About Yannick Gaultier
Hi, I'm Yannick Gaultier, the developer of a number of open-source projects, most of them dedicated to SEO for common Content Management Systems or browsers. I regularly write articles on this site about SEO, Joomla, WordPress, or related matters. And when possible, I like attending conferences where I sometimes also speak about anything SEO.
Initially trained as a mechanical engineer, I fell into programming early on and never really looked back when given the opportunity to leave a career in a non-IT industry to become a full-time web developer.
All the projects I developed are open-source, usually GPL-licensed, with several being commercial as well.
Here are a few things I am working on or have done:
Open-source SEO projects
Extensions for Joomla
- 4SEO is an all-in-one SEO extension for Joomla. It's been developed from scratch as a single-page application (SPA) using the Svelte JavaScript compiler and Tailwind CSS. This client interacts with the host Joomla site only through a custom REST API, making it mostly platform independent. This lets 4SEO run equally on Joomla 3, 4 or 5.
- 4AI is an AI-powered Joomla assistant, capable of creating, modifying, or translating content, as well as posting to social networks, for instance. It's deeply integrated with Joomla 3, 4 and 5, and uses the same tech stack: Svelte + Tailwind + our REST API
- 4SEF provides customizable SEF URLs for Joomla and prevents duplicate content SEO issues. It can take over sites running sh404SEF. It runs the same on Joomla 3, 4 and 5 and is also built with Svelte and Tailwind CSS
- 4Podcast manages one or several fully-featured podcasts on a regular Joomla 3, 4 or 5 website. It also allows distributing the podcast to common platforms such as Apple podcasts, Google Podcasts, Spotify, or PocketCasts
- sh404SEF builds SEO-oriented SEF URLs (Search Engines Friendly URLs) for the Joomla CMS. It also has a number of SEO features, although it only covers a fraction of what 4SEO does. Started in 2005 and discontinued on August 17, 2023
- wbAMP was a from-scratch implementation of the Accelerated Mobile Pages specification for Joomla content. The first of its kind for Joomla, it received the Innovation of the Year award at JAndBeyond 2016 when initially released. wbAMP has now been discontinued.
- 4LOGS is a small utility extension with only one goal: easily find, view, and manage log files created by Joomla and 3rd-party extensions.
WordPress extensions
WeeblrAMP is a from-scratch implementation of the Accelerated Mobile Pages specification, released from early 2017. Fully-featured, including being the first WordPress plugin to support AMP forms and e-commerce active content, it was discontinued in 2023.
SEO browser extensions
SEOInfo is a tool for SEOs around the web, available on Chrome and Chromium-based browsers as well as Firefox. It analyzes pages viewed on the fly, providing a wealth of technical and SEO information. In addition, it will also detect errors such as broken links, invalid HRefLang tags, blocked resources, and much more.
It also includes a structured data validator, an AMP validator, and can audit pages using the full Page Speed Insight API. Right from an extension in your browser.
Other projects
ClearStatus is a Hugo-based status page generator. It generates a fully-featured status page website, including a Disqus-powered commenting system as a static site. It can very easily run on Netlify for free and powers Weeblr status page.
