While some of us might consider this quote a cliche but it doesn’t make it any less the truth, especially in the case of the online world today. 

As we know, the consumption of content is shifting towards the picturesque side of things consistently and continuously. Visual images are consumed 60,000 times faster than text. Which is why marketers cannot ignore the importance of images any longer.

When search engines index your web content they might not be able to understand the images but they do understand the text around it. Image SEO is all about optimising the images so that web crawlers can easily understand the images and rank them higher in the search results.

This can be achieved in several ways such as image file size reduction, contextual ALT tags and more. In this article, we are going to discuss all the things you can do to optimise your images.

So let’s get Started With Image SEO tips, shall we!!

1) Use Original & Beautiful Images

Why would anyone engage with an unimpressive image they’ve seen a million times? You should never post images for the sake of it instead, they should complement and support your textual content.

Your images should tell a story and leave a long-lasting impact upon the users. This is why creating beautiful branded images form the foundation of any image SEO strategy.


Although Google doesn’t frown upon the copied images still you should get your image made by your graphic designer or you can also hire a web design company. A truly unique and contextual image would enhance your user experience.

You can also find beautifully curated images from resources such as Pixabay, Unsplash, Flickr etc. 

2) Use Optimisable File Size

Having high-quality images is it great, however a lot of times these come with a large file size that negatively impacts your webpage load time.

You can reduce the file size while ensuring quality does not get affected by using online tools like Adobe Photoshop. Make sure all your images are within 500kb to ensure optimal loading speed.

Not only that, the file format (GIF, PNG, JPEG) is crucial while maintaining the file size and image quality balance. Since these file formats have a different compression rate and affect the quality differently, therefore, it’s file format should be per the image type.

Mostly JPEGs are the best for photographs, PNG’s for line drawings & texts and GIFs should be used for moving images. 

3) Consider Accurate Image Name

As we mentioned before search engine crawlers scan the text associated with the image to understand what the image is about. This is why establishing a well-defined image nomenclature is an important image SEO activity.

To name your images effectively the name should contain the main keywords and should also be short as well as relevant. The easier it is for search engine crawlers to scan your image, the more are the chance of the image to rank higher in search results.

Ranking higher in the search engine’s results is the best way to ensure the images readily reach your target audience. You can use the insights from your website analytics to find out how your target audience is searching for your product or services to name your images.

To create an impressive website caption, you should use them as image headlines. Keep the caption descriptive but short, and it should always be in the present tense.
