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

Yoast SEO. After set up 404 error pages
Hello all, Something strange happened with my blog site. I recently signed to MOZ tools. Initially everything was fine, but during my last crawl I got loads of 404
Technical SEO | | A_Fotografy
pages. Few days ago I was tweaking some settings in SEO plugin according to this post https://moz.com/blog/setup-wordpress-for-seo-success What I noticed was that 404 pages were coming from my blog posts, but for
some reason category was missing in those posts. For example this link is 404
https://a-fotografy.co.uk/inchcolm-island-wedding-photography-bailie The one with category is https://a-fotografy.co.uk/wedding-pictures/inchcolm-island-wedding-photography-bailie/ So basically for some reason category was missing. Please let me know how can I fix this instead of doing hundreds of
redirects now. Thank you,

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.

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.

Exact match subdomains
Hi, I have seen significant SEO benefits from owning exact match domains and was wondering whether exact match subdomains hold the same (or some) of these benefits? eg. halloweencostumes.co.uk vs. halloween [dot] costumes.co.uk Many thanks.

How to move my blog from subdomain to subfolder?
Not an unusual situation, I have a blog on blog.domain.com it has quite a few blog postings. The platform is old and will be scrapped, but the blog content itself is going to be moved to domain.com/blog. The current process is we are manually listing all linked to/content pages and we are going to 301 redirect them to their counterparts on the new blog. This is going to be a tedious process. A) Is there any way to automate the moving of the blog? B) What is the best way to do the massive 301 redirect, php headers, .htaccess? Should we move the individual pages with redirects, or redirect the domain in the .htaccess (this will be very difficult to match all the titles and file structure)?
