Welcome to the Q&A Forum

I am trying to figure out fb:admin tag.  I noticed that Moz uses a person's from hubspot,  is this because hubspot connects into their facebook data? Who should my company set it to?   Any guides would be helpful. Thanks, Chris

My site has tons of summary pages,  Whether for a PDF download, a landing page or for an article.  There is a summary page, that explains the asset and contains a link to the actual asset. My question is that if the summary page is just  summary of an article with a "click here to read full article" button,  Should I set the rel canonical on the summary page to go to the full article? Thanks,
