Introduction
In the competitive world of eCommerce SEO services, every optimization technique matters. One often-overlooked yet crucial element of on-page SEO is the image alt tag. eCommerce SEO experts use image alt tags to enhance website accessibility, improve search engine rankings, and boost user experience. But why are these simple text descriptions so important?
This blog delves into the significance of image alt tags, their role in SEO, and how eCommerce businesses can leverage them for maximum impact.
What Are Image Alt Tags?
An image alt tag (alternative text) is an HTML attribute that describes the content of an image on a webpage. These descriptions help search engines and visually impaired users understand what an image represents.
Example of an Alt Tag in HTML:
<img src="product-image.jpg" alt="Red leather handbag with gold chain strap" />
Here, the alt tag describes the image in a way that provides context for users and search engines.

The Importance of Image Alt Tags in eCommerce SEO Services
1. Improves Search Engine Rankings
Search engines like Google cannot “see” images the way humans do. Instead, they rely on alt tags to understand an image’s relevance. eCommerce SEO experts optimize alt tags with target keywords to help product images rank in Google Images and increase organic traffic.
2. Enhances User Accessibility
A significant percentage of internet users rely on screen readers due to visual impairments. Alt tags ensure that visually impaired customers can access image descriptions, improving user experience and compliance with accessibility guidelines such as WCAG (Web Content Accessibility Guidelines).
3. Boosts Image Search Visibility
Many shoppers use Google Image Search when looking for specific products. By optimizing image alt tags with descriptive keywords, eCommerce websites increase their chances of appearing in Google Image results, attracting more potential customers.
4. Reduces Bounce Rate and Enhances User Experience
When images fail to load due to slow internet connections, alt text provides a textual description. This ensures that users still understand the product or information, reducing frustration and bounce rates.
5. Increases Conversion Rates
Clear and optimized alt tags improve the shopping experience, making it easier for customers to find products through organic search. This leads to better engagement and higher conversion rates.

Best Practices for Writing Effective Image Alt Tags
To maximize the benefits of alt tags, eCommerce SEO experts follow these best practices:
1. Be Descriptive and Specific
Instead of writing vague alt text, describe the product clearly.
Bad Example:
<img src="shoes.jpg" alt="shoes" />
Good Example:
<img src="nike-running-shoes.jpg" alt="Black Nike running shoes with white soles, lightweight and breathable" />
2. Use Keywords Naturally
Include relevant keywords without keyword stuffing.
Bad Example:
<img src="bag.jpg" alt="Leather handbag, designer handbag, best handbag, stylish handbag, brown handbag" />
Good Example:
<img src="brown-leather-handbag.jpg" alt="Brown leather handbag with gold buckle and adjustable strap" />
3. Avoid Redundant Phrases
Do not include unnecessary words like “image of” or “picture of.” Search engines already recognize it as an image.
4. Keep Alt Tags Concise
Google recommends keeping alt text under 125 characters to ensure clarity and effectiveness.
5. Write for Users First
While SEO is important, ensure alt text makes sense to human readers, especially those using screen readers.
Common Mistakes to Avoid with Alt Tags
Even seasoned SEO experts sometimes make mistakes when writing alt tags. Here are the most common pitfalls:
1. Leaving Alt Tags Blank
If an image is crucial (e.g., a product photo), leaving the alt tag blank is a missed SEO opportunity.
2. Keyword Stuffing
Overloading alt tags with keywords can make them unreadable and may lead to Google penalties.
3. Using the Same Alt Text for Multiple Images
Each image should have a unique alt tag to avoid duplication and improve clarity.
4. Adding Alt Text to Decorative Images
Not all images need alt text. If an image is purely decorative, it’s better to leave the alt attribute empty (alt="") rather than adding unnecessary descriptions.
How to Audit and Optimize Alt Tags for eCommerce SEO
If you already have an eCommerce website with many images, conducting an alt tag audit can help improve SEO. Here’s how:
Step 1: Use SEO Tools
Use tools like Google Search Console, Screaming Frog, or Ahrefs to find missing or duplicate alt tags.
Step 2: Prioritize High-Traffic Pages
Start by optimizing alt tags on product pages, category pages, and blog posts that already receive significant traffic.
Step 3: Implement SEO Best Practices
Rewrite poorly optimized alt tags using the best practices mentioned earlier.
Step 4: Test Image Search Performance
Check if product images start appearing in Google Image Search and track improvements using Google Analytics.
The Future of Alt Tags in eCommerce SEO Services
With advancements in AI and machine learning, search engines are improving their ability to recognize images. However, alt tags remain essential for accessibility, SEO, and user experience.
Emerging trends in image search optimization include:
- AI-powered image recognition: Google Lens and Pinterest Lens are changing how users search for products visually.
- Voice search optimization: Descriptive alt text can improve voice search results for product-related queries.
- Structured data and schema markup: Adding schema markup for images enhances search visibility.
