SEO-friendly image URL

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". 
Bad image URL
https://ik.imagekit.io/demo/DSC1234.jpg
SEO-friendly image URL
https://ik.imagekit.io/demo/eiffel-tower.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:
Javascript
React
Vue.js
// 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"
/>
