Image SEO Best Practices
As you work on optimizing your images, consider the following best practices:
Choose the right file format
Select the appropriate file format for each image based on its purpose and desired quality. JPEG suits most photographs. PNG is better for transparent images or those requiring lossless compression. WebP is a newer format that offers superior compression and quality for both lossy and lossless images. It is an excellent option for modern websites. GIFs are ideal for simple animations and small graphics.
- JPEG (Joint Photographic Experts Group) is the most commonly used image format for photographs and other images with a wide range of colors. This format uses lossy compression to reduce the file size while retaining the quality of the image. JPEG images can also be saved with different quality levels to optimize their size and appearance. JPEG is ideal for photographs, graphics, and other complex images.
- PNG (Portable Network Graphics) is a lossless image format that supports transparency. It is ideal for images with simple graphics, text, or solid colors. PNG images can be saved in two formats: PNG-8, which supports a maximum of 256 colors, and PNG-24, which supports millions of colors. PNG is ideal for images with transparency or requiring high-quality graphics.
- GIF (Graphics Interchange Format) is widely used for simple animations and tiny graphics like logos, icons, or buttons. It supports lossless compression and a maximum of 256 colors. This makes it an excellent choice for small and simple graphics requiring animation.
- WebP (NextGen Images) is a newer image format that offers superior compression and quality for lossy and lossless images. WebP images can be significantly smaller than their JPEG or PNG counterparts, resulting in faster page load times and improved website performance. It is ideal for modern websites and is supported by most major browsers.
Use Alt Tag
An image alt tag, also known as “alt text” or “alt attribute,” is an HTML attribute added to an image tag. It serves as a short description that provides context for search engines and visually impaired users who rely on screen readers. Alt tags are displayed when images fail to load or when users hover their cursor over an image. They play a crucial role in helping search engines understand the content and relevance of your images, which ultimately improves your site’s overall SEO performance.
Why Are Image Alt Tags Important?
There are three primary reasons why image alt tags are essential for image SEO:
- Accessibility: Alt tags improve your website’s accessibility by providing context for visually impaired users who use screen readers. Including a descriptive alt tag ensures that everyone can understand and engage with your content regardless of their ability to see it.
- User Experience: Alt tags can enhance the user experience by offering a fallback when images fail to load. This can occur due to slow internet connections, broken image links, or users who have disabled images in their browsers.
- Search Engine Optimization: Search engines, such as Google, use alt tags to understand the content and context of images on your website. Properly optimized alt tags can help improve your site’s visibility in search engine results, driving more organic traffic to your website.
How to Optimize Image Alt Tags for Better SEO
- Be Descriptive: Write a brief but accurate description of the image that conveys its content and purpose. This will help both search engines and users understand its relevance.
- Use Keywords: Incorporate relevant keywords into your alt tags to improve your image’s ranking in search engine results. However, avoid keyword stuffing, as it can negatively impact your site’s SEO.
- Keep It Short: Aim for an alt tag length of around 125 characters, as screen readers typically truncate longer descriptions.
- Avoid Redundancy: Don’t use phrases like “image of” or “picture of” in your alt tags, as they are unnecessary and take up valuable character space.
Bad Practice (empty alt tag)
<img src="/dog.jpg" alt="">
Bad Practice (missing alt tag)
Bad Practice (Keyword Stuffing)
<img src="/dog.jpg" alt="dog, street dog, my dog, best dog">
Bad Practice (undefined file name)
<img src="/125422.jpg" alt="">
<img src="/labrador-dog.jpg" alt="Labrador dog">
<img src="/labrador-dog.jpg" alt="Labrador dog Playing with ball">
Optimizing your image alt tags with descriptive, keyword-rich text can enhance your website’s visibility in search engine results and create a more inclusive user experience. Don’t overlook the power of image alt tags as you work to improve your website’s overall performance.
Other Important Image Optimization
- Optimize image file sizes and compression. To improve website performance, reduce image file sizes by compressing and resizing them without sacrificing quality. Use image editing tools to optimize your images or online services and plugins that automatically compress images upon upload.
- Use descriptive file names. Ensure your image file names are descriptive and include relevant keywords accurately representing the image’s content. This will help search engines understand the context of your images and rank them accordingly.
- Provide captions and titles when necessary. When relevant, add captions and titles to your images to provide additional context and information. Incorporate relevant keywords further to improve the search engine visibility of your images.
- Implement structured data for images. Use structured data and schema markup to provide search engines with more accurate information about your images. This can improve your images’ visibility in search results and increase the likelihood of them being displayed in rich search results, such as Google Images.
- Utilize responsive images with lazy load for different devices. Implement responsive images using HTML5‘s “srcset” attribute or other techniques to display your images optimally on various devices, screen sizes, and resolutions. This will enhance user experience and ensure consistent image quality across different devices.
- Use lazy loading to defer the loading of images not visible in the user’s viewport. This technique can significantly improve page load times and overall site performance, leading to a better user experience and higher search engine rankings.
