✔️Better Focus
Since you only have to focus on optimizing and promoting one product.

✔️ Optimized marketing budget
Since it’s easier to test your advertising and calculating your budget for one product.

✔️ Higher conversion rate
Having too many choices available can overwhelm customers. Having one attractive product makes it easier for them to decide.

✔️ Branding potential
it’s generally harder for people to remember your store if you sell all sorts of products. A one-product store helps buyers connect the product to your store, and makes it easier for you to promote your brand.
