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!!

Google Is Indexing my 301 Redirects to Other sites
Long story but now i have a few links from my site 301 redirecting to youtube videos or eCommerce stores. They carry a considerable amount of traffic that i benefit from so i can't take them down, and that traffic is people from other websites, so basically i have backlinks from places that i don't own, to my redirect urls (Ex. http://example.com/redirect) My problem is that google is indexing them and doesn't let them go, i have tried blocking that url from robots.txt but google is still indexing it uncrawled, i have also tried allowing google to crawl it and adding noindex from robots.txt, i have tried removing it from GWT but it pops back again after a few days. Any ideas? Thanks!

New Site (redesign) Launched Without 301 Redirects to New Pages - Too Late to Add Redirects?
We recently launched a redesign/redevelopment of a site but failed to put 301 redirects in place for the old URL's. It's been about 2 months. Is it too late to even bother worrying about it at this point? The site has seen a notable decrease in site traffic/visits, perhaps due to this issue. I assume that once the search engines get an error on a URL, it will remove it from displaying in search results after a period of time. I'm just not sure if they will try to re-crawl those old URLs at some point and if so, it may be worth it to have those 301 redirects in place. 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

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

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 -
Multiple 301 redirects for a HTTPS URL. Good or bad?
I'm working on an ecommerce website that has a few snags and issues with it's coding. They're using https, and when you access the website through domain.com, theres a 301 redirect to http://www.domain.com and then this, in turn, redirected to https://www.domain.com. Would this have a deterimental effect or is that considered the best way to do it. Have the website redirect to http and then all http access is redirected to the https URL? Thanks

Merging Sites: Will redirecting the old homepage to an internal page on the new site cause issues?
I've ended up with two sites which have similar content (but not duplicate) and target similar keywords, rather than trying to maintain two sites I would like to merge the sites together. The old site is more of a traditional niche site and targets a particular set of keywords on its homepage, the new site is more of an authority site with a magazine type homepage and targets the same set of keywords from an internal page. My question is: Should I redirect the old site's homepage to the relevant internal page on the new website...
Intermediate & Advanced SEO | | lara_dar
...or should I redirect the old site's homepage to the new site's homepage? (the old site's homepage backlinks are a mixture of partial match keyword anchor text, naked URLs and branded anchor text) I am in two minds (a & b!) (a) Redirecting to the internal page would be great for ranking as there are some decent backlinks and the content is similar (b) But usually when you do a 301 redirect the homepage usually directs to the new homepage and some of the old site's links are related to the domain rather than the keyword (e.g. http://www.site.com) and some people will be looking for the site's homepage. What do you think? Your help is much appreciated (and hope this makes sense...!)0
