Block Moz (or any other robot) from crawling pages with specific URLs
-
Hello!
Moz reports that my site has around 380 duplicate page content. Most of them come from dynamic generated URLs that have some specific parameters. I have sorted this out for Google in webmaster tools (the new Google Search Console) by blocking the pages with these parameters. However, Moz is still reporting the same amount of duplicate content pages and, to stop it, I know I must use robots.txt. The trick is that, I don't want to block every page, but just the pages with specific parameters. I want to do this because among these 380 pages there are some other pages with no parameters (or different parameters) that I need to take care of. Basically, I need to clean this list to be able to use the feature properly in the future.
I have read through Moz forums and found a few topics related to this, but there is no clear answer on how to block only pages with specific URLs. Therefore, I have done my research and come up with these lines for robots.txt:
User-agent: dotbot
Disallow: /*numberOfStars=0User-agent: rogerbot
Disallow: /*numberOfStars=0My questions:
1. Are the above lines correct and would block Moz (dotbot and rogerbot) from crawling only pages that have numberOfStars=0 parameter in their URLs, leaving other pages intact?
2. Do I need to have an empty line between the two groups? (I mean between "Disallow: /*numberOfStars=0" and "User-agent: rogerbot")? (or does it even matter?)
I think this would help many people as there is no clear answer on how to block crawling only pages with specific URLs. Moreover, this should be valid for any robot out there.
Thank you for your help!

Hello!
Thanks a lot for your feedback and clearing this out! It worked well.
The robots.txt tester is a good tip!
Thanks!

Hi,
What you have there will work absolutely fine with a little tweak. And no need to leave spaces between lines.
Disallow: /numberOfStars=0
However, no need to add the wildcard at the end if there is nothing more after that.
The best way to test what works, is before you go and add it to live, use the Robots.txt test tool in Search Console (Webmaster Tools), add in the lines above and then check to make sure none of your other pages are blocked. They won't be, but it's a great way to test before going live.
I hope this helps

Moz-Specific 404 Errors Jumped with URLs that don't exist
Hello, I'm going to try and be as specific as possible concerning this weird issue, but I'd rather not say specific info about the site unless you think it's pertinent. So to summarize, we have a website that's owned by a company that is a division of another company. For reference, we'll say that: OURSITE.com is owned by COMPANY1 which is owned by AGENCY1 This morning, we got about 7,000 new errors in MOZ only (these errors are not in Search Console) for URLs with the company name or the agency name at the end of the url. So, let's say one post is: OURSITE.com/the-article/ This morning we have an error in MOZ for URLs OURSITE.com/the-article/COMPANY1 OURSITE.com/the-article/AGENCY1 x 7000+ articles we have created. Every single post ever created is now an error in MOZ because of these two URL additions that seem to come out of nowhere. These URLs are not in our Sitemaps, they are not in Google... They simply don't exist and yet MOZ created an an error with them. Unless they exist and I don't see them. Obviously there's a link to each company and agency site on the site in the about us section, but that's it.

URL Length Issue
MOZ is telling me the URLs are too long. I did a little research and I found out that the length of the URLs is not really a serious problem. In fact, others recommend ignoring the situation. Even on their blog I found this explanation: "Shorter URLs are generally preferable. You do not need to take this to the extreme, and if your URL is already less than 50-60 characters, do not worry about it at all. But if you have URLs pushing 100+ characters, there's probably an opportunity to rewrite them and gain value. This is not a direct problem with Google or Bing - the search engines can process long URLs without much trouble. The issue, instead, lies with usability and user experience. Shorter URLs are easier to parse, copy and paste, share on social media, and embed, and while these may all add up to a fractional improvement in sharing or amplification, every tweet, like, share, pin, email, and link matters (either directly or, often, indirectly)." And yet, I have these questions: In this case, why do I get this error telling me that the urls are too long, and what are the best practices to get this out? Thank You

Pages with URL Too Long
Hello Mozzers! MOZ keeps kindly telling me the URLs are too long. However, this is largely due to the structure of E-commerce site, which has to include 'brand' 'range' and 'products' keyword. For example -
Moz Pro | | tigersohelll
https://www.choicefurnituresuperstore.co.uk/Devonshire-Rustic-Oak-Bedside-Cabinet-1-Drawer-p40668.html MOZ recommends no more than 75 characters. This means we have 25-30 characters for both the brand name and product name. Questions:
If it is an issue, how to fix it on my site?
If it's not an issue, how can we turn off this alert from MOZ?
Anyone know how big an issue URLs are as a ranking factor? I thought pretty low.0 -

Pages with Temporary Redirects on pages that don't exist!
Hi There Another obvious question to some I hope. I ran my first report using the Moz crawler and I have a bunch of pages with temporary redirects as a medium level issue showing up. Trouble is the pages don't exist so they are being redirected to my custom 404 page. So for example I have a URL in the report being called up from lord only knows where!: www.domain.com/pdf/home.aspx This doesn't exist, I have only 1 home.aspx page and it's in the root directory! but it is giving a temp redirect to my 404 page as I would expect but that then leads to a MOZ error as outlined. So basically you could randomize any url up and it would give this error so I am trying to work out how I deal with it before Google starts to notice or before a competitor starts to throw all kinds at my site generating these errors. Any steering on this would be much appreciated!

Canonical URLs all show trailing slash on main site pages - using Yoast SEO for Wordpress - how to correct
We are using Yoast for a number of our sites. We use naked domain as the canonical. I have noticed in the header tags that all our sites show the canonical URLs as having a trailing slash: Example: http;//foxspizzajc.com, when I look at the source code, it shows the canonical as http;//foxspizzajc.com/ Of course, it is much more likely that all sites that link to us will not use the trailing slash - so preferably we do not want that to be the canonical - among other reasons. Does this need to be fixed so the trailing slash is removed? I cannot see how to do this in Yoast SEO or in Permalinks structure for Wordpress. Sorry for my ignorance. Thanks for any help.

Page Authority is the same on every page of my site
I'm analyzing a site and the page authority is the exact same for every page in the site. How can this be since the page authority is supposed to be unique to each page?
