​I tracked 800 Reddit URLs on Google. 56% died within 48 hours.

​Everyone in the SEO space right now is obsessed with "Parasite SEO"-ranking Reddit or Quora threads on Google since the recent algorithm updates heavily favor UGC.

​I was doing it too, but I noticed a frustrating pattern: my traffic would spike, and then completely vanish a few days later. Standard rank trackers (which update every 3-7 days) were too slow to catch it. I was flying blind.

​To see if this was systemic or just my niche, I built a custom tracker and monitored 800 unique commercial UGC URLs on Google over 30 days.

​The Data:
The churn rate is absolutely brutal. Out of the threads that eventually dropped off Page 1, 56.1% of them were rotated out by Google within 48 hours. Only a tiny fraction survived longer than two weeks.

​It turns out Google is constantly rotating these UGC spots to test engagement. If you are building tier 2 backlinks to a Reddit thread, there is a massive risk you are pointing links to a URL that is already dead in the SERPs.

​The Free Data Dump:
I decided to open-source the data. I dumped the raw CSV of all 800 URLs on my site. If you want to run them through Ahrefs/Semrush to see if the surviving URLs had specific backlink patterns, you can grab the data here:

​(I also embedded a free little live-checker on that page. You can paste any live Reddit/Quora URL and it instantly checks the Serper API to see if Google has dropped it yet).

​Has anyone else noticed this insane 48-hour "half-life" for Reddit rankings, or are your threads actually staying stable? Curious to hear how other founders are navigating SEO right now.
