How Long Does It Take to Get a Boost in Your Product?

Etsy says it takes between 60 to 90 days for an algorithm to figure out a product's quality score. So you might not get your boost on day one, or even in the queue of products that are already being ranked by other people. You may have this thought: What if I just boost my stuff every day? And so I'll just be able to stay at the top and not have to worry about the quality score, because I'm just getting boost each day.
