Is IndexNow Worth It? 52 Days, 215 Pings, 15 Visits
I published an IndexNow key for this site on July 21, 2026, the same day the click tracker went live, and every post since has been pushed to the API with one curl at the end of the publish script. That is 52 days and, by the publish log, 215 submissions. The setup is in the IndexNow post I wrote on day four. What that post could not answer was the question people actually type into a search box: is IndexNow worth it. Seven weeks later I have a number, and it is smaller and stranger than the setup guides suggest.
The number is 15. Of the 123 human visits my referrer counter has logged from a search engine or an AI assistant, 15 came from an engine that reads IndexNow, 20 more from engines that resell Bing's index, and 55 from Google, which does not read IndexNow at all.
What IndexNow can reach, engine by engine
The protocol's own FAQ lists the endpoints that accept a submission: the shared api.indexnow.org, plus Amazon, Bing, Naver, Seznam.cz, Yandex and Yep. It says a URL sent to any one of them "will be shared across all IndexNow-enabled search engines". Google is not on the list; it said it was testing the protocol in November 2021 and nothing followed. So the first job with a referrer log is to sort each hostname by whether a ping could have had anything to do with the visit.
| Referrer host | Index behind it | Can a ping reach it? | Source |
|---|---|---|---|
| www.google.com | Google's own | No | Not on the participant list |
| bing.com, www.bing.com, cn.bing.com | Bing | Yes, participant | IndexNow FAQ |
| yandex.ru | Yandex | Yes, participant | IndexNow FAQ |
| duckduckgo.com | Links "which we largely source from Bing" | Indirectly | DuckDuckGo help |
| search.yahoo.com | Bing, since the 2010 transition | Indirectly | Search Engine Land |
| www.ecosia.org | Bing for all users, Google in some regions | Probably | Ecosia help |
| kagi.com | Own indexes plus "all major search result providers", unnamed | Unknown | Kagi docs |
| chatgpt.com, www.perplexity.ai | Each assistant's own retrieval, undisclosed | Unknown | Covered in the chatgpt.com referrer post |
| bsky.app | Not a search engine | No |
The count, 44 days of it
The counter is one Cloudflare Workers KV key per day per hostname, incremented only for user agents that pass the bot filter; the mechanics are in the click tracker post and the filter's gaps in the bot traffic post. It went live July 30, the first real referrer landed August 1, and the window runs to September 11: 44 days, 1,132 human pageviews. A small site's log, not a study.

Fifteen is a floor, for three reasons. A referrer arrives only when the engine sends one, so an engine that strips the header is invisible here. The counter sees humans, not crawls, and Bing has had a sitemap to read from day one, so even the 13 Bing visits do not prove a ping did anything the sitemap would not have. And there is no control group: I pinged every URL, so there is no batch of unpinged posts to compare against. The day-four post admitted it would have that flaw, and it does.
What moved in the week since the last count
The Day 9 post on September 4 drew the weekly curve: Google peaked at 24 visits in the second week of August and then fell to one or two a week while every other source rose. The seven days since have been the best week the IndexNow side has had. Of the 35 referrals logged between September 5 and 11, Bing sent 7, its highest weekly count, DuckDuckGo 7, Yandex 2, Ecosia 1, and Google 4.
| Week (Mon start) | Participants (Bing, Yandex) | Bing resold (DDG, Yahoo, Ecosia) | AI assistants | Kagi, other | |
|---|---|---|---|---|---|
| Jul 27 (from Aug 1) | 3 | 0 | 0 | 0 | 0 |
| Aug 3 | 17 | 0 | 0 | 0 | 0 |
| Aug 10 | 24 | 1 | 1 | 1 | 1 |

Yandex is the row I did not expect. It co-founded the protocol, I have never sent anything to its own endpoint, and it first appeared on September 6, 47 days after the first ping to the shared endpoint; Bing had taken 23. Yandex arriving unaddressed is what the FAQ's sharing clause looks like from the receiving end. Yahoo on September 7, Ecosia on September 10 and every DuckDuckGo visit since August 11 are a different mechanism: Bing's index reaching me through resellers. Count only hosts that consume the protocol and IndexNow has produced 15 visits here. Count the index the pings land in and it is 35.
What it cost
One text file at the site root and one HTTP request per post. The publish step deploys, waits for the new page to return 200, and only then fires the ping, so a submission never points at a page that is not live. The API's documentation assigns two success codes: 200 is "URL submitted successfully" and 202 is "URL received. IndexNow key validation pending". The first batch on July 21 came back 202. By July 30 the log shows 200, and all 215 responses logged since have been 200. No 403 for a bad key, no 422 for a foreign host, no 429 for spam, in seven weeks of one ping per post.

# 202 on July 21, 200 from July 30 onward, 215 timesWhat Bing says it is worth, and one report that says otherwise
Bing publishes the protocol's numbers as a share of Bing: 7% of all new URLs clicked in August 2022, then "over 3.5 billion URLs submitted per day" and "18% of all new URLs clicked in web search results" in its December 2024 post. A May 2025 post said "Amazon plans to begin adopting IndexNow in mid-June", which is why an Amazon endpoint now sits on the FAQ. None of that describes any one site's share of anything, and the FAQ says so: "each engine makes its own decision about whether to index it".
The pages that rank for this query mostly conclude there is no downside. One documented account disagrees about what it experienced. John Dalesandro writes that he enabled IndexNow through Cloudflare in March 2025, that "within a couple of weeks, the website completely disappeared from Bing search results", that an April support ticket got its first reply in August, and that as of January 2026 "Bing Webmaster Tools still reports that the website is indexed" while the site appears in neither Bing nor DuckDuckGo. He does not know whether IndexNow caused it, and neither do I. I include it because "no downside" is a claim about every site, and one site's log turns it into a claim that needs the word "usually".
One more confusion: a June 2024 Ask HN on IndexNow described DuckDuckGo as "about to make its mind" on joining. It never needed to; its results are largely Bing's, which is exactly why my count is 15 one way and 35 the other. Anyone quoting a number for IndexNow should say which one they mean.
So, worth it?
For this site, on this evidence: yes at the price, no as a plan. Fifteen certain visits and 35 plausible ones, out of 123 search-referred humans, for a key file and one line in a script. Google sent 55 without a single ping, and its curve is falling for reasons I cannot see, because Search Console was never verified here and the counter has no impressions. If you get to do exactly one thing before a new site's first post, verify Search Console. IndexNow is what you do in the twenty minutes after that. I will keep sending the pings and keeping the count, because the week Bing's index out-refers Google in this log is one I want a timestamp for. This week it did, 17 to 4.

FAQ
Does IndexNow work with Google?
No. Google is not on IndexNow's participant list, which names Amazon, Bing, Naver, Seznam.cz, Yandex and Yep alongside the shared endpoint. Google announced a test of the protocol in November 2021 and has not adopted it. To notify Google of a new URL you still use a sitemap or Search Console's URL Inspection tool.
Does IndexNow help DuckDuckGo find my pages?
Indirectly. DuckDuckGo does not accept IndexNow submissions itself, but its help page says its traditional link results are largely sourced from Bing, which does. On this site every DuckDuckGo visit, 18 in 44 days, came after Bing began sending visitors, which is consistent with that dependency without proving it.
What does a 202 response from the IndexNow API mean?
The documentation defines 202 Accepted as "URL received. IndexNow key validation pending" and 200 OK as "URL submitted successfully". A brand-new key returns 202 until the engine has fetched and verified the key file at your site root; this site's first submission on July 21, 2026 returned 202 and every submission from July 30 onward has returned 200. Neither code says the URL was crawled or indexed.

Method and sources: referral and pageview counts were read from this site's tracker stats endpoint on September 11, 2026 at 15:10 KST, ref: and hviews: prefixes; the referrer counter stores one hostname per day, excludes bot-pattern user agents, and cannot see stripped referrers. Weeks start on Monday. The 215 is the number of publish-log entries recording a 200 from the API; the July 21 202 is from my own July 24 post. Engine sources are quoted from the IndexNow FAQ and documentation, DuckDuckGo's results-sources page, Ecosia's providers article (updated August 12, 2026), Kagi's search-sources page and Search Engine Land's 2010 report, all read today. Bing's percentages are Bing's own figures. Neither Search Console nor Bing Webmaster Tools is set up for this domain, so crawl and index status are unknown on both sides.
