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!!

Redirected Old Pages Still Indexed
Hello, we migrated a domain onto a new Wordpress site over a year ago. We redirected (with plugin: simple 301 redirects) all the old urls (.asp) to the corresponding new wordpress urls (non-.asp). The old pages are still indexed by Google, even though when you click on them you are redirected to the new page. Can someone tell me reasons they would still be indexed? Do you think it is hurting my rankings?

Changing URL structure of date-structured blog with 301 redirects
Howdy Moz, We've recently bought a new domain and we're looking to change over to it. We're also wanting to change our permalink structure. Right now, it's a WordPress site that uses the post date in the URL. As an example: http://blog.mydomain.com/2015/01/09/my-blog-post/ We'd like to use mod_rewrite to change this using regular expressions, to: http://newdomain.com/blog/my-blog-post/ Would this be an appropriate solution? RedirectMatch 301 /./././(.) /blog/$1

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.

Changing a parent category and 301 redirecting
I have a set of three pages that are subpages of a parent. The structure is as follows: mysite.com/directory/personal-widgets mysite.com/directory/commercial-widgets mysite.com/directory/widgets-services The partent page name "directory" really isn't working for where I want these pages to evolve. So I want to change it to "guides" In a world without worrying about google, I would simply change the parent page to guides, so they look like this, and be done with it: mysite.com/guides/personal-widgets But, the obvious problem is that I have external links to the page now. And the pages have a nice PR. And they also have Facebook page Likes and I don't know if I'll lose those. I know that if I should do this I should redirect the pages to the new pages of course. My question is: Will redirecting the old URL to the new URL with a 301 cause anything negative to happen that I might not be expecting? Does Google dislike Redirects for any reason, or understand they are sometimes necessary?

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?

NOINDEX listing pages: Page 2, Page 3... etc?
Would it be beneficial to NOINDEX category listing pages except for the first page. For example on this site: http://flyawaysimulation.com/downloads/101/fsx-missions/ Has lots of pages such as Page 2, Page 3, Page 4... etc: http://www.google.com/search?q=site%3Aflyawaysimulation.com+fsx+missions Would there be any SEO benefit of NOINDEX on these pages? Of course, FOLLOW is default, so links would still be followed and juice applied. Your thoughts and suggestions are much appreciated.

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
