ImageKit helps you create SEO-friendly URLs dynamically

Image SEO starts with the file name. Google uses the URL path as well as the file name to understand your images.

For example, consider the following image of the Eiffel Tower:

The image URL should have "Eiffel Tower" instead of "DSC1234.jpg".

Dynamic SEO suffix (ik-seo)

When you cannot modify the file names of already stored images, ImageKit helps you create SEO-friendly URLs dynamically.

For example, let say you have the following image of the Eiffel Tower.

https://ik.imagekit.io/demo/DSC1234.jpg

Here, https://ik.imagekit.io/demo/ is your URL-endpoint.

You can dynamically use eiffel-tower.jpg as the file name using ik-seo parameter. For example:

https://ik.imagekit.io/demo/ik-seo/DSC1234/eiffel-tower.jpg

So the following URL: https://ik.imagekit.io/demo/ik-seo/DSC1234/eiffel-tower.jpg

will fetch the same image as: https://ik.imagekit.io/demo/DSC1234.jpg

Essentially

your-url-endpoint/old-file-name.extension

becomes:

your_url_endpoint/ik-seo/old-file-name/seo-friendly-file-name.extension

Accessing file that is stored in a nested folder

If your file is stored inside a nested folder e.g.

https://ik.imagekit.io/demo/path/of/folder/old-file-name.jpg

You can still dynamically add an SEO-friendly suffix like this:

https://ik.imagekit.io/demo/ik-seo/path/of/folder/old-file-name/seo-friendly-file-name.jpg

Examples

Let's say we have the following URL:

https://ik.imagekit.io/your_imagekit_id/default-image.jpg

We want to change the file name from default-image.jpg to seo-friendly-file-name.jpg

So the new URL becomes

https://ik.imagekit.io/your_imagekit_id/ik-seo/default-image/seo-friendly-file-name.jpg

Let's do this using the client-side SDKs:

// Without ik-seo
var imageURL = imagekit.url({
    path: "/default-image.jpg",
    urlEndpoint: "https://ik.imagekit.io/your_imagekit_id/",
    transformation: [{
        height: 300,
        width: 400
    }]
});
​
// With ik-seo
var imageURL = imagekit.url({
    path: "/default-image/seo-friendly-file-name.jpg",
    urlEndpoint: "https://ik.imagekit.io/your_imagekit_id/ik-seo",
    transformation: [{
        height: 300,
        width: 400
    }]
});

// Without ik-seo, urlEndpoint has been defined in parent IKContext 
<IKImage
  path="/default-image.jpg"
  transformation={[{
    height: 300,
    width: 400
  }]}
/>
  
// With ik-seo
<IKImage
  urlEndpoint="https://ik.imagekit.io/your_imagekit_id/ik-seo"
  path="/default-image/seo-friendly-file-name.jpg"
  transformation={[{
    height: 300,
    width: 400
  }]}
/>

// Without ik-seo, urlEndpoint has been defined globally 
<ik-image 
  path="/default-image.jpg"
  :transformation="[{height:300,width:400}]"
/>
​
​
// With ik-seo
<ik-image 
  path="/default-image/seo-friendly-file-name.jpg"
  :transformation="[{height:300,width:400}]"
  urlEndpoint="https://ik.imagekit.io/your_imagekit_id/ik-seo"
/>
