301 redirects
-
One of our employees took an SEO class recently. She was told that having too many 301 redirects can hurt SEO. I have never heard of 301 redirects as having a negative impact. Any thoughts?
-
Load time isn't that much, same domain redirects only take 16-25ms. I would be more concerned with cross domain redirects.
-
I would also be concerned with load time and the effect it can have on user experience and bounces back into the serps.

There is no limit to the number of redirects that Google is willing to crawl within a site. However, there's a limit to the number of redirect chains that they'll crawl. A redirect chain is when one page redirects to a page that redirects to a page that redirects ... and so on.
-
It can have a negative impact if you have redirect chains. Matt Cutts discusses 301 redirects and their impact.
-
Having too many 301 redirects in a chain can have a non-positive impact. I.e. Don't 301 a page to another page that 301s to another page that 301s to another page, etc. etc. etc. Google once stated they could do 5 pages in a 301 chain before giving up. But honestly, why would you choose to redirect to a redirecting page when you could point it at something much more relevant? But as for having a bulk of 301s, I wouldn't worry. If you had 300 different pages that were all being redirected to 300 other pages, google would not devalue you for it. If your redirects are relevant and are good for the user experience, then you're fine.

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.

301 Redirect / Canonical loop on home page?
Hi there, My client just launched a new site and the CMS requires that the home page goes to a subfolder - clientsite.com/store. Currently there is a redirect in place such that clientsite.com -> clientsite.com/store. However, I want clientsite.com to be the canonical version of the URL. What should I do in this case, given that there is now a loop between the redirected page and the canonical page?

301 vs 302
We recently launched a redesign and I noticed from running a crawl using Screaming Frog SEO that our redirects are all being seen as 302. I know 302 is a temporary redirect, but does this hurt SEO rankings when all our redirects are being seen as 302s instead of 301s? Also, the way I implemented the redirects was by using the IIS Manager Tool. Is it possible that our IIS Manager Tool is not configured properly and instead of adding the redirect as 301, it is inserting it into the rewrite file as 302s?

301 entire site
Is there a good 301 code snippet to change just the root domain but keep the ending extensions? I just bid on a domain that I think would be much better for me moving forward, but do not want to have to try going through thousands of pages to do their 301 individually My site is almost 4 yrs old. Well established and has a large fanbase. Several of our social networks are under the name of the new branded domain, hence part of the desire to switch.

301 redirect hell.... How do you de-commission an old site
Hi SEO experts: We operate a vacation rental website and around 1 year ago moved to a different platform. Because our pages are arranged by location (what we refer to as Locales) we need to put 301 redirects for all the old locale pages. So for example: www.example.com/__Skeggness.cfm redirects to www.example/com/vacation-rentals/locale/skeggness But here's the problem: We can't seem to get Google to drop those old __{locale_name}.cfm pages... even after over 12-months of the new site going live! Other clues we've noticed: The old underscore URLs show up in our SERP sub-links Sometimes google shows the new page title and description but attributes it to the __{locale_name}.cfm URL (aghh!!!) One suggestion we received was to use the URL removal tool in Google WMT.... But given we have 1,000's of locales i don't see that as being affective. Questions: Any suggestions on how to get Google to drop these old URLs and use the new ones? Is this situation hurting our SEO? Or do you think its benign... and I should just take a deep breath.... and relax at little more...

How to stop Google crawling after 301 redirect?
I have removed all pages from my old website and set 301 redirect to new website. But, I have verified old website with Google webmaster tools' HTML verification file which enable me to track all data and existence of pages in Google search for my old website.

Duplicate content even with 301 redirects
I know this isn't a developer forum but I figure someone will know the answer to this. My site is http://www.stadriemblems.com and I have a 301 redirect in my .htaccess file to redirect all non-www to www and it works great. But SEOmoz seems to think this doesn't apply to my blog, which is located at http://www.stadriemblems.com/blog It doesn't seem to make sense that I'd need to place code in every .htaccess file of every sub-folder. If I do, what code can I use? The weirdest part about this is that the redirecting works just fine; it's just SEOmoz's crawler that doesn't seem to be with the program here. Does this happen to you?
