Why Shopify Translations Miss Product Details

Your Shopify store is available in English, French, and German. Product titles and descriptions look translated, but a French shopper still sees English size instructions, untranslated product images, or technical specifications that use unfamiliar terminology.

This is a common Shopify product translation problem: translating the main description does not necessarily mean every piece of information on the product page is localized.

The solution is to audit product content by type, not just by page. Merchants need to check descriptions, variant labels, metafields, image text, alt text, and third-party app content separately. Each may use a different translation mechanism, and some require manual localization or additional tooling.

This guide explains where Shopify product translations commonly fall short, how to identify incomplete content, and how GLC Geolocation Redirect & Currency App can support a more consistent multilingual storefront.

Why Shopify Product Translations Remain Incomplete

Translation gaps usually happen because product information comes from several different content sources rather than one universal translation field.

Product descriptions are only one content layer

A Shopify product page may contain much more than its title and description.

Depending on the theme and installed apps, customers may also encounter:

• Product titles and descriptions.
• Variant names and option values.
• Technical specifications stored in metafields.
• Size guides and fit instructions.
• Product images containing written information.
• Image alt text.
• Shipping, warranty, and care instructions.
• Product review widgets and recommendation blocks.
• Custom theme sections and app-generated labels.

These elements are not necessarily stored or translated in the same way. Some are Shopify-native resources, while others come from theme settings, metafields, media assets, or external applications.

A translation workflow that covers titles and descriptions may therefore leave important buying information untouched.

Not every content type supports the same translation workflow

Shopify provides translation capabilities through its native localization tools and Translations API, but coverage depends on the underlying resource.

According to the Shopify Translate & Adapt documentation, certain content types cannot be translated directly through the app, including product images, tags, and third-party content that is not exposed as a supported translatable resource or locale file.

This does not mean that these elements can never be localized. For example, Shopify supports selecting different image assets for languages in applicable theme contexts.

The important distinction is that replacing a localized asset and automatically translating a text field are different operations.

Updates can create new translation gaps

Product content changes continuously. Merchants add variants, update specifications, replace images, and revise descriptions after the initial translation project is completed.

Depending on the translation workflow and settings, those updates may not automatically appear in every language.

Shopify's automatic translation documentation describes both manual translation actions and Auto-sync availability, which varies by store eligibility and configuration.

As a result, translation completeness is an ongoing maintenance task rather than a one-time setup.

Audit Every Product Detail Before Translating Again

A structured audit helps merchants identify which fields are missing translations before spending time retranslating content that already works.

Start with a product content inventory

Choose several products that represent different catalog structures, ideally including a bestseller, a variant-heavy product, and an item with technical specifications.

For each product, record where shoppers encounter information and how that information is maintained.

This audit distinguishes missing translations from content that was translated incorrectly or displayed through the wrong storefront configuration.

Separate missing, outdated, and incorrect translations

Not every translation problem requires the same solution.

• Missing: No translation exists for the field.
• Outdated: The source content changed, but the translated version did not.
• Incorrect: The translation exists but changes the intended meaning.
• Display mismatch: A translation exists, but the storefront displays another language.
• Unsupported content: The element requires a separate localization workflow.

For example, a translated washing instruction that contains an incorrect temperature is a content accuracy problem. An English washing instruction appearing on a French page is a missing translation or display problem.

Keeping these categories separate makes troubleshooting more efficient.

Review the storefront, not only the translation editor

A translation may appear complete inside an app while the live storefront still displays mixed-language content.

Preview the correct market and language combination, then inspect the actual product page on both desktop and mobile.

Focus on the information customers need before purchasing: specifications, variant choices, sizing, shipping details, and usage instructions.

Why Product Specifications Need Extra Translation Review

Technical product information often requires greater precision than marketing copy because small changes in meaning can affect purchasing decisions.

Keep measurements and technical values accurate

Consider a store selling rechargeable desk lamps in multiple markets.

Its product details might include:

• Input: 5V/2A.
• Battery capacity: 2,000 mAh.
• Charging time: approximately 3 hours.
• Dimensions: 24 × 12 × 8 cm.
• Material: aluminum alloy.

These specifications communicate factual product characteristics. A translation should preserve the underlying values rather than rewriting them for stylistic variety.

Some terms may require localization, but product specifications should remain consistent with the manufacturer's actual documentation.

Be especially careful with decimal separators, dimensions, electrical ratings, and product safety instructions.

Do not translate every technical term literally

Not all technical terms have a single natural equivalent across markets.

For example, a store selling mechanical keyboards may use terms such as "hot-swappable," "linear switch," and "actuation force."

Some markets commonly use English terminology for these features, while others prefer localized explanations.

Before translating a large catalog, identify the terminology customers in each target market expect to see.

This is particularly important for electronics, equipment, automotive accessories, and other specification-heavy products.

Keep variant terminology consistent

A product might use "Graphite" as a color name in its description but "Dark Gray" in its translated variant selector.

Both terms may be understandable individually, yet inconsistent terminology makes it harder for shoppers to confirm that they are selecting the intended item.

Create preferred translations for recurring option names, materials, fit descriptions, and other customer-facing attributes.

Use those terms consistently across descriptions, selectors, size guides, and related products.

Product Images and Alt Text Need Separate Attention

Images can carry important purchasing information, but translating surrounding HTML text does not necessarily localize the information inside those images.

Embedded image text is not ordinary product copy

A product image may contain labels, size measurements, ingredient explanations, instructions, or promotional messages.

For example, a blender product image might display:

• Three blending modes.
• Capacity information.
• Cleaning instructions.
• Safety warnings.

If these details are embedded directly into the image, translating the product description will not automatically replace the visible text in the image.

Merchants may need to produce localized image versions or use a translation solution with explicitly supported image-text functionality.

Shopify also documents workflows for localizing media assets through Translate & Adapt in supported theme contexts.

Image alt text is a separate localization field

Alt text describes an image for accessibility and other contexts where the image cannot be viewed.

A multilingual store should review whether this description is available in the appropriate language.

For example:

English: "Black adjustable desk lamp with a round base."

French: "Lampe de bureau noire réglable avec base ronde."

The translated description should accurately describe the same image. Avoid adding unrelated keywords or claims that are not visible.

Because image alt text is not the same as text embedded inside an image, both require separate checks.

Prioritize images that affect purchase decisions

Not every product image needs extensive language-specific customization.

A plain product photograph may work across several markets without modification, while a sizing infographic or instruction diagram may contain information that customers must understand accurately.

Prioritize:

1. Size and measurement graphics.
2. Safety and usage instructions.
3. Technical feature explanations.
4. Product comparison charts.
5. Warranty or service information.

This keeps localization effort focused on content with genuine customer value.

Why Third-Party App Content Stays Untranslated

Product pages frequently include information generated outside Shopify's standard product fields, making translation coverage dependent on each integration.

Some apps expose content through Shopify translation resources

Certain third-party apps store or expose translatable content through Shopify-supported resources or storefront locale files.

In these situations, compatible translation tools may be able to manage the text through Shopify's translation infrastructure.

Other apps generate content dynamically or use their own translation settings.

According to Shopify's Translate & Adapt documentation, third-party content that is not available as a supported translatable resource or storefront locale file cannot be translated through that native workflow.

Product widgets may contain multiple language sources

Consider a product page containing a size chart, review widget, and delivery message.

The main product description may be translated correctly while:

• The size chart uses English column headings.
• The review widget retains English interface labels.
• The delivery message uses the store's default language.
• The recommendation block displays untranslated product information.

These may represent separate translation problems, even though they appear together on one page.

For each widget, identify whether it uses Shopify translations, app-specific language settings, or another supported localization method.

Distinguish interface labels from user-generated content

A product review widget may contain interface labels such as "Write a review" alongside customer-submitted review text.

Those are different types of content.

Translating the widget interface does not necessarily translate historical customer reviews. Conversely, displaying a translated review does not prove that every interface element is localized.

Check both where relevant, and avoid claiming that all third-party content is automatically covered without testing the specific integration.

How GLC Helps Manage Shopify Product Translations

GLC Geolocation Redirect & Currency App combines AI translation with localization tools that help merchants manage multilingual shopping experiences.

GLC's current Shopify App Store listing includes AI translation for pages, products, images, image alt text, and third-party app content, along with a built-in glossary for terminology consistency.

These capabilities are relevant to stores that want to reduce translation gaps beyond basic product titles and descriptions.

Use AI translation as the first content pass

For stores with many products, translating every supported field manually can require substantial effort.

GLC's AI translation features can provide a starting point for localizing eligible product information across multiple languages.

A practical workflow is to identify the target languages, review the content types available in the app, and apply translation to the relevant resources.

After translation, inspect the localized storefront rather than assuming that every embedded element has been updated.

Image handling and third-party app content should be tested against the specific features and integrations currently supported by the store's configuration.

Use the glossary to protect important terminology

GLC lists a built-in glossary that helps merchants control key terms during translation.

This is useful when a catalog contains terminology that should remain unchanged or follow a preferred translated form.

Examples include:

For example, a merchant selling wireless charging accessories may need to preserve model codes while standardizing localized descriptions of charging speed, connector types, and compatibility.

The glossary supports consistency, but merchants should still review technical translations for accuracy.

Check localized content alongside language selection

GLC also provides country, language, and currency selection tools, including geolocation-based recommendations and redirects.

These features help shoppers reach the appropriate storefront experience, but language routing and translation completeness solve different problems.

A visitor may reach the correct French-language storefront while still encountering an untranslated specification table.

Therefore, test the selected storefront language and inspect the product content independently.

Build a Repeatable Shopify Translation Workflow

A reliable translation process combines content coverage, terminology control, storefront testing, and regular reviews after product updates.

Step 1: Prioritize products by translation risk

Start with products where missing or incorrect information could materially affect customer decisions.

Useful prioritization factors include:

• High traffic from target international markets.
• Products with complex specifications.
• Items with multiple size or compatibility options.
• Products containing text-heavy images.
• Products with extensive metafields or app-generated content.

For example, an electronics store may prioritize product compatibility information, while a furniture store may prioritize dimensions, assembly instructions, and material specifications.

Step 2: Create an approved terminology list

Prepare a compact reference list before generating large volumes of translations.

Include brand names, product identifiers, technical descriptions, recurring attributes, and terms that must remain consistent across multiple pages.

Use this list when configuring the GLC glossary and reviewing translated content.

Do not assume one translated term is appropriate for every market that uses the same language. Regional expectations can differ.

Step 3: Translate supported product resources

Apply translation to eligible product titles, descriptions, and other supported fields.

Then review fields that may require separate handling:

• Product-specific metafields.
• Text embedded in product images.
• Image alt text.
• Custom theme sections.
• Third-party app widgets.

For unsupported or unclear cases, check the current documentation for the relevant translation tool or third-party application.

Step 4: Review technical and high-risk details manually

AI-generated translation should not be the final verification step for information where accuracy is important.

Assign additional review to:

• Safety instructions.
• Electrical specifications.
• Size and fit measurements.
• Ingredients and material disclosures.
• Compatibility requirements.
• Warranty and return conditions.

Compare the translation with the approved source content and ensure that measurements, qualifications, and limitations remain intact.

Step 5: Verify the live storefront in each language

Open representative product pages using the intended language and market settings.

Inspect the product title, specifications, variant selectors, image descriptions, related widgets, and the surrounding purchase interface.

If a translated field exists but does not appear correctly, troubleshoot the display or resource integration before translating it again.

Shopify Product Translation QA Checklist

A simple testing matrix helps merchants identify which content types require correction or additional localization work.

Record problems by content source and severity. Missing size guidance may be more urgent than an untranslated decorative label.

Test desktop and mobile separately

Responsive themes may display different content blocks or widget layouts on mobile.

A translated specification table that looks correct on desktop might become difficult to read on a small screen. A mobile-specific section may also use a different content source.

Check that translated text remains readable and does not overlap buttons, product options, or important shopping information.

Recheck translations after catalog changes

Add translation QA to the product publishing process.

Whenever merchants update a product, identify whether they changed:

• Customer-facing copy.
• Variant labels.
• Metafield values.
• Images with embedded text.
• Technical specifications.
• Content generated by installed apps.

Then confirm that the relevant localized versions have been updated through the configured translation workflow.

For stores using Shopify Translate & Adapt, review the current automatic translation and Auto-sync settings rather than assuming every content change is synchronized immediately.

How to Measure Translation Completeness

Translation quality becomes easier to manage when teams measure the coverage of important fields instead of relying on whether a page appears mostly translated.

Track coverage by required content fields

A simple translation completeness metric can be calculated as:

Translation coverage = (Required fields verified in the target language / Total required fields audited) × 100

For example, if a product has 20 required customer-facing fields and 17 have been checked and confirmed in the target language, its verified coverage is 85%.

This is an illustrative internal QA metric, not a Shopify or GLC benchmark.

A high coverage score does not prove that the translations are accurate, so teams should track correctness separately.

Prioritize errors by customer impact

Not all translation issues deserve equal priority.

Classify issues into three practical categories:

• High priority: Incorrect specifications, missing safety information, wrong sizing instructions, or misleading compatibility details.
• Medium priority: Untranslated variant labels, incomplete feature explanations, or important widget instructions.
• Lower priority: Minor wording inconsistencies in decorative or nonessential content.

This framework helps small localization teams decide what to fix first without delaying every product launch over minor language differences.

Assign ownership for future updates

Translation maintenance becomes more reliable when responsibility is clear.

Content teams can maintain terminology and product copy, product managers can verify technical details, and storefront administrators can investigate theme or third-party integration problems.

Document which team owns each recurring issue so that new translations are reviewed before the same inconsistency appears across multiple product pages.

Final Thoughts

Shopify product translation problems often come from incomplete content coverage rather than a failure to translate the main product description. Product specifications, metafields, image text, alt text, and third-party widgets may require different localization workflows. Merchants should audit these elements separately, prioritize information that affects purchasing decisions, and verify translated content on the live storefront. GLC's AI translation and glossary capabilities can help maintain more consistent multilingual product information, while manual review remains important for accuracy and unsupported content.

FAQ

Why are some Shopify product details still in English after translation?

Those details may be stored in metafields, images, theme settings, or third-party apps that use different translation mechanisms. Check the content source and its supported localization workflow.

Can Shopify automatically translate text inside product images?

Shopify Translate & Adapt does not directly translate embedded image text. Merchants can use localized media assets in supported contexts or evaluate tools that explicitly support image translation.

Can GLC translate Shopify image alt text and third-party app content?

GLC currently lists image alt text and third-party app content among its AI translation capabilities. Merchants should test the relevant media and integrations to confirm coverage for their specific storefront.
