Image submission in SEO involves leaving images related to your website in different image sharing or submission sites. It entails choosing the right image, alt text, file format, and description. Image submission won’t work for you if you don’t sufficiently optimize your images. You need to have images that search engines can easily crawl.
It’s important that you always select images that are related to your industry or niche. Also, avoid using copyrighted images or anything with a watermark that isn’t yours. You can use sites like Flicker to find high-quality images without copyright restrictions that can get you in trouble.
Common image file formats include JPEG, PNG, and GIF. Most browsers support JPEG, but be careful to avoid data compression, which can reduce image quality. PNG typically has great resolution, while GIF images are normally used for logos, art, and animations. Alternative text, or alt text, is the text that visually impaired readers can hear read aloud to describe images. It’s also useful for SEO purposes. You should optimize in a similar fashion to file names. Create sitemaps to make it easier for search engines to gain more info about images. You can also add image information to your existing sitemap.
