Crawler operated by Webz.io

What Webz.io's crawlers are for

Webz.io runs 1 crawler in our database. Grouped by the job each one does:

  • a training crawler: Webzio-Extended

The highest-priority token is Tier 6. That makes Webz.io a lower-priority operator for most sites: worth a deliberate decision, but rarely the one that decides your visibility.

How site owners treat Webz.io

None of Webz.io's tokens were among the names tracked in our robots.txt study of the Tranco top 10,000, which usually means few large sites write rules for them yet. Your own logs are the best evidence of how often they visit.

Writing one policy for Webz.io

A robots.txt file cannot say "Webz.io"; it can only name Webz.io's tokens, one group at a time. With a single token, one group is the whole policy.

# One token controls everything Webz.io fetches through it
User-agent: Webzio-Extended
Disallow: /private/
Allow: /
  1. Decide per job, not per company. Training, search and user-triggered fetching have different trade-offs, even from the same operator.
  2. Name every token you mean. A token you leave out follows User-agent: *.
  3. Repeat shared rules. A named group ignores the * group, so copy any Disallow lines you still want it to obey.
  4. Verify from outside. Run the AI crawler tester after any change to see the result for each Webz.io token, including firewall refusals.
Test yourself: does User-agent: Webz.io block all of Webz.io's crawlers?

No. robots.txt matches crawler tokens, not company names. Use the token Webzio-Extended.

Test yourself: if you block one Webz.io token, are the others blocked too?

No. Each token is read separately. Blocking one leaves the rest following whatever group applies to them.

Each Webz.io crawler, explained

A one-paragraph brief for every Webz.io token in our database, covering what it does, how it treats robots.txt and how often large sites write rules for it:

  • Webz.io Extended (Webzio-Extended, Tier 6): a training crawler that collects pages to train AI models. Rated caution. Webz.io Extended's operator does not clearly document how it treats robots.txt. Write the Webz.io Extended rule anyway, then confirm in your logs that its requests stop. Not tracked in our robots.txt study.

Common mistakes with Webz.io's crawlers

The errors we see most often with Webz.io's crawlers in the files and firewalls we test:

  1. Assuming that blocking Webz.io's crawlers 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 Webz.io's crawlers with a broad User-agent: * rule that also catches search engines. Name Webzio-Extended in its own group instead.
  3. Expecting a Webz.io's crawlers block to remove content already collected. robots.txt only affects future visits.

All three hide inside a file that looks correct, so check Webz.io's crawlers from outside after every change.

What our own data shows about Webz.io

Everything below comes from the AI Crawler Check bot database and our two most recent robots.txt scans of the Tranco top 10,000, not from Webz.io's marketing. Webz.io has one token in our database, so the whole picture fits in one place.

Webzio-Extended in our records

We first recorded Webzio-Extended on March 17, 2026. Webz.io documents it on webz.io, and we recheck that page before each release. No file in our top-10,000 scans names Webzio-Extended, so any rule you write for it puts you ahead of almost every large site.

Among the 39 data scrapers in our database, Webzio-Extended sits 37th by priority (Tier 6), level with Amazon Kendra, ApifyBot, Barkrowler, BLEXBot. 6 of the 39 share its caution rating. Other operators with a crawler that collects pages to train AI models: ClaudeBot (Anthropic, Tier 1), Google-Extended (Google, Tier 1), GPTBot (OpenAI, Tier 1), Meta-ExternalAgent (Meta, Tier 1), AI2Bot (Allen Institute for AI, Tier 2). A policy for Webzio-Extended is usually a policy for these too.

A decision record for Webzio-Extended

Teams that review crawlers once a quarter keep one short entry per token, so anyone can see why a rule exists and when it was last checked. Filled in from our data, the Webzio-Extended entry reads:

  • Operator and job: Webz.io; it collects pages to train AI models.
  • Priority and behaviour: Tier 6, rated caution, blocking impact low.
  • Suggested starting point: Your licensing call: Disallow to refuse training, Allow to permit it.
  • Enforcement: Webzio-Extended's operator does not clearly document how it treats robots.txt. Write the Webzio-Extended rule anyway, then confirm in your logs that its requests stop.
User-agent: Webzio-Extended
Allow: /

Paste the line into the validator with one of your own URLs before it goes live. Revisit the Webzio-Extended entry sooner than most: a caution rating means Webz.io traffic deserves a monthly look at your logs.

Checking Webzio-Extended on your own site

Because Webz.io runs only Webzio-Extended in our records, one check covers the whole operator. Search your access logs for the string Webzio-Extended over the last 30 days, note how many requests it made and which paths it asked for, then compare that with what your robots.txt allows. Match the requests against what Webz.io publishes about the crawler, since that page is the only authority on its behaviour. A Tier 6 crawler rated caution rarely needs more than a quarterly look, and our log checker does the counting for you.

How top sites treat Webz.io's crawlers

From our robots.txt study of the Tranco top 10,000 (5,583 valid files, fetched October 20, 2026):

None of the tokens for Webz.io's crawlers is tracked by name in our study. For scale, 20.1% of top-site files block at least one AI training crawler and 4.3% refuse every unnamed crawler with User-agent: * and Disallow: /, which would catch Webz.io's crawlers too.

More questions about Webz.io

Will blocking Webz.io affect my Google rankings?
Only if one of its tokens is a Google search crawler. None of Webz.io's tokens are Googlebot, so classic Google rankings are unaffected.
How quickly does a robots.txt change take effect for Webz.io?
Crawlers cache robots.txt, commonly for up to a day. Expect a change to apply within about 24 hours, and confirm it in your logs.
Can I allow Webz.io on some sections and block it on others?
Yes. Inside the group for Webzio-Extended, add Disallow lines for the paths to keep private and Allow lines for exceptions. The longest matching rule wins.
Does blocking Webz.io delete content it already collected?
No. robots.txt only controls future visits. For content already collected, check whether Webz.io offers a removal or opt-out process.
Is a firewall block better than robots.txt for Webz.io?
A firewall enforces the decision, while robots.txt asks politely. Many operators recommend robots.txt because blocking their IPs can stop them reading your rules at all. Use robots.txt first, and add a firewall rule only if requests continue.

A five-minute Webz.io review

  1. Confirm the token. Compare the user-agent in your logs with the tokens listed on this page. A close spelling is not the same crawler.
  2. Decide the outcome per crawler. Use the briefs above to choose allow, limit or block for each token.
  3. Write the group. Add or edit one User-agent group per decision and repeat any shared rules inside it.
  4. Publish and wait. Allow about a day for crawlers to fetch the new file.
  5. Confirm the result. Check your logs, then run the AI bot access checker to see the outcome from outside, including any firewall layer.
