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?

When should you 410 pages instead of 404
Hi All, We have approx 6,000 - 404 pages. These are for categories etc we don't do anymore and there is not near replacement etc so basically no reason or benefit to have them at all. I can see in GWT , these are still being crawled/found and therefore taking up crawler bandwidth. Our SEO agency said we should 410 these pages?.. I am wondering what the difference is and how google treats them differently ?. Do anyone know When should you 410 pages instead of 404 ? thanks Pete

Is a 404, then a meta refresh 301 to the home page OK for SEO?
Hi Mozzers I have a client that had a lot of soft 404s that we wanted to tidy up. Basically everything was going to the homepage. I recommended they implement proper 404s with a custom 404 page, and 301 any that really should be redirected to another page. What they have actually done is implemented a 404 (without the custom 404 page) and then after a short delay 301 redirected to the homepage. I understand why they want to do this as they don't want to lose the traffic, but is this a problem with SEO and the index? Or will Google treat as a hard 404 anyway? Many thanks

Geoip redirection, 301 or 302?
Hello all Let me first try to explain what our company does and what it is trying to achieve. Our company has an online store, sells products for 3 different countries, and two languages for each country. Currently we have one site, which is open to all countries, what we are trying to achieve is make 3 different stores for these 3 different countries, so we can have a better control over the prices in each country. We are going to use Geoip to redirect the user to the local store in his country. The suggested new structure is to add sub-folders as following: www.example.com/ca-en
Intermediate & Advanced SEO | | ajarad
www.example.com/ca-fr
www.example.com/us-en
... If a visitor is located outside these 3 countries, then she'll be redirected to the root directory www.example.com/en We can't offer to expand our SEO team to optimize new pages for the local market, it's not the priority for now, the main objective now is to be able to control the prices for different market. so to eliminate the duplicate issue, we'll use canonical tags. Now knowing our objective from the new URL structure, I have two questions: 1- which redirect should we use? 301, 302?
If we choose 301, then which version of the site will get the link juice? (i.e, /ca-en or /us-en?)
if we choose 302, then will the link juice remain in the original links? is it healthy to use 302 for long term redirections? 2- Knowing that Google bots comes from US-IP, does that mean that the other versions of the site won't be crawled (i.e, www.example.com/ca-fr), this is especially important for us as we are using AdWords, and unindexed pages will effect our quality score badly. I'd like to know if you have other account structure in your mind that would be better than this proposed structure. Your help is highly highly appreciated.
Thanks in advance.0 -
Do search engines crawl links on 404 pages?
I'm currently in the process of redesigning my site's 404 page. I know there's all sorts of best practices from UX standpoint but what about search engines? Since these pages are roadblocks in the crawl process, I was wondering if there's a way to help the search engine continue its crawl. Does putting links to "recent posts" or something along those lines allow the bot to continue on its way or does the crawl stop at that point because the 404 HTTP status code is thrown in the header response?

DNS or 301 Website Redirect
We are running a marketplace site, so we have thousands of vendors selling their products on our site. Each vendor has a Profile page and we are soon to launch a premium store-front that is white label. Many of these vendors will want to point a custom url to their premium store-front (which is a sub domain of the marketplace) and we are trying to get an understanding of how we should instruct them to point their url in a way that will give the main marketplace site the seo juice. We also want to understand what will show up in the address bar. Will it be their url or our sub domain? Will any of the marketplace seo juice boost their url local listing status?

Are there any negative effects to using a 301 redirect from a page to another internal page?
For example, from http://www.dog.com/toys to http://www.dog.com/chew-toys. In my situation, the main purpose of the 301 redirect is to replace the page with a new internal page that has a better optimized URL. This will be executed across multiple pages (about 20). None of these pages hold any search rankings but do carry a decent amount of page authority.

How To 301 Redirect .html pages
I need to redirect a page/URL that is purely .html to a new location. I don't know how to do this. All the redirects I can find are for server side code pages .php/.aspx etc. From my understanding I can't put a server side redirect in a .html file. I am hosting on a microsoft server, however the new page I am redirecting to is .php. I am running some WordPress (.php) files on the server. I need to make it redirect before the old page loads so visitors don't start reading something that is about to get redirected Can someone please help me?

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
