3 Product Trends Likely to Emerge This Year
* An increase in demand for “pride” and “identity” products. Whether it is for women, certain nationalities, various rights and freedoms, you will see an increase in positive message conveying products for different segments of the population. For example, thanks to last week’s Women’s March, “pussyhats” is a popular search on Etsy.
* An increase in demand for relaxation and stress relief products. Turbulent times mean people seek out other ways to find comfort and deal with stress. A fidget cube stress reliever is currently one of the top selling products on Amazon.
* An increase in demand for products made in one’s own country. All of this talk of free trade is a reminder of how important it is to support products made in your city and/or country. There has been a notable rise in searches on Etsy and Amazon for “made in …” products, so step up your marketing efforts to your local customer base.
