Mueller 2018 (reaffirmed May 2021): "we don't really have this traditional sandbox… these are essentially just algorithms trying to understand how this website fits in"
Summary
Claim: John Mueller (Google), 2018, reaffirmed May 2021:
"We don't really have this traditional sandbox… these are essentially just algorithms trying to understand how this website fits in."
Mueller explicitly refutes both a deliberate "sandbox" and a deliberate "honeymoon" (see also Mueller (May 2021) explicitly REJECTS both "sandbox" and "honeymoon" framings — "not the case that we're explicitly trying to promote new content or demote new content. It's just, we don't know and we have to make assumptions" for the lifecycle-brief canonical entry). The observable reality: new domains lack trust signals (backlinks, user-behavior history, established crawl patterns) so they compete at a disadvantage while Google accumulates data — the signals-vacuum reframing (Mueller (May 28, 2021 SEO office hours) on new-site ranking instability — "we don't have a lot of signals for that new content yet… we have to make assumptions").
Mueller has separately said the difference between a six-month-old and one-year-old domain "is really not that big," and that domain age has little to no direct ranking impact (see Domain age is NOT a ranking factor — Mueller: "No, domain age helps nothing"; asked who pushes the idea: "Primarily those who want to sell you aged domains :-)").

Confidence: Verified.
Caveat: The 2018 statement is older than the May 2021 office-hours framing the lifecycle brief leans on; cite the 2021 framing for the most current language. Cross-link: Google has denied the "sandbox" for ~20 years — Matt Cutts (2005), Gary Illyes (2016), John Mueller (August 19, 2019 tweet: "There is no sandbox"), hostAge leak attribute — documented as being used "to sandbox fresh spam in serving time"; this is a SPAM-CONTAINMENT filter that new low-trust sites can trip, NOT a blanket probation on all new sites (the one narrow point on which the 2024 leak partially vindicated skeptics).
