Search engines crawl your image text along with the content of your page during the search. Naming your files with targeted keywords that are clear and concise will help the search engine rank your page higher.

In addition to keyword-rich image names, use captions that include the key phrase or describe the image. Captions are visible on the page, so the users find them helpful, and the search engines’ ranking is affected by them.

2. Optimize ALT text and title tags

Alt text or tags are HTML code in place of your images. Search engines understand and assess your photos with these Alt texts and tags. 

Also, if not visible, Alt text or tags will appear instead of your images. Explain your images concisely and keyword-focused in the Alt text to improve ranking. 

Furthermore, title tags of images are similarly important, these are additional notes or explanations of ideas for the user, and to optimize your pictures better, you must add these too.

3. Reduce the size

For faster images, three standard file formats are JPEG, PNG, and GIF. You should pick the correct image format to upload depending on the use and image quality. JPEG files are smaller and supported by every platform, but the image quality may sometimes suffer. 

WebP is a new generation image format that is less in size but serves excellent quality. Most web browsers support it.

GIFs are preferable for smaller and simple images like icons or logos etc. PNG is the latest format, with excellent color accuracy and image graphics, but it might be heavy and oversized.

Using JPEG or PNG with simple images is an excellent option in file formats for webpages to combine quality and compressed size.

6. Use lazy load

A more innovative way of optimizing your site images is lazy loading. That means the image at last loads slowly while the top pictures load faster. This way, you can upload higher-quality images without frustrating visitors with a slow loading speed.

7. Avoid image CDNs

Image CDN or content delivery networks are third-party sites that provide hosting and uploading of your images on their servers. This will take the weight off your page and save your site’s bandwidth.

But that comes at the cost of removed backlinks and image blocking or deletion when the image CDN is jammed with traffic.

8. Use XML image sitemap

It will let the search engine find images loaded with JavaScript and increase the ranking in SERPs.
