Short answer: On October 2, Google analyst Gary Illyes shared internal timings: a new URL is typically discovered in about 20 hours and indexed in about 1.5 hours. But the slowest case is "never," usually because of quality judgments, and AI Mode runs on the same index.
On October 2, 2026, Google's Search Central Live Deep Dive Europe in Barcelona reached its third day. Google analyst Gary Illyes walked through typical and slowest times for every step from "discovering a URL" to "a change taking effect": about 20 hours to discover a new URL, about 30 days to refresh a known one, 1–3 months for a site move and 3–6 months to recover from a core update. Attendee John Campbell's live recap shows the same word recurring in the "slowest" column: never. After PPC Land wrote it up on October 3, the table spread quickly through the SEO community.
Why now? AI search has turned "is my page indexed?" back into the most basic question. On day one, Illyes said AI Mode queries have doubled every quarter since launch, the average AI Mode query is about 3x the length of a traditional one, and 1 in 6 uses voice or images. Longer queries mean Google uses "query fan-out," issuing several related searches before composing an answer. And Google's own documentation is explicit: there are no additional technical requirements to appear in AI Overviews or AI Mode; a page only needs to be indexed and eligible to show with a snippet. Illyes closed with one line: "AI on Google is just SEO."
Other entry points work differently. Bing takes a push approach through the IndexNow protocol, letting sites notify Bing, Naver and Yandex the moment content changes. Google still mostly crawls on its own, and a sitemap is only a hint. ChatGPT and Perplexity run their own crawlers. The category is splitting into two paths: Google filters with a quality threshold, while other engines speed up through publisher pushes. The same article can appear in Bing within hours yet sit in Google's "Discovered – currently not indexed" bucket for weeks.
Does this affect SMBs? Yes, at the very front of the funnel. If new product, campaign or case-study pages are not indexed, neither Google Search nor AI Mode will cite you. Below: how to read the timing table, what three types of readers should do, which tools are worth using and a no-subscription indexing check.
Event details and numbers
Bottom line: discovery and indexing are measured in hours, refreshes and recoveries in months, and the slow part is quality, not technology (based on attendee notes; Google has not published a formal document).
| Stage | Typical | Slowest |
|---|---|---|
| New URL discovery | ~20 hours | Weeks to never |
| Known URL refresh | ~30 days | Weeks to never |
| Sitemap processing | ~24 hours | Up to 14 days, or never (quality) |
| Indexing (end to end) | ~1.5 hours | Months or never |
| Site move | 1–3 months | 6 months to 1 year+ |
| Core update recovery | 3–6 months | 6 months to 1 year |
- Who benefits: sites with solid content, clear internal links and stable servers; their new pages can be cited in AI Mode within a day.
- Who loses: sites with mass template pages, thin content and soft 404s (a 200 status with no real content). Illyes named DNS/CDN errors and soft 404s as the most common crawling problems.
What three types of readers should do now
Bottom line: owners should audit which key pages are missing from the index, marketers should stop resubmitting, and developers should fix sitemaps and soft 404s.
- Brand owners / SMB leaders: have someone open Search Console's Pages indexing report and list product and service pages under "Discovered" or "Crawled – currently not indexed."
- Marketing / SEO operators: stop clicking "Request indexing" on the same URL. Google's documentation says the feature has a quota, repeated requests will not speed things up, and recrawling can take days to weeks.
- Developers / agencies: make sure sitemap lastmod changes only when content actually changes. Google's sitemap guide says it ignores priority and changefreq, and a single sitemap is capped at 50,000 URLs or 50MB.
Indexing monitoring tools compared
Bottom line: Search Console and Bing Webmaster Tools are free and essential; paid tools pay off once you have thousands of pages.
| Tool | Main function | Cost | Best for |
|---|---|---|---|
| Google Search Console | Indexing report, URL Inspection, sitemap status | Free | Every site's first step |
| Bing Webmaster Tools + IndexNow | Push updates, AI Performance report (public preview) | Free | Getting new pages into Bing faster |
| Screaming Frog SEO Spider | Site crawl, soft 404 detection, sitemap comparison | Free up to 500 URLs; US$279/year paid | Health checks for sites with hundreds of pages or more |
| Ahrefs / Semrush Site Audit | Scheduled audits, indexing issue tracking | Monthly subscription | Teams already paying for either suite |
What nobody tells you
Bottom line: this timing table is not a service guarantee, and fast indexing does not mean AI will cite you.
- Counterpoint 1: the numbers have no methodology. Google calls them internal analysis but disclosed no sample, period or definition of "typical." Promising clients "indexed within 20 hours" means vouching for a number Google never committed to.
- Counterpoint 2: indexing is just the entry ticket. Being indexed does not mean ranking or being selected. AI Mode still runs fan-out, retrieval and selection, and most AI visibility tools only measure the last step.
A no-subscription alternative for SMBs
Bottom line: an accurate sitemap, an IndexNow ping on publish and a server-side log table let you measure your own indexing speed.
- Step 1: generate the sitemap automatically with a Laravel package such as spatie/laravel-sitemap, updating lastmod only when content changes.
- Step 2: queue a job that sends an IndexNow notification whenever an article is published.
- Step 3: log the first time Googlebot fetches each new URL to calculate your own "discovery time" and compare it with 20 hours.
- Step 4: export the indexing report monthly; merge, rewrite or remove pages that stay unindexed for 3 consecutive months.
FAQ
How long does Google take to index a new page?
Typically about 20 hours to discover and 1.5 hours to index. Low-quality pages can take weeks or never get indexed.
Does repeatedly clicking "Request indexing" help?
No. Google says the feature has a quota and repeat requests for one URL won't speed it up; internal links help more.
Do I need special optimization to appear in AI Mode?
No extra technical requirements. A page that is indexed and eligible for a snippet can be cited in AI Overviews and AI Mode.
Will IndexNow get Google to index me faster?
Not currently. IndexNow's official site lists Bing, Naver, Yandex and others as participants, not Google.
My take
My view: for most SMB sites, the bottleneck is too many thin pages, which runs against the mainstream reading that "indexing is fast, so GEO should focus on content format." The most important thing in this table is not 20 hours but the recurring "never." Many companies publish 100 generic posts a year and half of them sit in "not indexed." I expect that over the next 12 months, publishing less, merging and pruning will raise AI Mode citations more than publishing more.
Second: "AI on Google is just SEO" sounds reassuring but is really a warning. Google will not open a shortcut for AI search, so paying for "AI visibility acceleration" has limited value.
For ScriptWalker (a Taiwan-based Laravel/Flutter custom development studio), the opportunity is to package "sitemap cleanup + IndexNow push + Googlebot fetch-time logging + quarterly indexing health check" as a one-time setup plus quarterly maintenance service. Clients get no ranking promise, but they get an indexing speed report and a list of pages to merge or remove.
