Fact Check: Cookie duration: 1825 (days)

Fact Check: "Cookie duration: 1825 (days)"

What We Know

The claim that the cookie duration can be set to 1825 days (which is equivalent to 5 years) is misleading. Cookies are small files stored on a user's computer that help websites remember information about the user. The duration of cookies can vary significantly based on their purpose and the settings configured by the website owner.

According to What is Cookie Duration and How to Use it, the default duration for cookies in many affiliate marketing contexts is typically set to 30 days. This means that if a user visits a site through an affiliate link, the cookie will expire after 30 days unless a purchase is made within that timeframe.
The same source indicates that while it is possible to increase the cookie duration, there is no standard option to set a cookie duration to an extremely high value like 1825 days. Instead, it suggests that a very high number such as 32000 (approximately 100 years) can be used, but this is not a common practice.
Furthermore, Google’s support documentation on cookies emphasizes that cookies can influence how Google accounts interact with third-party applications, but it does not specify any duration as long as 1825 days (Cookie を有効または無効にする).

Analysis

The claim that cookie duration can be set to 1825 days lacks credible support from reliable sources. Most reputable sources, including those focused on cookie management and affiliate marketing, indicate that typical cookie durations range from 30 to 90 days, with some flexibility for longer durations, but not to the extent of 1825 days.

The source from What is Cookie Duration and How to Use it clearly states that while cookie durations can be extended, there is no standard practice for setting them to 1825 days, and it highlights that a duration of 30 days is the norm.
Additionally, the Google support documentation does not provide any evidence that cookies can last for such an extended period, further undermining the claim.

The lack of empirical evidence supporting the claim, combined with the consensus from multiple credible sources, suggests that the assertion is not grounded in standard cookie management practices.

Conclusion

Verdict: False. The claim that cookie duration can be set to 1825 days is misleading and unsupported by credible sources. The typical cookie duration is much shorter, usually around 30 days, with some flexibility for longer durations, but not to the extent of five years.
