Moz Insights are raising alarms --Are they useful?

[ASCI-Marketing]

Hi, Moz is alerting us about URLs being too long, titles being too long, and duplicate content. These are mostly for pages with categories of content, or the author bio pages --pages that are included by default with the template we're using in HubSpot. So that there isn't a quick way to make these changes, and anyway the pages are low-value.So my question is, how much are these issues impacting our SEO and domain authority?If these are pages no one visits (like the category and author pages) is there any reason this would be harming our SEO efforts?Thanks!
