Tips for Image Optimization for website

Do you want to improve your SEO? If your image optimization is lacking, you may be losing traffic, customer engagement, and sales.
When determining which website to rank for a certain search query, Google considers over 200 variables. While having a well-optimized image will not help your subpar content rank first, it will help you stand out from other sites that do not optimise their images.

What’s the good news? Seo strategy is not particularly difficult. Just a few adjustments to your current image process could increase traffic and leads, leading in more revenue.

Why Is Image Optimization Important?

Image optimization improves visibility in Google, resulting in increased traffic. That is the primary reason sites should optimise their photos, but there are numerous other advantages as well:

  • Enhance the user experience: Images that are well-optimized and displayed correctly increase UX by making your site easier to navigate. Large photographs, for example, can fill up the full screen or cover other website elements.

  • Increased site speed: When it comes to SEO, speed is everything. Images that are too large or wrongly formatted might slow down your site, hurting your ranking and upsetting users. 

  • Increases the accessibility of your website: Some SEO actions, such as adding alt tags, can help screen readers navigate your site more easily. Web accessibility benefits not only site visitors but also SEO.

While image optimization may appear to be another another step in the never-ending drive to improve SEO, it has the potential to have a big influence on ranking and UX.

How can you ensure that graphics aren’t slowing down your site?

7 Image Optimization Tips for Your Website

Technical SEO can be challenging if you don’t understand the most recent Google algorithm adjustments and what they mean. Images aren’t as complicated as other aspects of SEO, and they don’t tend to change as much, which is a positive thing.

It is now up to you to ensure that your photographs aid in SEO. Here is what you need to know.

1. Choose the Right Image File Type

Using the incorrect picture file format can cause your photographs to appear grainy, difficult to view, or even impossible to see. You can also utilise vectors, JPEGs, and raster images, as well as PNGs and GIFs, to improve the look of your photographs.

Which picture kind is excellent for SEO and which is not? Most of the time, use JPEGs or PNGs.

JPEG stands for Joint Photographics Expert Group. It’s a standard method of storing an image file. They can be seen on almost any device and can display a wide range of hues, so they preserve the colours of your photographs.

Because some information is lost when JPEGs are compressed, they are not the ideal choice for professional photography. They do, however, function nicely as featured photos in blog articles and other types of photographs.

People do not only use this style of graphic. PNG images can be viewed on any device. In this scenario, they use lossless compression, which ensures that no data is lost throughout the compression process. They can also include components such as transparent backgrounds. However, the file sizes are frequently substantially larger.

A) For blog post images, screenshots, and so on, use JPEGs.
Smaller images will help the site load faster, and the majority of them will be clear enough to utilise on the site. You can use PNG if the quality isn’t good enough and your web speed isn’t too slow.

B) Use PNGs for icons, logos, and images that may be zoomed in.
PNG files are larger but have a somewhat greater quality. Use a PNG file when image quality is crucial.

Other image types, notably GIFs, should be avoided on your website. I appreciate a good GIF, but they do slow down your site.

2. Compress Your Images

Compressing photographs reduces their size, making them easier to load on the Internet or store on your computer or smartphone. This facilitates the movement and storage of photos. If compression is done correctly, it is possible to make an image smaller while also improving its quality.

The two methods of image compression are lossy and lossless compression, and they both lower the size of the image. JPEGs use lossy compression, which means that some data is lost. In contrast, lossless compression retains all of the data. (As previously stated, PNGs are lossless.)

You must select the sort of compression to employ based on the type of image you wish to save.

3. Add Description Alt Text

Alt text (alternative text) is a written description of an image that tells people what it is and why it is there. It also explains how it works. Based on this data, a screen reader informs its users about images, and Google utilises it to determine whether an image is related to a search query.

If you utilise the WordPress platform, adding alt text to your posts is a breeze. It’s simple: Simply click on an image block and type “alt text” into the box.

When you right-click a picture and select Alt text, a box will appear in Google Docs. You can provide alt text in this field.

That is your alt text. What exactly do you write there? Your option, however here is the formula I use:

“The important word is “picture description.”

I used “image optimization guide alternative text” as just a text links for the picture above, which comes from WordPress. When you save a picture in this format, assistive technologies can recognise it and Google can notice that it is related to image optimization web searches.

To observe how your competitors utilise alt tags, go to their website, right-click, and select “Inspect,” then examine their alt tags. The code on their website will display alt tags.

4. Write High-Quality Image Names and Descriptions

Your picture titles provide people and search engines with additional information about them. According to Google’s John Mu, they don’t directly effect how well your site ranks, but they do add a little extra information and appear in your site code.

I believe it is best to include a brief explanation of the image as well as the major keyword that your post is about. This is comparable to your alt text.

The title and snippet that Google generates for images can also help people locate your photographs when they conduct an image search on Google. If you give it a title, they will consider it.

5. Ensure Images Are Mobile-Friendly

If you utilised the correct file format and compressed your photographs, they should be visible on phones and other small devices. However, things don’t always turn out the way we expect.

Because mobile devices account for more than half of all internet traffic, you must ensure that images do not degrade the experience for individuals who use their phones to access the internet.

As a result, I believe it is critical to test your site on a variety of mobile devices to ensure that the photographs look their best. Keep in mind that your photographs may appear differently on tablets, iPhones, and Android devices.

Use Google’s mobile-friendly test to ensure that your photos aren’t slowing down your site’s mobile speed.

6. Use Schema Markup

Some refer to it as “formatted data.” Schema markup, commonly known as “structured data,” is a sort of code that aids search engines in comprehending your data.

It’s likely that you’d like to compile a cookbook of family recipes. Because everyone makes their favourite food differently, you send out a form asking your family to register their recipe.

So now you can see everything you’ll need to make the recipe, as well as how much of each ingredient you’ll need and how long it’ll take to prepare.

That is essentially what schema makeovers accomplish. It assists Google in determining what type of data you have, such as a list, a recipe, a picture, and so on.

7. Optimize Image File Names

According to Google, it looks at the URL path and the file name to better comprehend your images. This implies you should organise your image URLs logically and include significant words in the file name.

It both helps you keep track of stuff and helps Google comprehend your photographs, so it’s a win-win situation!

A file name does not have to be very long. As a general rule, I use the alt text as the file name, which makes adding posts to WordPress easier.

I believe it is a good idea to include the keyword in the file name and to describe the image.


In this article, I discussed 7 image optimization tips with the purpose of improving page load time and user experience:

  • Choose the best file format for the intended visual impact.
  • To ensure that photos load quickly, use progressive JPEGs and next-generation file formats.
  • Use caching on both the client and server sides to minimise unnecessary image reloading.
  • Use compression to minimise file size without sacrificing quality.
  • Before displaying photos to users, resize them to the right size.
  • Use content delivery networks to optimise image distribution (CDN)

I believe these suggestions will assist you in reducing page load time, increasing user satisfaction, and increasing conversions and revenues on business websites and web applications.
