In the competitive world of e-commerce, optimizing every element of your website is key to standing out in search results. One often overlooked yet powerful SEO tactic is the use of SEO Alt Tags Prestashop on your product and category images. Alt tags not only improve your store’s accessibility but also boost your search engine rankings by helping crawlers understand your images better.

If you run a PrestaShop store, mastering image alt tags is essential to enhance your mobile-first SEO strategy and drive more organic traffic.

What Are Alt Tags and Why Do They Matter?

Alt tags, or alternative text attributes, are descriptions added to images in your HTML code. These descriptions are displayed if an image fails to load and are read aloud by screen readers, making your website more accessible to visually impaired users.

From an SEO perspective, alt tags provide context about the image content to search engines like Google, which can’t “see” images but rely on text to understand them.

The Importance of SEO Alt Tags in a Mobile-First Era

With more than half of internet users browsing via smartphones, image optimization becomes critical. Mobile connections can sometimes cause images to load slowly or not at all. When this happens, alt tags serve as placeholders, giving users insight into what should appear, maintaining a smooth browsing experience.

Moreover, Google’s mobile-first indexing means your site’s mobile version—including images and their alt text—is what primarily determines your ranking. Properly optimized alt tags contribute significantly to your site’s relevance and usability on mobile devices.

How to Write Effective SEO Alt Tags in PrestaShop

Here are best practices for optimizing alt tags in your PrestaShop store:

1. Be Descriptive and Specific

Your alt tag should clearly describe what’s in the image. Instead of “shoe,” use “black leather running shoe with white sole.” This specificity helps search engines associate your image with relevant search queries.

2. Include Primary Keywords Naturally

Incorporate your primary keyword subtly into the alt tag when relevant. For example, if your product is a “women’s waterproof hiking boot,” the alt tag might be “women’s waterproof hiking boot with ankle support.” Avoid keyword stuffing, which can harm SEO.

3. Keep It Concise

Alt tags should be brief but informative—aim for 100 characters or less. Long, verbose descriptions can dilute the SEO value and make screen readers cumbersome.

4. Use Unique Alt Tags for Each Image

Avoid duplicating alt tags across multiple images. Each image should have its own unique description reflecting its content or context, especially for product variations.

5. Avoid Using “Image of” or “Picture of”

Screen readers already announce images, so phrases like “image of” or “picture of” are redundant and take up valuable space better used for descriptive text.

How to Add or Edit Alt Tags in PrestaShop

In PrestaShop’s back office, you can manage alt tags easily:

• Go to Catalog > Products

• Select a product and navigate to the Images tab

• For each image, there’s a field labeled “Legend” — this acts as your alt tag

• Improved Page Relevance: Alt tags provide context signals that help Google understand your page content better, improving rankings for related keywords.

• Enhanced Accessibility: Better accessibility can improve user experience and reduce bounce rates, indirectly boosting SEO.

• Mobile Performance: As alt tags appear during slow or failed image loads, they maintain content clarity and keep users engaged.
