Image SEO

Fill missing image alt and title attributes with controlled templates so images stay more descriptive without manual cleanup on every page.

Overview

Image SEO fills in missing image attributes using templates.

Admin path: Airygen SEO -> Settings -> Image SEO

The important word is missing. This module is designed to help empty fields, not to overwrite the work you already entered by hand.

Settings

The page is divided into Add missing alt attributes, Add missing title attributes, and Template settings.

Add missing alt attributes

Use this section when images often ship without alt text.

  • Add missing alt attributes turns automatic alt generation on or off.
  • ALT attribute template defines the fallback text used for missing alt values.
  • The helper text explains that this is a runtime-only change, so stored post content is not rewritten.

Add missing title attributes

Use this section when missing title attributes are part of your workflow.

  • Add missing title attributes turns automatic title generation on or off.
  • TITLE attribute template defines the fallback text used for missing title values.
  • This is also a runtime-only change and does not rewrite stored content.

Template settings

Use this section to define the shared values used by both templates.

  • Separator is inserted when you use %separator%.
  • Custom token 1, Custom token 2, and Custom token 3 let you store reusable text.
  • Available tokens include values such as post title, image file name, Media Library title, counter, focus keyphrase, random long-tail keyphrase, separator, and the custom tokens.

How to Use

  1. Open Airygen SEO -> Settings -> Image SEO.
  2. Turn on Add missing alt attributes if empty alt fields are the main issue on your site.
  3. Enter an ALT attribute template that produces descriptive text instead of keyword stuffing.
  4. Turn on Add missing title attributes only if your site also needs fallback title attributes.
  5. Enter a TITLE attribute template, then set Separator and any Custom token values you want both templates to share.
  6. Save the module and open a page that contains images with missing attributes to verify the result.

Verify these items after saving:

  • Existing hand-written alt text is still untouched.
  • The generated text sounds natural when applied to real content.
  • The templates do not create repetitive or spammy wording.
  • You understand that the module changes output at runtime and does not rewrite stored content.

SEO Benefits

Better image attributes improve accessibility and add clearer context around media. They also help large sites reduce the number of empty image fields without editing every post manually.

User Cases

Sites with large older media libraries

Before: Hundreds of older posts contain images with missing alt text, and fixing them one by one is unrealistic.

After: Image SEO fills only the missing fields with template-based text, which improves baseline coverage quickly.

Editorial teams that reuse the same image patterns

Before: Repeated media uploads create inconsistent image titles and empty fields across many posts.

After: The team creates reusable templates so output stays more consistent without changing the stored Media Library content.

FAQ

Does this overwrite alt text I already wrote manually?

No. It is designed to fill only missing attributes.

Does this update the Media Library record itself?

No. The UI says the change is runtime-only, so the stored content stays the same.

Should I include keywords in every template?

No. The template should describe the image naturally. Use keywords only when they fit the image and page context.
