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?

Do bulk 301 redirects hurt seo value?
We are working with a content based startup that needs to 301 redirect a lot of its pages to other websites. Will give you an example to help you understand. If we assume this is the startups domain and URL structure www.ourcompany.com/brand1/article What they want to do is do a 301 redirect of www.ourcompany.com/brand1/ to www.brand1.com I have never seen 301 as a problem to SEO or link juice. But in this case where all the major URLs are getting redirected to other sites i was wondering if it would have a negative effect. Right now they have just 20-30 brands but they are planning to hit a couple of hundreds this year.

Using H3 before or instead of an H2...
My designer and I have been having an argument: we have a blog with short, 400 words posts. They have an H1 with nice keywords and a catchy title, and then a few subheadings. I don't like making the subheadings H2, because the font looks way too large in Wordpress, so my designer wants to make them all H4s, so the font looks to be a nicer size. Here's my problem with that and why I usually just bold the subheadings: Is it really bad to put a bunch of H4s right under an H1, with not H2's or 3's to separate? I'm reading different arguments on the internet about this and gladly welcome more debate and/or case studies. Thank you!

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

Should we 301 redirect old events pages on a website?
We have a client that has an events category section that is filled to the brim with past events webpages. Another issue is that these old events webpages all contain duplicate meta description tags, so we are concerned that Google might be penalizing our client's website for this issue. Our client does not want to create specialized meta description tags for these old events pages. Would it be a good idea to 301 redirect these old events landing pages to the main events category page to pass off link equity & remove the duplicate meta description tag issue? This seems drastic (we even noticed that searchmarketingexpo.com is keeping their old events pages). However it seems like these old events webpages offer little value to our website visitors. Any feedback would be much appreciated.

What are the effects of having Multiple Redirects for pages under the same domain
Dear Mozers, First of all let me wish you all a Very Happy, Prosperous, Healthy, Joyous & Successful New Year ! I'm trying to analyze one of the website's Web Hosting UK Com Ltd. and during this process I've had this question running through my mind. This project has been live since the year 2003 and since then there have be changes made to the website (obviously). There have also been new pages been added, the same way some new pages have even been over-written with changes in the url structures too. Now, coming back to the question, if I've have a particular url structure in the past when the site was debuted and until date the structure has been changes thrice (for example) with a 301 redirect to every back dated structure, WOULD it impact the sites performance SEOwise ? And let's say that there's hundreds of such redirections under the same domain, don't you think that after a period of time we should remove the past pages/urls from the server ? That'd certainly increase the 404 (page not found) errors, but that can be taken care of. How sensible would it be to keep redirecting the bots from one url to the other when they only visit a site for a short stipulated time? To make it simple let me explain it with a real life scenario. Say if I was staying a place A then switched to a different location in another county say B and then to C and so on, and finally got settled at a place G. When I move from one place to another, I place a note of the next destination I'm moving to so that any courier/mail etc. can be delivered to my current whereabouts. In such a case there's a less chance that the courier would travel all the destinations to deliver the package. Similarly, when a bot visits a domain and it finds multiple redirects, don't you think that it'd loose the efficiency in crawling the site? Ofcourse, imo. the redirects are important, BUT it should be there (in htaccess) for only a period of say 3-6 months. Once the search engine bots know about the latest pages, the past pages/redirects should be removed. What are your opinions about this ?

Too many 301 redirects?
Hey, My company currently has one chief website with about 500-600 other domains that all feature the same material as the chief website. These domains have been around for about 5 years and have actually picked up some link traffic. I have all of these identical web-pages utilizing rel=canonical but I was wondering if I would be better served, from SEO purposes, to 301 redirect all of these sites to their respective pages on our chief website? If I add 500 301 redirects, will the major search engines consider this to be black-hat link-building even though the sites are related and technically already feature the same content? For an example, the chief website is www.1099pro.com and I would 301 redirect the below sites to the chief site: 1099softwarepro.com 1099softwarepro.info 1099softwarepro.net 1099softwarepro.biz 1099softwareprofessionals.com 1099softwareprofessionals.info ...you get the point

301 doesn't redirect a page that ends in %20, and others being appended with ?q=
I have a product page that ends /product-name**%20** that I'm trying to redirect in this way: Redirect 301 /products/product-name%20 http://www.site.com/products/product-name And it doesn't redirect at all. The others, those with %20, are being redirected to a url hybrid of old and new: http://www.site.com/products/product-name**?q=old-url** I'm using Drupal CMS, and it may be creating rules that counter my entries.

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
