Alt Tags for SEO: 30 Real Examples by Industry (2026 Guide)

By the ImageSEO Team. April 2026. ~10 min read.

Every alt text guide tells you “be descriptive” and “include keywords naturally”. Almost none of them show you what that actually looks like in your industry. That’s the problem this post fixes.

Below are 30 real alt tag examples, organized by industry, with both the bad version and the good version side by side. Steal whatever applies to your site.

The 4 rules these examples follow

Describe the image, not the page
Be specific (color, model, context)
Stay under ~125 characters
Don’t start with “Image of…” or “Picture of…”

For the full theory behind these rules, see our image SEO guide. Now to the examples.

What about decorative images?

Decorative images — gradient backgrounds, dividers, abstract shapes, icons that sit next to a label that already says the same thing — should have empty alt text:

Section divider line: alt=""
Background gradient blob: alt=""
Email icon next to “Email” label: alt=""
Decorative star next to a heading: alt=""

The empty alt="" tells screen readers “skip this — it’s not content”. Leaving the attribute off entirely is different — that makes the screen reader announce the file name, which is worse.

The 5 alt text mistakes you’re probably making

Stuffing keywords. alt="best image seo wordpress alt text seo plugin" hurts more than it helps. Google has been pattern-matching against keyword stuffing since 2012.
Reusing the same alt text. If 50 product photos have alt="ceramic mug", you’re confusing both Google and screen readers. Each image needs unique alt.
Starting with “Image of…”. Screen readers already announce that. Skip it.
Writing the page title in the alt. Alt text is about the image, not the page. Don’t summarize what the article is about.
Forgetting alt text exists. WordPress lets you upload thousands of images without ever filling in the alt field. Most sites we audit have 60–80% missing alt.

How to fix existing alt text in bulk

If you have a thousand images with no alt text, manually fixing them is a 30-hour job. Here are your options:

AI bulk generation: Tools like ImageSEO use vision models to generate descriptive alt text in bulk. Quality is now ~95% of what a human would write, in seconds per image instead of minutes.
Manual: WordPress Media Library lets you click each image and edit the alt field. Slow but free.
Database-level update: Risky — you can SQL-update the postmeta table directly, but if you mess it up you’ve corrupted your media library.

FAQ

Is “alt tag” the same as “alt text”?

Almost. Technically there’s no <alt> tag in HTML — there’s an alt attribute on the <img> tag. People use “alt tag” colloquially to mean “the alt attribute”, and Google understands both phrases.

Does alt text help SEO?

Yes, both directly (image search ranking) and indirectly (overall page quality signals). It’s also required for accessibility under WCAG 2.2 success criterion 1.1.1.

Should every image have alt text?

Every image needs an alt attribute. Content images should have descriptive alt. Decorative images should have alt="" (empty).

Can I use AI to generate alt text?

Yes, and in 2026 the quality is excellent — close to human-written for most images. The catch: AI doesn’t know your brand voice or target keywords. The best workflow is AI generation + human review.

What’s the best alt text length?

Under 125 characters. Long enough to be specific (color, context, subject), short enough that screen readers don’t truncate it.
