I have no reason why, but in my experience if we make even the slightest functionality change to our website, our sales seem to dry considerably immediately and then pickup within a few days/weeks (actually I know a reason why- people are unfamiliar with our site but bookmark it to possibly buy later and get spooked by the change). The same might be happening with your new and improved site.
Be careful about pausing any advertising completely. If you're operating in a cyclical or seasonal industry, people may be window shopping but not quite in a position to buy yet and you'll be losing sales down the road.
More SKUs can be dangerous. It's easy to assume 1000 skus should make 10x more profit than 100 skus (and if not 10x at least 5x!). A well curated site can be a great competitive advantage. And after all, there's a reasonw why supermarkets don't offer 20 different brands of ketchups.
