Don't Miss Out: Why Your Shopify Store's Image Alt Text is a Hidden SEO Goldmine
Hey everyone! I was just diving into a really insightful discussion over in the Shopify community forums that I knew I had to share with you. It touched on something many of us might overlook but has a huge impact on our store's visibility: image alt text. One of our community members, Jlcreasy, who builds an SEO app for Shopify, did some serious digging. They audited 591 product pages across 100 established Shopify stores and found some eye-opening stats.
The Shocking Truth About Shopify Image Alt Text
Jlcreasy's findings were pretty stark: a whopping 27% of product images had absolutely no alt text. And this wasn't just small, brand-new shops; these were established DTC brands! Another 8% used the product title as the alt text on every image, which, as we'll discuss, isn't much better. Only 9 out of 100 stores had alt text on every single image. That's a lot of missed opportunities, isn't it?
You might be thinking, "Does alt text really matter that much?" Absolutely! Google Image Search and the image results within normal search rely heavily on alt text to understand what an image shows. If it's missing, or too generic, your product photos are practically invisible to search engines. This isn't just about SEO, though; it's also vital for accessibility. Screen readers use alt text to describe images to visually impaired users, making your store inclusive.
Crafting Alt Text That Converts (and Ranks!)
So, what does good alt text look like? Another fantastic contribution to the thread came from adwaizer, who shared a brilliant checklist, especially for apparel and products with color variants:
- Be Descriptive and Specific: Don't just repeat the product title. Think about what the photo *shows*. For example, instead of "Crinkle Blouse," use "Crinkle Blouse in Navy, worn by a model, back view." This gives Google (and shoppers) context.
- Use Shopper-Facing Language: If your internal product code for sage is "SGE-02," your alt text should say "Sage," not the internal code. Match the language your customers use.
- Keep it Concise: Aim for around 125 characters. Screen readers read the entire alt text, so a long keyword-stuffed list is actually worse than nothing.
- Empty Alt for Decorative Images: If an image is purely decorative (like a spacer or a repeated brand badge that adds no information), use an empty alt attribute (
alt=""). This tells screen readers to skip it, preventing repetitive announcements.
How to Check Your Store's Alt Text (and Fix It!)
Ready to see where your store stands? Here's how to check and address any issues:
1. Quick Manual Check (for a few products):
Open any product page on your Shopify store. Right-click on the main product image and select "Inspect" (or "Inspect Element"). Look for the alt="" or a generic filename like alt="IMG_4023", it's missing or unhelpful. You can fix individual images directly in your Shopify admin under the image in the product editor.
2. Checking at Scale (for hundreds or thousands):
For larger catalogs, manual checks aren't practical. Jlcreasy mentioned their app, Shoptimal, which scans your catalog, identifies missing alt text, and helps you write and approve fixes. This can be a huge time-saver.
Another excellent tip from alaattincagil in the thread was to pull the /products/handle.json for each product. This shows you the alt text as it's saved in your admin. You can then compare this to what's rendered on the live page. Why? Because sometimes alt text is missing in the admin (a content problem), and sometimes it's filled in the admin but not rendered by an older or heavily customized theme (a theme problem). Knowing the difference helps you apply the right fix!
3. Verify Crawlability with URL Inspection:
As Jlcreasy and ahsandoesntcare pointed out, it's crucial to ensure your images aren't blocked by robots rules and appear in the rendered HTML. Use Google Search Console's URL Inspection tool on a product page. This will show you exactly how Google sees your page and if any images are being missed.
What to Expect: SEO Impact and Timing
So, you've gone through and fixed all your alt text – great job! But how long until you see results? This was a key question in the forum, and several experts weighed in.
- Patience is Key: Google needs time to recrawl and reindex your images. Mustafa_Ali, ahsandoesntcare, and alaattincagil all agreed that you'll typically see the first movement in Search Console's image traffic report gradually, usually around 4 to 8 weeks. A clearer trend might take 2 to 3 months.
- Where to Look: Head to Google Search Console, go to "Performance," and switch the "Search type" to "Image" (instead of the default "Web"). This is where you'll track impressions and clicks specific to your images.
- Compare Smartly: Don't just look at week-over-week data. As alaattincagil wisely suggested, compare against the same period year-on-year to account for seasonality.
- Alt Text Isn't the Only Signal: While alt text is powerful, it's part of a bigger picture. Google also uses computer vision, the surrounding page content (captions, titles, product copy), unique image filenames, and internal links to those pages to understand your images. Images placed on pages that already rank well can also boost image traffic.
Ultimately, investing in proper alt text is a no-brainer for any Shopify store owner. It improves your SEO, boosts your accessibility, and helps more potential customers find your amazing products through image searches. It might feel like a chore, especially with a large catalog, but the long-term benefits for your traffic and sales are absolutely worth it. Don't let those hidden opportunities pass you by!
