What is Linespider?

Linespider is LINE Corporation's search engine crawler. Linespider is a Web crawler that provides a wide range of search results for LINE services while complying with the Robots Exclusion Protocol. https://help2.line.me/linesearchbot/web/?contentId=50006055&lang=en.

Linespider powers a search engine, and search indexes increasingly feed AI answers and overviews alongside classic results. The pages it can crawl are the pages eligible to rank and to be pulled into AI-generated summaries, so allowing it protects both your SEO and your AI search visibility.

Like any automated client, Linespider consumes crawl budget and appears in your server and CDN logs. Reviewing those logs alongside your robots.txt rules helps you keep automated traffic deliberate and easy to reason about.

Want to see every AI bot hitting your site? Promptwatch turns your server and CDN logs into a live view of AI crawler and agent traffic, so you can watch ChatGPT, Claude, Perplexity, Gemini, and others crawl your pages and connect those visits to real citations and revenue.

How to handle Linespider

Most sites keep Linespider allowed, because blocking it can remove your pages from the search results and AI answers it powers. Only disallow it if you specifically want to opt out of that surface.

To control Linespider, add a rule for its user agent to your robots.txt:

User-agent: Linespider
Disallow: /

LINE Corporation does not publish a robots.txt commitment for Linespider, so confirm how it behaves by watching your access logs.

Examples

  • After publishing a new comparison page, a marketer checks whether Linespider has fetched it so the content can appear in search results.
  • An SEO lead keeps Linespider allowed in robots.txt to preserve visibility in search and AI-powered answers.
