Welcome to the Q&A Forum

I own the site http://www.artofwar.cc/  I have a 301 redirect rule in place to direct all non-www traffic to www.  The site is about 10 years old.  We're ranked in the top 20 in Google for around 20-40 search terms that I know of. Google Webmasters lists us as having in excess of 10000 backlinks (though many are subdomained duplicates). Majestic reports 1269 external backlinks, with the best trust/citation flows being around 40/100.  Majestic also reports 39 referring domains. I'm working through crawl errors at the moment.  The main high priority ones are 4xx errors, due to the fact that I changed some URL redirect rules a month back and am slowly getting round to changing internal backlinks in the forums.  There are no 5xx server errors, which I would think is the most likely reason Rogerbot might fall over crawling the site.  Rogerbot has no issues crawling, I've set it up in the phpBB section of the site as a registered bot, and it logs in and crawls for long periods when I manually trigger a crawl. Can anyone explain why the site might still be at DA 1?
