Image alt attributes, often referred to as “alt text,” are descriptions added to the HTML code of an image on a web page. These descriptions are meant to provide context to the image for search engines and users who are unable to see the image. Alt text is crucial for several reasons:
Writing effective alt text is both an art and a science. Here are some tips to get it right (more can be found in the Google Forums):
While alt text is crucial, there are other important aspects of image SEO to consider:
Before you even upload an image, give it a meaningful file name. Instead of “IMG1234.jpg,” use something descriptive like “golden-retriever-park.jpg.” This helps search engines understand the content of the image.
Large image files can slow down your website, negatively affecting user experience and SEO. Optimize images by:
Ensure your images are appropriately sized for different devices. Use responsive design techniques so images scale properly on desktops, tablets, and smartphones. Implement the `srcset` attribute to serve different image sizes based on the device’s resolution.
Captions and surrounding text can provide additional context for your images. In fact, captions are often read more than the main body of text, so including keywords in them can boost SEO. Ensure the text around the image is relevant and descriptive.
Implementing structured data (schema markup) can enhance the way search engines understand your images. Use imageObject schema to provide detailed information about your images, which can enhance search results with rich snippets.
Lazy loading is a technique that delays the loading of images until they are needed (i.e., when the user scrolls to them). This improves initial page load times and can positively impact SEO.
Including images in your XML sitemap helps search engines find and index them. This can be particularly useful for sites with a large number of images.
Optimizing images for SEO involves more than just adding alt text. By paying attention to file names, sizes, formats, dimensions, captions, and structured data, you can enhance both the user experience and your site’s search engine performance. Remember, well-optimized images not only make your site more accessible and faster but also help you rank better in search results, driving more traffic to your site.
