3. CVOptimize image alt tags

 Alt tags provide the alternate text or information of an image, if the image cannot be displayed or if the user can’t be able to view it for some reason. Each image on your site should include unique alt tags which describe them with the relevant keywords. This also makes your image alt tags SEO-friendly.

Therefore, you should aim to accurately describe your images with the keywords for the page it is on.

4. Resize Your Image

If you have images on your site that take a longer time to load, you’ll less likely to convert visitors. Since large image files take more time to load and reduce overall page loading speed, the user experience of your website will get affected.

There you have compression tools or plugins (if you are on WordPress) to help you compress the heavy loading images. By the rule of thumb, it’s best to have an image under 70kb.

5. Choose the right image format

Before you upload any images on the site, consider choosing the right format. There are various image files including jpg, png, gif, webp, if, etc. WebP is considered to be a modern-day image format optimized for small size and quality images. Using webp images, web developers are able to create smaller and rich images to make web pages load faster.

Besides WebP, you can choose to have a jpg format especially if you have tons of images on your website. JPG image formats take the least space without compromising the quality of an image.

If you couldn’t able to convert images to jpg, png is another great alternative to consider for image SEO. PNG provides you wider support for image transparency and palette-based photos. Moreover, GIF also uses a lossless compression technique to reduce the file size without degrading the visual quality.

Captions are the one-liners used as short text placed below an image to describe it to the site visitor. Creating eye-catching captions increases user engagement so as to make readers more likely to read the content.

So, it’s the best practice to add captions below images to make them stand out. It’s recommended to add keywords while writing caption because it will help in improving your domain authority and your website’s visibility.

Another proven way to optimize your images is to serve them through CDN. CDN services is also popularly known for hosting images and videos for websites.

There are several CDN services you can use if your website gains higher traffic. CDN will do wonders for you in terms of boosting page loading speed and improving page SEO by reducing the distance between your hosting servers and your users operating a site.

8. Add structured data to your image

Adding structured data helps search engines to crawl and understand the content. So, if you’ll add structured data to your images, you’ll help search engine to understand your images and rank them faster.

If you want most of your images to show up on search results, add structured data to all the images. Structure data is well organized and easily recognizable by search engines.

9. Don’t let images hide text on the website

Hiding text content on a website using images is considered a black hat SEO technique and comes with penalties. For instance, covering up header text using an image in place of the headings.

If you really want to use an image instead of text as your header, make sure to label the image to get the benefits of image SEO.

10. Incorporate title tags

In addition to alt tags, you should also include title tags as a part of optimizing your images for SEO. Unlike alt tags, title tags will not take the place of images that can’t be displayed. Instead, they pop up when users hover their mouse over an image.
