Ask Yoast: Using your keyword in the alt text box

At Yoast, we firmly believe that websites should be usable by everyone, including people with a visual impairment. The alt textbox plays an important part in this, as it clarifies the content of an image. Visitors of your site that use a screen reader can listen to the alt text read aloud, to better understand the value and function of the image. So, you should make sure that the alt text sufficiently describes the image.

Besides improving accessibility, the alt text also helps search engines determine what’s on the image, which influences how the image ranks. So, should you add your keyword or keyphrase in the alt text to improve your ranking? Let’s go into that for this week’s Ask Yoast!

Stephen Stefanski emailed us his question:

Some people told me you should never put a keyword in the alt text box. I think I actually should. What do you advise?

Watch the video or read the transcript further down the page for my answer!

Using your keyword in the alt text box

“Well, the alt text box is meant to say, “Hey, this is on this image”. And if you can describe that image using a keyword, then yes you should.

If you cannot describe the image using the keyword, then no, you should not. It’s that easy… Good luck.”

    This is true, I only put keywords on alt text box when the image is clearly define what is on the image.
    If it’s irrelevant, then I wouldn’t put any keyword on the alt text, just what the image is about.

    Thank you for this post, I totally agree.

      Hi! Glad you liked the video! Just a tip: while you don’t have to be afraid to use your keywords in the alt text, you should make sure the text fits the image, and of course, don’t spam too many keywords in the alt text ;-) Stick to that and all will be well :-)

    I always use image alt text in my articles. I also like to include my keyword in the alt text.

    These will help users understand my content better and may help me rank higher also.

    Hey Joost!

    I always use Alt Images Text. It is helpful, as you’ve mentioned here. You are not only helping those people, but you are also helping your content rank higher because of this.

    I have not heard that advise to actually describe what’s on the image in the alt text. This is new advice to me. This is very interesting and helpful Thank you so much for sharing that!

    Best regards! :D
