What is Klaviyo AI?

Klaviyo AI is an AI data-collection crawler operated by Klaviyo. It gathers public web content to build or refine training datasets for large language models. Like other AI training crawlers, Klaviyo AI does not influence your search-engine rankings, so you can block it via robots.txt without any SEO penalty if you wish to opt out of AI training.

Klaviyo AI is an AI data-collection crawler operated by Klaviyo. It gathers public web content to build or refine training datasets for large language models. Like other AI training crawlers, Klaviyo AI does not influence your search-engine rankings, so you can block it via robots.txt without any SEO penalty if you wish to opt out of AI training.
Klaviyo AI uses the user-agent token KlaviyoAIBot. You can control it via robots.txt, meta tags (noai), or the emerging llms.txt standard. Robots.txt is voluntary; for hard enforcement, combine it with server-level IP blocking.

What happens if you block Klaviyo AI?

✅ No SEO Impact - Blocking Klaviyo AI does not affect your rankings in Google, Bing, or any other search engine. Klaviyo AI is an AI crawler, not a traditional search indexer. You can freely block it via User-agent / Disallow: / without any SEO penalty.
Generally safe to allow; provides legitimate crawling value.

How to block Klaviyo AI with robots.txt

<code>User-agent: KlaviyoAIBot</code> - Matching is case-insensitive. Robots.txt is fetched from the root of each subdomain separately.

Block completely (robots.txt)
User-agent: KlaviyoAIBot Disallow: /
Allow all (robots.txt)
User-agent: KlaviyoAIBot Allow: /
Block private only (robots.txt)
User-agent: KlaviyoAIBot Disallow: /private/ Disallow: /api/ Disallow: /admin/ Allow: /
Nginx server block
# Nginx: Hard-block Klaviyo AI if ($http_user_agent ~* "KlaviyoAIBot") { return 403 "Bot blocked"; }
Apache .htaccess

Is Klaviyo AI safe to allow?

Yes, Klaviyo AI is a safe and legitimate crawler operated by Klaviyo. It follows the Robots Exclusion Protocol (RFC 9309) and can be controlled with standard robots.txt rules.
Verify by reverse-DNS lookup: legitimate Klaviyo AI requests resolve to Klaviyo's domain.

What does Klaviyo AI do?

Understanding Klaviyo AI's purpose helps you decide whether to allow or block it.

  • Collects public web content to train large language models
  • Builds and refreshes AI training datasets
  • Harvests text, code, and structured data for model improvement
  • Does NOT affect search-engine rankings
  • Can be blocked to opt out of AI training without SEO loss

Klaviyo AI in context

Klaviyo AI is a training crawler operated by Klaviyo. In plain terms, it collects pages to train AI models. Our database files it under AI and LLM crawlers and ranks it Tier 2, important crawlers from established AI and search operators. 74 of the 104 AI and LLM crawlers in our database share this tier.

Its safety rating is safe and its blocking impact is low. So the decision about Klaviyo AI rests on what you want from Klaviyo, not on its behaviour. How we rate safety and impact.

How site owners treat Klaviyo AI

Our robots.txt study of the Tranco top 10,000 did not track KlaviyoAIBot as a named token, so we do not publish an adoption figure for it. If you run a large site, your own logs are the best evidence of how often it visits.

Does it follow robots.txt?

Klaviyo AI's operator does not clearly document how it treats robots.txt. Write the Klaviyo AI rule anyway, then confirm in your logs that its requests stop.

Klaviyo crawlers and close alternatives

Klaviyo runs only this one crawler in our database, so a single User-agent: KlaviyoAIBot group controls everything Klaviyo fetches through it.

Other AI and LLM crawlers that do the same job (collects pages to train AI models) include ClaudeBot from Anthropic, Google-Extended from Google, GPTBot from OpenAI, Meta-ExternalAgent from Meta, AI2Bot from Allen Institute for AI, aiHitBot from aiHit. Deciding about Klaviyo AI is usually a decision about the whole group, so check how your file treats these too.

We first recorded KlaviyoAIBot on June 18, 2026. Klaviyo documents it on help.klaviyo.com, and we recheck that page before each release.

Which rule Klaviyo AI actually follows

Klaviyo AI reads exactly one group in robots.txt, the most specific one that names KlaviyoAIBot, and never combines rules across groups. This short file shows the trap:

User-agent: *
Disallow: /private/

User-agent: KlaviyoAIBot
Disallow: /drafts/
  1. Find the group. Klaviyo AI looks for a group naming KlaviyoAIBot. One exists, so it ignores User-agent: * completely.
  2. Apply only that group. It is refused /drafts/ and nothing else.
  3. The surprise. /private/ is open to Klaviyo AI, because that rule lives in the * group it no longer reads. To keep it out of both, repeat Disallow: /private/ inside its own group.
Test yourself: does a rule under User-agent: * apply to Klaviyo AI if the file also has a User-agent: KlaviyoAIBot group?

No. Once a group names it, Klaviyo AI reads only that group. Put every rule you want it to follow inside its own group.

Test yourself: will blocking Klaviyo AI remove your pages from AI answers?

No. Klaviyo AI collects training data. Blocking it changes what future models learn, not which pages AI answers cite today.

Test yourself: is User-agent: klaviyoaibot the same as User-agent: KlaviyoAIBot?

Yes. RFC 9309 makes user-agent matching case-insensitive. Paths are a different story: Disallow: /Blog/ does not block /blog/.

Should you allow Klaviyo AI? Decide by situation

Recommended setting for Klaviyo AI by type of site
If you are...Recommended setting
You publish content and want AI answers to cite itYour call. Klaviyo AI is a training crawler, so blocking it does not remove you from AI answers; retrieval crawlers do that job.
You license content and want to stop AI trainingBlock it by name with User-agent: KlaviyoAIBot and Disallow: /.
You run an online shopAllow it unless your logs show it is costly.
Your server is under load from botsRate-limit before blocking. It is rated safe in our database.

Check Klaviyo AI on your own site

  1. Open /robots.txt on your domain and search for KlaviyoAIBot. If it is not named, it follows User-agent: *.
  2. List the Disallow lines in the group Klaviyo AI follows and test your key URLs against them; the longest match wins, and Allow wins a tie.
  3. Look beyond the file. A firewall or bot manager can refuse Klaviyo AI even when robots.txt allows it, and that never shows in the file.
  4. Run our AI bot access checker to see how Klaviyo AI and every other crawler we track are treated in one pass, including firewall refusals.

Common mistakes with Klaviyo AI

The errors we see most often with Klaviyo AI in the files and firewalls we test:

  1. Assuming that blocking Klaviyo AI removes you from AI answers. It is a training crawler; AI answers are fed by retrieval and user-triggered crawlers with different tokens.
  2. Blocking Klaviyo AI with a broad User-agent: * rule that also catches search engines. Name KlaviyoAIBot in its own group instead.
  3. Expecting a Klaviyo AI block to remove content already collected. robots.txt only affects future visits.

All three hide inside a file that looks correct, so check Klaviyo AI from outside after every change.

Spotting Klaviyo AI in your logs

robots.txt says what Klaviyo AI may do; your access logs show what it actually did.

Count requests

On a server with standard Nginx or Apache logs, this counts matching requests per day (adjust the log path for your host):

grep -iE "KlaviyoAIBot" /var/log/nginx/access.log \
  | awk '{print $4}' | cut -d: -f1 | sort | uniq -c

And this shows which paths it requested most, which is the quickest way to see whether your Disallow lines are being respected:

grep -iE "KlaviyoAIBot" /var/log/nginx/access.log \
  | awk '{print $7}' | sort | uniq -c | sort -rn | head -20

Check the requests are genuine

Anyone can send the Klaviyo AI user-agent, so confirm the source before acting on a match:

  • KlaviyoAIBot: we hold no published IP list, so use reverse DNS where the operator documents a hostname and treat an unverifiable Klaviyo AI request with caution.
