Why Perfect Alt Text Matters

In 2025, alt text isn’t just about accessibility compliance—it’s a powerful tool that impacts your bottom line. If you’re new to alt text, start with understanding what alt text is and why it matters. Consider these statistics:

  • 71% of users with disabilities immediately leave websites with poor accessibility [1]
  • Image searches account for 32% of all Google searches [2]
  • Sites with optimized alt text see 47% higher conversion rates from organic traffic [3]
  • ADA lawsuits increased 320% in the past year, with average settlements of $35,000 [4] – learn how proper alt text prevents lawsuits while improving UX

The Triple Impact of Perfect Alt Text

Impact Area Poor Alt Text Perfect Alt Text Business Result
Accessibility Users can’t understand images Full context for all users +15% larger audience
SEO Performance Invisible to Google Images Ranks in image search +225% organic traffic – discover the hidden SEO goldmine in alt text
User Experience Broken images = confusion Context even when images fail -40% bounce rate

Real Cost of Bad Alt Text

Let’s calculate what poor alt text actually costs a typical e-commerce site with 1,000 product images. For e-commerce businesses, proper Shopify alt text automation can prevent these losses:

  • Lost SEO Traffic: 5,000 potential visitors/month × $2 value = $10,000/month
  • Accessibility Lawsuits: $35,000 average settlement + legal fees
  • Lost Disabled Customers: 15% of population × $50 AOV = $7,500/month
  • Total Annual Cost: $210,000+ in lost revenue and risk

The Anatomy of Perfect Alt Text

Perfect alt text follows a specific structure that balances description, context, and brevity:

The Perfect Alt Text Formula

[Subject] + [Action/State] + [Context] + [Important Details]

Breaking Down Each Component

  1. Subject (What/Who)
    • The main focus of the image
    • Specific, not generic
    • Example: “Golden retriever” not “dog”
  2. Action/State (Doing What)
    • What’s happening in the image
    • Present tense for actions
    • Example: “jumping through hoop”
  3. Context (Where/When)
    • Setting or environment
    • Relevant background info
    • Example: “at sunset on beach”
  4. Important Details (Why It Matters)
    • Distinguishing features
    • Relevant to page content
    • Example: “wearing service dog vest”

Length Guidelines

Alt Text Length Use Case Example
0 characters Decorative images only alt=””
5-15 words Simple images “Red coffee mug on wooden desk”
15-25 words Complex images “Team of developers collaborating around whiteboard with user flow diagrams in modern office”
25-50 words Detailed infographics Brief data summary + “Full details in text below”

Common Mistakes to Avoid

Based on analysis of 50,000 alt text examples, here are the most damaging mistakes [5]:

Mistake 1: Being Too Vague

Vague Specific Impact
“Product photo” “Blue ceramic coffee mug with company logo” +67% click-through
“Team photo” “Marketing team of 5 celebrating project launch” +45% engagement
“Chart” “Pie chart showing 60% mobile traffic share” +89% comprehension

Mistake 2: Over-Describing

❌ Too Much: “A rectangular photograph taken on a sunny day showing a yellow Labrador retriever dog with brown eyes and a red collar sitting on green grass next to a blue ball under a large oak tree with leaves rustling in the wind…”

✅ Just Right: “Yellow Labrador retriever sitting on grass with blue ball, wearing red collar”

Mistake 3: Keyword Stuffing

❌ Stuffed: “SEO services, best SEO services, affordable SEO services, SEO company, SEO agency”

✅ Natural: “SEO consultant reviewing website analytics report with client”

Mistake 4: Missing Context

✅ With Context: “Customer service representative smiling while helping client on phone”

Mistake 5: Redundant Phrases

Never Use:

  • “Image of…”
  • “Picture of…”
  • “Graphic of…”
  • “Photo showing…”

Screen readers already announce it’s an image!

Frequently Asked Questions

How long should alt text be?

Aim for 125 characters or less. Most screen readers cut off after this length. If you need more detail, provide a longer description elsewhere on the page.

Should I include “image of” in my alt text?

No. Screen readers already announce that it’s an image. Starting with “image of” or “picture of” is redundant and wastes valuable characters.

How do I handle complex infographics?

Provide a brief summary in the alt text (under 125 characters) and include a full text description either adjacent to the image or linked nearby.

Should alt text include keywords for SEO?

Include keywords only when they naturally fit the description. Write for humans first – good alt text naturally includes relevant keywords without forcing them. Learn more about writing SEO-friendly alt text that ranks.

What’s the difference between alt text and image captions?

Alt text describes the image for those who can’t see it. Captions provide additional context for all users. They serve different purposes and shouldn’t duplicate each other.
