AR: Google Shopping Feed Pro

Very helpful and great service! Any problems - just ask and receive a fast reply.
Thanks so much! Would recommend it to any small business.

App works great, but that's not the best thing. Their customer service if you have an issue is second to none, they are amazing! Would highly recommend this app to anyone in need of Google Merchant help like I was.

Fantastic app - such a simple way to feed Google Shopping! I struggled for ages trying to connect directly from Shopify, with this we were up and running almost straight away. Can't recommend highly enough.

We needed to have feeds in multiple currencies and ready for multiple domains. We contacted support and they were able to create the feed and guide us through the process fast. Very satisfied!

I've been using this app for approximately a year now, and I am extremely satisfied with it. During this time, I encountered some internal complications that required a reinstallation and reaching out to the support team for assistance. The support I received was incredibly helpful and responsive. The app has been functioning perfectly for me 100% of the time. With the level of support and responsiveness I've experienced, I can't give anything less than 5 stars.

UPDATE:
I've just recently also had a lot of customized requets to make it adjustable for affiliate sites, marketplaces ect and the help and respons time from Improve / Apps Robots HAVE BEEN OUTSTANDING. Fastest and easiest experience I've ever had.

Dennis from the support team was incredibly helpful. We required assistance with transitioning from a different feed app to ensure that our Ads retained all the campaign statistics and to expand our Adword campaigns to a second country. Since I was uncertain about the setup process and didn't want our ad campaign to undergo a relearning phase or encounter any issues with incorrect IDs, Dennis took care of everything for me. The support provided was exceptional, and the app itself is fantastic. I highly recommend both the support team and the app.

Really love this app. Specially satisfied about its service and I will definitely recommend this app to others.

Simple setup and does what it claims. It creates a feed that includes all variants for a fair price. Well worth the price. Only ever contacted support before purchasing, and response was quick and helpful.

Super easy to set up and use. I've been using this app for a while and I've had no issues. I can definitely reccomend.

We needed to manage our own Google Merchant Center feed. Not only will this app give you a great feed, but it gives you a jump start by intelligently setting your products up in Merchant Center. The support is amazing and the help documentation is full of useful understandable information.
If you need GTINs to bring your products to approval status, look no further. We had issues with missing GTINs and duplicate GTINs on some products. Support found us a reseller of valid GTINs at a low price for our products which then got approved in Google Merchant.
We have seen a boost in sales of those products since setting up our feed with this app. Give it a try. You will not be disappointed!
