Business can’t scale without proper branding so you need a custom domain name with a trustworthy TLD like .com. Shoppers these days don’t just go to a single website or store and make up their minds to shop.
They keep multiple options and do a price comparison before finalizing the decision. So you have to make sure your products are not overpriced.
In my recommendation, each e-commerce business should include SEO and Pinterest in their marketing strategies. Both have remarkable ROI that can compensate if your paid marketing efforts are not yielding any results.
ConvertMate has so many free tools that let you analyze the SEO performance of your store. It also allows you to optimize the product images to give them a professional look.
