Crawler operated by LINER
What LINER's crawlers are for
LINER runs 1 crawler in our database. Grouped by the job each one does:
- a training crawler:
LinerBot
The highest-priority token is Tier 2. That puts LINER among the operators whose crawlers have a direct effect on whether AI answers or search results can include your pages.
How site owners treat LINER
None of LINER'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 LINER
A robots.txt file cannot say "LINER"; it can only name LINER's tokens, one group at a time. With a single token, one group is the whole policy.
# One token controls everything LINER fetches through it
User-agent: LinerBot
Disallow: /private/
Allow: /- Decide per job, not per company. Training, search and user-triggered fetching have different trade-offs, even from the same operator.
- Name every token you mean. A token you leave out follows
User-agent: *. - Repeat shared rules. A named group ignores the
*group, so copy anyDisallowlines you still want it to obey. - Verify from outside. Run the GPTBot and ClaudeBot access check after any change to see the result for each LINER token, including firewall refusals.
Test yourself: does User-agent: LINER block all of LINER's crawlers?
No. robots.txt matches crawler tokens, not company names. Use the token LinerBot.
Test yourself: if you block one LINER token, are the others blocked too?
No. Each token is read separately. Blocking one leaves the rest following whatever group applies to them.
Each LINER crawler, explained
A one-paragraph brief for every LINER token in our database, covering what it does, how it treats robots.txt and how often large sites write rules for it:
- LINER AI (
LinerBot, Tier 2): a training crawler that collects pages both for training and for search or answers. Rated safe. LINER AI's operator does not clearly document how it treats robots.txt. Write the LINER AI rule anyway, then confirm in your logs that its requests stop. Not tracked in our robots.txt study.
Common mistakes with LINER's crawlers
The errors we see most often with LINER's crawlers in the files and firewalls we test:
- Assuming that blocking LINER'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.
- Blocking LINER's crawlers with a broad
User-agent: *rule that also catches search engines. NameLinerBotin its own group instead. - Expecting a LINER'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 LINER's crawlers from outside after every change.
What our own data shows about LINER
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 LINER's marketing. LINER has one token in our database, so the whole picture fits in one place.
LinerBot in our records
We first recorded LinerBot on September 22, 2026. LINER documents it on docs.getliner.com, and we recheck that page before each release. No file in our top-10,000 scans names LinerBot, so any rule you write for it puts you ahead of almost every large site.
Among the 104 AI and LLM crawlers in our database, LinerBot sits 60th by priority (Tier 2), level with AddSearchBot, AI2Bot, AI2Bot-DeepResearchEval, aiHitBot. 81 of the 104 share its safe rating. Other operators with a crawler that collects pages both for training and for search or answers: PerplexityBot (Perplexity AI, Tier 1), Andibot (Andi, Tier 2), Bytespider (ByteDance, Tier 2), cohere-ai (Cohere, Tier 2), DeepSeekBot (DeepSeek, Tier 2). A policy for LinerBot is usually a policy for these too.
A decision record for LinerBot
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 LinerBot entry reads:
- Operator and job: LINER; it collects pages both for training and for search or answers.
- Priority and behaviour: Tier 2, rated safe, blocking impact low.
- Suggested starting point: Your licensing call: Disallow to refuse training, Allow to permit it.
- Enforcement: LinerBot's operator does not clearly document how it treats robots.txt. Write the LinerBot rule anyway, then confirm in your logs that its requests stop.
User-agent: LinerBot
Allow: /Paste the line into the validator with one of your own URLs before it goes live. Revisit the LinerBot entry whenever LINER announces a change, because a Tier 2 crawler affects visibility directly.
Checking LinerBot on your own site
Because LINER runs only LinerBot in our records, one check covers the whole operator. Search your access logs for the string LinerBot 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 LINER publishes about the crawler, since that page is the only authority on its behaviour. A Tier 2 crawler rated safe is worth confirming every month, and our log checker does the counting for you.
How top sites treat LINER'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 LINER'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 LINER's crawlers too.
More questions about LINER
- Will blocking LINER affect my Google rankings?
- Only if one of its tokens is a Google search crawler. None of LINER's tokens are Googlebot, so classic Google rankings are unaffected.
- How quickly does a robots.txt change take effect for LINER?
- 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 LINER on some sections and block it on others?
- Yes. Inside the group for
LinerBot, addDisallowlines for the paths to keep private andAllowlines for exceptions. The longest matching rule wins. - Does blocking LINER delete content it already collected?
- No. robots.txt only controls future visits. For content already collected, check whether LINER offers a removal or opt-out process.
- Is a firewall block better than robots.txt for LINER?
- 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 LINER review
- 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.
- Decide the outcome per crawler. Use the briefs above to choose allow, limit or block for each token.
- Write the group. Add or edit one
User-agentgroup per decision and repeat any shared rules inside it. - Publish and wait. Allow about a day for crawlers to fetch the new file.
- Confirm the result. Check your logs, then run the LLM crawler checker to see the outcome from outside, including any firewall layer.
How to block or allow LINER in robots.txt
This rule covers the single crawler LINER operates. Add it to the robots.txt file at the root of your domain.
Block LINER completely
User-agent: LinerBot
Disallow: /
Allow LINER explicitly
User-agent: LinerBot
Allow: /
These LINER rules ask; they do not enforce. If a LINER token ignores them, block it at the server or CDN. Paths are case-sensitive, and each rule matches the token, not the full user-agent string.
Frequently asked questions about LINER
What crawler does LINER run?
LINER operates 1 crawler in our directory: LINER AI (user-agent LinerBot).
Should I block LINER?
Generally safe to allow; provides legitimate crawling value. The SEO impact score for blocking is 2/10, where 10 means blocking costs you the most visibility.
How do I block LINER in robots.txt?
Add the following to robots.txt at your domain root: User-agent: LinerBot then Disallow: /.
Does blocking LINER hurt my search rankings?
Blocking impact is rated: Low - No SEO ranking impact. Google's own ranking crawler is Googlebot, which this operator does not run, so blocking LINER does not by itself remove you from Google's index. What it can change is whether AI assistants and analytics tools can read your pages.
