Two days ago I published a census of every AI crawler that hit my site over 34 days. The headline was that ChatGPT now fetches my pages for live users more often than Googlebot crawls them. This post is about the number in that dataset I couldn't stop thinking about — the one that isn't ChatGPT at all.
It's bingbot.
Fresh numbers from this morning's run (36 days of Caddy access logs, HTTP 200 responses only, for a small business site):
| Bot | Hits | Per day |
|---|---|---|
| bingbot | ||
| 4,488 | ||
| 123.3 | ||
| ChatGPT-User (live retrieval) | 1,394 | 38.3 |
| Googlebot | 1,073 | 29.5 |
| GPTBot (training) | 505 | 13.9 |
| OAI-SearchBot | 249 | 6.8 |
Bing's crawler reads my site 4.2 times more than Google's. For years I would have read that as wasted crawl budget from the search engine nobody uses — Bing's share of human search traffic barely registers in my analytics.
Then you put the second fact next to it: Seer Interactive ran 500+ citations through SearchGPT and found that 87% of them matched Bing's top-10 organic results for the same query. Only 56% matched Google's top 10.
ChatGPT's web search doesn't have its own index. When it goes looking for sources to cite, it queries Bing. Those 4,488 bingbot hits aren't for Bing's ten human users — they're the supply chain for every ChatGPT answer that might mention you. Bing stopped being a search engine and became an API for AI answers, and its crawler's appetite finally makes sense.
The chain is visible end to end in my own data. bingbot's most-crawled pages this window are my blog's long-form posts and guides. And the pages ChatGPT-User actually fetches when a human asks something? The same category: my Chatwoot-vs-Intercom comparison got 101 live ChatGPT retrievals in 36 days, and a Hebrew post about WhatsApp spam law got 226 retrievals from Claude-User alone. Comparison pages and definitive guides go in through Bing, come out as citations.
I run a WhatsApp automation studio in Israel, and this pipeline stopped being theoretical for me in mid-July, when a Google core update cut my Israeli search clicks nearly in half. The traffic that kept arriving through the collapse was exactly this AI-assistant channel — which, per Seer's data, is largely downstream of an index I had never once logged into.
One more uncomfortable detail from the earlier post: when I compared server logs to Google Analytics, GA4 saw about 11% of the visitors the logs saw. AI-referred and privacy-shielded traffic is mostly invisible to your dashboard. If you only look at GA4, this entire channel doesn't exist.
If 87% of ChatGPT citations come from Bing's top 10, then "rank in Bing" is now a growth channel with almost no competition, because everyone else is still fighting over Google. What I've changed:
1. Stop treating bingbot as a nuisance. Plenty of robots.txt files and WAF rules throttle or block bingbot to "save crawl budget." That's now equivalent to blocking your ChatGPT visibility at the front door. Check yours before anything else.
2. Register in Bing Webmaster Tools. It takes minutes (you can import your verified site straight from Google Search Console) and it's the only place you'll see how Bing actually indexes you.
3. Ship IndexNow. Bing supports instant push indexing — a tiny API ping on every publish instead of waiting for a crawl. For a channel where citations follow the index, freshness is free ranking.
4. Feed it the content type the pipeline rewards. In my logs, what gets retrieved for live users is comparisons ("X vs Y"), pricing breakdowns, and complete guides — pages that answer a full question. Listicle fragments don't get cited.
5. Measure in your logs, not your analytics. Thirty seconds on any server:
grep -c 'bingbot' access.log
grep -c 'Googlebot' access.log
grep 'bingbot' access.log | awk '{print $7}' | sort | uniq -c | sort -rn | head
(Adjust the $7
field for your log format; mine is Caddy JSON piped through a small parser.)
I spent years doing SEO for an audience of humans on Google. The team behind 50+ WhatsApp bot deployments that pays my bills gets found today by a different reader: a retrieval bot working for an AI that a buyer asked in natural language. That reader enters through Bing, and almost nobody is holding the door.
Run the grep above on your own logs and tell me your bingbot-to-Googlebot ratio in the comments — I'm collecting data points for a follow-up post. Mine is 4.2:1. If yours is under 1:1, I'd especially like to know what kind of site it is.
