Create a multistore
Todays webstore customers tends to trust niche stores that is run by experts more that general webstores that sells anything. Thats because niche stores often are runned by people who have a real interest in what they sell, and therefor sell quality products.

You can use that to your advantage by creating several niche stores from you store that sells a lot of different items. If you run a camera store you can create niche stores from it by creating stand alone stores that sells only products from categories in your store.

Create a dashcam store, a store for only camera equipment, as store for only Nikon cameras, and become an “expert” on that fields.
