Missing Unique Product Identifiers Effects on google shopping

I love being an seo and I do love how different all my clients are…

One client hasn’t yet given me the go ahead to fix the Missing Unique Product Identifiers for the google merchant feed after months of suggesting it.

Now what’s good about this (not for the client) is I can see the difference and effect of the Missing Unique Product Identifiers on traffic from google shopping.

Below is the graph which is showing a drop in half the referrals from google shopping.

The number of items hasn’t changed nor anything else so what has changed is that the competitors have added Missing Unique Product Identifiers to all/most items which now out rank this account.

We will be gradually enforcing this policy over the next few weeks, with full enforcement in effect on June 20th. During this time, products that do not have correct unique identifiers may not appear in our product listings. If you have products that do not have correct unique identifiers, we recommend that you make the necessary changes as soon as possible.

Please note that in the weeks after June 20th, we will begin disapproving the feeds of merchants who have a significant percentage of items that do not include the correct unique identifiers.

And here is the effect:

Note the Error type and that Missing Unique Product Identifiers is at 90% so will this feed be disapproved?

I’ve spent many hours since the announcement in May working with many clients feeds to fix this issue and all other have been affected positively.

Best of luck to those who aren’t updating 😉
