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

Yes Nikki, great addition about avoiding redirect chains! Redirects are useful and difficult to avoid in most cases but redirecting to a redirect should always be avoided for the sake of Page Speed and common sense
Cheers!! -
Hi, like what Bryan said, it's better if you could avoid having redirects. Because of the extra step, redirects can affect your PageSpeed. We've always used redirects however - it's difficult to avoid - and it's very rarely flagged as a major issue when running the site in Google PageSpeed Insights and GTmetrix. The one thing we found that really has an impact on PageSpeed is a redirect chain, which should be avoided. This happens when a redirect goes to another redirect. Example: non-www redirected to a www version of the site, and then later on redirected again to an https www version. PageSpeed sites flag this as an issue, and so does Moz.
Hope this helps!

Hey Corp Analytics!
In short...
If you can avoid redirects you will certainly be serving your content faster.
Google recommends avoiding them where possible: https://developers.google.com/speed/docs/insights/mobile
"Have you ever asked where a bathroom is and when you go there you are told that this bathroom is closed and you have to go to some other bathroom? It is like that. Redirects cause your pages to load slower because it is a waste of time to go to one place just to be redirected to another."
Makes sense, right?
Here another great article on the topic and the source of that quote: https://varvy.com/pagespeed/minimize-redirects.html
Hope that helps!!

301 Redirecting from domain to subdomain
We're taking on a redesign of our corporate site on our main domain. We also have a number of well established, product based subdomains. There are a number of content pages that currently live on the corporate site that rank well, and bring in a great deal of traffic, though we are considering placing 301 redirects in place to point that traffic to the appropriate pages on the subdomains. If redirected correctly, can we expect the SEO value of the content pages currently living on the corporate site to transfer to the subdomains, or will we be negatively impacting our SEO by transferring this content from one domain to multiple subdomains?

Does removal of internal redirects(301) help in SEO
I am planning to completely remove 301 redirects manually by replacing such links with actual live pages/links. So there will be no redirects internally in the website. Will this boost our SEO efforts? Auto redirects will be there for incoming links to non-existing pages. Thanks, Satish

Images Returning 404 Error Codes. 301 Redirects?
We're working with a site that has gone through a lot of changes over the years - ownership, complete site redesigns, different platforms, etc. - and we are finding that there are both a lot of pages and individual images that are returning 404 error codes in the Moz crawls. We're doing 301 redirects for the pages, but what would the best course of action be for the images? The images obviously don't exist on the site anymore and are therefore returning the 404 error codes. Should we do a 301 redirect to another similar image that is on the site now or redirect the images to an actual page? Or is there another solution that I'm not considering (besides doing nothing)? We'll go through the site to make sure that there aren't any pages within the site that are still linking to those images, which is probably where the 404 errors are coming from. Based on feedback below it sounds like once we do that, leaving them alone is a good option.

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.
Intermediate & Advanced SEO | | lcourse
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).0 -
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 ?

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.
