I work for a company called Dynamic Creative and we've launched a new Google Shopping ads app for Shopify that creates and manages feeds and Google Shopping Ads for free. Unlike creating Shopping ads from a content API you get a transparent product feed and Google Shopping ads automatically created for every product on your website. Plus we have an award winning team of customer success managers looking after your account to help you grow and scale through your ads. We can help answer any questions you might have because we know how daunting Google Shopping can be!
We have a free plan for small businesses and you can get started on a free trial on a paid plan if you're looking to spend a little more. We want to show you what we can do for your business!
Please reach out to me if you have any questions about how we can help you or look for us in the app store 'DC Google Shopping Ads' to get started.
