Do 301 redirects now allow most of the bad value to pass through?
-
I heard after the 3.2 update that most of your bad history passes though the 301 redirect.. What do you guys think out there?

Hi Matthew,
Excellent question, and one we should explore in more depth, research and write a blog post here at SEOmoz.
But the short answer is: yes. I've seen a lot of evidence in the past year that low quality backlinks pass through 301 redirects, almost as powerful as if you linked those bad links directly to the new domain.
We've seen more evidence of this lately, as Google cracks down harder on bad links, more webmasters are grumbling that that their 301s are hurting them.
Of course, the best solution to any bad redirected backlinks is to stop the 301. I've seen sites recover after doing this and heard evidence from other webmasters of this working, at least to a degree, in some situations.
Hope this helps. Best of luck with your SEO!

That is correct a 301 Redirect pushes all existing link equity to the new url structure. in order to prevent bad link equity to push through, do not 301 an old url to the new url.

Resolving 301 Redirect Chains from Different URL Versions (http, https, www, non-www)
Hi all, Our website has undergone both a redesign (with new URLs) and a migration to HTTPS in recent years. I'm having difficulties ensuring all URLs redirect to the correct version all the while preventing redirect chains. Right now everything is redirecting to the correct version but it usually takes up to two redirects to make this happen. See below for an example. How do I go about addressing this, or is this not even something I should concern myself with? Redirects (2) <colgroup><col width="123"><col width="302"></colgroup>

| Redirect Type | URL |
| | http://www.theyoungfirm.com/blog/2009/index.html 301 | https://theyoungfirm.com/blog/2009/index.html 301 | https://theyoungfirm.com/blog/ | This code below was what we added to our htaccess file. Prior to adding this, the various subdomain versions (www, non-www, http, etc.) were not redirecting properly. But ever since we added it, it's now created these additional URLs (see bolded URL above) as a middle step before resolving to the correct URL. RewriteEngine on RewriteCond %{HTTP_HOST} ^www.(.*)$ [NC] RewriteRule ^(.*)$ https://%1/$1 [R=301,L] RewriteCond %{HTTPS} !on RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L] Your feedback is much appreciated. Thanks in advance for your help. Sincerely, Bethany0 -
404 Errors for Form Generated Pages - No index, no follow or 301 redirect
Hi there I wonder if someone can help me out and provide the best solution for a problem with form generated pages. I have blocked the search results pages from being indexed by using the 'no index' tag, and I wondered if I should take this approach for the following pages. I have seen a huge increase in 404 errors since the new site structure and forms being filled in. This is because every time a form is filled in, this generates a new page, which only Google Search Console is reporting as a 404. Whilst some 404's can be explained and resolved, I wondered what is best to prevent Google from crawling these pages, like this: mydomain.com/webapp/wcs/stores/servlet/TopCategoriesDisplay?langId=-1&storeId=90&catalogId=1008&homePage=Y Implement 301 redirect using rules, which will mean that all these pages will redirect to the homepage. Whilst in theory this will protect any linked to pages, it does not resolve this issue of why GSC is recording as 404's in the first place. Also could come across to Google as 100,000+ redirected links, which might look spammy. Place No index tag on these pages too, so they will not get picked up, in the same way the search result pages are not being indexed. Block in robots - this will prevent any 'result' pages being crawled, which will improve the crawl time currently being taken up. However, I'm not entirely sure if the block will be possible? I would need to block anything after the domain/webapp/wcs/stores/servlet/TopCategoriesDisplay?. Hopefully this is possible? The no index tag will take time to set up, as needs to be scheduled in with development team, but the robots.txt will be an quicker fix as this can be done in GSC. I really appreciate any feedback on this one. Many thanks

Redirect a 301 Redirect
Does any link juice get passed from a permanent redirect to a new 301 redirect? If so, are there any studies which indicate an estimated percentage?

Can a 307 Redirect Pass on a Manual Google Link Penalty?
Hi, I am using a 307 redirect to redirect traffic from an old site which has a google manual link penalty against it to a brand new site. My understanding is that 307 will not pass on link juice which is okay as I'm starting fresh with the new site, but I would hate to risk having the penalty from the old site being passed onto the new site. I am using a 307 in lieu of have a "Click Here to be directed to new site" page.. Thanks in advance.

Does it really matter to maintain 301 redirect after de-indexing of old URLs?
Today, I was reading latest blog post on SEOmoz blog about. Uncrawled 301s - A Quick Fix for When Relaunches Go Too Well This is very interesting study about 301 & How it useful to maintain traffic. I'm working on eCommerce website and I have done similar stuff on my website. I have big confusion to manage 301 redirect. My website generates new URLs due to following actions. Re-write dynamic URLs. Re-launch entire website on different eCommerce platform. [osCommerce to Magento Commerce] Re-name category. Trasfer one product from one category to another category. I'm managing my 301 redirect with old practice. Excel sheet data from Google webmaster tools and set specific new URLs for redirect. Hoooo... Now, I have 8.5K redirect in htaccess... And, I'm thinking it's too much. Can we remove old 301 redirect from htaccess or not? This is big question for me. Because, all pages are not hyperlink on external website. Google have just de-indexed old URLs and indexed new URLs. So, Is it require to maintain 301 redirect after Google process?

301 redirect on the root of the site
Due to some historic difficulties with our URL Rewriter, we are in the position of having the root of our site 301 redirected to another page. So the root of our site: http://www.propertylive.co.uk/ has a 301 redirect to: http://www.propertylive.co.uk/home.aspx We're aware that this isn't great and we're working to fix this completely, but what impact will this have on our SEO?
