Adding alt text to your product images is a great way to increase your ranking in Google Images.
Alt text simply means ‘alternative texts’ describes images. The best format for alt text is to make it descriptive and isn't stuffed with keywords.
Example, if you have someone read the alt text to you without looking at the image, does it reasonably describe the image? If yes, you're on the right track. Remember to create this description around your target keyword, of the page the image belongs to.
- Click on Add Image Alt Text button, found on the Image Optimization page
