How to Optimize Images for SEO?

There are various ways you can optimize your website images before adding them to make your website more SEO-optimized.

Responsive Images

WordPress version 4.4 comes with the native support feature for responsive images. With this feature, WordPress automatically creates several images of different sizes and fetches them to the users concerning the device they are using. You can also use CSS to implement responsive images if you are not WordPress user.   

The benefit of using WordPress for responsive images is that it speeds up the loading process for mobile users by making the file size smaller without distorting the pixels. 

Optimizing the File Name of Image

An accurate and content-related image is the first thing you must look at before uploading it to your website. The image you are looking to upload on your website should have an informative name, and make sure to blend the image description in the image name in the least words.

Optimizing the File Size of Image 

The smaller the image is, the faster the uploading time.

It is a fact that large images take a longer time to upload, which impacts the user experience negatively. There are a number of online image optimization tools available where you can easily reduce the image size without fearing losing image quality.

Image Alt Text Optimization

Image alt text is an essential element in order to get the best SEO results. The need for image alt text is due to the search engine crawlers as it is difficult to read the image or what it is all about.

Make sure to add high-rank keywords in your alt text so that when the crawler reads the alt text, it automatically accepts it.

Search engines have made advancements to increase the capabilities of crawlers, but image relative to alt text is still crucial to get productive SEO results.

Image Placement

There are many places on your web page where you can add images. But it is better to place the image where the search engine marks and counts it as a primary image.

It doesn’t matter how relevant the image is; if it is not with the proper placement, alt text, and image title, it will get unnoticed by the crawler.

Image Caption and Title Optimization

The search engine crawler not just goes through image alt text. The image caption and title have their essential. A relevant subject title and caption of an image help the crawler better understand the image.

So value the title and caption of images on your web page and include SEO-optimized text to get good SEO results.

Impact of Image on Search Engine Optimization

it is evaluated that now internet users look for images for queries and questions as images are an easy way to get the whole idea just by seeing it once; this is why Pinterest has more than 600 million searches every month.

Web developers use at least 4 to 5 images for every website design. So make sure that images you are adding to your website should be SEO optimized as search engine crawlers don’t read images that are not optimized. This is one of the primary reasons affecting the SERP ranking of websites.
