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

WEbsite cannot be crawled
I have received the following message from MOZ on a few of our websites now Our crawler was not able to access the robots.txt file on your site. This often occurs because of a server error from the robots.txt. Although this may have been caused by a temporary outage, we recommend making sure your robots.txt file is accessible and that your network and server are working correctly. Typically errors like this should be investigated and fixed by the site webmaster. I have spoken with our webmaster and they have advised the below: The Robots.txt file is definitely there on all pages and Google is able to crawl for these files. Moz however is having some difficulty with finding the files when there is a particular redirect in place. For example, the page currently redirects from threecounties.co.uk/ to https://www.threecounties.co.uk/ and when this happens, the Moz crawler cannot find the robots.txt on the first URL and this generates the reports you have been receiving. From what I understand, this is a flaw with the Moz software and not something that we could fix form our end. _Going forward, something we could do is remove these rewrite rules to www., but these are useful redirects and removing them would likely have SEO implications. _ Has anyone else had this issue and is there anything we can do to rectify, or should we leave as is?

Robots.txt blocking Moz
Moz are reporting the robots.txt file is blocking them from crawling one of our websites. But as far as we can see this file is exactly the same as the robots.txt files on other websites that Moz is crawling without problems. We have never come up against this before, even with this site. Our stats show Rogerbot attempting to crawl our site, but it receives a 404 error. Can anyone enlighten us to the problem please? http://www.wychwoodflooring.com -Christina

Should I set blog category/tag pages as "noindex"? If so, how do I prevent "meta noindex" Moz crawl errors for those pages?
From what I can tell, SEO experts recommend setting blog category and tag pages (ie. "http://site.com/blog/tag/some-product") as "noindex, follow" in order to keep the page quality of indexable pages high. However, I just received a slew of critical crawl warnings from Moz for having these pages set to "noindex." Should the pages be indexed? If not, why am I receiving critical crawl warnings from Moz and how do I prevent this?

Is one page with long content better than multiple pages with shorter content?
(Note, the site links are from a sandbox site and has very low DA or PA) If you look at this page, you will see at the bottom a lengthy article detailing all of the properties of the product categories in the links above. http://www.aspensecurityfasteners.com/Screws-s/432.htm My question is, is there more SEO value in having the one long article in the general product category page, or in breaking up the content and moving the sub-topics as content to the more specific sub-category pages? e.g. http://www.aspensecurityfasteners.com/Screws-Button-Head-Socket-s/1579.htm

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!
