Error in Google SDTT: "All values provided for url must point to the same page."

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.

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 )

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.
