do these harm seo? or does it tag it no index so google doesnt see blank content?

 

 

also this one i dont understand at all so if someone can shed light one it would be appreciated

 

 

 

The first is saying Google was specifically instructed not to cache that page. Which is the correct thing to do. Those pages (tags, profiles, etc) are low value pages. 

For the second… The “Alternate Page with Proper Canonical Tag” status message in Google Search Console means that there are two versions of a page on your website having the same canonical URL. Google will simply exclude the duplicate version and index the main version of the page.
