It’s important to know which image file type to use. It should be the first step before adding the image to your blog or page. We usually use PNG and JPEG file types. They both have specific attributes. PNG files produce better quality image but they are space intensive due to larger file size. JPEG files, on other hand, may relatively be of lose image quality but are smaller in size. You can also adjust the quality level to find a good balance.

2. Compress Images:

Google considers website loading speed as an important ranking signal. So your next consideration should be to reduce the size of your image files.

3. Use Unique Images

Uniqueness brings value even in case of images too. You can’t simply load your site with bunch of stock photos that present similar look and feel. Instead, go with some unique ideas to produce images that stand out and look pretty original. Discover other websites and consulting firms that run in your domain. From there you can get insight into the kind of images they are using. Avoid skip stock images even if they are well optimized. They can’t have the similar impact as of high-quality images on the website.

4. Avoid Using Copyright Images

It’s probably the first consideration. Beyond the size and quality of the photo, its originality comes first. Before uploading photos make sure they don’t violate copyrights. In case you’re using a licensed or copyrighted photo without permission, if you may be in legal trouble. Under DMCA you may come under scanner and can be served a notice if you’re reported to be in violation of copyright issues.

5. Use Custom Image Names

Like the way you provide Meta title and description for the pages / posts, Optimizing images with creative descriptions, keyword-rich file names and alt tags is absolutely crucial. An image must carry a name else it will be treated as an orphan element. Name of the image tells search engine crawlers what the image is all about.


Do not use default image names like “IMG_722019” or something similar. Google can’t distinguish it all. Change your image file name with a unique name that necessarily represents the purpose of your image. It helps search engines to understand your image and improve your SEO value.

6. Use SEO Friendly Alt Text

Sometimes browsers don’t recognize and render the image properly. This is where alt text comes into the picture. Alt is the text alternative to the image that describe the contents of an image file. You must have noticed that sometimes when an image isn’t loading, an image box is popped up in the top left corner with alt tag. Don’t underestimate the power of alt tag. It can embrace your overall on-page strategy.

7. Define Accurate Image Dimension

This is especially important if you’re using the images on AMP or PWA. In such cases, you must define your image dimensions in the source code. Even if it isn’t the case, have a habit to define the image dimensions. It improves the user experience and enables web browsers to size the image before the CSS is loaded.
