PageSpeed Insights and W3C Compliance

Google PageSpeed Insights

As per Google’s definition: “These rules are general front-end best practices you can apply at any stage of web development”. In this sense, the score that you get from Google’s PageSpeed test does not tell you how fast your site actually loads, but how your site fares based on Web Optimization rules that advances the rendering and execution of front end codes (HTML, CSS, etc).

However, many of these rules are rather outdated for modern websites. If you ran the test against major websites like: http://www.facebook.com, http://www.microsoft.com, http://www.yahoo.com, you will get equally low scores.

Perhaps the only useful recommendation is the Optimize Image section. These are usually the major cause of slow websites. Please make sure to compress your images before uploading. Check out these image compression services and see what works for you:

W3C Compliance

Full compliance to W3C is not a strict requirement to make your website SEO compliant. W3C compliance simply implies that the HTML and CSS codes that your website is built is compliant with the standards set by the W3C.

There are several techniques used by Strikingly that the validator doesn’t understand, like lazy loading. It’s possible that if you load your site on W3C validators, it will tag lazy loading javascript as errors.

If you want your site to rank high in SEO, make sure that your site is regularly updated and has good quality and relevant content.
