Abnormal crawl issues appearing in my Moz results
-
I have been asked to look at a site for a friend and was more than surprised to see 16,9k crawl issues appear in the dashboard... of this 6,238 are duplicate page content and 5878 are duplicated page titles.
What on earth is going on? I have spoken to the web developer as it appears there is a dev site somewhere and this is his response
[Can I stress that Google determines which site was in the index first and then removes other sites it sees as having duplicate content. Our dev sites appearing in the search index would not affect your ranking due to duplicate content as Google would see your site as the first site with the content]
As I cannot make contact with him, I am scratching my head, surely a dev site should be no-indexed, it sounds as though he is saying that its ok because Google will take the main site as the first site with the content...
Very confused! Help need MOZ community.
Manythanks,

Hi Sarah,
Googlebot will follow these links as well and discover these "useless" pages (the are off course not useless from human perspective but they don't add value for bots - and they will be considered as duplicates). Duplicates are no reason for "punishment" - so you could just let them be. Personally I would put a nofollow on these links or add a "noindex" tag to the login page. Normally you shouldn't use nofollow on internal links - but login pages are an exemption on this (check also https://searchenginewatch.com/sew/news/2298312/matt-cutts-you-dont-have-to-nofollow-internal-links : "Of course, there are always exceptions to the rule, and things like login pages can be the exception. He said it doesn’t hurt to put the nofollow link for a link pointing to a login page, or things like terms and conditions or other “useless” pages. However, it doesn’t hurt at all for those pages to be crawled by Google."
For the practical part - if you add an additional question to a question which has been marked as answered - only the ones who have already answered will see the additional question. To be on the safe side - it's better open a new question if you want other people to have a look at it.
Hope this helps,
Dirk

hello Dirk, thank you for that great answer, we have since been doing a bit more digging of our own and before we go back to the web developer we want to check what should be happening with the links the we are finding duplicated as we are seeing that the issues relating to Duplicate Pages are coming from links from the login page which shows information about where the user was redirected from.
For example, if the visitor is not logged on and wishes to wish-list an item, they will be redirected to the login page, with the item code and intended action in the url; which can then continue on to the desired page once logged on.
The MOZ crawler is seeing these pages as having Duplicated Content whilst they are all the same apart from a piece of information in the URL. Should we be blocking these duplications? Are they a risk to us? What should we be doing?
I have also added this as a new question - I am quite new to this community thing so wasn't sure which was the best way to ask the question.
Many thanks again,
Sarah

Moz is only indexing pages it's crawler is able to find. This implies that on your production site you have links to your development site.
Don't really agree with what your dev is saying - he should correct these links first; put a noindex on these pages. Alternative - put a password on the dev site so it's only accessible with a password. If a lot of users are putting links to your dev site it could become more important than your main site. Google will try to choose the most appropriate site - but you have no guarantee that it will choose the right version. In any case - that's not the type of risk you should be willing to take.
Once this is done - you can request a removal of these pages via the search console.
If all pages are removed from the index you can adapt the robots.txt to prevent access to the Google & other bots. Do this only after all pages are removed - if not Google will never find the noindex directive.

Possible Crawling Problem with Screaming Frog and Moz Crawlers
So I'm not sure if what I'm seeing is a problem or not. As of about two weeks ago the Moz crawler has only been able to see www.mysite.com, and none of the links, content, title, ect associated with the page. Essentially the report has one line, what should be the homepage, but it's not able to pull any information from the page but does show a 200 http status code. The report shows nothing blocked by robots or any errors. When I use screaming frog to crawl the site about 75% of the time it just reports one line www.mysite.com with a 200 status code, but again the crawler is not able to actually see the html. The other 25% of the time it works perfectly fine, crawls all pages and sees all meta info and content. There are no errors in Google WMT and everything looks ok there. We have seen a traffic drop the last two weeks but I don't know if this is the reason for it. I can't publicly post the page but if someone has an idea of what might be going on I'd be happy to PM them. Thanks

Joomla Opencart Duplicate Link Issue
With a few recent catalog changes my client is having tons of duplicate content issues. The most peculiar is one that I cannot see visibly on the site pages. This page: http://www.CLIENTDOMAIN.com/catalog/lights.html shows to have several duplicate content issues with URLs such as: http://www.CLIENTDOMAIN.com/catalog/lights/Lamp-DRW.htmlhttp:/www.CLIENTDOMAIN.com - where the domain is basically added to the end of the first URL. Has anyone seen this? Any fixes, plugins or thoughts? Thanks,

What exactly is Moz Analytics?
I've taken a look at this page - http://moz.com/products/tour and I'm trying to determine if Moz Analytics is live yet? I don't think it is, just wanted to make sure. Because right now I'm just seeing all the same tools as we've always had + Fresh Web Explorer. Anyways, let me know if I'm missing something.
