How to Feature Your Product through Google Shopping | Magento

by

Follow these steps if you want to feature your Magento products through Google Shopping. First will explain you how to setup your own Google Merchant Center (formerly known as Google Base). Secondly, we’ll point out some potential issues that you might run into when setting this all up.

Step 1: Setting up the Google Merchant Center

Head over to Google Merchant Center page to create a Google Merchant account. Important note: While you’re able to add additional users to one Google Merchant Center account through Users tab in Settings, every Google account can be associated with only one Google Merchant Center Account.

Step 2: Generating a Magento product feed with Amasty Extension

While there are several solutions in form of extensions out there and you can even custom develop one (which is not recommendable). Believe me, you don’t need the in-house solution, there is even an official extension by Magento called Google Content API for shopping, but that extension seem to have a lot of issues judging by it’s reviews. I’d probably try some of the other solutions.

We recommend just using a tested ready made Magento Extension:  Amasty Product Feed – which will create product feeds for Google Shopping, Nextag, Bing, Amazon and many other.

We tried it on several projects and compared to other feed generating solutions it’s much more flexible, meets a lot of needs and has fewer bugs.

Step 3: Mapping your Magento categories according taxonomy

One thing you must keep in mind that’s not mentioned in Google Support or in feed specification is that Google has a different product taxonomy for each country. This means that, altough the language is pretty much the same, some things are actually differently organized in UK taxonomy than in US taxonomy.

Step 4: Test the new product feed

Once you’ve generated your product feed, it’s time to upload it into the Google Merchant Center and test it. Within GMC, go to the data feeds tab.

There are two different upload buttons: “New Data Feed” and “New Test Data Feed”. Use the test feed to test if your feed is generated correctly.

Step 5: Add your product feed to GMC

Once you tested the feed and solved any issues, go to the data feeds tab once again and add your feed using a “New Data Feed” button. You can create a schedule for Google Merchant Center to automatically fetch your data feed at certain time of the day every day, week or month. In most cases I’d recommend generating and fetching the feed daily.

Potential Reasons for Google Merchant Center to disapprove your products:

The most common reason for Google to disapprove your products are your images. For apparel products images must be at least 250x250px. Max image size for any category is 4MB. If your products (apparel) come in several colors or even sizes, Google requires a different image for each variation.

Your images may not have a watermark on them. Your images must be crawl-able by Google, make sure you didn’t block them by robots.txt disallow or if they are on CDN make sure your CDN is not blocking them with CDN’s robots.txt disallow.

Apparel products must have a color. It can’t be a pattern (you can’t put “chevron pattern” under color attribute). You must use the “dominant” color instead, and you may add additional colors. Also color can’t be #ffffff, it needs to be the actual name of the color “white” or “black” or “red” etc.

Your price might have changed between the time you generated the feed and the time someone reviewed the products in your feed. If price is different in the feed compared to the price on the live store, your products will get disapproved.

Product reviews in Google shopping ads

Google recently started including product reviews into their shopping ads. This is only available in the USA, but when it comes to features such as this one we can expect it to roll out into UK and some other countries soon as well.

To be able to display your product reviews (and star rating) within your Google shopping ads, you need to either use one of the authorized 3rd party review systems (fore full list scroll down in this article) or create a product review feed.

If you use your own product review system, as I mentioned, you’ll need to create a review feed. There are two types of feed supported, a full feed and an incremental feed. Click here for feed specifications and here for a sample feed.
