          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?

                  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

                    GMB Bulk Upload Error

                    Hello! I am continuing to have issues with the bulk upload option.Currently, there are 12 non-verified locations in a location group in my GMB account. I have approximately 6-8 more that need to be added to this group via bulk upload. When uploading the spreadsheet, I receive an error reading "You've exceeded the limit for the about of locations you can upload to Google My Business in a single day. Try again later." It seems to happen specifically to the locations that aren't in my GMB account already. The others, the ones already in the account, are fine and simply read "No updates" when the bulk upload sheet is read. Everything else is marked as an error. Why is it marking some listings as nonviable when they come in via the bulk verification spreadsheet, which has been downloaded directly from the links Google has provided, and filled in with the help of the sample and amenities list?How do we finish uploading all of the remaining locations?I have another group, separate group (same company, groups split into US and International) under my name that may also need a bulk upload - what can I do to avoid this error in the future? Can they still be bulk uploaded to my account after I upload the first location group's listings?If you could provide any guidance, I'd be very grateful.Thanks in advance!

                    Removing site subdomains from Google search

                    Hi everyone, I hope you are having a good week? My website has several subdomains that I had shut down some time back and pages on these subdomains are still appearing in the Google search result pages. I want all the URLs from these subdomains to stop appearing in the Google search result pages and I was hoping to see if anyone can help me with this. The subdomains are no longer under my control as I don't have web hosting for these sites (so these subdomain sites just show a default hosting server page). Because of this, I cannot verify these in search console and submit a url/site removal request to Google. In total, there are about 70 pages from these subdomains showing up in Google at the moment and I'm concerned in case these pages have any negative impacts on my SEO. Thanks for taking the time to read my post.

                    Migrating to new subdomain with new site and new content.

                    Our marketing department has decided that a new site with new content is needed to launch new products and support our existing ones. We cannot use the same subdomain(www = old subdomain  and ww1 = new subdomain)as there is a technically clash between the windows server currently used, and the lamp stack required to run the new wordpress based CMS and site. We also have an aging piece of SAAS software on the www domain which is makes moving it to it's own subdomain far too risky. 301's have been floated as a way of managing the transition. I'm not too keen on that idea due to the double effect of new subdomain and content, and the SEO impact it might have. I've suggested uploading the new site to the new subdomain while leaving the old site in place. Then gradually migrating sections over before turning parts of the old site off and using a 301 at that point to finalise the move. The old site would inform user's there is a new version and it would then convert them to the new site(along with a cookie to auto redirect them in future.) while still leaving the old content in place for existing search traffic, bookmarks and visitors via static URLs. Before turning off sections on the old site we would create rel canonicals to redirect to the new pages based on a a mapped set of URLs(this in itself concerns me as the rel canonical is essentially linking to different content). Would be grateful for any advice on whether this strategy is flawed or whether another strategy might be more suitable?

                    Blogs are best when hosted on domain, subdomain, or...?

                    I’ve heard the it is a best practice to host your blog within your site. I’ve also heard it’s best to put it on a subdomain.  What do you believe is the best home for your blog and why?

                    404 errors on non-existent URLs

                    Hey guys and gals, First Moz Q&A for me and really looking forward to being part of the community. I hope as my first question this isn't a stupid one but I was just struggling to find any resource that dealt with the issue and am just looking for some general advice. Basically a client has raised a problem with 404 error pages - or the lack thereof- on non-existent URLs on their site; let's say for example: 'greatbeachtowels.com/beach-towels/asdfas' Obviously content never existed on this page so its not like you're saying 'hey, sorry this isn't here anymore'; its more like- 'there was never anything here in the first place'. Currently in this fictitious example typing in 'greatbeachtowels.com/beach-towels/asdfas**'** returns the same content as the 'greatbeachtowels.com/beach-towels' page which I appreciate isn't ideal. What I was wondering is how far do you take this issue- I've seen examples here on the seomoz site where you can edit the URI in a similar manner and it returns the same content as the parent page but with the alternate address. Should 404's be added across all folders on a site in a similar way? How often would this scenario be and issue particularly for internal pages two or three clicks down? I suppose unless someone linked to a page with a misspelled URL... Also would it be worth placing 301 redirects on a small number of common mis-spellings or typos e.g. 'greatbeachtowels.com/beach-towles' to the correct URLs as opposed to just 404s? Many thanks in advance.
