Why do my Moz duplicate content results show me pages with no noticeably similar content?
-
Sometimes the "Pages with Duplicate Content" results under Content Issues show pages that, from what I'm able to see or otherwise test, have no duplicate content, save for the same navigation that exists on all of my pages.
For example, a recent issue said that the following pages had duplicate content:
https://freezerworks.com/index.php/html/slider-overlay
https://freezerworks.com/index.php/ufaqs/what-do-i-get-with-my-purchase-of-freezerworks
https://freezerworks.com/index.php/videos/fda-and-freezerworks-2
https://freezerworks.com/index.php/lims-testing-moduleEven a side-by-side of the page source in a text comparison tool shows nothing but navigation and scripts used in every page.
Am I not seeing something?

We had a similar situation and a Moz rep (thanks Samantha) pointed out in the Help material (very close to what she wrote in the earlier post) about the 90% figure. We realized the reason for the message - because the affected pages had very little content and the page header section and the page footer section (word press site) dominated the page content. We realized the issue could be ignored in our case.

Hi there,
Sam from Moz's Help Team here!
Thanks for writing in — that's an excellent question! Our tool has a 90% tolerance for duplicate content, which means it will flag any content that has 90% of the same code between pages. This includes all the source code on the page and not just the viewable text, so often it's a matter of finding the best answer for the duplicate pages in question.
If you use a Similar Page Checker like this one: https://smallseotools.com/similar-sites/ you can see that https://freezerworks.com/index.php/html/slider-overlay and https://freezerworks.com/index.php/ufaqs/what-do-i-get-with-my-purchase-of-freezerworks actually have a similarity of 96%.
There are more in-depth explanations of common answers to duplicate content on this page, if you're curious!: https://moz.com/learn/seo/duplicate-content
I hope this helps but definitely let me know if you have any other questions, or if there's anything else I can help with!

To be honest, if it's on Moz don't sweat about the error message about duplicate content, especially since can see it. However if it on GSC, take action.

Suggestion: Moz Domain Authority should take disavow into account
Since Moz is trying to predict how Google ranks your site, and Google claims to take the disavow file into account, I'd like to suggest that Moz allow webmasters to upload their disavow file. I imagine this data would be useful to Moz in determining Domain Authority (they may even think of other ways to use it and might even help come to a conclusion on the great debate) and it gives a chance for sites to improve their Moz DA when they are bombarded by spammy links. I'd love to hear the community's thoughts on this idea, as well as the what Wizards of Moz have to say.

How Does the On-Page Grader Know about my Target Keyword? Or how can I tell it?
So we've optimized a home page for a particular keyword, "blue widgets tx". But the on-page grader is giving information about "tx blue widgets", "blue widgets in texas", etc. and telling us we are an "F" for these keywords. Is it possible to tell the on-page grader, "Hey, just worry about 'blue widgets tx', and forget about those other ones"? I know I can do it by hand, but it will take forever.

Monthly Data Option not appearing in Moz AGAIN
Hello Again, It's a real shame that I seem to come to this forum to only complain about your product again and again. I remember a time when I used to really respect this company, but your tool is absolutely abysmal. Anyway, my latest issue (to add to the pile) is that campaigns that have been in my account for almost 2 months STILL do have options for me to make monthly reports on. What's wrong now? Edit: I just checked the date I added these profiles, it was around the end of last month, so one and a half months ago.

On Page reporting Issue
Hi I’ve recently downloaded my onpage analysis report for our site http://www.health2000.co.nz . The column that is titled “Missing data description Tag” says false, which I’m assuming means the meta description is present. However in the column titled “meta _description tag” there is no meta description present (nor is any meta description in the backend of my site. Could someone please explain why this would occur? I look forward to hearing from you Regards Pete

Why my on-page report card won't improve?
For my page www.homedestination.com/Minneapolis-homes-for-sale.html, Moz ranks the page as an "F" for the keyword "Minneapolis home buyers". All data in the report card is from months ago. using the "Grade my On-Page Optimization" button fails to show any updates - even after months. For example the title is actually "Minneapolis Homes For Sale| buying a Minneapolis home | Homebuyers" while Moz says it is ""Minneapolis Homes For Sale | Home Destination | Jenna Thuening" Moz says the description tag is "Realtor Jenna Theuning helping real estate buyers find Minnetonka homes for sale, owner of Home Destination. CDPE also helps with foreclosure and short sales buying." and "Minneapolis homes for sale, and Minneapolis listing, and Minneapolis upscale real estate, and Minneapolis lakeside properties provided by Home Destination"" when it is actually "Minneapolis homes for sale, and Minneapolis listing, Minneapolis home buyers, and Minneapolis lakeside properties provided by Home Destination." Additionally, my weekly ranking reports seems "stuck" and continues to show many "F" ranked keywords that have been updated for some time. Amy advice on how to see improvements?

How do you stop Moz crawling a page?
Hello, I have a contact form which generates thousands of duplicate crawl errors. I'm going to use to block Google indexing these pages. Will this also block MOZ from crawling these pages and displaying the error? Thanks!
