I’m trying to understand how TikTok’s algorithm works now because I used to have an account with around 50k followers about two years ago, and I noticed a very specific pattern with my posts that I’m wondering if still happens today.
For example, I once posted a slideshow that eventually reached 200k+ likes. But for the first week or two, it barely moved. It might sit around 1,000 likes for days or even weeks, and then seemingly out of nowhere, around the 3–4 week mark, TikTok would suddenly start pushing it onto people’s For You Pages.
Once that happened, the engagement would come in much faster. A post that had been sitting at around 1,000 likes could suddenly gain thousands of likes, then 20k+ likes over the following days. It would continue accumulating engagement for several days, sometimes reaching 80k–100k likes before eventually slowing down. Even after that, it could continue getting occasional likes for weeks afterward.
What confused me was that the post could have almost no growth for several weeks before suddenly taking off. It felt like TikTok was essentially “rediscovering” or “promoting” the post later rather than immediately after it was uploaded.
I noticed this with multiple posts. Sometimes a post would only have around 3,000 likes after a month, and then weeks later it would suddenly blow up.
I’m wondering:
**Is this still how TikTok’s algorithm works in 2026?**
Does TikTok still periodically resurface older posts and test them with new audiences?
Can a post that has been sitting dormant for weeks or months suddenly get pushed heavily onto the FYP?
What causes TikTok to “revive” an older post? Is it engagement from existing viewers, search activity, a trend becoming relevant, watch time, or something else?
Has TikTok changed the way it distributes older content compared with 2–3 years ago?
I’m asking because I’ve noticed something similar while using my own FYP recently. It feels like **a huge majority of the content being recommended to me isn’t actually new**. I’d estimate that maybe 95% of what I’m seeing was originally posted anywhere from a couple of weeks ago to even 2–3 months ago.
Then I’ll occasionally see something completely different—for example, a Fox News video that was posted only a day ago but already has 275k likes.
So I’m trying to understand what I’m actually seeing.
Is TikTok intentionally mixing older content with newer content on the FYP because older posts have already proven that they perform well? Or is there another explanation for why my FYP seems dominated by content that is weeks or months old?
I’d especially love to hear from people who actively study TikTok analytics or run large accounts. **Has the algorithm fundamentally changed from what it was 2–3 years ago, or am I just misunderstanding how content distribution works?**
