X-Cart:Google Base

What the module does

X-Cart's module Google Shopping provides a tool that allows you to submit product feeds to Google Shopping so the products sold by your store can be found by Internet users using Google Shopping, a Google's service that allows users to search for products on online shopping websites and compare prices between different vendors.

Data in Google Shopping comes from two sources: product feeds submitted by merchants and a crawl of web pages that identifies product offers. A Google Shopping product feed is a text file containing specially formatted information about the products offered for sale by a store. As a merchant you can submit information about your products in the form of a product feed so your products will be listed in Google Shopping.

X-Cart's Google Shopping module facilitates creation and submission of product feeds to Google Shopping. It pulls data from all of the products in your store's database, creates a properly formatted product feed file and uses FTP to submit this file to Google Shopping.

You also have the option of downloading the product feed file to your local computer for manual submission or other usage.

Regularly submitting product feeds to Google Shopping ensures that the information about your products in Google Shopping is accurate and up to date.

Roles

If you are an X-Cart GOLD or GOLD PLUS administrator/provider or an X-Cart PLATINUM or PRO administrator:

• You can enable/disable the module Google Shopping and adjust its configuration settings (See Enabling and configuring the module).
• You can create Google Shopping feeds that will include information about all the products in the store and submit them to Google Shopping or download them onto your local computer (See Google Shopping export).

If you are an X-Cart PLATINUM or PRO provider:

• You can create Google Shopping feeds that will include information about your products and submit them to Google Shopping or download them onto your local computer (See Google Shopping export).

Enabling and configuring the module

Google Shopping is available as a built-in module in all X-Cart editions. It does not require installation and can be enabled in the Modules section of your store's Amin area.

When the module is enabled, a section titled Google Shopping options appears in General settings/Modules options.

Adjust the module settings via General settings/Modules options->Google Shopping options:

1. Provide the details of the FTP account which you are going to use for uploading data feed to Google Shopping: enter your FTP account login and password into the 'Google Shopping username' and 'Google Shopping password' fields.

To set up an FTP account for use with Google Shopping:

a) If you haven't yet done so, create a Google account and sign in to Google Merchant Center at http://www.google.com/merchants page.

b) Go to the 'Data feeds' section (http://www.google.com/merchants/bulkuploads).

c) Follow Google's instructions to create an FTP account - http://www.google.com/support/merchants/bin/answer.py?answer=160627.

2. Specify the type of currency in which you wish product prices to be displayed in Google Shopping. You should select the type of currency that is accepted by your store.

3. If you wish the customers who will come to your store from Google Shopping to come directly to the HTTPS part of the store, select the check box 'Generate links to the HTTPS part of the store'.

4. Specify, how many days the information about your products submitted to Google Shopping needs to be considered up-to-date.

5. Click the Apply changes button.

Google Shopping export

To create a product feed file for Google Shopping:

1. Make sure your product thumbnail images are stored on the file system. This is essential because the resultant product feed file will only reference images stored on the file system. If no thumbnail image for a product is found on the file system, the default 'No Image Available' file will be used for the product.

2. Go to the 'Google Shopping export' section of the store's back end:

a) Open the 'Import/export data' section of the store's back end.

• Depending on your role and the version of X-Cart you are using, you will find the Import/Export item in the Tools, Administration or Products menu.

b) Click the 'Google Shopping export' link on the 'In this section' menu:

You should see a dialog box titled 'Google Shopping export'. This dialog box allows you to perform all the operations on Google Shopping product feeds (creation of product feed files, downloading of product feed files to your local computer or submission of product feeds to Google Shopping):

3. Select a language to be used for export.

4. Make sure the filename proposed by the 'Filename' field is the name you wish to use for your Google Shopping product feed file (The filename is defined by default as username.txt - based on the Google Shopping username you specified in General settings->Google Shopping options; however, if you have more than one stores that send product feeds to Google Shopping, you might want to edit the filename so it includes your store ID - like yourstoreID_username.txt).

Note: If the 'Filename' field says froogle.txt and you do not see the Upload button, it means you probably failed to provide your FTP account details in General settings->Google Shopping options section or the current PHP configuration of your store server does not support FTP. Fix the problem to be able to submit product feeds to Google Shopping.

5. Click the Export button. The module should create a product feed.

Note: The product feed file will be saved to the directory files (if you are a store administrator) or to the directory files/your_provider_name (if you are a provider).

You should see an Information box with a confirmation message.

To download the created product feed file onto your local computer, click the Download button.

To submit the product feed file to Google Shopping directly, click the Upload button.

IMPORTANT: Please be aware that Google Shopping has some restrictions as to the format of tab-delimited bulk upload. Google's article says:

• "Do not include tabs, carriage returns, or new line characters in the attributes. If any of these appear in an attribute, we will not be able to display that item."

• "Do not include HTML tags, comments, and escape sequences. We will try to remove any HTML from your bulk upload, but for best appearance, you should not include HTML."

Because of the above restrictions, HTML tags and HTML entities are stripped from product names, descriptions, keywords and any other types of data being exported to Google Shopping.

How do I export the 'refurbished' or 'used' condition in place of 'new' for my items?

When we generate a google data feed, it lists all products as "new". We have "new" as well as "refurbished" items. How do I populate the 'condition' attribute with the value specific for each individual item in my product feed?

X-Cart 4.4.4

How can I export both UPC and MPN for my variant products?

Some (most?) manufacturers use the same UPC for multiple products and change the part number (MPN), for instance if we have a shirt with a UPC of 1234567890987 but the MPN A1231 for white, A1232 for black, A1233 for blue, etc. Is there any way to add the MPN to each product variant?

Unfortunately, additional fields, such as MPN, are not supported in product variants; besides, X-Cart does not allow adding Extra Fields to product variants. However, there is still a solution:

1) First, you can enter MPN into the SKU field for each variant, as well as for the main product (i.e. use MPN as the SKU in your store).

2) Second, make the SKU field exports as MPN to your product feed. For more details please refer to this section;

3) Finally, create an Extra Field to add UPC for the main product, so that the same UPC would be used for all the product variants. For further details, please refer to this section.

What if there are multiple UPC codes for different product variants, can these be added as well?

Actually, Google does not require to provide both UPC and MPN for each product variant. Basically, you need to submit at least two attributes of 'brand', 'gtin' (which include UPC) and 'mpn'. So, you can provide either MPN or UPC for each product variant, for example using the variant's SKU field as described above.

NOTE: If you still need to provide both UPC and MPN for each product variant in your product feed, you would need a custom modification.
