Image optimization is an often overlooked thing when positioning a site. If you do manage to take action in this direction, it is often limited to just adding the Alt attribute or resizing the graphic. What elements are important during optimization? Check out what you need to do!
1. Select unique images
Using original images gives you an advantage over competitors using image banks. If you sell products and add images from the manufacturer – there is little that sets you apart. In addition, your own images are more authentic, and for Google robots this is a big plus!
2. Choose modern formats
The best choices are formats:
- WebP,
- AVIF,
- JPEG XR.
These offer better compression and quality. WebP can reduce the file size by 25-35% without losing quality, which speeds up page loading.
3. Add Alt Text
Attribute Alt text describes the image content for search engines and users with visual impairments. Be sure to make it precise and natural – including 1 key phrase will be optimal With this attribute, our graphic or image on the page can appear in Google Image search.
4. Compress Images
Tools like TinyPNG can significantly reduce file size, which speeds up page loading and improves user experience.
5. Specify image dimensions
Defining the width and height of images in the HTML code prevents page layout problems, such as elements shifting when your page loads. Reserving space for images is a good habit.
6. Use key phrases in file names
File names with key phrases help search engines understand the image content. Instead of “img1234.jpg”, use a descriptive name, such as “green-shoes-in-panther.jpg”,which will improve your SEO results.
7. Implement lazy loading
Lazy loading, or delayed loading of images that are not immediately visible on the screen, improves site performance. This solution allows faster loading of content that is immediately visible to the user.
8. Add schema tags
Schema tags, especially on product and recipe pages, help search engines better understand the content of images. This can greatly enrich our pages in search results and encourage the user to click.
