In this article, we will talk about image optimization. Then we’ll focus on the benefits of image optimization in SEO. At last, we would like to share some information on the process of image optimization. 

Why image optimization is necessary?

Image optimization is a technique for reducing the size of an image. This process mainly works on maintaining the quality of website photographs.

It provides the smallest possible image size. But it tries to deliver the highest-quality photographs in the proper dimensions and format.

So, image optimization is the process of dividing an image into smaller pieces and lowering its resolution. The main purpose of image optimization is to speed up the image loading time. The unoptimized image makes a heavy website. And a heavy or loaded website consumes a huge time to load.

It affects negatively website performance and decreases the loading time of a website. Nowadays, individuals would rather browse a website that loads quickly. As a result, the number of visitors to your website will decrease.

JPEG and PNG are two of the most frequently used image formats. Using JPEG results in a smaller-sized image, but you risk sacrificing part of the image’s quality in the process. 

You can also make modifications to get the balance and obtain the desired image quality. On the other hand, although PNG files are larger, they produce images of higher quality.

Benefits of image optimization

Images are often more essential than written content, particularly in social media. Attractive and fast-loading images play a significant role in gaining and keeping user attention. For fast-loading images, you need to optimize your website’s images.

So, you need to optimize all your site’s images in a proper format. With proper optimization, you can higher quality, leading to an undesirable impact on your content’s appeal. However, using the appropriate tools can prevent this issue.

Reduced Server Storage Usage

When images take less storage on your server, it becomes the most important benefit of image optimization. This not only saves you money but also supports you to reduce other expenses.

The disk space refers to the data capacity allowed by your web host. If your website contains numerous photos and media files, the required disk space equals the total size of all these files. The right file format and image compression type can decrease image size by up to 5 times.

Quicker Website Backups

Backups are very important for any emergency. Due to hacking, accidental deletion, migration to a new host or any other issue, you may need to have your backups. In this situation, it is very helpful if your image files are optimized.

Regardless of the situation, it shouldn’t take more than a few minutes to have your backup ready to go. Optimized images play a role in speeding up the backup process. It allows you to restore your site’s image files and other content swiftly.

So, the benefits of image optimization refer to the importance of SEO but also for ensuring a smooth recovery in case of a disaster or a change in web hosting.

Better Search Result Rankings

Your success in creating a WordPress website lies in having a higher position in Search Engine Pages. To gain this your website needs a higher ranking which mainly depends on how optimized your website is. Image optimization plays a role in enhancing this visibility.

Optimizing images is important because relevant images provide additional information for search engines. Large images can hurt your SEO rather than a positive one.

Search engines analyze and index images on websites. Large images that slow down the process can lead to lower rankings in search results. 

Reduced Bounce Rate

Bounce rate refers to users clicking on a site and leaving without any interaction. It is an important fact in improving your site. High bounce rates can negatively impact your online business or website. So, your main focus has to be on decreasing the bounce rate.

To decrease bounce rate you need to create a content-rich, furnished, and well-optimized website. To create a content-rich website, you just need to insert so many images in different formats. And the huge number of content or large images can slow load your website.

The major concern is a slow websites are the contributor to high bounce rates, as users tend to look elsewhere if content takes too long to open. Larger images significantly increase loading time.

So, to solve all these issues, you need to know about the benefits of image optimization to reducing page loading times and improve user retention.

Increased Traffic

Prioritizing image SEO can significantly boost traffic to your website. Optimizing images enhances the speed, quality, and relevance of your content, impacting how easily search engines discover, crawl, and index your images and, consequently, your entire site.

Achieving a high rank on Google is crucial for attracting more traffic, and SEO, especially image-centered SEO, plays a key role in this process. While it may vary for different businesses, image SEO holds more value for industries where imagery is a significant aspect of user searches, such as fashion, beauty, celebrity news, or travel.

Reduced Bandwidth Usage

Images consume a significant portion of the world’s bandwidth. Image optimization encompasses various aspects, including adjusting resolution, format, and dimensions to keep file sizes small. This optimization leads to decreased bandwidth usage.

While sufficient bandwidth is crucial for a website’s proper functioning, exceeding the limit can be problematic, causing your site to shut down and impacting your business. Adapting images to different screen sizes without adjusting their resolution is not ideal, as the saved loading time may be offset by increased bandwidth usage. 

How to optimize images for better SEO?

A lot of people are fond of searching for images online. So, images can gather so much web traffic and it is important for SEO.

There are specific ways to optimize images. Let’s have a look at these ways.

It’s important to assist search engines in understanding the substance of your image during this phase. Add alt tags to the images for this. Search engines can identify and show your images on SERPs because of alt tags.

These tags make it easier for visitors to find your website and photos online. <img src=“offload_media_plugin.jpg” alt=” offload_media_plugin_for_WordPress” />  is an example of an alt tag.
