Inspired by the posts of Kev Quirk and Jake Bauer, I did a Lighthouse test of my website. I wanted to see how good my blog is SEO wise. Some shortcomings were pointed out to me, for example I forgot to add rel="noopener" to external links with target="_blank" and in the mobile view some “tap targets” were too close together, so you could have clicked on the wrong one. I have addressed the problems and improved a few things in my theme. I don’t care that much about SEO, but somehow it’s nicer when Lighthouse confirms that you follow all the best practices, it’s the ambition. There are still a few things I could improve on, but I think then there is never an end.
To do a Lighthouse test, you can either use the “Audits” tab in Chromium-based browsers, or this bookmarklet in Firefox:
javascript:void(document.location='https://googlechrome.github.io/lighthouse/viewer/?psiurl='+escape(document.location)+'&strategy=mobile&category=performance&category=accessibility&category=best-practices&category=seo')
