LINE OGP Scraper
LINE OGP Scraper is a generic scraper operated by Line. Intent varies case-by-case, some scrapers are legitimate research, some power useful aggregators, some are abusive.
Look at the request pattern before deciding what to do. A polite scraper crawls slowly, respects robots.txt, and identifies itself. An abusive one ignores all three.
If you are not sure, the safest move is to rate-limit rather than block outright. That keeps the legitimate use cases working while neutralizing the abusive ones.

1Should I let LINE OGP Scraper through?
Watch your logs for a week first. Behavior varies wildly. Observe the request pattern before allow/block decisions.
Does blocking LINE OGP Scraper affect my Google rankings?
No. LINE OGP Scraper is not a search-engine crawler. Your ranking on Google or Bing is unaffected by what you do here.
How do I confirm a request is really from LINE OGP Scraper?
Look at the User-Agent header in your access logs and match it against the strings listed above. Worth knowing that the User-Agent is easy to fake, so this check tells you "the traffic claims to be LINE OGP Scraper", not "the traffic is genuinely LINE OGP Scraper". If you need stronger guarantees, look for a reverse-DNS check or wait for Line to publish IP ranges.
What's the best way to understand what LINE OGP Scraper is doing on my site?
Look at which URLs it hits, how often, and what time of day. The request pattern usually tells you whether it's building an index, watching for a specific change, or trying to pull data in bulk. The User-Agent name alone rarely tells the full story.
How is LINE OGP Scraper different from Line's other bots?
Line splits work across multiple user-agents so site owners can decide on each one independently. Training crawlers, live-fetch agents, search indexers, and agentic browsers each get their own name. Worth scanning the rest of the Line family above to see which ones actually matter for your site.
What's the cleanest way to control LINE OGP Scraper?
Two layers. Robots.txt for the polite crawlers that read it, and rules at your CDN or edge for the ones that don't. Rankly's Agent Experience handles both from a single config, so you can allow, block, rate-limit, or serve a stripped-down version per bot. Agent Analytics handles the observation half so you know which bots are actually worth a rule.
