Track this bot on your siteWhat is LinerBot?
LinerBot is the crawler for Liner, an AI research and answer engine. It indexes academic sources, blogs, and websites so Liner Smart Search can return answers with line-by-line source citations linking back to the original pages.
What LinerBot means for your site
LinerBot proactively indexes your site for an AI-powered search engine, operated by Liner. Unlike AI assistants that fetch on-demand, this bot discovers and catalogs your content so it can surface in AI search results. Being indexed means your content is eligible to appear when users search through AI platforms. Not being indexed means you are invisible in this channel.
What should you do?
- Allow LinerBot to crawl your site
- Ensure your most important pages are accessible and well-structured
- Monitor which pages are being indexed through crawl activity
- Review robots.txt to ensure you are not accidentally blocking LinerBot

BotSights tracks every LinerBot visit in real time, including which pages it crawls, how often, and from where.
How to identify LinerBot
LinerBot uses the user-agent "LinerBot" and respects robots.txt. It crawls systematically, similar to traditional search engine bots.
LinerBotlinerbotHow to block LinerBot
Three robots.txt options below. Pick the one that matches your goal. Each snippet lists every known LinerBot user-agent pattern so the rules apply regardless of which one the bot announces.
Edit robots.txt with care
A single misplaced line can de-index your entire site. Common mistake: pasting User-agent: * followed by Disallow: / blocks every bot, not just LinerBot, including Googlebot. Always paste the snippet between existing rules (not over them), keep the User-agent line scoped to LinerBot's patterns, and verify with Google's robots.txt tester before deploying. If you are not sure, ask a developer first.
Option 1: Block all access
Tells LinerBot not to crawl any URL on your site. Use this when you want the bot completely off your content.
User-agent: LinerBot
User-agent: linerbot
Disallow: /Option 2: Block specific paths only
Keep public content crawlable but exclude sensitive or non-public sections. Add one Disallow: line per path. Replace the example paths with your own.
User-agent: LinerBot
User-agent: linerbot
Disallow: /admin/
Disallow: /private/
Disallow: /checkout/Option 3: Slow down with a crawl delay
Crawl-delay is a voluntary directive that asks the bot to wait the given number of seconds between requests. Useful when LinerBot is hammering your origin and slowing the site down for real visitors, but you do not want to block it outright. The value is in seconds, so 10 means at most one request every ten seconds. Not all bots honour this directive (Googlebot ignores it; Bingbot, Yandex, and many AI crawlers do respect it).

Crawl-delay: 10Frequently Asked Questions
What is the User-Agent for LinerBot?
LinerBot identifies itself with the User-Agent string "LinerBot" (alternate forms: linerbot). Use this in robots.txt rules or server-side filters to control its access.
Should I block LinerBot?
Blocking LinerBot removes your content from Liner's AI search index. If you want visibility in AI-powered search results, allow it. The trade-off is similar to deciding whether to allow Bingbot or Googlebot.
Will blocking LinerBot affect my regular search rankings?
No. LinerBot indexes for AI-powered search, separate from traditional search engine rankings. Blocking it does not affect Googlebot, Bingbot, or your organic SEO position.
How do I verify a request is really from LinerBot?
User-Agent strings can be spoofed. Verify by checking the request's source IP. Check the operator's documentation for published IP ranges or reverse-DNS verification. BotSights does this automatically per visit.
Does LinerBot respect llms.txt?
llms.txt is an emerging proposal for AI-specific crawl guidance. LinerBot currently respects robots.txt, which is the reliable control mechanism. llms.txt support is operator-dependent and still evolving.
Is LinerBot different from Googlebot?
Yes. Googlebot indexes for traditional Google Search. LinerBot indexes for AI-powered search, which presents results as conversational answers with citations rather than blue link lists.
Will LinerBot affect my site speed?
Like any crawler, LinerBot consumes server resources. If crawl rate is excessive, set a Crawl-delay directive in robots.txt for this user-agent. Most AI search crawlers respect Crawl-delay.
