The importance of properly optimizing images for SEO cannot be underestimated. If you want to learn more about general image optimization best practices, you can check out our resources. Today we’ll talk about such an important element as alternative text.
Alternate text is intended to help users with disabilities, such as people with low vision, use the Internet. Special programs read this text aloud, providing a description of the images.
However, alt text not only helps people with visual impairments, but also plays an important role in SEO. By not filling out the alt attribute for images, you risk reducing your site's visibility in search engines.
What is alt text for images?
Alt text is a description that explains the content of the image and its context. This description is present in the alt code attribute, and many people confuse it with the alt tag. The alt tag is code that includes a description of the image, but the text inside the tag is really all that matters.
The meaning of alt text is also obvious when an image cannot be loaded - in which case this text is displayed. Properly adding alt text is one of the best SEO practices for optimizing images on your website.
Why is alt text important for image SEO?
Every year, search engines are getting smarter in the way they process images. Search algorithms are now able to recognize the content of images and also take into account their context when ranking pages.
Today, images are an integral part of content on the Internet. For users, visual content is perceived much more pleasantly than just text. Google understands this too, and every year images increasingly occupy top positions in search results.
Search engines like Google are introducing new algorithms, including machine learning and augmented reality technology, to improve visual search results.
Alt text was also recognized as an important factor for SEO back in the early 2000s, and search engines have only increased their emphasis on it since then.
How to write alt text correctly
Alt text provides an opportunity to introduce keywords, but it is important to avoid overusing them. Here are some guidelines when writing this text:
- Describe the image as objectively as possible. Alt text is displayed when the image is not loaded, so it needs to be clear and precise.
- Make sure you provide context for the image. This will help search engines index your content correctly.
- Keep your description short and clear. For more detailed explanations, use the longdesc attribute. Remember that the word "image" can be omitted as it is obvious.
- Use keywords, but avoid using too many of them. Follow general content quality guidelines, including alt text.
