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

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

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 -
MOZ Versus HUBSPOT??? If We Discontinue MOZ Subscription and Get HUBSPOT, Anything Lost?
How does Hubspot compare with MOZ? Doe it provide similar features or is the functionality very different? Is Hubspot complementary to MOZ or could it be used as a substitute? If we stopped our MOZ subscription and subscribed to Hubspot would we lose anything? Thanks, Alan

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!

What to do with a site of >50,000 pages vs. crawl limit?
What happens if you have a site in your Moz Pro campaign that has more than 50,000 pages? Would it be better to choose a sub-folder of the site to get a thorough look at that sub-folder? I have a few different large government websites that I'm tracking to see how they are fairing in rankings and SEO. They are not my own websites. I want to see how these agencies are doing compared to what the public searches for on technical topics and social issues that the agencies manage. I'm an academic looking at science communication. I am in the process of re-setting up my campaigns to get better data than I have been getting -- I am a newbie to SEO and the campaigns I slapped together a few months ago need to be set up better, such as all on the same day, making sure I've set it to include www or not for what ranks, refining my keywords, etc. I am stumped on what to do about the agency websites being really huge, and what all the options are to get good data in light of the 50,000 page crawl limit. Here is an example of what I mean: To see how EPA is doing in searches related to air quality, ideally I'd track all of EPA's web presence. www.epa.gov has 560,000 pages -- if I put in www.epa.gov for a campaign, what happens with the site having so many more pages than the 50,000 crawl limit? What do I miss out on? Can I "trust" what I get? www.epa.gov/air has only 1450 pages, so if I choose this for what I track in a campaign, the crawl will cover that subfolder completely, and I am getting a complete picture of this air-focused sub-folder ... but (1) I'll miss out on air-related pages in other sub-folders of www.epa.gov, and (2) it seems like I have so much of the 50,000-page crawl limit that I'm not using and could be using. (However, maybe that's not quite true - I'd also be tracking other sites as competitors - e.g. non-profits that advocate in air quality, industry air quality sites - and maybe those competitors count towards the 50,000-page crawl limit and would get me up to the limit? How do the competitors you choose figure into the crawl limit?) Any opinions on which I should do in general on this kind of situation? The small sub-folder vs. the full humongous site vs. is there some other way to go here that I'm not thinking of?

Use of the tilde in URLs
I just signed up for SEOMoz and sent my site through the first crawl. I use the tilde in my rewritten URLs. This threw my entire site into the Notice section 301 (permanent redirect) since each page redirects to the exact URL with the ~, not the %7e. I find conflicting information on the web - you can use the tilde in more recent coding guidelines where you couldn't in the old. It would be a huge thing to change every page in my site to use an underscore instead of a tilde int he URL. If Google is like SEOMoz and is 301 redirecting every page on the site, then I'll do it, but is it just an SEOMoz thing? I ran my site through Firebug and and all my pages show the 200 response header, not the 301 redirect. Thanks for any help you can provide.
