Andy Clear, Head of SEO
Lumar’s accessibility metrics have been a game changer. With its user-friendly design and comprehensive classification and description of issues, it has allowed us to quickly take action to improve our website’s accessibility and overall health, and it has been rewarding to watch our health scores steadily improve on the platform as a result.

Heather Bidwell, SEO Manager
“Lumar’s a huge time saver and really easy to use. I can see all issues in one place, know where to focus as everything’s broken down in a super logical way, and easily stay on top of progress with in-built tasks. Plus, the alerts catch any major issues before they lose us traffic or revenue. If you’re looking to boost your site’s technical health, Lumar and its amazing team have got your back.”

Arturs Cavniss, Technical SEO Lead
“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 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.”

Senior SEO Manager, European Fashion Retailer
“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.”
