Image SEO Best Practices in Webflow

Choose the Right File Format

• JPEG/JPG: Best for photos; high quality with a reasonable file size.
• PNG: Use for graphics, logos, and images that require transparency.
• WebP: Modern format; smaller file sizes than JPEG/PNG while maintaining quality.
• SVG: Ideal for icons, logos, and vector graphics; scalable without losing quality.
• Tip: Webflow supports all of these formats. When possible, prefer WebP to improve page load speed.

‍

Compress images before uploading

Large images slow down your site and can hurt SEO. Use tools like:

• TinyPNG
• Squoosh
• ImageOptim

Goal: Whenever possible, images should be under 200 KB, without any noticeable loss of quality.

‍

Use descriptive file names

• Name your images with keywords relevant to your content.
• Avoid generic names like IMG_1234.jpg.

Example: red-running-shoes.jpg is better than shoes1.jpg.

SEO tip: Google uses file names to understand the content of an image.

‍

Add alt text for each image

• Alt text is crucial for SEO and accessibility:
• Clearly describe the image in plain language.
• Include keywords naturally (but don’t overdo it).

Example: Alt="Men's Red Running Shoes, Size 42, Lightweight and Breathable"

Tip: Webflow allows alt text for each image element in the Designer panel.

‍

Use Responsive Images

• Webflow automatically creates responsive image sets, which are the right size for each device:
• Faster loading on mobile and desktop
• Improved basic web metrics (speed, layout stability)

Check: Enable "Automatic" in the Designer image settings for optimal responsiveness.

‍

Leverage Lazy Loading

• Lazy loading delays the loading of images until the user scrolls to that section:
• Reduces initial page load time
• Improves SEO metrics (PageSpeed ​​Insights, Lighthouse)
• Webflow has lazy loading enabled for all images by default.

‍

Optimize image captions and surrounding text

• Google takes into account the context around images when ranking them.
• Add descriptive captions where appropriate.
• Ensure that surrounding content reinforces the theme of the image.

‍

Structured data for images (optional)

• For product or recipe images, consider schema markup.
• Helps Google understand images and display rich search results.
• Webflow allows custom code or plugins to add structured data.

‍

Test your page speed

After optimizing your images:

• Run Google PageSpeed ​​​​Insights
• Check for the recommendations “Display images in next-generation formats” or “Images of appropriate size”.
• Adjust your images or enable WebP export if necessary.
