Most alt text guides give you rules. This one gives you examples — 60 of them, drawn from real site audits, organized by industry, with a bad version and a better version side by side. If you’ve been wondering what good alt text actually looks like for your type of site, scroll to your industry and steal what applies.
We’ve also added SEO context most example lists skip: why each fix matters for Google Search rankings (not just accessibility), what the ranking impact looked like in practice, and how to apply these at scale when you have hundreds or thousands of images.
Before the examples, a framework. Alt text serves two systems simultaneously — screen readers and search engine crawlers. What’s good for one is almost always good for the other, with one SEO-specific addition:
| Principle | Accessibility | SEO |
|---|---|---|
| Describe the image, not the page | ✅ Essential | ✅ Essential |
| Be specific (color, material, context) | ✅ Essential | ✅ Essential — specificity = long-tail keyword signal |
| Under ~125 characters | ✅ Screen readers truncate beyond this | ✅ Crawler efficiency |
| Don’t start with “Image of…” or “Photo of…” | ✅ Redundant — reader already announces “image” | ✅ Wastes the first few characters |
| Include keyword if it fits naturally | Neutral | ✅ SEO-specific addition — adds topical signal |
| Empty alt=”” for decorative images | ✅ Tells screen reader to skip | ✅ Avoids noise in the content signal |
Where these 60 examples come from: every pair below is pulled from real sites we audited between 2023 and 2025. Customer names are redacted; industries are accurate. The “bad” version is what was actually live when we found it. The “better” version is what we replaced it with — and in several cases, we show the ranking impact that followed.
E-commerce images have the highest SEO value per image — Google Shopping pulls product images from your markup, and Google Images drives meaningful commercial traffic for product searches. Missing or weak alt text here is the most expensive mistake on a per-image basis.

Impact observed: A 12,400-SKU outdoor apparel WooCommerce store had 78% of product images with missing or single-word alt text. After bulk rewrite using ImageSEO, Google Images impressions went from 48k/month to 187k/month in 8 weeks. No other changes were made.
Real estate images rank for property-type + location queries in Google Images. Specific location detail in the alt text (neighbourhood, architectural style, property type) drives the most relevant search traffic.

Camera default filenames (DSC_0421, IMG_4820) are the most common source of missing signal on photography sites. The alt text should replace that lost context with subject, location, and shooting condition — the terms clients actually search for.

Fashion images rank for very specific product queries — color, material, silhouette, and style period. Google Shopping pulls from product schema and alt text. The more specific the alt, the better the match to long-tail commercial queries.

Education and nonprofit sites are subject to WCAG accessibility requirements in many jurisdictions. Alt text is not optional — and getting it right also helps program and impact pages rank in image search, driving donor and student discovery.

|---|---|
alt="students" |

Not every image needs descriptive alt text. Decorative images — those that are purely visual, add no information, and are already explained by surrounding text — should have alt="" (an explicit empty attribute). This tells screen readers to skip the image. It tells Google: “this image carries no content signal.”
| Image type | Correct alt | Why |
|---|---|---|
| Gradient background blob | alt="" |
No information; decorative only |
| Section divider line | alt="" |
Structural element; no content |
| Icon next to labelled button | alt="" |
Button text already conveys the meaning |
| Abstract hero background image | alt="" |
Mood/aesthetic only; heading carries the message |
| Star icon in a rating display | alt="" |
The numeric rating and review text carry the signal |
The critical distinction: alt="" (empty attribute, explicitly set) is not the same as omitting the attribute entirely. An image with no alt attribute at all causes screen readers to announce the filename. alt="" tells the screen reader to skip silently. Always set it explicitly.
alt="best image seo wordpress plugin alt text optimization tool" is a spam signal. Google’s Penguin-era updates extended keyword stuffing detection to alt text. Write for humans first.alt="ceramic mug", Google treats them as duplicates and deprioritizes all of them. Every image needs a unique description.alt="Best image SEO guide for WordPress users in 2026" describes your article, not the screenshot you’re annotating. The alt must describe what’s in the picture.alt="" for decorative images.If your site has hundreds or thousands of images with missing or weak alt text, manual fixing isn’t practical. Your options:
wp_postmeta as _wp_attachment_image_alt. SQL updates are possible but risky — a mistake can corrupt your media library. Not recommended unless you have a tested backup and rollback plan.Almost. Technically there is no <alt> tag in HTML — there’s an alt attribute on the <img> element. “Alt tag” is colloquial shorthand for “alt attribute” and has been widely understood by both developers and SEOs for decades. Google processes both terms as the same concept.
Yes, in two ways. Directly: alt text is a primary signal for Google Image Search rankings. An image with a specific, relevant alt text ranks for queries that image without alt text never would. Indirectly: it contributes to overall page quality signals and WCAG accessibility compliance, which Google’s quality evaluators assess.
Every image needs an alt attribute. Content images (products, photos, diagrams, screenshots, infographics) should have descriptive alt text. Decorative images (background textures, dividers, icons next to labels) should have alt="" — an explicitly empty attribute, not a missing one.
Yes. In 2026, AI-generated alt text from vision models is excellent for most standard image types — product photos, landscapes, people, UI screenshots. The remaining gap is brand-specific context that the AI can’t know (your specific model name, your brand voice, your target keyword). The best workflow: AI generation to 90%, human review to add brand context where needed.
Under 125 characters. Screen readers truncate longer alt text at that threshold. Google processes the full text but shorter alt text is generally more precise and more useful — describe the key subject and context in one concise phrase, not a sentence.
Include your target keyword in the alt text if it fits naturally and describes something actually visible in the image. Do not force keywords in. alt="image seo wordpress plugin screenshot showing bulk alt text generation" — the keywords are there because the screenshot genuinely shows that. alt="image seo wordpress plugin image seo tool alt text" is stuffing and will hurt, not help.
