my e-commerce website don't rank

hello, i launched my ecom website 3 months ago, at first my website was in 5 impressions daily but then to 2/1 ( it was a really bad content) . i changed content there is 1,5 month ( still IA but not really wow content, but still better than the first). but im still at 5 impressions, is it a content problem? because i optimised my meta titles, tags, speed, hn tags etc. and its not a really competitive niche. is it a content problem? and should i change it ? thanks.
