Crawler quality matters.
Crawling software is a foundational aspect of SEO, accessibility and website intelligence platforms — like Lumar. Website crawlers traverse a website’s pages to collate the raw data required for sophisticated website analytics and serve as the first step in understanding and optimizing a website’s technical health and organic search performance, and achieving compliance to Web Content Accessibility Guidelines (WCAG).
Our crawler is the cornerstone of Lumar’s website intelligence platform — and it’s consistently upgraded and enhanced with new releases to ensure fast, accurate, scalable crawls, and alignment with the latest search engine developments.
Ultra-Fast Website Crawling
Built for speed. Lumar’s site crawler leverages best-in-class serverless architecture design to drastically enhance website crawling speeds (as fast as your infrastructure allows).
For enterprise websites housing hundreds of thousands (or millions) of pages, Lumar’s ultra-fast crawling provides a major, time-saving boon for SEO, accessibility, digital marketing and developer teams, who previously could have waited days for a full website crawl to complete. Our latest crawler release allows for crawl speeds of up to 450 pages per second (and 350 pages per second for rendered content)—that’s very fast!
Flexible & customizable website crawls
Get the exact data you need. Our crawler offers extensive flexibility in data collection. The information that can be captured in Lumar crawls expands beyond technical SEO and accessibility metrics, paving the way for new built-in metrics and reporting options within the Lumar platform.
Users have access to 350+ built-in reports in Lumar Analyze , 300+ automated tests in Protect, and the ability to design countless custom extractions to collect data on just about any aspect of your website you can imagine. This flexibility allows for new use cases to be developed via Lumar’s crawler, with our recently released GraphQL API providing easy implementation for developers.
Get your first crawl underway in just four easy steps!

Heather Bidwell, SEO Manager
“Lumar Monitor has literally saved us hours a week. Instead of going to each site one by one and asking if work has been completed, I can quickly see if anything has been done and see the results and progress since then. It’s been a huge time saver and helped us see at a glance who’s been doing what. It’s been a huge, huge help.”
Joshua Taylor Titsworth, Senior Analyst, Fandom.com
“Lumar is a change enablement tool that’s helped us drive a +50% increase in digital conversion and +10% increase in search engine visibility”
Dave Cain, Head of Digital Marketing, Arriva
“The extra insights we get from our calls with Lumar have been really valuable. The support we get really is like having an extension of our internal team.”
Chris Nichols, Senior Manager, Enterprise SEO & Product Management
“Lumar has saved us an enormous amount of time. So much so, we estimate without the tool, and to cover the vast array of SEO analytics and insights highlighted within Lumar, we would have needed to employ another full-time member of staff within our digital team.”
Dave Cain, Head of Digital Marketing, Arriva UK Bus
“Lumar is fundamental when it comes to technical audits, as the tool carries out an in-depth analysis of each one of our brands. It provides insightful data that helps to shape our decisions. I love how easy it is to connect Lumar with Google Analytics, Google Search Console, and Majestic data for each of our brands. Lumar congregates all that data and makes my life a lot easier. Definitely valuable in helping us to identify the highest priority issues in a data set.”
David McAdam, Technical SEO Strategist
“Lumar is obviously top-of-the-line, with a lot of cutting-edge aspects to the technology. But it was also really important for us to find someone that would be a partner for us. The extra services are a big part of why we chose Lumar.”
Matthew Grabiak, Principal SEO Product Manager
“Lumar Monitor is everything any agency or enterprise-level company needs to quickly track and look at updates, recommendations, trends, and issues. If you have hundreds of sites, it’s a way to look at things at-a-glance and know exactly what’s going on — and what issues you need to be paying attention to.”
Joshua Taylor Titsworth, Senior Analyst, Fandom.com
“Lumar Protect is a very reliable tool. We used Protect, for example, to check if anything is redirecting where it shouldn’t be. Before, I had to check everything manually but, with Lumar, you can set up tests beforehand and really see what happens. It’s a great relief to know there is something that will notify me if anything has changed.”
