Alt text, or alternative text, is an image description that comes up when the image can’t be loaded. It’s useful for search engine bots to understand what the image is and how it relates to your content. Additionally, it’s read aloud by screen readers which are made for visually impaired or blind people.
Alt text is added using the alt attribute in the HTML code of an image. However, Shopify lets you optimize alt texts without coding – there’s a dedicated section to do it in the “Product” section of your Shopify Admin dashboard.
You can see an example of how an alt text looks when the image doesn’t load below:
While adding alt texts on images is important for accessibility and SEO, not every visual needs it. Background, feature, and other design-focused images won’t bring much value to the reader, so alt text isn’t required. Meanwhile, the images within your content, such as graphs, should always include alt text.
Why is alt text important?
Alt text is a critical factor for a positive user experience and SEO. Here are all the reasons why creating alt texts is important:
Accessibility
Without alt texts, the part of your audience that is visually impaired or blind can’t have an accessible view of your content. This can hinder your brand reputation and potentially decrease traffic.
Naturally, this can also lead to lower conversion rates, as users who can’t understand the content may abandon your store.
Compliance
Alt texts are crucial for complying with the Americans with Disabilities Act (ADA) and other laws protecting disabled individuals. The ADA states that the lack of alternative text is considered an accessibility barrier. So, you should make your website accessible to prevent fines or legal action.
SEO
Search engines like Google, Bing, or Yahoo use alt texts to understand the context of images and their correlation with the content of the page. The better search engines comprehend your content, the more likely you are to rank higher.
Additionally, alt texts benefit image SEO. It helps images with keyword-optimized alt texts get higher in search engine image results, which can also drive traffic to your website.
Best practices for writing alt texts
Writing alt texts isn’t difficult, but there are a couple of useful tips to know. So, here are the best practices for writing effective alternative texts for images:
1. Include alt texts for non-decorative images
Make sure you differentiate which images need an alt text and which don’t. Think about the reader – do they need the screen reader to read aloud every single image? Skip adding alt text on decorative images that don’t add value to the page context so that screen readers don’t distract the user from what’s important.
For instance, let’s take a look at the ExpressVPN home page:
The background picture doesn’t add much value to the context – it’s purely a design choice. That’s why an alt text isn’t needed, and it could distract users with screen readers from the main content.
However, it’s still better to leave the alt attribute rather than none at all. This way, screen readers won’t choose to read the file name instead. It should look something like this:
<img src="example.jpg" alt=””>
The images that should include alt text are graphs, statistics, images with text, and other in-context visuals. Additionally, functionality icons like account, search, shopping cart, and others should also include alt text so users can navigate content with screen readers easier.
2. Be specific and descriptive
Alt texts need to be very descriptive but also specific depending on the content. It should describe the purpose of the used image with the reader in mind. Think of what’s useful for the reader to hear about the image.
For instance, let’s take a look at the picture below:

In some cases, describing it as a “funny shirt” can be more than enough. But if it’s a product you’re selling, it’s best to be more specific so people know what they’re buying. So, the alt text for this image could be “Black funny shirt for teenagers with the My mum says I’m cool text.”
Also, make sure you avoid including information that is already present in the text or phrases like “image of.” Instead, test your page with a screen reader to check if the alt texts make sense.
3. Include relevant keywords
Alt texts should include keywords that are relevant to the image context because they can help rank higher in search engine image results. For instance, once you enter “marketing strategies” into Google’s image search, you can find an image like the one below:
As you can see, it has the alt text attribute called “5 Marketing Strategies,” which is the main keyword. The reason the alt text doesn’t list all strategy types is that they’re already mentioned above the image.
Alt text examples
To get you acquainted with what effective alt texts look like, we found a few examples to show you. Here are some of them:
1. Space.com example
In one of Space.com articles, the feature image includes a descriptive alt text which you can see below:
The alt text is “a robotic lander stands on a barren grey surface against a black sky.” It’s below 125 characters and clearly describes what the image portrays.
The caption below the image complements the alt text instead of replicating it and is even more specific, including such details as the robotic lander’s title and image credit.
2. KitchenAid example
KitchenAid is a known brand for its phenomenal mixers, but the company has more than one brand that they own. They display it on their KitchenAid website:
If users can’t see the brand images loaded, all of the logos are replaced with alt text that includes brand names.
3. Apple store example
Apple stores use very specific and detailed alt texts for many of their images. However, one aspect we found interesting is that they also use short alt text for product color options.
This means the screen reader reads out model color names so the user can make an informed decision without seeing the colors.
