When I search for something on Google and then go to
Videos tab, I get a URL like
(url for searching
tester in Incognito mode without active extensions)
sca_esv? ClearURLs extension does not block it.
From what I can tell, the number stays the same cross-search—even when I am in incognito mode.
- Mine is
- Removing the query parameter does not seem to affect the results of search
- Not UNIX time. The time is constant as well as being Friday, January 22, 1988
- Does not appear to be tied to IP. When I change location in VPN, I still get
- When Googling "sca_esv" the first result is a HN article with
sca esv=560664892perhaps there is some A/B testing Google is doing with
- Googling on my iPhone, I get

sca_esv=569877865what???? how does it know... circuit is even in a different country (Netherlands while I am in Chicago)
- I had my friend search
histring and they got a different
sca_esv. When they search
testerthey got the same
sca_esvas me when I search
tester(569877865). It looks like it is related to the query possibly. It is sticky: searching
hiwill have the same
tester(569877865). It appears to be sticky even across many different browsing sessions on Firefox for my friend.
sca_esvhas priority over
sca_esv. Once my friend searched for
tester, they were stuck with it and could not get back to
Is it some type of tracking ID perhaps?
Asking ChatGPT to brainstorm what
esv could stand for in the context of a Google search:
sca_esvparameter is a piece of data in the URL that's likely internal to Google's system for tracking, sorting, or customizing search results. URL parameters like these are often used for various purposes including analytics, session identification, and to tweak the behavior of the search. As for brainstorming what
sca_esvmight stand for, here are some speculative guesses:
- Search Context Algorithm - Elapsed Seconds Value: This could indicate that the search query has some kind of time-based context.
- Sorted Content Algorithm - Effective Sort Value: This might represent some value that helps in sorting the content in a particular way that Google's algorithms find effective.
- Session Customization Attribute - Event Specific Value: Perhaps this is a value that gets updated based on certain events or conditions met during your session.
- Systematic Categorization Algorithm - Engine Specific Variable: This could be a parameter specifically meant for Google's video search engine, categorizing the search in a systematic way.
- Search Customization And - Epoch Start Value: This could represent the start time for the search session in a specific time format, such as Mac Absolute Time as you mentioned.
- Server Client Agreement - Expiry Stamp Value: This might be a value indicating some sort of expiration or a time-sensitive attribute that gets reset.
