes in of a 16 minute video. This is not a search topic I've searched in weeks/months, and certainly not in the last 9 hours.

    I notice in the thumbnail of the result, there are almost "two progress bars", one is the one that shows my supposed progress, and the other is a white bar that almost seems like it's highlighting an "important" or "highly-viewed" part of the video, and the progress starts at the beginning of that section.

    Ultimately, I'm led to believe that Google is doing this on purpose, and maybe not particularly intending to say you've watched it already- but instead thinking you'll want to start watching at a particular timestamp and forcing the search result to start at that time. If I hover over the result itself, it even has t=355 in the URL, indicating the exact time it wants to start the video at.

    I disabled my "video resume" extension, and reloaded the page, and it does not appear that my extension thought I had watched this video already- even without the extension YouTube still has that result marked with the partial progress bar and timestamped URL, despite me never hovering or seeing this video until today, at all.

    So, this is not a fake progress bar or anything- Youtube is specifically altering a result to make it start at a particular timestamp. Unless this is something creators can do themselves, but it seems odd a creator would want you to skip parts of their video intentionally.
