Migrated from WooCommerce to Shopify. And changed from Google Ads to Facebook, sales drastically fell.

The site has better functionality now. It is quicker and more intuitive. Still, sales aren't that good. The conversion ratio is currently on 0.1%

Facebook ads are not done by me, since I have other tasks to do, this is outsourced. The problem now is, we get about 500 views a day, which should convert at least to 1% instead of 1/10th of that.

Might it be that audiences on Facebook think differently? I mean, if they click on the add, it should work by my estimation.

Market: Interior design.

Help is greatly appreciated!
