I'll be nice and give the TLDR version at the top here so here it goes

Built a tool that runs the Google Lighthouse API every day, got a lot of data over two years, now making the data available to everyone

Dealership Website Performance Monitor | Dealer Data One

Ok story time and background on this all

A couple years ago now there was a collective question about core web vitals and how it impacts website performance for a user engagement viewpoint. So I built an overly complex tool that would run every single website (~1200) every day at random times of the day to truly measure the CWV metrics. It was an internal tool this whole time, but I made a quick and easy front end tool that simply called the lighthouse API

Did a couple case studies off of it, and no surprise CWV does impact overall site performance and user engagement and all of that, plenty of other vendors have published studies on that

BUT I was thinking the other day...we need an industry level report card. Information and data is so gate kept in some areas it was starting to rub me the wrong way and instead of gate keeping this information I wanted to make it public

So when you run your site in this tool it adds it to our list, spits out your immediate CWV scores, gives a little AI summary with CWV distro data, and then tracks and ranks it by OEM, Website Vendor, and eventually State/Region

If you have ever worked on the lighthouse API before or even tried running your own site through googles tool, you know that sometimes it can be a little slow, or occasionally wont return scores due to the API hanging OR because there isnt enough data on your site. So if you are sitting there going, man this is taking a while.... you are correct, but do not worry as that is the intended functionality

My end goal is to have a comprehensive industry report for every manufacturer and website vendor that shows overall performance and give a bit of a rankings list on who has the best performing dealership site in the Country depending on how we want to segment that.

There are still some manufacturers or website vendors that havent made it into the rankings so if you run your site and dont see any rankings data, do not fear, you are just the first of your kind

Anyway that is all, if you have feedback I am always open!

Couple other tools I have in the cooker that you can kinda play with now:
SEO and AI visibility tracker and ranker
Email and Domain Security Checker

Always free, not gonna ask you for anything. Maybe I need one of those links to buy me a coffee or something, or Celsius, the fridge is getting low on that and beer
 

✨ AI Highlights

A developer built an automated tool using the Google Lighthouse API to track Core Web Vitals daily across roughly 1,200 dealership websites over two years, and is now making that data publicly available through a free monitoring tool. The thread offers rare longitudinal CWV benchmark data for auto dealer sites, giving dealers and vendors a concrete way to see how their site performance compares across the industry.
