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

Is there any benefit in using a subdomain redirected to a single page?
For example if we have a domain www.bobshardware.com.au and we setup a subdomain sydneysupplies.bobshardware.com.au and then brisbanescrewdrivers.bobshardware.com.au and used those in ad campaigns. Each subdomain being redirected back to a single page such as bobshardware.com.au/brisbane-screw-drivers etc. Is there a benefit ? Cheers

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.

No index on subdomains
Hi, We have a subdomain that is appearing in the search results - I want to hide this as it looks really bad. If I were to add the no index tag to the sub domain would URL would this affect the whole domain or just that sub domain? The main domain is vitally important - it is just that sub domain I need to hide. Many thanks

Should we move our documentation off subdomain?
Background: We have a popular open source e-commerce platform at http://spreecommerce.com. Right now the documentation is on http://guides.spreecommerce.com. We have "edge" documentation (for stuff that's not yet released) on http://edgeguides.spreecommerce.com but since it's largely duplicative we've told google not to index any of the edge stuff (via robots.txt). Question: Should we consider moving the guides under the main website under /docs or something like this? There's a ton of great content that people often read to learn more about the platform. Seems like we might be diluting our juice a bit to have it on a separate domain. WDYT?

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.

Best geotargeting strategy: Subdomains or subfolders or country specific domain
How have the relatively recent changes in how G perceives subdomains changed the best route to onsite geotargeting i.e. not building out new country specific sites on country specific and hosted domains and instead developing sub-domains or sub-folders and geo-targeting those via webmaster tools ? In other words, given the recent change in G perception, are sub-domains now a better option than a sub-folder or is there not much in it ? Also if client has a .co.uk and they want to geo-target say France, is the sub-domain/sub-folder route still an option or is the .co.uk still too UK specific, and these options would only work using a .com ? In other words can sites on country specific domains (.co.uk , .fr, .de etc etc) use sub-folders or domains to geo-target other countries or do they have no option other than to develop new country specific (domains/hosting/language) websites ? Any thoughts regarding current best practice in this regard much appreciated. I have seen last Febs WBF which covers geotargeting in depth but the way google perceives subdomains has changed since then Many Thanks Dan

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.

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)?
