Welcome to the Q&A Forum

Hi Sean In my experience there are always many differences in the crawl reports from Moz and Webmaster Tools. Bear in mind, they are all just computer programs running automatically to detect "issues" - and that a human eye is the best tool at the end of the day. To step back a little, your overall ranking will likely have very little to do with these sorts of things (titles, descriptions, etc). They can have a small effect but will usually not bump the needle way up. So just keep that in perspective when fixing things. In general, I would aim to have your titles and descriptions unique, within length guidelines, compelling for users and so on. Google has a great guide here: https://support.google.com/webmasters/answer/35624?hl=en There can sometimes be a delay in what Google shows you in WMT as well. They might not have crawled everything as recently as Moz. I do tend to find Moz will check everything whereas WMT will only alert you to the pages they find are problematic. (For example, you might have pages with duplicate titles, but Google has determined the pages not important - a quality check if you well - whereas Moz doesn't make this qualitative check, they just crawl and rate everything). In order of priority I would fix WMT issues first and then move to Moz issues. But again, your overall ranking is likely more due to site authority & trust as measured by links and usage.
