Title: Webflow CMS: Managing Alt Text for Dynamic Content
Introduction
Alternative text—commonly known as "alt text"—is a foundational element of accessible web design. It plays a crucial role in ensuring that users with visual impairments can interpret the content of images and non-text elements through screen readers and other assistive technologies. While managing alt text may seem straightforward for static images, it becomes more complex when dynamic content is introduced—especially within CMS-driven environments like Webflow.
If you’re building websites with Webflow CMS, dealing with dynamically generated content such as blog posts, product listings, or portfolio items, managing alt text appropriately is vital for accessibility and user experience. Not only does it support screen reader users, but it's also beneficial for SEO.
In this detailed guide, we’ll walk through how to effectively manage alt text for dynamic content in Webflow CMS, aligned with accessibility best practices, and how leveraging tools like allyWay can support your broader accessibility strategy.
Why Alt Text Matters for Accessibility and SEO
Alt text serves a dual purpose:
-
Accessibility
→ Enables users who rely on screen readers to understand visual content
→ Provides context when images fail to load
→ Supports compliance with important accessibility standards like WCAG 2.1 and the European EN 301 549 -
SEO
→ Helps search engines understand image content
→ Enhances image search visibility
→ Provides contextual relevance signals for on-page keywords
For websites using dynamic CMS systems like Webflow’s, managing alt text can’t be an afterthought—it must be part of the content architecture from the start.
Understanding Dynamic Content in Webflow CMS
Webflow CMS allows users to build powerful, flexible collections of dynamic content. From blog articles and case studies to product catalogs and team profiles, every content item stored in the CMS can be used across templates. The beauty of Webflow’s design is that you can build one template and scale it effortlessly across tens, hundreds, or thousands of items.
However, this raises a key accessibility question:
How do you ensure that each image rendered dynamically includes accurate, descriptive alt text?
Alt text must reflect the purpose and content of each individual image—and this gets complicated when images are populated automatically from a CMS collection without proper structure.
Challenges of Managing Alt Text in Webflow CMS
These are the most common challenges Webflow users face when working with dynamic content and alt text:
- ✓ Generic or missing alt text across CMS items
- ✓ Inconsistent content editor input in CMS form fields
- ✓ No clear workflow for assigning descriptive alt text dynamically
- ✓ Lack of fallback alt attribute for images without text
- ✓ No visual prompt or alt text preview for content editors
In Webflow, when an image is connected dynamically to a CMS collection field, you must explicitly connect the image's alt text to a corresponding CMS field. Failing to do this leads to missing alt attributes—a non-compliance red flag under WCAG success criterion 1.1.1 (“Non-text Content”).
Creating an Alt Text Strategy for Webflow CMS
To ensure accessibility of images across dynamic content, you need a clearly defined process. Let’s break it down into practical steps:
✓ Step 1: Create a Dedicated Alt Text Field in Your Collection
In the CMS Collection settings in Webflow:
- Go to the desired Collection (e.g., Blog Posts)
- Click + Add New Field
- Choose Plain Text
- Label it “Image Alt Text” or “Alt Description”
- Instruct your team to write meaningful alt descriptions
Pro tip: Make the character limit around 125 characters to encourage clarity and brevity.
✓ Step 2: Connect Alt Text Field to Image Element
In your Collection Page or Collection List:
- Add an Image Block connected to your CMS
- Under the image settings, click on Get Alt Text from
- Select the custom alt text field you created
Webflow will now programmatically assign the correct alt attribute for each image based on the content in the CMS.
✓ Step 3: Educate Content Editors on Writing Good Alt Text
Good alt text is specific, descriptive, and focuses on the image’s purpose, not just a literal description. For example:
- Poor: “Image of a man”
- Better: “CEO James Watkins presenting at the 2023 Berlin Accessibility Summit”
Encourage the following best practices among your content team:
- ✓ Don’t include “image of” or “photo of”
- ✓ Use plain language
- ✓ Avoid redundancy if the surrounding text already explains the image
- ✓ Capture meaning, not just appearance

Aligning with Accessibility Standards: WCAG, EN 301 549, and More
When managing alt text—and web accessibility more broadly—it’s crucial to understand how your efforts relate to major standards and regulations:
| Standard/ Regulation | Applies To | Relevance to Alt Text |
|---|---|---|
| WCAG 2.1 | Global (W3C guideline) | Requires text alternatives under 1.1.1 |
| EN 301 549 | Europe (public sector & ICT) | Alt text supports requirements for images |
| ADA (Title III) | United States (private sector) | Accessibility lawsuits often cite missing image text |
| EAA (European Accessibility Act) | EU-wide digital market | Enforces using accessible content formats |
It must be stressed: while alt text is a necessary part of accessibility, it alone does not make your website compliant.
Instead, it's part of a broader accessibility strategy—and tools like allyWay help organizations move closer to meaningful access for every user.
When to Use Empty Alt Text
In some cases, alt text should intentionally be left empty. According to WCAG:
→ Decorative images should use: alt=""
→ These are images that don’t convey content or meaning (e.g., background shapes, borders)
Webflow does not offer an explicit “empty alt” toggle, so it's up to content editors and designers to ensure that:
- Decorative images aren't added as “Image Blocks”
- Functional or informative images always include context-driven alt text

FAQs: Alt Text in Webflow CMS
Q1: Can I auto-generate alt text in Webflow?
No, Webflow does not offer built-in alt text generation. You must either write alt descriptions manually or use an external audit tool like allyWay to flag missing or inadequate alt tags.
Q2: What happens if I forget to add alt text to a dynamic image?
If you don’t bind an alt text field to the image, Webflow will not automatically include an alt attribute—which may result in accessibility failures under WCAG.
Q3: Is using the image filename as alt text acceptable?
Generally not. Image filenames often contain underscores, numbers, or irrelevant descriptors. They rarely convey meaningful content for screen reader users and may detract from perceived accessibility.
Q4: How do I handle alt text for multi-language sites in Webflow?
Create a multilingual CMS and provide alt text fields for each language variant. allyWay supports over 35 languages, making it easier to evaluate accessibility across localized content.
Q5: Will adding alt text improve SEO rankings?
Yes, to an extent. Descriptive alt text can help search engines understand context and improve image discoverability. However, SEO benefits strongly when aligned with user-focused accessibility intent.
