Why is everybody so obsessed with Google Insights score? Because it matters! The test results are an important SEO factor, and Google Insights is a valuable tool for measuring your website usability.
We will teach you how to optimize and use your images if you want to improve your Google Insights results.
Use properly sized images
When ShortPixel users ask us to help them with Google Insights scores we usually answer that “one problem noted by Google is related to using images that are too large for their placeholder”.
For example, if you have a 2,000px x 3,000px image which is scaled down to 600px x 700px then Google will tell you also that “Properly formatting and compressing images can save many bytes of data.”
Here is an example of how such an oversized image appears when you click mouse-right and check “View Image Info” option:
Adjust the size of these images and then your Google Insights score should improve.
Use lossy optimization
There are very few situations when lossless optimization is needed. So, we strongly recommend you to use the lossy option if the speed of your website is important. If there is an image that you don’t like how it was optimized you can always optimize it again as lossless or restore it, if you have Image Backup option active.
Check the cache issues
Your website sometimes serves old, non-optimized images if you use a cache plugin or if your host provider has a caching solution.
If you suspect that an image is not optimized, the easiest way to see if it is a cache issue is to add “?something” at the end of an image URL, then the caching is overridden and the actual optimized images is read: http://unoptimizedimageurl.jpg?something.
So, after you optimized your images be sure that you refresh your cache and if the issue persists please ask your hosting provider to do the same for your website/webserver.
Images from other sources
From time to time, you use images from other sources like the logos of various services or hot-linked images from other websites. Check if these images are optimized and if they are the reason your page is loading too slow.
Remember: Google Insights is just a tool
Google Insights doesn’t look at your website, and it cannot judge which is the proper image quality of your images. What it does is to automatically analyze your web pages and compare them with some good practices.
We made several tests, and we adjusted our image optimization algorithms to have the best compression without compromising the image quality. Of, course you can process your media files again and again, and stretch them with few more bytes, but that won’t help much because if an image is optimized multiple times it will start to show visible artifacts. And that’s not something you’d want to happen, right?
We encourage you to use Google Insights and also to apply the advice from this article, but 100/100 points on Google Insights test is not your goal, having a good website, with good content and happy visitors is what matters.
