I work with furniture retailers who are mostly in this boat. It works absolute gold. If you've got store visits enabled in your analytics, you can easily prove it, too. The most efficient way depends on which ecomms platform you are on because whatever platform you are on, there's a plugin for creating Merchant Centre feeds. Make sure your product images are the absolute motza, though, that's a very critical factor here. Best of luck with it. If you ever want some friendly recommendations I've spent 2 years pretty much in this space so feel free to hit me up.
