“I have been practising Search Engine Optimisation since the late half of the 1990’s when Alta Vista took notice of meta keywords — this was before Google started up! How things have changed over the years! I do a lot more than just Tech SEO though and can be hired by the day or on a contract basis.”

“The thing is you don’t really know where all the backlinks to your site are. No-one has a complete database of the whole internet - it’s just too big.”

A Chrome browser extension built by Simon Cox that analyses a web page’s JSON-LD schema usage, visualises schema type relationships using force-layout, circle, and tree diagrams, and suggests additional schema types based on page content.
“I built this extension to help me understand what Schema was being used on a page and what might be missing. This is still in beta but is available to test.”

“The extension reviews the content of the page and will make suggestions for any Schema that is not present based on the content of the page. This should help you decide what is pertinent for the page’s schema.”

Simon Cox’s methodology for measuring 301 redirect effectiveness by appending UTM parameters (utm_source=redirect, utm_medium=301) to destination URLs, enabling analytics platforms such as Fathom to attribute which old URLs still receive human traffic.
“I use Fathom analytics and it has a section in the dashboard for Campaign tracking. This is normally used for marketing campaigns where you want to track effects of adverts. Currently I have set the UTM tracking up as: source=redirect, medium=301, campaign=simoncox.com, content=last part of the old URL.”
Measuring the effectiveness of your redirects – published by Simon Cox
“So far since installing these UTMs I have not had that many hits on the redirects so they may not be as important as I considered, but I will leave it for a year or two before making any claims — and of course everything in SEO will have changed again.”

The process of preserving search equity, incoming links, and user traffic during website migrations by comprehensively redirecting old URLs to their new equivalents, preventing ranking loss caused by broken links or unresolved pages.
“When I work on a site migration I like to redirect everything I possibly can find, very much in a ‘no one gets left behind’ sort of way. Most migration projects don’t do this, for a multitude of reasons.”
Measuring the effectiveness of your redirects – published by Simon Cox
“If you look in your Google Search Console at any page you can find where they found links to a page. Sometimes it can be a URL on your site that vanished many years ago and isn’t even in the Google index. This usually means there is a page out there somewhere on the web with a link to the old URL on it.”

“I wanted a modular and automated way to add json schema to my personal website so built a set of templates and some simple logic to populate the schema.”

“For a long time Schema for web pages puzzled me. I had done a lot of research into it and whilst I grasped the fundamentals of why and how schema is formatted, actually making the decisions on what Schema to put on a page and website eluded me.”

About Simon Cox the technical SEO consultant based in the UK – published by Simon Cox
“As a child I always enjoyed making models, initally a three rail Marklin train set, that I am sure my dad bought for himself as much as me, and many Airfix kits. Then a family holiday to a little corner of North Wales occured and there I found the Ffestiniog Railway. That is exactly where my love of narrow gauge modelling started.”
