How to check GPTBot visits

Updated July 17, 2026

Use raw access logs first. GPTBot checks are easy to misread when OAI-SearchBot and ChatGPT-User are mixed into one dashboard line.

Quick process

1. Export recent access log lines with user-agent fields.
2. Filter for GPTBot only (case-insensitive).
3. Separate GPTBot from OAI-SearchBot and ChatGPT-User traffic.
4. Review status mix and path distribution before changing policy.

Nginx checks

grep -i "GPTBot" /var/log/nginx/access.log | tail -n 60
grep -i "GPTBot" /var/log/nginx/access.log | awk '{print $9}' | sort | uniq -c | sort -nr
grep -i "GPTBot" /var/log/nginx/access.log | awk '{print $7}' | sort | uniq -c | sort -nr | head -n 20

Caddy JSON checks

jq -r 'select(((.request.headers."User-Agent"[0]) // "") | test("GPTBot"; "i")) | "\(.status)\t\(.request.uri)"' /var/lib/caddy/logs/llmsfile-access.log | head -n 80
jq -r 'select(((.request.headers."User-Agent"[0]) // "") | test("GPTBot"; "i")) | .status' /var/lib/caddy/logs/llmsfile-access.log | sort | uniq -c | sort -nr

Useful distinction

• GPTBot: usually treated as training-policy crawler bucket.
• OAI-SearchBot: usually tied to search-style discovery.
• ChatGPT-User: user-triggered retrieval behavior.

What healthy GPTBot evidence looks like

1. You can see stable hits across multiple days, not a single burst.
2. Status mix is mostly 200/304 (unless intentionally blocked).
3. Paths include crawl-entry files and selected public content.

What to report to a stakeholder

Do not report "ChatGPT traffic" from a raw GPTBot count. Report GPTBot separately from OAI-SearchBot and ChatGPT-User, then explain what each line means.

Weekly rollup command

Use a weekly rollup to avoid overreacting to one quiet day.

# Nginx common log style
grep -i "GPTBot" /var/log/nginx/access.log* \
  | awk '{print $4, $7, $9}' \
  | sed 's/\\[//' \
  | cut -d: -f1 \
  | sort | uniq -c

# Caddy JSON logs
jq -r 'select(((.request.headers."User-Agent"[0]) // "") | test("GPTBot"; "i")) |
  (.ts | strftime("%Y-%m-%d")) + "\t" + (.status|tostring) + "\t" + .request.uri' \
  /var/lib/caddy/logs/llmsfile-access.log | sort | uniq -c

Common misreads

• Counting all OpenAI tokens as GPTBot.
• Interpreting one-day zero hits as permanent policy failure.
• Changing robots rules while Cloudflare edge rules are the real blocker.
