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.

No, doing this at bulk shouldn't necessarily hurt them when you make sure that you're doing it the right way with the proper redirects in place. In the end, you see tons of sites that are going out of business or change domain names and move the data over to a new domain. So that's why your bulk action isn't such a big problem.

Is domain authority lost if you create a 301 redirect but mark it as noindex, nofollow?
Hi everyone, Our company sells products in various divisions. While we've been selling Product A and Product B under our original brand, we've recently created a new division with a new domain to focus on a Product B. The new domain has virtually no domain authority (3) while the original domain has some (37). We want customers to arrive on the new domain when they search for key search terms related to Product B instead of the pages that previously existed on our main website. If we create 301 redirects for the pages and content on the main site and add noindex, nofollow tags, will we lose the domain authority that we have from our original domain because the pages now have the noindex, nofollow tags? I read a few blog posts from Moz that said there isn't any domain authority lost with 301 redirects but I'm not sure if that is true if the pages are noindex, nonofollow. Do you follow? 🙂 Apologies for the lengthy post. Love this community and the great Moz team. Thanks, Joe

How to handle potentially thousands (50k+) of 301 redirects following a major site replacement
We are looking for the very best way of handling potentially thousands (50k+) of 301 redirects following
Intermediate & Advanced SEO | | GeezerG
a major site replacement and I mean total replacement. Things you should know
Existing domain has 17 years history with Google but rankings have suffered over the past year and yes we know why. (and the bitch is we paid a good sized SEO company for that ineffective and destructive work)
The URL structure of the new site is completely different and SEO friendly URL's rule. This means that there will be many thousands of historical URL's (mainly dynamic ones) that will attract 404 errors as they will not exist anymore. Most are product profile pages and the God Google has indexed them all. There are also many links to them out there.
The new site is fully SEO optimised and is passing all tests so far - however there is a way to go yet. So here are my thoughts on the possible ways of meeting our need,
1: Create 301 redirects for each an every page in the .htaccess file that would be one huge .htaccess file 50,000 lines plus - I am worried about effect on site speed.
2: Create 301 redirects for each and every unused folder, and wildcard the file names, this would be a single redirect for each file in each folder to a single redirect page
so the 404 issue is overcome but the user doesn't open the precise page they are after.
3: Write some code to create a hard copy 301 index.php file for each and every folder that is to be replaced.
4: Write code to create a hard copy 301 .php file for each and every page that is to be replaced.
5: We could just let the pages all die and list them with Google to advise of their death.
6: We could have the redirect managed by a database rather than .htaccess or single redirect files. Probably the most challenging thing will be to load the data in the first place, but I assume this could be done programatically - especially if the new URL can be inferred from the old. Many be I am missing another, simpler approach - please discuss0 -
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

301 redirect subdirectory to new domain
I'm planning on using 301 redirects to spin out a subdirectory of my current website to be its own separate domain. For instance, I currently have a website www.website.com and my writers write tech news at www.website.com/news. Now I want to 301 redirect www.website.com/news to www.technews.com. Will this have any negative impact on SEO? What are some steps that I can take to minimize these impacts?

SEO value in multiple backlinks from same domain and from various sub-domains.
A site has a link to my site as one of their main tabs, which means whenever a user clicks through to another page within the site, my link - being a main tab - is there. This creates thousands of links from this site. How does Google treat this? Do we have a rough formula estimate. In other words, assume it creates 1,000 backlinks would the SEO value be around the same as if I had just 2 link total as a main tab, but on 2 different non-related sites? Or, does it actually count fully as 1,000 links? Links from various sub-domains. Several .EDU's are linking to my site. Different schools within the overall same university. Example: nursing.abc.edu links to my site, but so does business.abc.edu. For SEO does that count as much as if I had links from complete non-related universities, or would Google evaluate that these links are related (since same main domain) and that will discount any links more than 1 to some extent? If discounted, then what do we estimate the discount to be? thank yoyu

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?

Iframe redirect bad for SEO?
Hi, I have a website (http://www.blowingminds.de) wich I put a spreadshirt shop into via iframe. The thing is I am not sure on how the iframe effects my SEO? Can I just optimise the main domain for search? Well I want the spreadshirt shop to be found under the domain name (www.blowingminds.de) but the only real way to do it is by implementing an iframe because each spreadshirt shop has its own subdomain eg.: blowingminds.spreadshirt.de but the only real way to do it is via iframe, as they do not offer a complete domain redirect. (Or have I overseen some other way?) I hope you guys can help me on this one 🙂 Thanks in advance. Malte

How To 301 Redirect .html pages
I need to redirect a page/URL that is purely .html to a new location. I don't know how to do this. All the redirects I can find are for server side code pages .php/.aspx etc. From my understanding I can't put a server side redirect in a .html file. I am hosting on a microsoft server, however the new page I am redirecting to is .php. I am running some WordPress (.php) files on the server. I need to make it redirect before the old page loads so visitors don't start reading something that is about to get redirected Can someone please help me?
