What news sources do you rely on for information on eCommerce? Does it keep you up to date with current changes? Do you trust their information or find you need to verify things on your own?
I watch YouTube videos on Shopify and from YouTubers that have successful e-commerce store.
I also watch a channel on YouTube that's dedicated to drop shipping and everything e-commerce, look for 'OBERLO' on YouTube
Depending on your particular role and interests, you may be interested in the latest news about eBay, Amazon, Alibaba, or other ecommerce marketplaces. Or maybe you run your own ecommerce store and want to improve your Google ads, your social media strategy, or your conversion rates to increase online sales.
