PageSpeed Insights
PageSpeed Insights (PSI) is a tool from Google that tests your site's performance on both desktop and mobile devices.
Keep in mind that, 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 advance the rendering and execution of front-end codes (HTML, CSS, etc).
However, many of these rules are rather outdated for modern websites. If you run the test against major websites like Facebook, Microsoft, and Yahoo, you will get equally low scores.
One useful recommendation from Google PageSpeed is the"Optimize Image" section. These are often a major cause of slow websites. Compressing your images before uploading may improve your PageSpeed. Check out these image compression services and see what works for you:
We also constantly update our site rendering technology to improve speed when testing with Google PageSpeed Insights. The majority of Strikingly sites now score over 90% on the Google PageSpeed test.
Note:
- You may have to run the test a few times to see improved scores! This forces the site to be recached, which improves load times around the world.
- If you add any third-party scripts or custom code, that may take extra time to load and run, and this may decrease your PageSpeed score.

W3C Compliance
Full compliance with W3C is not a strict requirement to make your website SEO-compliant. W3C compliance simply implies that the HTML and CSS code that your website built is compliant with the standards set by the W3C.
There are several modern, advanced website rendering 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 an error.
If you want your site to rank high in SEO, make sure that your site is regularly updated, has high-quality and relevant content, and gets quality backlinks by sharing and distributing your site.
