Image Alt Text Guide for POD Sellers

How to Write Alt Text for Print-on-Demand Product Images

Alt text is a written alternative for an image. It helps communicate the image's useful content to shoppers who use screen readers and can also help search engines understand what the image shows.

Good product alt text is not a hidden list of keywords. It is a concise description of the image's purpose in the context of the product page.

A front shirt mockup, back design, sleeve close-up, lifestyle photograph, color chart, and size chart should not all use the same text. Each image communicates different information.

Example:

Black unisex T-shirt with a vintage Bigfoot barber illustration printed on the front

What Is Image Alt Text?

Alt text is the value placed inside an image element's alt attribute.

<img
    src="/images/bigfoot-barber-black-shirt.jpg"
    alt="Black T-shirt with a vintage Bigfoot barber illustration on the front"
>

Alt text can be used when:

• A shopper uses a screen reader.
• The image does not load.
• A search engine analyzes the page.
• A text-only interface presents the content.

Alt text should communicate the useful purpose of the image, not necessarily every visible detail.

Why Product Image Alt Text Matters

Accessibility

Shoppers who are blind or have low vision may rely on screen readers to understand product photographs, artwork placement, colors, diagrams, and other visual information.

Image loading failures

When an image cannot load, browsers may display the alt text in its place.

Search understanding

Search engines use alt text along with filenames, captions, page copy, headings, links, and structured data to understand an image.

Product clarity

Writing individual descriptions forces the seller to identify what each image contributes to the listing.

Write Alt Text for Accessibility First

The first audience for alt text is the person who cannot see the image. Search keywords should never make the text confusing, repetitive, or inaccurate.

Ask this question

The answer usually identifies what the alt text should communicate.

Example

A product page already states that the item is a black graphic T-shirt. The image shows the front artwork and its size.

Useful alt text:

Front view of black T-shirt showing the Bigfoot barber design centered on the chest

The text does not need to repeat every material, size, shipping, and care detail from the page.

Alt Text and Image SEO

Descriptive alt text can help Google understand the subject and purpose of an image. It works best as part of a complete image SEO system.

Image SEO also includes

• Descriptive image filenames
• Relevant nearby text
• Clear product titles and headings
• Fast-loading image files
• Mobile-friendly dimensions
• Product structured data
• High-quality product images
• Accurate captions when needed
• Internal links to the product page

Describe the Image in Context

The correct alt text depends on why the image appears on the page. The same photograph can need different text in different contexts.

Product page context

Black graphic T-shirt with a white flying saucer design printed across the chest

Article about print placement

Front T-shirt mockup showing a centered design positioned approximately three inches below the collar

Article about garment colors

Black, navy, and charcoal T-shirts displaying the same white graphic design

Alt text should support the purpose of the page rather than provide a generic description disconnected from the surrounding content.

Product Image Alt-Text Formula

Simple product image

White ceramic mug with a personalized black cat portrait

Graphic T-shirt

Black unisex T-shirt with a retro giant cat city illustration on the front

Back view

Back of black T-shirt showing nine small cryptid character illustrations

Sleeve detail

Close-up of white penny-farthing emblem printed on the right sleeve

Include only details that help someone understand the image and product.

How Long Should Alt Text Be?

Alt text should be concise, but there is no single mandatory character count that works for every image.

Many product images can be described in one sentence. Shopify recommends keeping alt text brief and suggests 125 characters or fewer as a practical target.

Too short

Shirt

Useful

Black T-shirt with a vintage Bigfoot barber illustration printed on the front

Too long

A paragraph describing every fold, shadow, background object, fabric wrinkle, camera angle, and decorative detail that does not affect the customer's understanding of the product.

Using Keywords Naturally in Alt Text

Product names and important product terms can appear naturally when they accurately describe the image.

Natural

Black Bigfoot barber graphic T-shirt shown from the front

Keyword stuffed

Bigfoot shirt Bigfoot T-shirt Sasquatch tee funny cryptid shirt vintage Bigfoot gift black graphic tee

Use these details when relevant

• Product type
• Design subject
• Garment color
• Front or back view
• Artwork placement
• Important material or finish
• Personalization
• Visible product feature

Do not add

• Unrelated search phrases
• Competitor names
• Every possible gift recipient
• Shipping promotions
• Sale language
• Invisible product details

Alt Text for Front Product Images

The main product image should identify the product and the visible design clearly.

Do not copy the full product description into the alt attribute.

Alt Text for Back Prints

Back images should explicitly identify that the back of the product is shown.

Examples

• Back of black T-shirt showing a large penny-farthing blueprint illustration
• Back view of black graphic tee with nine cryptid characters arranged in a grid
• Back of gray hoodie showing a large UFO abduction design below the hood
• Small white company logo printed below the rear collar of a black T-shirt

Avoid reusing the front-image alt text when the back image communicates different artwork.

Alt Text for Sleeve, Label, and Detail Images

Detail images usually exist to show a feature that is difficult to see in the primary mockup.

Sleeve examples

• Close-up of white penny-farthing emblem on the right sleeve
• Black cat symbol printed vertically on the left sleeve
• Industrial Mischief Division text printed on the left sleeve

Neck-label examples

• Interior neck label with circular Conspiracy Shirt Company logo
• Printed inner neck label showing brand name, size, and care information

Fabric and print-detail examples

• Close-up of white DTG ink printed on black cotton fabric
• Detailed view of distressed ink texture in the vintage front graphic
• Close-up showing the rib-knit collar and shoulder stitching

Alt Text for Lifestyle and Model Images

Lifestyle-image alt text should describe the product and any setting or pose that helps communicate fit, scale, or use.

Useful examples

• Model wearing a black Bigfoot barber graphic T-shirt outdoors
• Front view of model wearing a relaxed black cryptid graphic tee
• Person wearing a gray pullover hoodie with a UFO graphic while standing beside a wooded trail
• Black graphic T-shirt styled with jeans in a casual flat-lay arrangement

Avoid describing personal characteristics that are unrelated to the product or image purpose.

Alt Text for Product Color Images

When images exist to demonstrate different garment colors, identify the color and product clearly.

Examples

• Black Bigfoot barber graphic T-shirt shown from the front
• Heather navy graphic T-shirt with white cryptid artwork
• White graphic T-shirt with black folklore illustration
• Black, gray, and navy color options for the same UFO graphic tee

Do not describe a color that is not visible or available for the selected product.

Alt Text for Size Charts and Informational Graphics

A chart can contain too much information for a short alt description. Important measurements should also appear as real page text or in an accessible HTML table.

Short alt text

Unisex T-shirt size chart showing width and length measurements from small through 2XL

Better page implementation

• Use a short alt description for the chart image.
• Provide the measurements in an HTML table nearby.
• Include units such as inches or centimeters.
• Explain whether measurements are garment dimensions or body dimensions.
• Include measurement tolerance when available.

Do not place essential sizing information only inside an image.

Decorative Images Should Usually Use Empty Alt Text

Decorative images do not provide information needed to understand or use the page.

Examples may include:

• Background texture
• Decorative divider
• Corner illustration repeated beside a heading
• Visual flourish already described by nearby text
• Atmospheric background that adds no product information

Use an empty alt attribute:

<img
    src="/images/decorative-stars.png"
    alt=""
>

Do not omit the attribute entirely. An omitted attribute can cause some assistive technologies to announce the filename.

Alt Text for Linked Images and Image Buttons

When an image is the only content inside a link, its alt text should communicate the link's purpose.

Product card example

<a href="/products/bigfoot-barber-shirt">
    <img
        src="/images/bigfoot-barber-shirt.jpg"
        alt="View Bigfoot Barber graphic T-shirt"
    >
</a>

When the product name is already included as visible text inside the same link, the image may use empty alt text to avoid announcing the same link twice.

<a href="/products/bigfoot-barber-shirt">
    <img
        src="/images/bigfoot-barber-shirt.jpg"
        alt=""
    >
    <span>Bigfoot Barber Graphic T-Shirt</span>
</a>

Images Containing Important Text

Important product information should be available as real text whenever possible.

Images may contain:

• Size-chart measurements
• Material information
• Care instructions
• Shipping information
• Customization instructions
• Product comparison details

When the image text is essential and no equivalent is provided nearby, the alternative needs to communicate that information. Long or complex information is usually better placed in normal HTML content.

How to Add Alt Text to Etsy Listing Images

Etsy provides a text-alternative field for qualifying listing images. Each listing photo can have its own description.

Etsy alt-text recommendations

• Describe the specific listing image.
• Identify the product clearly.
• Include visible design details.
• Describe front, back, sleeve, or color views accurately.
• Avoid keyword lists.
• Do not repeat the exact same text for every image.
• Do not add information that is not visible.

How to Add Alt Text to Shopify Product Images

Shopify allows merchants to add and edit alt text for product media and theme images.

Shopify product-image workflow

1. Open the product in Shopify Admin.
2. Select the product image or media item.
3. Open the alt-text or media editing option.
4. Write a brief description of the image.
5. Save the change.
6. Repeat for each unique product image.

Shopify recommendations

• Keep the text brief and descriptive.
• Describe what is visually important.
• Use product terms naturally.
• Do not copy the same text into every image.
• Check imported Printify images after synchronization.
• Review variant images for correct colors.

Alt Text on a Custom PHP or Ecommerce Website

On a custom website, alt text should be escaped before it is placed in an HTML attribute.

<img
    src="<?= htmlspecialchars($imageUrl, ENT_QUOTES, 'UTF-8') ?>"
    alt="<?= htmlspecialchars($imageAlt, ENT_QUOTES, 'UTF-8') ?>"
    loading="lazy"
    decoding="async"
>

Store alt text separately

A useful image table can contain:

• Product ID
• Image URL
• Image position
• Garment color
• View type
• Alt text
• Sort order

This allows each front, back, sleeve, and detail image to use its own description.

Use Descriptive Image Filenames and Nearby Text

Alt text is only one image-search signal. Use filenames and nearby page content that support the same product meaning.

Weak filename

IMG_8472-final-v4.jpg

Better filename

bigfoot-barber-black-graphic-tshirt-front.jpg

Image SEO recommendations

• Use lowercase descriptive filenames.
• Separate words with hyphens.
• Place the image near relevant product text.
• Use a clear product H1.
• Write a useful product description.
• Add Product structured data.
• Resize images to appropriate dimensions.
• Compress website copies.

Write Unique Alt Text for Multiple Product Images

A complete POD listing may include several images. Describe what changes from one image to the next.

Product Image Alt-Text Examples

Common Product Alt-Text Mistakes

• Using only the product title: The text does not explain what is unique about the image.
• Copying the same text to every image: Front, back, detail, and lifestyle views become indistinguishable.
• Keyword stuffing: The text becomes a list of search phrases instead of a description.
• Starting every description with image of: The phrase usually adds no useful information.
• Describing invisible details: The text claims materials, features, or colors that cannot be confirmed from the image.
• Ignoring print placement: A back or sleeve image is described as a generic product photo.
• Omitting alt attributes: Screen readers may announce an unhelpful filename.
• Describing decorative images: Repeated visual flourishes create unnecessary screen-reader noise.
• Using alt text for long instructions: Complex content belongs in accessible page text.
• Placing essential information only in an image: Size and care information becomes inaccessible.
• Letting AI invent product details: Generated text may not match the real item.
• Writing for search engines instead of shoppers: Accessibility and clarity are lost.

Image Alt Text FAQ for POD Sellers

What is image alt text?

Alt text is a text alternative that communicates the purpose or important content of an image when the image cannot be seen. It can be read by screen readers and can also help search engines understand the image.

How long should product image alt text be?

Alt text should be as concise as possible while still communicating the useful visual information. Many product images can be described in one short sentence. Shopify recommends brief descriptions and notes that 125 characters or fewer is a useful target, although accuracy matters more than reaching an exact character count.

Should alt text include keywords?

Relevant product words can appear naturally when they accurately describe the image. Do not add repeated or unrelated keywords solely for search rankings.

Should every product image use the same alt text?

No. Each image should describe its own purpose, such as the front view, back artwork, sleeve print, color, size chart, close-up, or lifestyle setting.

Should decorative images have alt text?

Purely decorative images should usually use an empty alt attribute so screen readers can ignore them. The image should still include the alt attribute as alt="".

Should alt text begin with image of or picture of?

Usually no. Screen readers already identify the element as an image. Begin directly with the useful description unless the fact that it is a photograph, illustration, diagram, screenshot, or artwork is important.

What should a T-shirt product image alt text include?

Include the garment type, visible design subject, relevant garment color, and view or placement when those details help distinguish the image.

Should the product name appear in the alt text?

It can appear when it accurately and naturally identifies the product. Avoid copying an excessively long SEO product title into every image.

How should I write alt text for a back print?

Identify that the image shows the back of the garment and briefly describe the visible back artwork. Do not reuse the front-image description.

How should I write alt text for a size chart?

A short alt description can identify the chart, but important measurements should also be available as real text or an accessible HTML table near the image.

Does Etsy support image alt text?

Etsy allows qualifying sellers to add a text alternative to each listing image. The text should describe what is shown for buyers who cannot see the image.

Does Shopify support product image alt text?

Yes. Shopify allows alt text to be added or edited for product media and theme images through the Shopify administration and theme editor.

Can alt text improve Google Image visibility?

Descriptive alt text can help Google understand an image, especially when the image is placed near relevant page content and uses a descriptive filename. It does not guarantee rankings.

Can AI generate product image alt text?

Yes. The free AI Product Description Generator on this site can analyze an uploaded product image and generate both product description ideas and image alt text. The result should be reviewed for accuracy before publishing.
