          Hi Everyone,

          A crawler from our SEO tool detects a 403 error from a link from our main domain to a a couple of subdomains. However, these subdomains are perfect accessibly. What could be the problem? Is this error caused by the server, the crawlbot or something else?

          I would love to hear your thoughts.
          Jens

              Hi Roman,

              Thanks for your answer!

              It's a commercial tool.

              I checked the robots.txt file and .htaccess, but didn't saw any problems.
              As you say, the problem can just be caused by the user-agent.

              If so, this will not affect my SEO efforts, right?

                Which tool are you using is this a custom tool or commercial tool such as Screamingfrog?

                  These are all for client errors. That means the page wasn’t found and something is wrong with the request. Whatever is happening though, the issue is typically on the client side:

                  403: Forbidden, So In your case, the first place that you need to check is your .htaccess and your Robots.txt file and make sure that they are not blocking any crawler or at least the crawler of your tools.

                  For example, some Hosting providers block all the crawlers that are not Google or Bing to save resources. So is usual that Roger (Moz Crawler) has problems to crawl a page that is blocked on the server side. Usually, Moz, Ahrefs, Semrush has this kind of problem so in summary

                  • Make sure your .htaccess and your Robots.txt is not blocking your crawler
                  • Make sure your hosting is not blocking your crawler
                  • If all the above does not work try to modify the user-agent of your tool

                  Hope this info helps you with your problem

                    520 Error from crawl report with Cloudflare

                    crawler cloudflare rogerbot 520 server error

                    I am getting a lot of 520 Server Error in crawl reports. I see this is related to Cloudflare. We know 520 is Cloudflare so maybe the Moz team can change this from "unknown" to "Cloudflare 520". Perhaps the Moz team can update the "how to fix" section in the reporting, if they have some possible suggestions on how to avoid seeing these in the report of if there is a real issue that needs to be addressed. At this point I don't know. There must be a solution that Moz can provide like a setting in Cloudflare that will permit the Rogerbot if Cloudflare is blocking it because it does not like its behavior or something. It could be that Rogerbot is crawling my site on a bad day or at a time when we were deploying a massive site change. If I know when my site will be down can I pause Rogerbot? I found this https://developers.cloudflare.com/support/troubleshooting/general-troubleshooting/troubleshooting-crawl-errors/

                    Find all external 404 errors/links?

                    Hi All, We have recently discovered a site was linking to our site but it was linking to an incorrect url, resulting in a 404 error. We had only found this by pure chance and wondered if there was a tool out there that will tell us when a site is linking to an incorrect url on our site? Thanks 🙂

                    Expired domain 404 crawl error

                    I recently purchased a Expired domain from auction and after I started my new site on it, I am noticing 500+ "not found" errors in Google Webmaster Tools, which are generating from the previous owner's contents.Should I use a redirection plugin to redirect those non-exist posts to any new post(s) of my site? or I should use a 301 redirect? or I should leave them just as it is without taking further action? Please advise.

                    Does an subdomain hosted offsite provide SEO value

                    We have a job board hosted through an applicant processing system which we've setup as a subdomain (jobs.ourcompany.com), most of the assets are hosted on our primary domain (ourcompany.com). My question is does having it hosted offsite provide any value? Do we get credit for that content being shared and distributed on the web or does the applicant processing system? As I see it the options are (correct me if I'm wrong): Host the job listings on our primary domain (ourcompany.com/jobs) and have it point to the application on the subdomain. Advertise the job listings pointing to the primary domain on the paid sites. The free job listing sites will automatically point to the sub-domain because the applicant processing system automatically submits them. Host the job listings entirely on the sub-domain applicant tracking system and link to it from our primary site navigation. Advertise the job listings to the sub-domain so that both free and paid point to the same place. Obviously the second one would be much easier just not sure on the technical side of our website getting credit by search engines as the one who has produced the content.

                    "Fourth-level" subdomains. Any negative impact compared with regular "third-level" subdomains?

                    Hey moz New client has a site that uses: subdomains ("third-level" stuff like location.business.com) and; "fourth-level" subdomains (location.parent.business.com) Are these fourth-level addresses at risk of being treated differently than the other subdomains? Screaming Frog, for example, doesn't return these fourth-level addresses when doing a crawl for business.com except in the External tab. But maybe I'm just configuring the crawls incorrectly. These addresses rank, but I'm worried that we're losing some link juice along the way. Any thoughts would be appreciated!

                    Do knowledge base plugins on a subdomain have seo benefit?

                    Hi SEO Moz, We want to use a knowledge base plugin (cheaper & faster than building it ourselves) where we can have Q&As for our website. We want this to help with our SEO by adding in our keyterms that we want to rank for. We've looked into TenderApp & Get Satisfaction which look like good solutions - however, as they're both on a sub-domain do we get any seo benefit from this? When people link to our knowledge base, will this help our website at all - or is the benefit going to go to TenderApp/Get Satisfaction? For instance - Our website URL is http://widget.products.com The KB URL is http://widgetsupport.products.com If the above plugin is not a good solution, is there anything else that is better? Any help will be greatly appreciated!! Thanks.

                    404 Errors After Site Migration

                    Hello - I'm working on a website selling fashion accessories.  The site just went through a site migration from Yahoo! to Big Commerce.  Now we have a high level of warnings and errors from the crawl.  Few are mentioning sites I never seen before on the Yahoo! platform. I also notice that the pages crawled has doubled.  How can I fix or did I do something wrong with migration? I was running the website with minimal errors and now overwhelmed with errors all the error updates.  If I can get some assistance on what could be wrong, I would greatly appreciate. Thanks.

                    Starting a new product, should we use new domain or subdomain

                    I'm working with a company that has a high page rank on it's main domain and is looking to launch a new business / product offering.  They are evaluating either creating a subdomain or launching a brand new domain.  In either case, their current site will link contextually to the new site.  Is there one method that would be better for SEO than the other? The new business / product is related to the main offering, but may appeal to different / new customers.  The new business / product does need it's own homepage and will have a different conversion funnel than the existing business.
