Google Sandbox After 30 Days — New Domain Search Recovery Patterns (GSC · Naver · Cloudflare Data)
Let me give you the conclusion first: the Google sandbox is real. On a new domain, indexing itself proceeds gradually (it started picking up around 5/22), but search impressions follow a spike-then-dip pattern almost exactly — peaking on 5/14 and dropping to near zero by 5/24. Honestly, if I hadn't had the Naver and Cloudflare data to lean on, I think I would have panicked. In my experience it should lift on its own within about 6–12 weeks.
Background
On May 9 I moved my domain from taystudio.github.io to taystudios.com (2026-05-09 migration). As far as Google is concerned, that effectively means a brand-new domain. So for the 30 days after that, I tracked the data across GSC, Naver, and Cloudflare myself and wrote down what was actually happening.
What Google Sandbox is
The Google sandbox refers to an unofficial algorithm that holds a fresh domain in a "probation" state for a while. The way I understand it, it has roughly this character:
- For 6–12 weeks the site gets indexed, but ranking gains are throttled
- The point is largely to filter out spam and MFA (Made For AdSense) sites
- In effect it's an evaluation period — "will this site still be alive in 6 weeks?"
- Google officially denies it, but it's something the SEO community observes pretty widely
30-day data
GSC (Google Search Console)
| Date | Clicks | Impressions | Avg position | CTR |
|---|---|---|---|---|
| 5/9 (migration) | 0 | 0 | — | — |
| 5/14 | 1 | 450 (peak) | 14 | 0.2% |
| 5/17 | 0 | 300 | 13 | 0% |
| 5/20 | 1 | 280 | 12 | 0.4% |
| 5/24 | 0 | 10 | 18 | 0% |
| 5/28 | 0 | 5 | 22 | 0% |
| 6/2 | 0 | ~0 | — | — |
It peaked on 5/14, dipped by 5/24, and then sat near zero. From the operator's seat, watching that graph, you can't help but wonder whether the site just died.
Bing Webmaster
Bing showed a similar pattern. There was residual data from the old domain through 5/12, and from 5/22 the sitemap was discovered with 124 URLs. Search impressions stayed at zero, though — Bing seems to put new domains in its own evaluation queue and make them wait too.
Naver SearchAdvisor (registered 5/22)
This is where it flipped. The spike started right after I registered on 5/22, peaked on 5/27 at 7,600 impressions, and after 5/28 settled into a stable 2,000–3,000 per day. Over the 30 days the totals came to 26,000 impressions and 230 clicks.
That works out to roughly 33–115× Google over the same period. The content is aimed at Korean users to begin with, so Naver's matching just fit it much better.
Cloudflare Web Analytics
I used Cloudflare to see total traffic across all channels. Visits averaged around 55 a day, and 79% of that was Naver/Daum referrers. Some chatgpt.com referrers started showing up too (which I read as AI-search exposure beginning), but more than anything, the site itself was running perfectly fine.
Finding 1 — Google sandbox only throttles rankings
The first thing I confirmed from the data was that indexing itself was proceeding fine. On 5/22, 122 pages were indexed; on 5/29 only 7 pages were "not indexed," and those broke down as 4 redirects, 1 canonical, and 2 queued — all perfectly normal reasons. By 6/2 all 124 sitemap URLs had been discovered.
In other words, Google was finding, crawling, and indexing the site normally. What's throttled is purely position on the SERP, and on the same keywords the older domains kept winning out.
Finding 2 — What the 5/14 spike was
The sudden jump to 450 impressions on 5/14 looks to me like Google running a kind of test exposure on the new domain — checking whether the site is real and how users respond to it (CTR, dwell time).
The 5/17–24 dip that followed amounts to the verdict: "for now, keep it in the sandbox." The CTR was around 0.3%, and I suspect that fell short of the bar needed to release a fresh domain.
Finding 3 — Naver has no equivalent of sandbox
With Naver, indexing and impressions started the moment I registered on 5/22. It hit 2,000+ daily impressions within 3 days, so there's effectively no probationary period to speak of. Naver processes things quickly once a sitemap is submitted, and it doesn't seem to hand out much of a penalty just for a domain being new.
Finding 4 — AI search is becoming a new channel
A chatgpt.com referrer started appearing in Cloudflare. I read that as LLMs — ChatGPT, Claude, Perplexity — beginning to learn from the site or cite it in their answers. What's interesting is that this is a completely separate channel, independent of the Google sandbox.
Estimated — when Google sandbox lifts
| Domain age | Sandbox status | Search impressions |
|---|---|---|
| Week 1 (5/16) | Initial evaluation | Spike starts |
| Week 2 (5/22) | Evaluation continues | Spike peaks |
| Week 3 (5/29) | Dip | Near zero |
| Week 6 (6/20) | Partial recovery expected | Gradual rise |
| Week 12 (7/30) | Full recovery expected | Normal impressions |
This timeline is an estimate based on general SEO experience, not anything Google has stated officially. Content quality, E-E-A-T, and backlinks can all shorten it.
Actions during sandbox
The sandbox is a waiting period either way, so I spent the time shoring up the site itself.
Content reinforcement
- Fixed stale numbers across 18 tools (24 wrong numbers)
- Added 5 differentiating matrices (inheritance break-even, loan DSR, 6+6 parental leave, and so on)
- Rewrote the title/description on the Top-5 pages with CTR in mind
- Started a blog post series
Diversify search channels
- Registered on Naver SearchAdvisor and submitted sitemaps
- Submitted URLs directly via Bing Webmaster (10)
- Daum Webmaster is still on the to-do list
- Updated llms.txt and added an explicit Allow for LLM crawlers in robots.txt, to spread into AI-search as well
Status (month 1)
- Google: sandbox (waiting)
- Naver: ~50 visits/day, steady
- Bing: sitemap discovered, crawl pending
- AI search: some referrers showing up
Operator takeaways
1. Set the right expectation before migrating
Once you move to a new domain, it's fair to assume search impressions will be near zero for 0–3 months. If your business depends on search traffic, you really want to think hard before migrating.
2. Don't read GSC alone
Don't panic over a single dataset. If I'd only looked at GSC, my nerves would have been shot — but because I read Naver, Cloudflare, and Bing together, the whole picture came into view.
3. Differentiated content is sandbox-independent
Matrices, simulations, visualizations — that kind of differentiated content accumulates as long-tail SEO regardless of the sandbox. It builds up quietly and then pays off the moment the sandbox lifts.
4. AI-search exposure is a separate channel
ChatGPT, Claude, and Perplexity starting to cite the site is an early sign of future traffic. It's worth leaning into llms.txt now.
One-liner
The Google sandbox is real. But for a Korean site, Naver carries you through it. Don't panic — ride it out with time, content, and a mix of channels.
I'll write a follow-up around late July or early August to confirm whether the sandbox actually ends, using the real numbers from that point.
