How Long Google Actually Takes to Crawl, Index and Serve — Google’s Own Numbers
At the Google Search Central Live Deep Dive event in Europe, Gary Illyes showed internal data on how long each stage of search actually takes, broken out by process, with a typical figure and a slowest figure for each. Attendees described it as the highlight of the day, and it is the most useful thing published about search this quarter.
One caveat from Illyes, which he repeated afterwards: the exercise was to see whether an audience could relate to numbers pulled internally. So read these as indicative ranges, not as service levels.
They are still far more honest than anything in a typical SEO timeline.
Crawling
| Process | Typical | Slowest |
|---|---|---|
| Discovery (new URL) | ~20 hours | Weeks to never |
| Refresh (known URL) | ~30 days | Weeks to never |
| Sitemap processing | ~24 hours | Up to 14 days, or never (quality) |
| robots.txt update | ~24 hours | 25 hours |
| Crawl capacity update | 4 hours to 1–2 weeks | 1–3 weeks (in recovery) |
| Crawl demand update | ~20 hours | Weeks to months |
Two rows deserve attention. First, discovery of a new URL: twenty hours is the typical case, and “never” is on the slowest end of the same row. Second, refresh of a known URL at a typical thirty days. If you update a page and expect Google to see the new version within a week, you are on the fast side of a distribution that has a very long tail.
There is also a warning hidden in the crawl capacity row. Illyes noted that crawl capacity can drop in seconds when Google backs off — for instance if your server struggles — but the climb back takes one to three weeks. Asymmetric, and expensive.
Indexing
| Process | Typical | Slowest |
|---|---|---|
| Rendering | Seconds to render, hours in the queue | Days to weeks |
| Meta annotations | 45–90 minutes | 1–4 days |
| Link annotations | Minutes to 1–3 weeks | Months |
| Indexing (end to end) | ~1.5 hours | Months or never (quality) |
| Removal | 1–3 weeks | Months |
| Canonicalisation change | 1–3 weeks | Months (conflicting signals) |
| Site move | 1–3 months | 6 months to 1 year+ |
| Structured data updates | Hours to 1–2 weeks | Weeks or never (quality) |
The link annotation row is the one this blog cares about most. It is the stage where Google works out what a link means and how to weigh it, and the range runs from minutes to months.
What this changes about link building timelines
Most of the dispute over whether link building works is really a dispute about time. One side measures at four weeks and sees nothing; the other measures at six months and sees a shift. The table above explains why both are describing the same system: the typical case is one to three weeks, and the tail is measured in months, with quality as one of the gates.
Three practical consequences.
Stop diagnosing at week three. A placement submitted three weeks ago is inside the normal range for link annotation. Judging it then produces a conclusion about your patience, not about the link.
Build in batches, spaced. Because refresh of a known URL typically takes a month and crawl demand updates can take much longer, sudden spikes in off-site activity look different from steady additions. Spacing your submissions also means you can attribute movement to a period instead of guessing.
Keep your own record of the dates. The single most useful thing you can have when results are inconclusive is a list of what was placed, where, and when. That is also the practical reason the mechanical part of this is worth handing over: a service such as https://backlinksubmit.org matches your product to relevant directories from a handpicked list, submits manually, and shows you in a console which platforms have been submitted and how each is progressing — which is the difference between “we’re waiting on annotations” and “we forgot to submit.”
The slow rows that surprise people
Site moves take one to three months typically, and up to a year in the worst case. If you are planning a domain change, the timeline in your project plan is wrong.
Canonicalisation changes take one to three weeks, and months when signals conflict. This is why defensive canonical work is slow — you find out whether it worked a month later.
Removal is faster than indexing in the typical case and can still take months. Being unable to get something out quickly is a risk worth remembering before publishing at scale.
The honest conclusion
Search is a slow, lossy, quality-gated system with a long tail on every process. That has always been true; it is just usually described by vendors who benefit from implying otherwise.
The useful move is to plan in quarters, measure in months, and keep a dated record of what you did. The rest is impatience with a chart attached.
FAQ
Are these official Google service levels?
No. Illyes described the exercise as checking whether internal numbers resonated with an audience. Treat them as indicative ranges — the value is in the shape, not the exact figures.
How long before a new backlink counts?
Link annotations typically run from minutes to one to three weeks, with months at the slow end. Judging a placement before a month has passed is guesswork.
Why does recovery take longer than the problem?
Crawl capacity can drop in seconds but takes one to three weeks to climb back. That asymmetry appears throughout the data.
What’s the one thing worth doing differently?
Record the date of every placement. Without it, every later conversation about results is an argument about memory.
