Is it a problem to use a 301 redirect to a 404 error page, instead of serving directly a 404 page?
-
We are building URLs dynamically with apache rewrite.
When we detect that an URL is matching some valid patterns, we serve a script which then may detect that the combination of parameters in the URL does not exist. If this happens we produce a 301 redirect to another URL which serves a 404 error page,So my doubt is the following: Do I have to worry about not serving directly an 404, but redirecting (301) to a 404 page? Will this lead to the erroneous original URL staying longer in the google index than if I would serve directly a 404?
Some context. It is a site with about 200.000 web pages and we have currently 90.000 404 errors reported in webmaster tools (even though only 600 detected last month).

in webmaster tools 404 are going gradually down for desktop and now suddenly going up for mobile for pages that are not linked to for months.

I suspect you may be right.
How long ago did they appear?
Are they starting to go gradually down or up?

thanks a lot SilverDoor.
The huge number of errors, were caused by a problem with the internal site architecture several months ago which got thousdands of pages in the index that should not exist (and also have no other related relevanted pages). This architecture is fixed now. Still for some reason mobile crawler of webmaster tools is returning now suddenly lots of 404 for mobile view, which I suspect are coming from old 404 in google cache.

Hi,
You should never redirect to a 404 page.
Search Engines are going to see this as an error and may even think you are trying to manipulate users around your site.
I would redirect the pages to a relevant page on your site.
With regards to the huge number of errors now appearing, I need some more details to answer the question:
- How many 404's would you expect there to be (give an estimate)?
- How many 301 redirects do you think would have been implemented with the script?
- Have you recently changed anything else with the HTTP Status Codes?

Will 301 Redirects Slow Page Speed?
We have a lot of subdomains that we are switching to subfolders and need to 301 redirect all the pages from those subdomains to the new URL. We have over 1000 that need to be implemented. So, will 301 redirects slow the page speed regardless of which URL the user comes through? Or, as the old urls are dropped from Google's index and bypassed as the new URLs take over in the SERPs, will those redirects then have no effect on page speed? Trying to find a clear answer to this and have yet to find a good answer

301 Redirect of subdomain?
Fellow Mozzers, I'm having a hard time wrapping my brain around a redirect issue and thought it was worth posing the question to the Moz community. I did a search first but couldn't find the exact answer I was looking for. How does a 301 redirect work when you redirect a sub domain example.homepage.com to www.homepage.com but you keep the sub directories of example.homepage.com/page-1 active and are trying to rank them? I'm dealing with a current project where this is happening and this doesn't make sense to me, to redirect the subdomain if you're also trying to rank/create search traffic for pages, sub directories on example.homepage.com. This also get's into the debate of if a sub domain site is viewed as it's own website and therefore has to rank itself. If this is true, it seems like we're kind of killing the authority of the site by redirecting it. Additionally, www.homepage.com has a much stronger link profile than example.homepage.com I hope this makes sense. Any thoughts are appreciated. Thanks for your time.

Is using dots in URL path really a problem?
we have a couple of pages displaying a dot in the URL path like domain.com/mr.smith/widget-mr.smith It displays fine in chrome, firefox and IE and for the user it may actually look better than replacing it by _ or -. Did this ever cause problems to anybody?

Any statement from google about it?
Should I change existing URLs? If so, which other characters can I use in the URL instead of underscore and dash, since in our system dash and underscore are already used for rewriting other characters. Thanks0 -

How to stop Google crawling after 301 redirect?
I have removed all pages from my old website and set 301 redirect to new website. But, I have verified old website with Google webmaster tools' HTML verification file which enable me to track all data and existence of pages in Google search for my old website. I was assumed that, Google will stop crawling and DE-indexed all pages after 301 redirect. Because, I have set 301 redirect before 3 months. Now, I'm able to see Google bot activity on my website with help of Google webmaster tools. You can find out attachment to know more about it.

Can penalties be passed via 301 redirect?
I have a well established domain that's been hit with some penalties. It hasn't been nuked off the map, just downgraded, especially on short-tail, one word type queries. I'm planning on redirecting this domain to another well established domain. The domains already have a history of lots of interlinking and are very similar from a subject matter standpoint. I feel that the penalized domain has been hit with an "over-optimization" of link anchor text penalty (I'm hoping it's algorithmic, but it could be manual). My question is if anyone has ever heard of a penalty like this being transferred to another domain through a 301 redirect. My hope is that the penalty just puts a cap on how much juice the redirect can pass, rather than transferring the penalty to the other domain itself. Any thoughts on this?

NOINDEX listing pages: Page 2, Page 3... etc?
Would it be beneficial to NOINDEX category listing pages except for the first page. For example on this site: http://flyawaysimulation.com/downloads/101/fsx-missions/ Has lots of pages such as Page 2, Page 3, Page 4... etc: http://www.google.com/search?q=site%3Aflyawaysimulation.com+fsx+missions Would there be any SEO benefit of NOINDEX on these pages? Of course, FOLLOW is default, so links would still be followed and juice applied. Your thoughts and suggestions are much appreciated.
