Several Google Base Errors. Please help!

Hi everyone,

As the title would suggest, I am experiencing several errors with my google base feed and literally have no clue how to fix them. Here they are:
------------------------------------------------------------------------
Feed-Level Messages
XML formatting error - Error

Missing recommended attribute: brand (1 warning)

While items missing recommended attributes will process successfully, we recommend including relevant attributes if they are available.
Examples:
Item ID Line No.
273 95 Show Item
--------------------------------------------------------

When it says 'line no.' how do I access this line to make changes? Also when it says attributes and availability etc, these items look no different than the rest, so I don't know how to resolve this.

Can anyone please help????

Anyone out there that can help?

There are extensions in the extension store that cover all the latest Google requirements.

Alternatively, there are many topics and answers in the forum on trying to fix the default OC Google Base feed.

Your only main concern is fixing the errors - The warnings are not required, so your feed wont fail on those.

@uksitebuilder

Im having similar problems, here is the message im getting from the built in auto feed:
Google Merchant Center data feed file status on "feed1": 0 of 944 items inserted‏

I have built my new site in opencart on a second domain, once its 100% done I will be switching it over to my main domain. My old site was oscommerce and I have used a script to import my product database from oscommerce, could this be what is causing the problem?

Will your extension fix my issues?

Our extension produces error free feeds yes, but it is down to the data for your products (or rather the missing data) that will determine if your products are eligible for listing on Google Shopping or not.
