Based on the 'quality score' you have mentioned, deleting poor content pages from a site could help.
No I am not saying that deleting poor quality pages will always help. We never know all the signals they use and the sample pages they choose to evaluate, to arrive at the overall quality score for a site. Many site owners are deleting what they think are poor quality pages. But they may not always be right.
