Making money through e-commerce involves two main methods: dropshipping, where you sell products without holding inventory by partnering with suppliers who handle storage and shipping, and selling products you make yourself, which requires managing your own inventory and production. Combining these approaches can diversify your offerings, increase revenue, and provide flexibility in managing your business. Key strategies include identifying profitable niches, optimizing your website for search engines, leveraging social media and email marketing, and using targeted advertising to drive traffic.
