I am trying to create some JSON-LD structured data for a list of products on an ecom-site but I am getting an error when using Google's Structured Data Testing Tool.
So far, I have this:
{
"@context": "http://schema.org",
"@type": "OfferCatalog",
"name": "Fresh Fruit",
"itemListElement": [
{
"@type": "ListItem",
"position": 1,
"item":
{
"@type": "Offer",
"price": "1.20",
"priceCurrency": "GBP",
"availability": "http://schema.org/InStock",
"url": "http://example.com/green-apples/",
"itemOffered": {
"@type": "Product",
"name": "Green Apples",
"url": "http://example.com/green-apples/"
}
}
}
]
}
Mostly it validates, but the Google tool throws the following error:
All values provided for url must point to the same page.
The error highlights line 11 ("@type": "Offer",).
The URL fields seem to be clashing with the (This has been shown to be a red-herring, in the comments below)@context declaration, because if I change the context to either a non-url string or http://example.com, it validates (although, this obviously causes its own issues).
What am I missing here? It feels like something blindingly obvious.
It is surely an error in the validator. I checked with the examples google provided: https://developers.google.com/search/docs/guides/mark-up-listings . If you click on the 2nd example you will see that it has the same error.
The error is shown even if you use 1 item:
{
"@context": "http://schema.org",
"@type": "ItemList",
"itemListElement": [
{
"@type": "ListItem",
"position": 1,
"item": {
"@type": "Recipe",
"url": "http://example.com/desserts/pies/#apple-pie",
"name": "Apple Pie",
"image": "https://example.com/300px-Apple_pie.jpg",
"author": {
"@type": "Person",
"name": "Carol Smith"
},
"datePublished": "2009-11-05"
}
}
]
}
I think it is connected with pushing of accelerated mobile pages and its structured data.
Please check my thoughts here: All values provided for URL must point to the same page. My guess was about the problem in Google’s SDTT
So, to fix the problem with your structure data, please use the correct version of ItemList (there are Separately and Combined marked up ItemLists, please check here):
If your items are on the same page, please use the version with items inside, the Combined one.
Otherwise, if you point to different pages inside and your items are not on one page, please DON’T put item element with type and other description inside, the Separately marked up one.
I think the issues occurs when we mix two list types i.e Summary page + multiple full details pages and A single, all-in-one-page list.
Google stated on page - https://developers.google.com/search/docs/guides/mark-up-listings
- If this is a summary page, the ListItem should include only the type, position, and url properties.
- If this is an all-in-one-page list, the ListItem should include all the additional schema.org properties for the data type that it describes (for example, Recipe or Course objects).
But Google should consider eCommerce category's product listing where people display numbers of product with more than 3 properties on summery page and these are obvious for eCommerce, like price and image are 2 important item on product listing page except the 3 listed above.
So we need to raise this issue with Google to address the concern.
Now it's 2018.
Answer by Yash Pal above is close, but not quite right.
This is not an error from Google validator tools.
The error is valid and you need to fix it.
You use the "Single Page" approach ( there are two approaches "Summary page" and "Single page" )
For "Single Page" approach, you need each URL to be exactly same, and each of them should have "an anchor".
The Google developer doc clearly mentioned it.
I wrote the explanation details there
If your page contains some links to another page, then you should use "Summary Page" approach and it had different data structure ( much simpler one, I think )
No, it is NOT an error in Google's SDTT,
I have helped many people fix their structured data, including dynamic arrays. Read the instructions. Google clearly states "All values for the URL must point to the same page". Think about it, Google is trying to tell you something.
That something means this "Hey you are using a different item list from the example we provided, your item list has more than two item".
The solution:
Use anchors! Voila!
Please use this example snippet and you cannot go wrong. And another tip; use the Fetch Url option from SDTT:
<script type="application/ld+json">

</script>
you don't need to anchor every URL, you can add parameters to the URL as well ?i=1
like:
Use type OfferCatalog instead of ItemList. https://schema.org/OfferCatalog
