Image resizer links in Arc are pretty ugly. The only reference to an image filename is the Arc ID, like ABCDEFGHIJKLMNOPQRSTUVWXYZ.jpg. If clients want to improve the SEO scoring of their image links in Google, they need to be able to make that filename more realistic.
Like Canonical URLs do for gallery leaf pages, we want to introduce a string field SEO Filename. This field will be used by PageBuilder and others when generating Resizer V2 URLs by appending it before the asset key, like /resizer/v2/this-is-an-seo-filename-ABCDEFGHIJKLMNOPQRSTUVWXYZ.jpg.
SEO Filename must be formatted like a slug, where the only allowed characters are alphanumeric and dashes. It must be at or below 96 characters.
{
"_id": "ABCDEFGHIJKLMNOPQRSTUVWXYZ",
"additional_properties": {
...
},
"caption": "This is a caption.",
...
"seo_filename": "this-is-an-seo-filename",
"subtitle": "This is a subtitle.",
"type": "image",
"version": "0.10.9"
}
Long SEO Filenames could break the URL size limit
Yes, and that is why we are being conservative about the character limit we are imposing.
We considered using Slug for this purpose, but Slugs are "internal" by definition -- SEO Filenames are meant to be external.
Jimmy Schleicher of Photo Center will implement this and add to the schema if this proposal is accepted.
