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 dave@tamethebots.com
Online Tools:
Fetch & Render
Fetch & render your pages, run a lighthouse test, check robots.txt
blocking & see the difference in the initial html & the rendered
DOM.
JavaScript / CSS Coverage
Find how much of your JavaScript & CSS files are actually used
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:
massWebVitals
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.
TwitterScreenShot
A Node CLI tool to make a screenshot of a tweet and create a link. A
twitter embed can add extra weight in JavaScript in a page, this allows
you to create a static image of a tweet from its URL, and a link to it,
which is much lighter.
There's been a few changes behind the scenes at {TametheBots}, we need to refresh to update the ServiceWorker:
