Core Web Vitals Rankings - I spent way too much time on this to rank 1300 websites

[dealerdata1]

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

This is great work and I'd add one column to the report card that Lighthouse can't see: the no-JS word count. Fetch each homepage and a VDP without executing JavaScript and count the words that come back. GPTBot, ClaudeBot and most of the AI answer engines don't run JS, so that number is literally what they read.

We did this for our own category last week. Three vendor sites in our space returned under ten words to a plain fetch. Full marketing site, zero words for a crawler. And I'll own ours: our homepage was a React app shipping 317 crawlable words until we fixed it. Perfect CWV, invisible to half the crawlers that matter now.

The reason it belongs next to CWV is that the correlation runs the wrong way. The fastest dealer sites tend to be the most client-rendered ones, so the green Lighthouse score and the empty crawler view show up together more often than you'd think. If your tool already fetches 1,300 sites a day you're one flag away from the first industry number on it. Happy to share the fetch we used.

Funny you mention it but the tool does actually fetch this data, we just don't expose it yet.

It will certainly be part of a larger case study once I can get more dealers in this and a wider variety of website vendors. But some website vendors really like blocking bot crawls.

I foresee a secondary CWV-esque data set living besides Mobile and Desktop CWV metrics that will be AI/Crawl focused metrics.

Hoping we can get the industry wide report out by year end on this, but all in due time
