We wanted to customize our Google Base feed, so as recommended by AC, we signed up with GoDataFeed. So far it has been two or three weeks, and we are getting error message from Google every day. It has been pretty frustrating.
First of all, we did set up some custom attributes. (By the way, the drop-down menu option of the custom field still does not save properly, but that is another topic.) GDF does not format your attribute titles for you, so you will need to format them yourself exactly as Google instructed before you send them over, otherwise, you get a broken feed.
When we sent the attributes over, we explained that some of them have fixed values and some of them will have values from AC API. After two days, we had an error message, and found GDF put the one fixed value to the attribute title. So, we had to tell them to fix it.
The next day, we found our tax and shipping attributes are not correct. So, we have to go back, find out how to format the value for these two attributes, and send it over to GDF again to fix it.
Then, we found there are 18 of our attributes missing values! For sure we have the information, cause it is on the product pages, so we had to open another trouble ticket with GDF. They said they will need to talk to AC, but did not give me a time frame. It has been two weeks and our feeds are still broken!
Their custom service is nice and they reply the trouble ticket pretty fast, but every time there is an error in your feeds, it is about 24 hours turnarond time, which means you lose at least two days' sales. It is really frustrating for me at this moment, and I wish I could just do it myself , as I have done all the homework on the all the attributes. GDF claims that they are effective feeds management and they optimize, but the truth is they do upload your feed, but they do not even check what is in there. If we did not look closely, they would have been uploading our feeds with blank or wrong information all the way through.
Help someone else here would have a better solution.
