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 Redirect in breadcrumb. How bad is it?
Hi all, How bad is it to have a link in the breadcrumb that 301 redirects? We had to create some hidden category pages in our ecommerce platform bigcommerce to create a display on our category pages in a certain format. Though whilst the category page was set to not visable in bigcommerce admin the URL still showed in the live site bread crumb. SO, we set a 301 redirect on it so it didnt produce a 404. However we have lost a lot of SEO ground the past few months. could this be why? is it bad to have a 301 redirect in the breadrcrumb.

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.

SEO impact of 301 redirects based on IP addresses from a specific state
Hello Moz Community! We are facing an issue that may or may not be unique, but need some advice and/or clarification on the best way to address the issue. We recently rebranded and launched a new site under a new domain and things have been progressing well. However, despite all the up front legwork on trademarks and licensing, we have recently encountered a hiccup that forces us to revert to the old URL/branding for one specific state. This may be a temporary issue that lasts a couple of months or it could potentially be in the court system for a couple of years. One potential solution we have discussed is to redirect the new site to the old site based on IP addresses for the state in question. Looking for any guidance on what type of impact this may have on SEO. Also open to any other suggestions or guidance on dealing with this situation. Thanks

Website Redesign, 301 Redirects, and Link Juice
I want to change my client’s ecommerce site to Shopify. The only problem is that Shopify doesn’t let you customize domains. I plan to: keep each page’s content exactly the same keep the same domain name 301 redirect all of the pages to their new url The ONLY thing that will change is each page’s url. Again, each page will have the exact same content. The only source of traffic to this site is via Google organic search and sales depend on the traffic. There are about 10 pages that have excellent link juice, 20 pages that have medium link juice, and the rest is small link juice. Many of our links that have significant link juice are on message boards written by people that like our product. I plan to change these urls and 301 redirect them to their new urls. I’ve read tons of pages online about this topic. Some people that say it won’t effect link juice at all, some say it will might effect link juice temporarily, and others are uncertain. Most answers tend to be “You should be good. You might lose some traffic temporarily. You might want to switch some of your urls to the new structure to see how it affects it first.” Here’s my question: 1) Has anyone ever done changed a url structure for an existing website with link juice? What were your results and do you have a definitive answer on the topic? 2) How much link juice (if any) will be lost if I keep all of the exact content the same but only change each page’s url? 3) If link juice is temporarily lost and then regained, how long will it be temporarily lost? 1 week? 1 month? 6 months? Thanks.

How to 301 redirect old wordpress category?
Hi All, In order to avoid duplication errors we've decided to redirect old categories (merge some categories).
Intermediate & Advanced SEO | | BeytzNet
In the past we have been very generous with the number of categories we assigned each post. One category needs to be redirected back to blog home (removed completely) while a couple others should be merged. Afterwords we will re-categorize some of the old posts. What is the proper way to do so?
We are not technical, Is there a plugin that can assist? Thanks0 -
Can penalties be passed via 301 redirect?
I have a well established domain that's been hit with some penalties. It hasn't been nuked off the map, just downgraded, especially on short-tail, one word type queries. I'm planning on redirecting this domain to another well established domain. The domains already have a history of lots of interlinking and are very similar from a subject matter standpoint. I feel that the penalized domain has been hit with an "over-optimization" of link anchor text penalty (I'm hoping it's algorithmic, but it could be manual). My question is if anyone has ever heard of a penalty like this being transferred to another domain through a 301 redirect. My hope is that the penalty just puts a cap on how much juice the redirect can pass, rather than transferring the penalty to the other domain itself. Any thoughts on this?

301 - should I redirect entire domain or page for page?
Hi, We recently enabled a 301 on our domain from our old website to our new website. On the advice of fellow mozzer's we copied the old site exactly to the new domain, then did the 301 so that the sites are identical. Question is, should we be doing the 301 as a whole domain redirect, i.e. www.oldsite.com is now > www.newsite.com, or individually setting each page, i.e. www.oldsite.com/page1 is now www.newsite.com/page1 etc for each page in our site? Remembering that both old and new sites (for now) are identical copies. Also we set the 301 about 5 days ago and have verified its working but haven't seen a single change in rank either from the old site or new - is this because Google hasn't likely re-indexed yet? Thanks, Anthony

Any way to find which domains are 301 redirected to competitors' websites?
By looking at the work from an SEO collegue it became clear that his weak linkbuilding graph probably is not the cause for his good rankings for a pretty competitive keyword. (also no social mentions where found) I was wondering what it could be, site structure and other on page optimization factors seems to be ok and I don't think there will be exceptionally good or bad user behavior... Finally I looked at the competitors and found that they have more links, better content en better design, so I got a little stuck. The only reason I can think of is that he is doing 301 redirects (or is rel=canonical tags). Is there a way to trace these redirects back to the source in order to include this important variable in your competitor research? thnx
