Trending products are the best for dropshipping for the main reason - online store owners stop losing money on ads and still generate sales. When dropshippers have product ideas, they refer to Google trends
to depict if the items are recently popular,
as it's reasonable to dropship items on demand. Note
: Trending products may be not good for dropshipping in one case when the trend has overpassed its high pick and have a negative inclination. If you start selling goods that seem to be trendy, spending money on promotion and having no sales, you may lose invested capital. So, actual continuity of trends is an important feature.
Paradigmatic example: everybody remembers the hype about "fidget spinners" niche. This product was trendy indeed and dropshippers earned insanely much. Those who started to dropship fidget spinners after July 2017 earned zero or even lost money on ads.
