Are you getting the Efficiently Encode Images error from Google Search Console or Core Vitals?

When it comes to making a website, images play a critical role in attracting and capturing visitors’ attention. They deliver a contextual message that enhances the user experience and answers the information the visitor needs. But in many cases, we use unoptimized high-resolution images, especially for WordPress sites. That’s something that needs to be fixed by each website owner. Because large images slow down your site, annoying the visitors by creating a poor user experience. So bringing the images to the correct size is critical for making your site fast. There are many ways to reduce the image size on your site, and one of them is known as efficiently encode, or encoding images.

This article will explain everything about efficiently encoding images, how they affect your site speed, and how you can encode images to display them on your site properly.

What does it mean to encode images efficiently?

Encoding images is generally referred to as image optimization for reducing the image size to a level that renders after and consumes less cellular data. So basically, encoding images is a way to compress an image to a smaller size without degrading its perceived quality. You can compress the images either using a plugin or manually, both ending up with a faster load time.  

Typically the compression level ranges between 1 – 100, from which 100 is considered as the best quality. Google Lighthouse scans all images with a compression level of 85%. Usually, images with a quality level of 75-90 are considered safer to deliver. At these levels, the images render faster, therefore, accelerating your site speed and performance. 

Efficiently Encode Images

Why do you need to encode images efficiently?

We know images are critical for making your site more engaging and interactive. But they are larger than standard text, taking a long time to load as compared to text. The larger the image size, the slower the page speed. When a visitor visits your page, the server takes more time to download images to show on the screen. Consequently, the visitors spend more time waiting for the images to be rendered. And when your website has multiple photos, it becomes even slower and frustrates the user and Google. 

To improve the page speed and performance, we need to encode or compress images to a size that renders them as quickly as possible. So when images are compressed, they take less space on the hard drive and it’s possible to create image-rich sites without using much bandwidth or storage space, making them faster. One of the significant advantages of optimizing images is that it allows you to retain the quality of the image while reducing the file size. So you can resize images without disrupting the image quality. Google uses speed as one of the ranking factors, so by compressing images you can improve your SEO and rank high on google. It also helps to create a faster backup. Collectively, It is an ideal way to provide a better user experience and attract more and more visitors to enhance your business. 

It is important to note that images make up a lion share of your speed issues and your sites overall weight, so make sure to optimize them for accelerating your site speed.
