In August 2015 Google updated the feed requirements for merchants using Google Shopping. This meant that retailers were now required to send the GTIN (Global Trade Item Numbers) for any products listed as new and from a list of designated brands.
Going forward in 2016
In a recent update, Google announced that they'd be expanding GTIN requirements beyond those 50 brands to include all items with a GTIN assigned by the manufacturer. Google claim that merchants who've added the correct GTINs to their products have seen conversion rates increase by 20%.
A key part of succeeding in Google Shopping is creating a good product and data feed. As with any Google service, the better optimised your feed is, the more likely they are to display your listings over your competitors.
Google commented "We've found that providing GTINs in your product data feed increases the likelihood that your offers are matched to the Google Shopping product catalog. This helps us surface relevant, accurate results on Google Shopping"
What does this mean for retailers?
When the first updated feed specification was rolled out in September of last year; many retailers found that their once healthy merchant centre was full of feed errors requesting GTINs for designated brands. If you weren't already sending a GTIN to Google, you would have needed to send an updated XML or manual upload to ensure that this was included. For those that were sending them, the hunt was on for valid GTINs.
Today, if you sell new, brand-name products, you'll need to review your in-house GTIN policy and double check that your feed and product data is up to specification. If you're selling own brand goods, this change is unlikely to affect you. Similarly, if you're selling used or custom made products you won't be impacted by the update.
If you are selling in/targeting Australia, Brazil, the Czech Republic, France, Germany, Italy, Japan, the Netherlands, Spain, Switzerland, the UK, or the US, you'll need to submit a new feed with valid GTINs.
GTINs vary in length depending on the product being sold. Below is a list of the different identifiers you may encounter:
- UPC (in North America / GTIN-12): 12-digit number (8-digit UPC-E codes should be converted to 12-digit UPC-A codes)
- EAN (in Europe / GTIN-13): 13-digit number
- JAN (in Japan / GTIN-13): 8 or 13-digit number
- ISBN (for books): 13-digit number (ISBN-10 values should be converted to ISBN-13)
- ITF-14 (for multipacks / GTIN-14): 14-digit number

Updating your feed
If you've been in the Merchant Centre recently you will have seen low-level warnings from Google requesting you add GTINs to new, branded products by May 16th 2016. As with the previous update, Google have set a deadline for the new GTIN requirements to be met if they are to continue serving your ads.
We would highly recommend updating your product data ahead of the deadline as once your products are disapproved, it can sometimes take up to 48hrs for them to be re-approved; that's loss of revenue and visibility. You also run the risk of account suspension if you do not make the required updates in time.
