Let's take as example the Etsy marketplace (also, it can be eBay, Amazon or any popular marketplace).

1) As you already know, the artificial intelligence (AI) is used more and more by many marketplaces to better list the right products to the right customers, because an AI can "learn" very fast who are the people who are looking to buy products like yours.

2) Even if an AI can learn very fast who are your potential customers, it needs a huge amount of data to "learn" (this is possibile only by getting traffic). As more traffic you'll get for your shop, as faster the AI will learn who are your customers (and who are not).

3) Each week and month will help Etsy's AI to better list your products to Etsy buyers who are interested in your niche. Therefore, DO NOT make the mistake to stop the promotion of your shop, even for a single week.The promotion should never stop for your shop, if you want to get more targeted customers.

4) The AI will make many adjustements in your products ranking each month (so, it can test who are the people interested or not by your products). So, even if you'll get less sales in some weeks, it's because of AI's attempts to try to identify people who might buy from you (or not).

5) To speed up the learning process of AI and to get more sales, you have to get more visitors via multiple promotion campaigns (Etsy ads, Google ads, FB ads, cheap advertising, etc).

6) Due to the high costs of advertising from Etsy, Google, Facebook, etc.. you can try to compensate with cheap advertising like the one from us: https://proadvert9.com

So, what are you waiting for? Start getting traffic via multiple promotion campaigns, to help the AI to learn faster who are your customers!
