5 Tips to Optimize Images for SEO



The majority of visual content on a website is in the form of images and a lot of searchers seek crisp and compelling visuals as an answer to their search queries, which they get through the image SERP of Google. These image results are linked to their specific website making it vital to not only create great image content but to optimize it through SEO for a higher ranking.


What is Image Optimization? 

Image optimization ensures that the images on the website are smaller in terms of file size yet serve a good quality. It also focuses on practices that optimise images to acquire a higher rank in the image SERPs. 

The major benefits of image optimization are:

  • Ensuring a visually appealing website. 
  • Having a quick-loading website.
  • Increasing traffic rate and diversifying traffic sources with more social sharing.
  • Enhancing the overall user experience with compelling image content.
  • Making sure that the google crawlers can identify and index image content accurately.


How to optimize images for SEO? 

Now that we are aware of why it is important to optimize the image content, it is crucial to have some direction for how to do it, so we bring to you, 5 Tips to optimize images for SEO. 


Tailoring File Name and Alt Text

Google crawlers do not view the image as the user does. It needs some other elements to better understand the image content. File name and alt text are two of them. They carry written content for the image which is analyzed by Google to better understand the context of the image.

By giving the image file a name that has pertinent keywords and writing relevant descriptions of the image in the alt text section, you cater to the SEO needs of your website, both on-page and technical. On-page SEO by ensuring the readers are aware of what the image is about, as the alt-text will appear in place of an unloaded image. Technical SEO by ensuring that Google crawlers are able to understand the context of your image to index it accurately.


Using responsive images

One size fits all does not work anymore. Different users use different devices to view your website, making re-sizing images as per the device it is viewed on, crucial. This is best achieved through responsive images. 

Responsive images apply the art of customization, in order to cater to a wide range of traffic coming from a plethora of sources. Various CMS platforms re-size the images automatically depending on the device. But, in the case of websites built from scratch, codes are added to ensure that the image adjusts as per the device it is being viewed on.


Compressing Images

The file size plays a major role in the loading speed of a website. A heavy image, taking a major storage space, will impact the overall page loading speed resulting in a bad user experience. A slow-loading website is one of the biggest reasons for a high bounce rate. Therefore, compressing images is crucial.

Compressing the images reduces their file size without compromising on the quality. Choosing the right file format is one of the best ways to compress images optimally. JPEG is great for images with heavy colours and PNG is best suited for images that are simpler. They can be further compressed with a plethora of online tools.


Sitemap submission

Sitemaps serve as a roadmap for Google to discover and identify the content on your website. Since images are viewed by Google differently, the process can take time. But, by submitting image sitemaps, you can accelerate it. 

It can be done either through the plugins available on the CMS platform or manually on the Google search console. By submitting image sitemaps, you direct Google bots to crawl through the image content on your website, understand its context and index it accurately. In the long run, this helps you in being discovered by the pertinent audience for your targetted keywords, as a result of which, you not only enhance the traffic quantity but also it’s quality.

Webpage content alignment

If your image content does not align with the other content on the webpage, then it is harmful to both user experience and SEO. Misaligned images will be viewed as irrelevant by the user, making your webpage look unorganized. And, for Google crawlers, it would be difficult to link your image content with the overall content on your page, resulting in inaccurate indexing eventually causing a drop in your ranking. 

The only prevention to this is creating image content that is relevant to the overall theme of the webpage and, making sure that the information in the file name and alt-text is pertinent. This step must be exceptionally taken care of while publishing images in blog posts.



Creating and optimizing images play a major role in enhancing your website’s visibility and indexability. Well-optimized images ensure a good user experience and improve your rank on the image tab of the SERPs. But, just like SEO, image optimization also requires consistency and patience to yield results.
