How long does Baidu take to index a site? No official number

The short answer

Nobody can give you a reliable number. For most sites, Baidu says only that indexing runs on a cycle, and it publishes no ranking timeline. Agency and blog estimates for indexing run from 1 day to 3 months, with no method shown. Plan by stage instead: check whether Baidu has found, crawled, indexed and then shown your pages.

Baidu's February 2021 Q&A says indexing runs on a cycle, and gives no length for it.
Baidu's platform guide says fast crawl usually indexes within 48 hours, only for selected sites and mobile or adaptive pages.
Published estimates we read for new-site indexing run from 1 to 7 days up to 1 to 3 months, none with a method.
One foreign site took about 18 months to reach full-text matching, on December 28, 2018.
Baidu says its index data from October 14 to 23, 2026 has no reference value.

Perplexity

If you’ve just launched a site, you want a date. Any date you’re given for Baidu is a guess, including the confident ones.

What you can do is split the wait into stages, and see which one you’re in. This guide is part of our work on Baidu SEO.

Does Baidu publish a timeline?

Not a general one. Baidu’s Q&A says only that indexing “runs on a certain cycle”, and that valuable content is crawled and indexed within it.¹ It never says how long the cycle lasts.

The same Q&A says next-day indexing is limited to a very small share of high-quality, highly timely content.¹ We found no Baidu text giving any timeline for ranking.

Why one number can’t answer the question

“Indexed” and “ranking” are different events, and four separate things must happen. A figure for one tells you nothing about the next.

Baidu describes crawling, index building and ranking as distinct steps, and adds that the number of pages crawled matters less than the number built into the index.²³

Fig. 1The four stages

Discovered
Baidu learns the URL exists.
Crawled
Baiduspider fetches it.
Indexed
It enters a layer of the index.
Ranked
It appears for a real search.

Stage	What decides it	What Baidu says about time
Discovered	Links, or your submission ²⁵	Submitting shortens discovery ⁵
Crawled	A daily crawl quota per site ³	Nothing general
Indexed	Value of the content ¹	“A certain cycle” ¹
Ranked	Relevance, authority, freshness, quality ²	Nothing

Being indexed isn’t one state either. Baidu says its index has layers, and pages in the lower layers have little chance of being seen.⁶ So a page can be “in Baidu” and still be nearly invisible.

What published estimates say

Published estimates for indexing disagree widely, and none shows how it was measured. Here are the figures we could open and read, with their dates and sellers.

Source	Claim	Basis given
Weikubao on Sohu, February 2026	1 to 7 days at best, for a well-built new site ¹⁹	“Data shows”, none named. Sells site building
Elite Asia, July 2026	About 1 week for new pages ¹⁶	None. Sells SEO
Jiemian reprint, February 2015	15 days on average, 1 to 2 months if slow ¹⁸	“Experience”
Naibabiji, December 2019	Observation period of 1 to 3 months ¹⁷	None. Blog author sells paid help
Chinafy, dated May 2022	About 1 to 3 months after submission ¹⁵	None. Sells China web services
Chinafy, November 2024	About a week ²⁷	None. Same vendor, a different figure
Marketing to China, September 2026	“Months” without Webmaster Tools, for new or rarely linked domains ²¹	None. Sells SEO

Ranking estimates are rarer. Marketing to China gives 3 to 6 months for meaningful rankings, with no source.²⁶ Elite Asia advises budgeting six to twelve months before significant visibility, for new sites in competitive spaces.¹⁶

Elite Asia shows no data. It also describes a 90-day re-evaluation cycle that we found nowhere in the Baidu pages we read.¹⁶

Is there a Baidu sandbox?

Maybe, but it’s a practitioners’ theory. We found no mention of a sandbox or observation period in the Baidu pages we read.

Naibabiji calls it an observation period of 1 to 3 months.¹⁷ The 2015 Jiemian reprint says Baidu lengthened its evaluation of new sites in 2014, and puts a sandbox exit at two to three months or more, citing nothing from Baidu.¹⁸

Batman IT says sandboxes still exist, based on years of practice, and that Baidu documents occasionally mention something similar.²⁰ We didn’t find one. He then adds that they have no fixed length, and that his article is for reference only.²⁰

Baidu’s own answer is plainer. Asked why a new site isn’t indexed, it says to check whether the content is good, valuable and not widely duplicated.¹ It doesn’t tell you to wait. So look there before you assume time will fix it.

What changes the wait

Baidu names several things that affect crawling and indexing, though it doesn’t say by how much.

Reachability. Connectivity is one of four factors in the crawl quota, with update frequency, update quality and site rating.³ Baidu’s text covers Chinese carriers, not cross-border routes.
Links. In 2017, Baidu called links the most important way to find pages.²⁵ A rarely linked site gives it fewer paths in.
Update frequency. “Update fast, come more often; update slowly, come less,” in Baidu’s 2014 words.³
Submission. The tool shortens discovery, but Baidu says it can’t settle whether content gets indexed.⁵ API push is faster than a sitemap.⁴
Content value. Baidu lists sites with duplicate content, thin main content or rule violations among those that may not be indexed at all.²

An account isn’t needed for Baidu to find a page. Its 2023 notice on at-risk sites says removing a site’s verification doesn’t affect natural discovery, display or ranking.¹⁰

You do lose the tools, including submission. See how to submit your site and how to set up Baidu Webmaster Tools.

Hosting abroad is a known unknown. Baidu warned in 2017 of display problems for Chinese sites on foreign servers, with no figures.¹¹

What one foreign site’s timeline looked like

We found only one dated public record, and it’s slow. Silas S. Brown kept a log for a personal site with English and Chinese pages, hosted at the University of Cambridge.²³

November 2017URLs posted on Baidu Knows, still not indexed a month later.
December 2017URLs pinged to Baidu, no listings by February 2018.

The durations Baidu does publish

Baidu gives precise numbers for nearby operations, and they’re more useful than the estimates above. Most are several years old, so check them inside your account.

Operation	Baidu’s stated time	Source date
Fast crawl tool, selected sites, mobile or adaptive pages	Usually indexed within 48 hours ⁴	2021, edited since
Index volume data updates	Daily at best, weekly at worst ⁶	2020
robots.txt change takes effect	About 48 hours ¹²	Undated
Blocked pages leave the index	Several months ¹²	Undated
Dead link removal	1 week after crawling ⁷	2021
Feedback Center first reply	3 working days ⁴	2021
Site redesign rule takes effect	12.5 to 50 hours ⁷	2021
Keep redirects after a redesign	At least 3 months ⁷	2021
Old content and domain gradually replaced	6 months or more of stable running ¹	2021
Fenghuo 3.0 penalty, second offense	3-month observation ¹⁴	2020

The 48-hour figure needs care. Baidu’s system chooses which quality sites get fast crawl, and it covers only mobile and adaptive pages.⁴ The tool replaced fast indexing in April 2024.⁹

We don’t know if a foreign site can get it. So don’t plan around that number.

Indexing isn’t permanent

Getting in doesn’t mean staying in. Baidu says it updates its index from time to time and may delete low-quality pages.¹ It adds that swings of 10% or more can be normal.⁷

Brown’s log shows how quickly it can move.²³

Day-long 403 errors, 2019: three outages, listing unaffected.
About 120 hours of 404 errors, June 2019: homepage dropped by June 24, back by June 28.
Server switched off, September 27, 2019: homepage dropped by September 29.
Redirect set up on a new server, October 8, 2019: homepage back the same day.

The owner reports the Chinese pages as de-listed since 2022, after repeated drops.²³ A contact later told him of an “overzealous” purge at Baidu, which he doesn’t confirm. So the cause is unknown, and it’s one site. Still, it’s a reason to keep your site up during any move.

How to tell which stage you’re at

Check the stages in order, because each one explains a different failure. There’s no official date at which to worry, so what matters is where things have stopped.

Discovered and crawled? Search your server logs for Baiduspider, and confirm the hosts by reverse DNS, as Baidu advises.¹² No visits points to reachability, links or submission.
Seen correctly? If you have an account, use the crawl diagnosis tool. It shows only the first 200 KB Baiduspider sees.⁷
Indexed? Use the index volume tool, which is the reference. The site: search is only an estimate.⁶¹³ Our guide to checking indexed pages has the method.
Showing for searches? Check the traffic and keywords tool,¹ or search your exact page title. Then see Baidu’s ranking factors.

If a stage stays stuck, see why your site isn’t showing on Baidu. If you can’t wait for organic results, compare Baidu SEO and Baidu Ads.

The bottom line

Nobody outside Baidu knows how long it will take for your site, and Baidu doesn’t say. The estimates in circulation differ widely and show no method.

So work by stage rather than by date: confirm crawling first, then indexing, then visibility. Treat anyone who promises a date with suspicion.

Common questions

Is Baidu slower than Google at indexing?

Vendors say so, but we found no published measurement. Elite Asia gives about one week for Baidu against hours for Google, without a source.¹⁶ SEO Sherpa says only that Baidu's crawler is less fast and frequent.²² Both may be right, but neither shows data. Avoid carrying a Google timeline over to Baidu.

How long does a new page take on a site that's already indexed?

Baidu gives no figure for this either. Its Q&A says next-day indexing reaches only a tiny share of timely, high-quality content.¹ SEO Sherpa says new content can rank faster once a site earns credibility, without numbers.²² Your own server logs will show the gap on your site better than any general estimate.

Does a new domain take longer than an old one?

It may, but we can't prove it. Baidu's crawl article names update frequency, update quality, connectivity and site rating, and domain age isn't on that list.³ We found no Baidu text on domain age in the pages we read. A site rating could favor older sites, but that's our inference, not Baidu's statement.

Would mainland hosting or an ICP speed up indexing?

Sources disagree, and we found no Baidu text saying so. Naibabiji said in 2019 that ICP-filed sites can apply for "new site protection" to index faster, a tool we couldn't find at Baidu.¹⁷ Baidu's 2017 notice warns of display problems on overseas servers.¹¹ In 2021, sites without an ICP had a lower sitemap quota, which may no longer hold.²⁴ See ranking without an ICP.

Can I pay someone to get indexed faster?

Be careful. Baidu says it can't guarantee indexing of submitted links, so no outside seller can promise it either.⁵ Inflated clicks and link schemes fall under Baidu's penalties.¹⁴ Paying for help with setup and submission is reasonable. Paying for a guaranteed index date isn't, and the same goes for ranking dates.
