    “Lumar gives you everything you need for website analysis in one place, clearly laid out, rather than using multiple sources or overwhelming you with data. And the Lumar team is really friendly, helpful, and responsive. If I have any questions, they get back to me straight away, so I don’t have to wait weeks to respond to simple questions. Working with both the Lumar platform and team really is seamless.”

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.”

    “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.”

    “Lumar removes unknowns so you can make more informed decisions. With the health scores, I can get an instant, at-a-glance view to see the impact of changes, delve into the details, and fix any issues immediately. I’m on the platform so regularly it’s one of the few passwords I still know!”

    “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.”

    “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.”

    lumar customer review for technical seo analytics tool

    “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

  • Cox automotive

    “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 heart

    “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
