Things to Consider While Optimizing Images for SEO

Reduce the Size Without Losing Quality

Using a large number of images on a high-resolution page can significantly slow down the download speed. Therefore, it is essential to reduce the size of the image without losing quality. You need to compress the images using styles. The image should be of the optimal size so that the loading of your site does not suffer. Optimizing your site’s images means making them easier, less heavy. When images are less heavy, the whole site becomes lighter. The low size image also takes up less space on your server and reduces the amount of data transferred when a visitor views your site. Which further will increase the overall performance. A faster website can lead to higher rankings in Google results; the better overall performance also improves your site’s SEO.

Use Responsive Images

Adaptability is not a luxury, but a necessity. It is important that images are displayed correctly on any device, from smartphones to high-resolution retina displays. To do this, the size of the images should correspond to the screen size of the device from which the user will view them. When the browser starts loading, it compares the ratio of the width of each image with the resolution of the user’s browser. It displays the one whose ratio of the width to the width of all versions will be as close to unity as possible. This saves traffic and improves speed. 


Uniqueness is one of the most significant criteria for getting a picture into the search engine services. Search engines do not only love not unique texts, but also graphics. Furthermore, they also try to present users the most diverse results without duplicate materials. You can purchase unique images in photo banks that specialize in selling graphic content, or create images yourself by editing free images on the Internet using image editors.

Select the Correct Image Format

The most commonly used formats are like JPEG, PNG, and GIF.  They are supported by all browsers and search engines. A light image of poor quality will create a bad impression and may cause a refusal to buy or leave visitors from the site. On the other hand, a high-quality image in high resolution can increase page load time. So, when choosing a file type for pictures, it is important to strike a balance between quality and size. Instead of JPEG and PNG, you can use the little-known WebP format. This format retains high quality with even smaller file sizes. JPG and PNG can be effectively compressed without loss of quality.

Fill in the Title and Alt Attributes

Search engines recommend always filling in the title and alt attributes. This is especially important for pages whose content consists mostly of images. Title provides additional information about the picture. Alt is an image attribute that contains an alternative text description. The contents of the Alt attribute are displayed instead of the image. Correct filling of the Alt attribute can increase the relevance of the pages, as well as the images themselves in the issuance of Images. The attribute is one of the strongest signals for search engines in determining image content. Alt should contain accurate and short image information. Try to make an alternative description of no more than 50-60 characters.

Sitemap.xml and Robots.txt for Images

In order for enabling the search engines to index images, they must be granted access to the appropriate directories in which these images are located. If the images of your site do not fall into the Pictures of search engines, check your robots.txt file. In addition to the main sitemap, Google recommends adding a sitemap-image.xml image map. 


Data from micro-markup can be used by search engines to determine the relevance of images to search queries. Add Image Object data for images on your site. The micro-markup will not only increase the visibility of your site in search services by Search Engine Images but also improve the site display when sharing on social networks. It will also increase its chances of getting advanced snippets.
