Subdomain 403 error
-
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.

no at all

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

Subdomain or subfolder?
Hello, We are working on a new site. The idea of the site is to have an ecommerce shop, but the homepage will be a content page, basically a blog page.
Technical SEO | | pinder325
My developer wants to have the blog (home) page on a subdomain, so blog.example.com, because it will be easier to make a nice content page this way, and the the rest of the site will just be on the root domain (example.com). I'm just worried that this will be bad for our SEO efforts. I've always thought it was better to use a sub folder rather than a subdomain. If we get links to the content on the subdomain, will the link juice flow to the shop, on the root domain? What are your thoughts?0 -
Sitemap error in Webmaster tools - 409 error (conflict)
Hey guys, I'm getting this weird error when I submit my sitemap to Google. It says I'm getting a 409 error in my post-sitemap.xml file (https://cleargear.com/post-sitemap.xml). But when I check it, it looks totally fine. I am using YoastSEO to generate the sitemap.xml file. Has anyone else experienced this? Is this a big deal? If so, Does anyone know how to fix? Thanks EwTswL4

Hundreds of 404 errors are showing up for pages that never existed
For our site, Google is suddenly reporting hundreds of 404 errors, but the pages they are reporting never existed. The links Google shows are clearly spam style, but the website hasn't been hacked. This happened a few weeks ago, and after a couple days they disappeared from WMT. What's the deal? Screen-Shot-2016-02-29-at-9.35.18-AM.png

"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!

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.

Robots.txt file getting a 500 error - is this a problem?
Hello all! While doing some routine health checks on a few of our client sites, I spotted that a new client of ours - who's website was not designed built by us - is returning a 500 internal server error when I try to look at the robots.txt file. As we don't host / maintain their site, I would have to go through their head office to get this changed, which isn't a problem but I just wanted to check whether this error will actually be having a negative effect on their site / whether there's a benefit to getting this changed? Thanks in advance!

Should there be a canonical tag on my 404 error page?
In my crawl diagnostics, I notice some 4xx client errors. They are appearing for pages that no longer exist, so I'm not sure what the problem is. Shouldn't they just be dealt as 404's? Anyway, on closer inspection I noticed that my 404 error page contains a canonical tag which points to the missing page. Could this be the issue? Is it a good idea to remove the canonical tag from this error page? Thanks.
