There are many ways of image optimization for technical SEO, but this list will give you a good starting point. Test different techniques until you find what works best for your site.
What is image optimization?
Image optimization is decreasing the file size of an image without losing its high quality. This can be done in several ways, including using the correct file format, compressing the image, and using the proper image resolution. Reducing the file size of an image can help improve page load times, which can positively impact your site’s Technical SEO. In addition, optimizing images can help you save storage space and bandwidth.
1. Resize your images
One of the simplest ways to optimize an image is to resize it. This means changing the dimensions of the photo to make it smaller. This can be done in several ways, but reducing the image’s width and height is the most common. This can be done in several software programs, including Photoshop and GIMP.
Save appropriate format
Another way to optimize images is to save them in the appropriate file format. The most common file formats are JPG, PNG, and GIF. JPG is best for pictures with a lot of detail, such as photos. PNG is best for images with little detail, such as logos.
Choose the correct compression rate.
Choosing the correct compression rate can take time and effort. There are several different compression algorithms, and each has its benefits and drawbacks. The most common compression algorithms are JPEG, PNG, and GIF. JPEG is the most common, and it is best for images with a lot of detail.
Experiment with file types and compression rates to see what works best for each image. Many image-editing tools, like Adobe Photoshop and Adobe Illustrator, have a save-for-the-web option that automatically minimizes the file size while optimizing image quality.

2. Optimize image file names
Depending on your file type and compression rate, your image file name may also need to be optimized. This can be done by changing the file name extension or using a file name generator. For example, if you are saving your image in JPEG format, you can use the JPEG file name extension instead of the default .jpg.
3. Use alt tags
Alt tags are a crucial part of image optimization in technical seo. They allow browsers to display images not currently visible on the page. This can be helpful when trying to hide an image that is not needed on the page. In addition, alt tags can also be used to provide additional information about the image, such as the title or the caption.
4. Make images mobile friendly
Optimizing images for mobile devices is essential for several reasons. First, mobile users are more likely to use a slower internet connection. This means that photos need to be smaller to load quickly. In addition, mobile screens are smaller, so images need to be sized appropriately.
5. Optimize the image title
The image title is essential for image optimization. The tag provides additional information about the image, such as the date or the location. The label can also help improve the page’s search engine optimization. Therefore, the title should be descriptive and keyword-rich.
6. Include captions
Captions are an essential part of image optimization. They allow browsers to display images not currently visible on the page. This can be helpful when trying to hide an image that is not needed on the page. In addition, captions can also provide additional information about the image, such as the title or the caption.
7. Use unique images
Unique images are essential for image optimization. This is because browsers only display images currently visible on the page. Therefore, if you include too many pictures on a page, it will slow down the page. In addition, unique photos can be used to improve the page’s search engine optimization.
8. Ensure text complements the images
You should also ensure that the text on your page complements the images. This means that the text should be designed to be viewed alongside the photos. This can be done by using a font that is designed for portraits, using a lot of bold and italics, and using font sizes that are appropriate for the image.
9. Add image structured data
Image structured data allows browsers to display images not currently visible on the page. This can
be helpful when trying to hide an image that is not needed on the page. In addition, structured image data can provide additional information about the image, such as the title or the caption.
10. Use site maps
Site maps are a great way to your image optimization . They allow you to add photos to your pages and posts and provide search engines with additional information about your pictures. This can help improve the search engine optimization of your pages according to technical seo.
Make the most of your images.
Images can be a great way to improve the look of your website. However, if they need to be correctly optimized, they can also slow down your site. By following the tips above, you can ensure that your images are precisely optimized and keep your site running smoothly.
