Technical SEO Tools
A small collection of some technical SEO tools I've put together, mostly for my own use, and often to learn how something works, but I hope you'll get some use out of them.
If you have any suggestions, I'd love to hear from you at email@example.com
Fetch & Render
Fetch & render your pages, run a lighthouse test, check robots.txt blocking & see the difference in the initial html & the rendered DOM.
Robots.txt Testing Tool
Test a list of URLs against a live or custom robots.txt file.
Lost GSC Impressions URL Inspection
Get URLs that have lost impressions in Google Search Console, and test them with the URL inspection API.
Real Googlebot IP?
Test an IP address to see if it's really Googlebot.
Desktop / Mobile Link Diff
Check the links on a page when visited with a mobile user-agent compared to a desktop user-agent.
Desktop / Mobile SD
Test for differences in meta & structured data between mobile & desktop user-agents.
Tools & Scripts on Github:
A node CLI script to grab Largest Contentful Paint, First Input Delay & Cumulative Layout Shift for a list of pages specified in a .csv file. The script will load the page, scroll down it's entire length & capture a video in .webm format, with the CWV overlaid (in most cases). It will then produce a .csv value with the test results for each URL, and a reference to the video file.
