Advanced website speed analytics & optimization tools in Lumar

The speed of your website has a significant impact on its success. Google has confirmed page experience as a ranking factor, and slower pages cause visitors to switch to competitors. This directly impacts conversion and bounce rates and, ultimately, revenue. Add to this that slow sites likely have higher content and resource storage costs, and it’s clear that the speed of your site can seriously impact your bottom line.

Example gives you not only full Lighthouse performance reporting at scale and origin-level CrUX data, but critically the details you need to understand the issues and take action, while improving collaboration across web development teams. All of which helps drive a high-performing, revenue-driving site that delivers a great experience.

“A key element for us has been Lumar’s customer-centric approach, and the opportunity to work collaboratively to help us meet our needs, from complex crawl segmentations to report and custom metric developments. It allows us to deliver a first-class service to our clients.”

Lucia Navarro, Organic Technical Director
“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.”

Kunal Sharma, Senior SEO Manager
Lumar gives us all the data we need to understand the technical issues impacting our search performance. The data is laid out in a really logical way, with high-level health scores and visualizations that make prioritization and communicating with stakeholders easy, backed up by all the detail we need when we need it. It saves us time and helps us make meaningful progress, which is exactly what we need.

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 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 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!”

Rod Cunniam, VP of Digital Insurance Solutions
“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

Dave Cain, Head of Digital Marketing, Arriva

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.”
