Google gives preferential treatment to websites that load quickly, the faster your site loads, the lower the bounce rate. If your site is fast, you have a better chance of ranking on the first page on Google over slow sites that drive high bounce rates. If you want to have a shot at ranking on the first page of Google, your site needs to load in under three seconds. Google offers the PageSpeed tool to find out what you need to fix but unfortunately, they don’t give you the best instructions on getting your score to 100%.
Getting your speed to under two seconds can double your traffic and revenue, the most common causes of slow pages are bulky images and unused code. Page weight bytes show the total size of a web page measured in bytes and Google’s benchmark data shows that the best practice for page size or weight is under 500KB.
JSitemap PRO integrates with Google to help you to identify issues and optimizations, but it has not tools to improve or fix them.
Speeding up a website is not easy task, here are the top four ways you can speed up your site and score a perfect 100% with Google:
Compress your images: use optimized images, for example in webp format, or use a third-party plugin such as JCH Optimize to automate this process. You can even lazy load images using specific plugins so that they re loaded only when the user scrolls down the page
Use browser caching: Joomla! has this feature in the core thanks to the page cache plugin
Minify your HTML: once again use JCH Optimize to automate this process
Implement AMP: it's a project implemented by Google to help mobile pages load faster thanks to a special markup and restricted features, you can use our great plugin JAmp to automate the conversion of your pages to the AMP format
