    “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 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.”

  • 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.”

  • 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.”
