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?

Using a Reverse Proxy and 301 redirect to appear Sub Domain as Sub Directory - what are the SEO Risks?
We’re in process to move WordPress blog URLs from subdomains to sub-directory. We aren’t moving blog physically, but using reverse proxy and 301 redirection to do this. Blog subdomain URL is https://blog.example.com/ and destination sub-directory URL is https://www.example.com/blog/ Our main website is e-commerce marketplace which is YMYL site. This is on Windows server. Due to technical reasons, we can’t physically move our WordPress blog to the main website. Following is our Technical Setup Setup a reverse proxy at https://www.example.com/blog/ pointing to https://blog.example.com/ Use a 301 redirection from https://blog.example.com/ to https://www.example.com/blog/ with an exception if a traffic is coming from main WWW domain then it won’t redirect. Thus, we can eliminate infinite loop. Change all absolute URLs to relative URLs on blog Change the sitemap URL from https://blog.example.com/sitemap.xml to https://www.example.com/blog/sitemap.xml and update all URLs mentioned within the sitemap. SEO Risk Evaluation We have individual GA Tracking ID and individual Google Search Console Properties for main website and blog. We will not merge them. Keep them separate as they are. Keeping this in mind, I am evaluating SEO Risks factors Right now when we receive traffic from main website to blog (or vice versa) then it is considered as referral traffic and new cookies are set for Google Analytics. What’s going to happen when its on the same domain? Which type of settings change should I do in Blog’s Google Search Console? (A). Do I need to request “Change of Address” in the Blog’s search console property? (B). Should I re-submit the sitemap? Do I need to re-submit the blog sitemap from the https://www.example.com/ Google Search Console Property? Main website is e-commerce marketplace which is YMYL website, and blog is all about content. So does that impact SEO? Will this dilute SEO link juice or impact on the main website ranking because following are the key SEO Metrices. (A). Main website’s Avg Session Duration is about 10 minutes and bounce rate is around 30% (B). Blog’s Avg Session Duration is 33 seconds and bounce rate is over 92%

301 Redirect - Rank Recovery Examples?
Hi All, I recently did a 301 redirect. Page to Page and the notified google via its console. Its been 6 days since. The home page and one other high traffic page swopped out with the new domain on google search index with 3-4 drops in ranking for each. The rest of the sites pages have been indexed but still reflect the old domain when searched. Recently today my home page dropped even further to the second page of google index for the specific keyword. Can you share similar experiences and how long it took you to recover rank fully? and how long for all pages to swop out on google search's index? Regards Mike

301 Redirect Showing Up as Thousands Of Backlinks?
Hi Everyone, I'm currently doing quite a large back link audit on my company's website and there's one thing that's bugging me. Our website used to be split into two domains for separate areas of the business but since we have merged them together into one domain and have 301 redirected the old domain the the main one. But now, both GWT and Majestic are telling me that I've got 12,000 backlinks from that domain? This domain didn't even have 12,000 pages when it was live and I only did specific 301 redirects (ie. for specific URL's and not an overall domain level 301 redirect) for about 50 of the URL's with all the rest being redirected to the homepage. Therefore I'm quite confused about why its showing up as so many backlinks - Old redirects I've done don't usually show as a backlink at all. UPDATE: I've got some more info on the specific back links. But now my question is - is having this many backlinks/redirects from a single domain going to be viewed negatively in Google's eyes? I'm currently doing a reconsideration request and would look to try and fix this issue if having so many backlinks from a single domain would be against Google's guidelines. Does anybody have any ideas? Probably somthing very obvious. Thanks! Sam

How do you 301 redirect URLs with a hashbang (#!) format? We just lost a ton of pagerank because we thought javascript redirect was the only way! But other sites have been able to do this – examples and details inside
Hi Moz, Here's more info on our problem, and thanks for reading! We’re trying to Create 301 redirects for 44 pages on site.com. We’re having trouble 301 redirecting these pages, possibly because they are AJAX and have hashbangs in the URLs. These are locations pages. The old locations URLs are in the following format: www.site.com/locations/#!new-york and the new URLs that we want to redirect to are in this format: www.site.com/locations/new-york We have not been able to create these redirects using Yoast WordPress SEO plugin v.1.5.3.2. The CMS is WordPress version 3.9.1 The reason we want to 301 redirect these pages is because we have created new pages to replace them, and we want to pass pagerank from the old pages to the new. A 301 redirect is the ideal way to pass pagerank. Examples of pages that are able to 301 redirect hashbang URLs include http://www.sherrilltree.com/Saddles#!Saddles and https://twitter.com/#!RobOusbey.

Generating 404 Errors but the Pages Exist
Hey I have recently come across an issue with several of a sites urls being seen as a 404 by bots such as Xenu, SEOMoz, Google Web Tools etc. The funny thing is, the pages exist and display fine. This happens on many of the pages which use the Modx CMS, but the index is fine. The wordpress blog in /blog/ all works fine. The only thing I can think of is that I have a conflict in the htaccess, but troubleshooting this is difficult, any tool I have found online seem useless. Have tried to rollback to previous versions but still does not work. Anyone had any experience of similar issues? Many thanks K.
