DeepcrawlはLumarになりました。 詳細はこちら


The Lumar website intelligence platform is used by SEO, engineering, marketing and digital operations teams to monitor the performance of their site’s technical health, and ensure a high-performing, revenue-driving website. 

The cornerstone of our platform is a website crawler, which crawls a site’s pages to collect data for sophisticated website analytics. 

We obey the Robots.txt protocol and will not crawl your site if you exclude the Lumar user-agent token, e.g.

User-agent: deepcrawl
Disallow: /

The IP addresses and user-agents used by Lumar will change from time to time depending on user settings, as this is sometimes required for specific testing processes. Please note that our user-agent currently references our previous company name (Deepcrawl) to avoid creating issues for our customers. This will be updated to Lumar in due course.

If you have already excluded the Lumar user-agent but your site is still being crawled without your permission and you would like it to stop, then please contact us at
