Image Optimization with Alt Texts

  1. Understand The Difference Between Alt Texts and Image Title

    Image Title is a text showing up as you hover over the image. So far, it does not contribute much to SEO rankings than alt text, so you can include a call to action like “Click the image for more detailed information!” when the image links to the relevant page. However, you can duplicate the alt text to explain what the image is about. It is up to you! Keep in mind that alt text is designed to be read by search engine crawlers, so fill out alt texts carefully, or you will lose the benefit of image optimization.

  2. Name Your Images Briefly but Descriptively

    To have better SEO results, you must have a proper and keyword-rich explanation of the image in alt text. Make sure your images match the content and describe the image shortly without keyword stuffing. This is not only for the supporting images of your content, but also images for navigation to lead visitors to a homepage or other pages. In this case, you can put alt texts shortly like “Previous Page,” or “Back” on the navigation images.

  3. Don’t use Alt Text When The Image is for Decoration

    There are the images you should not put any alt texts. When images are used as decoration, there is no information to be described, meaning you can empty the alt text. Also, when you already explained the image in the body of the content, you don’t need to fill out or add the same things as the content. If you want to put something in the box, use a plain word.

  4. Use Different Alt Texts for Each Image

    When you have many photos in a content or show similar products, many people tend to use a generic text plus number, but this is not good for SEO. If the products have some specific code, use the product name and the product code. Or you can simply add several words to explain what the image shows.

  5. Pay Special Attention to Texts Around The Image

    Search engine crawler doesn’t read images by their own and they think the texts around an image are supposed to be related to the image. So you should prove that the image is related to the contents around by putting the same keywords or using captions. The best way is to describe details about the image just around the image.


Alt texts gives you SEO benefits and helps your viewers read contents properly. By using proper image optimization, it is possible to show your images in search listing pages and make your images search engine friendly.
