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 hops from non-https and www
It's best practice to minimize the amount of 301 redirect hops. Ideally only one redirect hop. It's also best practice to 301 redirect (or at least canonical) your non-https and/or your non-www (or www) to the canonical protocol/subdomain. The simplest (and possibly the most common) way to implement canonical protocol/subdomain redirects is through a load balancer or before your app processes the request. Both of which will just blanket 301 to the canonical domain/protocol regardless if the path exists or not In which case, you could have: Two hops. i.e. hop #1 http://example.com/foo to https://example.com/foo, hop #2 https://example.com/foo to https://example.com/bar 301 to a 404. Let's say https://example.com/dog never existed, but somebody for whatever reason linked to it (maybe a typo). If I request https://www.example.com/dog, the load balancer would 301 to a 404 page. Either scenario above should be fairly rare. However, you can't control how people link to you. Should I care about either above scenario? I could have my app attempt to check if the page exists before forwarding, but that code could be complicated.

Redirecting homepage to internal page (2nd Tier page)
We are planning to experiment redirecting our homepage to one of the 2nd tier page. I mean....example.com to example.com/page. We need this page to rank well, but it doesn't have much internal links or external back-links, so we opt for this redirect. Advantage with this page is, it has "keyword" we want to rank for in URL. "page" in example.com/page. Will this help or hurt us in SEO? I think we are missing keyword in our root domain, so interested to highlight this page. Thanks, Satish

Multilingual Site and 301 redirection
Hey there awesome people of Moz I have this site that has many languages in it. The main language is English and my developer did the following www.example.com ( is the main site ) which redirects with a 301 to www.example.com/en if your geo location is supported by our languages then you will automatically be redirected to whatever language you have in your country but does the first language with is english have to 301 redirect to www.example.com/en ? I thought that the right way is to just leave /en at the root file. Thanks in advance

How long is it safe to use a 302 redirect?
Hi All, Lets assume there is site A and site B, both sites are live on the internet today as standalone businesses, but they sell very similar products. Site B has built up some link equity and will eventually become the domain for site A due to an organisational re-brand. For the time being however site A will remain, but site B needs to disappear temporarily, but not lose the link equity which has been built up against it. My current thinking is to 302 redirect site B to site A such that users and search bots accessing site B will be redirected to site A whilst leaving the link equity that exists against site B fully intact and allowing us to continue to grow it should we wish to. The question is, does anybody have a view on how long it is safe to use a 302 temporary redirect for? i.e., is 8-10 months to long. Thanks, Ben
