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!!

Would You Redirect a Page if the Parent Page was Redirected?
Hi everyone! Let's use this as an example URL: https://www.example.com/marvel/avengers/hulk/ We have done a 301 redirect for the "Avengers" page to another page on the site. Sibling pages of the "Hulk" page live off "marvel" now (ex: /marvel/thor/ and /marvel/iron-man/). Is there any benefit in doing a 301 for the "Hulk" page to live at /marvel/hulk/ like it's sibling pages? Is there any harm long-term in leaving the "Hulk" page under a permanently redirected page? Thank you! Matt

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!

How will changing my website's page content affect SEO?
Our company is looking to update the content on our existing web pages and I am curious what the best way to roll out these changes are in order to maintain good SEO rankings for certain pages. The infrastructure of the site will not be modified except for maybe adding a couple new pages, but existing domains will stay the same. If the domains are staying the same does it really matter if I just updated 1 page every week or so, versus updating them all at once? Just looking for some insight into how freshening up the content on the back end pages could potentially hurt SEO rankings initially. Thanks!

301 or 302 Redirects to Mobile Site
When it's detected that a mobile device is accessing the site it has the ability to redirect from www.example.com to m.example.com. Does it make more sense to employ a 301 or 302 redirect here? Google says a 301 but does not explain why (although usually I stick to "when in doubt, 301") . It seems like a 302 would prevent passing link juice to the mobile site and having mobile-optimized results also showing up in Google's index. What is the preference here?

Is it ok to use both 301 redirect and rel="canonical' at the same time?
Hi everyone, I'm sorry if this has been asked before. I just wasn't able to find a response in previous questions. To fix the problems in our website regarding duplication I have the possibility to set up 301's and, at the same time, modify our CMS so that it automatically sets a rel="canonical" tag for every page that is generated. Would it be a problem to have both methods set up? Is it a problem to have a on a page that is redirecting to another one? Is it advisable to have a rel="canonical" tag on every single page? Thanks for reading!

301 Redirects After Company Acquisition
We recently acquired a company, and now we are going to redirect all of the pages on their site to their respective pages on our site. Do we need to keep the original pages on their site active? For how long? Ideally, we would like to redirect everything and remove the old site entirely so we don't have to pay to keep hosting it. Is this possible? Thanks!

301 redirect from .html to non .html?
Previously our site was using this as our URL structure: www.site.com/page.html. A few months ago we updated our URL structure to this: www.site.com/page & we're not using the .html. I've read over this guide & don't see anywhere that discusses this: http://www.seomoz.org/learn-seo/redirection. I've currently got a programmer looking into, but am always a bit weary with their workarounds, as I'd previously had them cause more problems then fix it. Here is the solution he is looking to do: The way that I am doing the redirect is fine. The problem is of where to put the code. The issue is that the files are .html files that need to be redirected to the same url with out a .html on them. I can see if I can add that to the 404 redirect page if there is one inside of there and see if that does the trick. That way if there is no page that exists without the .html then it will still be a 404 page. However if it is there then it will work as normal. I will see what I can find and get back. Any help would be greatly appreciated. Thanks, BJ
