How to Write Alt Text That Works in 2026

You've just uploaded a great-looking photo, but the alt field says IMG_2034.jpg. On a live site, that tiny choice can turn a useful image into a dead end for screen-reader users and a missed signal for search engines. On a Wix site, it also means you've done the hard part, the photo is already there, but you haven't told anyone what it does.

Why Alt Text Matters for Your Small Business Website

The mistake usually happens fast. A bakery uploads a hero shot of sourdough loaves, a consultant adds a headshot to their about page, or a florist drops in a portfolio image from a recent wedding. The page looks polished, but the alt field gets the file name, or worse, a copy-paste of the surrounding paragraph. That wastes a good asset.

Alt text does two jobs at once. It gives screen-reader users a meaningful alternative to the image, and it helps search engines understand what the image is about, which supports image search visibility. ACQUIA's guidance makes the dual purpose clear. The accessibility standard behind it is WCAG, which requires non-text content to have a text alternative, and that approach is reflected in this alt text guide for accessibility and SEO.

For a small business, the cost is not abstract compliance. It is a booking page where the main banner cannot be interpreted properly, a product gallery where a customer cannot tell which item is which, or a service page where the image search result could have brought in a new visitor. On Wix and Wix Studio, that usually shows up in everyday content work, product photos that need clear labels, team headshots that should identify the person, and portfolio shots that need enough context to support the page. If you are also trying to keep SEO work tidy across visuals and page copy, optimized author SEO tools is a useful reference point for organising both without stuffing either one.

The working vocabulary that keeps the whole job sane

Use four labels when you sort images in Wix. Informative images carry real meaning, like product photos, team headshots, and portfolio shots. Decorative images are there for visual flavour only, such as a textured background or a repeated flourish. Linked images send people somewhere, and complex images contain data that needs more than a short line, such as charts or infographics.

That classification matters because different image types need different treatment. A bakery banner might need a short sentence. A decorative gradient probably needs nothing. A chart may need a brief alt text plus nearby text that explains the data clearly. For teams working through the editor, ACQUIA's guidance and Section 508's alternative text guidance are both useful checkpoints before you publish.

The Four Questions to Ask Before You Type a Single Word

A client opens the Wix editor to add alt text to a product gallery, then hits the same problem every time. The image is clear to them, but the field is not there to describe everything they can see. It is there to give the right information to the right user, in the right context. That is why the fastest way to avoid messy alt text is to ask four questions before you type anything at all.

A Wix site usually mixes hero banners, product shots, icons, logos, team photos, and gallery images. If you treat every image the same, you either overwrite useful context or add noise where nothing useful needs to be announced.

Ask what the image is doing

First, ask whether the image is informative. If a product photo shows the colour, shape, or style a customer needs to choose, it needs a description. If a team headshot sits beside a bio, it usually deserves a short, clean identification. If the image is a portfolio shot that proves a service outcome, the alt text should reflect that function, not just what is visible in the frame.

Then ask whether it is decorative. A patterned section divider, a blurred background, or a repeated flourish often adds nothing for a screen-reader user. In those cases, empty alt text is the right move, so assistive tech can skip it instead of announcing something unhelpful. That is not a shortcut, it is cleaner accessibility.

Practical rule: if removing the image would not make the page harder to understand, blank alt text is often the right call.

Linked and complex images need a different mindset

A linked image should tell users where the click goes or what action it triggers. A clickable logo might only need the business name if that is the link destination. A product card image should make the destination clear enough that the user knows what they will get when they activate it.

A complex image needs special handling. Charts, infographics, and some process diagrams cannot be summarised well in one sentence. In those cases, keep the alt text short and place a longer description nearby in the page content. That is the pattern used in practical accessibility guidance from the University of Iowa, North Carolina State University, and UK-facing guidance that stresses concise, context-driven writing, with alt text around 100 to 150 characters as a practical target for many images, and up to about 280 characters when the image needs more room to stay useful Design102.

For teams working through the editor, the visual content creation guide is also a useful reference point for deciding which images need real text and which ones do not.

Writing Alt Text That Actually Describes the Image

The best alt text sounds boring in the right way. It tells the truth quickly, uses the image's function in context, and stops before it starts repeating what the page already says. That's why weak alt text often feels like a summary of the file cabinet rather than the image itself.

Start with the one thing the user needs

For a product photo, write the feature that helps someone decide. A weak version is “IMG_2034.jpg”. A stronger version is “Blue ceramic mug with white handle” if colour is the deciding detail. If the product page already says “Blue ceramic mug”, you don't need to repeat the exact phrase again in the alt field unless the image adds something new, like a patterned glaze or a set of two.

For a team headshot, keep it direct. “Sarah Khan, founder of North Street Bakery” is usually enough if the bio already explains the role. For a location shot, write the place and the purpose. A portfolio image might become “Completed kitchen refurbishment in a Victorian terrace” if that's what the client needs to see.

A useful habit is to imagine the image removed. If the page loses information, the alt text should restore that missing piece. If the page doesn't lose anything, the image may be decorative, and alt text may be unnecessary.

Cut the filler, keep the function

There's no prize for beginning with “image of” or “picture of”. Screen readers already announce that the item is an image, and guidance from UK public-sector accessibility practice says to avoid that redundancy. The same applies to long, flowery descriptions that focus on every visible detail while missing the point. ReachLabs.ai's visual content creation guide is a useful reminder that visual assets work best when the message is clear before the design polish starts.

Alt text should help someone act, understand, or orient themselves. If it only describes decoration, it's probably too much.

A before-and-after rewrite often looks like this. “Team member smiling in office” becomes “Bookkeeper James Lee at his desk in the Manchester office” if the image supports trust and identification. “Sales chart on white background” becomes “Monthly revenue chart showing a steady upward trend” only if the trend is the point of the graphic. If the surrounding caption already explains the chart fully, UCL Press guidelines note that alt text may not be required when the main text or figure caption already does the job UCL Press alt text guidelines.

That's the useful trade-off. Describe the image enough to carry meaning, but don't turn alt text into a second paragraph. The sweet spot is usually a short sentence that someone can hear once and immediately understand.

Adding Alt Text in Wix and Wix Studio

Wix and Wix Studio both make alt text possible, but the field label isn't always the same across elements. On a simple image, you're usually looking for alt text, description, or an accessibility field inside the image settings. The exact menu changes by editor, but the job doesn't.

The cleanest workflow starts from the image itself. Click the image in the editor, open its settings, then look for the accessibility or SEO-related text field. In the classic Wix Editor, that's typically inside the image settings panel. In Wix Studio, the options are usually tucked inside the element inspector or the media settings. If you're unsure which workspace you're in, this Wix Studio editor guide helps separate the two.

For a single image, type the description directly into the field, then save. For a gallery, open each image one by one, because gallery items often carry their own metadata rather than inheriting a shared label. For a background image on a section, check whether the image is purely decorative. If the text on top already explains the banner, blank alt text is usually the cleaner choice.

What to do with icons, buttons, and linked elements

Icons need special care because they're often treated like decoration when they're really navigation. A search icon, social icon, or arrow button should describe the action or destination if the icon is the thing people click. If a text label sits beside it and already explains the action, the icon may not need extra wording.

The same logic applies to linked logos. A home link on the site header should usually identify the business name, because that's what the user needs to know. If you're editing an image-based button, think about what a screen-reader user hears when they tab to it. If the answer is vague, the alt text probably needs work.

Later in the page, the video below is useful if you want a visual walk-through of the editor flow rather than a written one.

The common Wix quirk is this. Decorative images are easy to leave with default text by accident, especially when you duplicate sections or reuse layouts. That's how noise creeps in. A quick pass through image settings after publishing saves you from screen readers announcing every background accent on the page.

Five Mistakes We See on Client Sites Every Week

On a real small business site, alt text usually goes wrong in the same few ways. The field gets filled because it's there, not because someone has decided what the image is doing on the page. Once you know the pattern, the fix is usually quick, especially in Wix or Wix Studio where you're often working through product shots, team headshots, portfolio images, and repeated layouts.

The five patterns to watch for

• Keyword stuffing. A line like “wedding florist London florist flowers florist bouquet” reads badly and helps nobody. Write the image's real purpose first, then include a relevant keyword only if it fits naturally.

• Being too vague. “Image” or “photo” tells the user nothing. Name the subject, the action, or the detail that matters.

• Skipping gallery images. One descriptive hero image and six blank thumbnails still leaves gaps. Every informative image in a gallery needs its own judgement call, especially on service pages and portfolio grids.

• Ignoring background images. Decorative section art can be blank, but if a background carries meaning, it should not be hidden from assistive tech.

• Forgetting form buttons. An icon-only submit button still needs a clear label so users know what happens when they activate it.

The biggest mistake we see is copy-paste duplication. If the paragraph above the image already says “Our handmade sourdough is baked fresh every morning in Camden”, do not repeat the same sentence in the alt field. A screen reader user hears the same point twice, which slows them down and adds nothing. Accessibility guidance from universities and platform teams says the same thing, keep alt text useful, not repetitive, and treat surrounding copy as part of the decision.

Another common failure is letting the file name pretend to be a description. IMG_2034.jpg is not alt text, and neither is a photographer credit, a campaign title, or a random page keyword. If the image matters, say what it shows. If it does not, mark it decorative and move on.

A quick audit helps here, especially on pages with lots of visual content. If you are checking design, SEO, and accessibility together, this Wix website audit checklist is a useful companion.

Testing, Auditing and the Tools Worth Using

Alt text only matters if it's present, readable, and not duplicated across a page. A quick audit catches the problems that sneak in during publishing, especially on image-heavy service pages and galleries. You don't need a large toolkit to do that well.

Start with the browser. Open Chrome DevTools, inspect a page, and search for images with missing alt attributes or obvious placeholders. That catches the basic gaps quickly. Then tab through the page with a screen reader or built-in accessibility tools on three key pages, usually the home page, a service page, and a contact or booking page.

A sitemap review helps if your site has lots of visual content. Look at the pages that carry product ranges, portfolios, case studies, or galleries, because those are the places where alt text gets skipped most often. If you want a broader quality check, this Wix website audit checklist is a handy companion when you're checking design, SEO, and accessibility together.

Free tools worth having open

Tool	What it checks	Best for
WAVE	Missing alt text, empty links, contrast issues	Fast visual review
axe DevTools	Accessibility errors in the browser	Spot checks while editing
Chrome DevTools	HTML markup, missing image attributes	Quick page-level inspection

Use the tool that matches the problem you're trying to catch. WAVE is handy when you want a broad view. axe DevTools is useful when you're checking a page that already feels mostly right. Chrome DevTools is the blunt instrument that helps you see whether the markup matches what you typed into Wix.

Best short habit: if time is tight, check the homepage hero, the top service page, and one gallery page first. Those usually expose the biggest alt text errors fastest.

Your Alt Text Checklist and Next Steps

Keep this checklist open while you edit. Start by classifying the image. Is it informative, decorative, linked, or complex? Then write one sentence that gives the user the most important part of the image. Cut repeated wording, file names, and filler like “image of”. Leave decorative images blank. Test the page with a screen reader or an accessibility audit tool before you publish.

For most images, around 100 to 150 characters is a practical working range, with longer descriptions reserved for complex visuals. Keep the wording concise, specific, and tied to what the image does on the page. Short alt text is usually the safer default, while decorative images can stay empty when they do not add meaning.

A good Wix site does not need every image to say more. It needs each image to say the right thing once. A product catalogue needs clear product names and useful details. A service portfolio needs enough context for a visitor to understand the work. Team headshots usually only need the person's name and role. If your homepage banners are still being sorted, a focused alt text pass before the next update is usually the quickest win.

Keep the standard simple. If an image helps someone choose, book, compare, or understand, describe that function first. If it is only there to fill space, leave it blank. That approach keeps small-business sites cleaner for screen reader users and easier to maintain inside Wix, especially when new photos and banners are added by different people over time.
