How much juice do you lose in a 301 redirect?
-
Our site has a number of, shall we say, unoptimized URLs. I would like to change the URLs to be more relevant; if a page is about red widgets, the URL should be www.domain.com/red-widgets.html, right? I'm getting resistance on this, however, based on the belief that you lose something significant when you 301 an old URL to a new one.
Now, I know that if you have a long chain of redirects, the spiders will stop following at some point, and that is a huge problem. That wouldn't apply if there's only one step in the chain, however. I've also heard that you lose some link juice in a 301, but I'm unsure how serious that problem actually is. Is it small enough that we'd win out in the long run with better-optimized URLs?

Arafah, I respectfully disagree with loss of ranking and "link juice" (I hate that term - I prefer "page authority") being a misconception. Matt Cutts himself states that 301-redirects do not pass all the value of the original link. Here's a link to Eric Enge's article/interview with the quote directly from Matt Cutts: http://www.marketingpilgrim.com/2010/03/google-confirms-301-redirects-result-in-pagerank-loss.html

That's the best way to target that keyword, yes.

An optimized URL with 301 links is going to be better than a non-optimized URL with the same number of direct links. We don't know the exact loss in link value for a 301 redirect, and we don't know if it changes over time or in different circumstances, so any answer to this questions will be somewhat subjective. That said, I think most other SEOs would opt for Good URL with 301 links, and then they'd proceed to go build new links and change old ones where possible.
A personal guess is that the majority (>90%) of the link value is maintained in 301 redirects, however I couldn't say how it changes over time.
Now, I know that if you have a long chain of redirects, the spiders will stop following at some point, and that is a huge problem. That wouldn't apply if there's only one step in the chain, however.

Yes, you're better off with better-optimized URLs in most of the cases I've encountered.

If implemented properly, the URL should regain its "pagerank" for whats thats worth. I dont believe that the age of the url will make a difference but the backlinks definitely have at least some effect. You will want to do your best to have inbounds changed instead of redirecting where feasible.

Thanks! Would we be losing any value by discarding a URL that has been live for multiple years? I've heard that the age of a URL (not a domain) can help a page rank, but I'm not sure I believe that.

You do lose some juice on 301's so obviously the best course is to contact sites that house the link and ask them to change it to the new URL (once the new URL is live, and you would still 301 redirect). This isnt always easy to do particularly when there are 1000's of backlinks, so it really depends on how feasible an option that is, and how many backlinks you have (are there only 3? then having an optimized URL will probably be more beneficial than leaving the URL unoptimized, even if you cant have the links changed).
As to 'exactly' how much do you lose? I dont think anyone has a definitive answer. But I have worked with websites that 301 redirect almost every page when they migrate to a new platform and the SEO impact is not severe if done properly.
I still recommend mining your backlinks and having their targets chaged (at least for the more authoratative ones).

Solve Redirect Chains
I've gotten a few Redirect Issues that involve Redirect Chains, with the https:// version redirecting to the www. version and then redirecting to the right URL. Here is an example:
On-Page Optimization | | Billywig
Schermafbeelding 2021-12-07 om 11.04.32.png I've tried setting a direct redirect between the first and the last URL, but WordPress doesn't seem to allow that (it's overwritten). I've also tried checking the internal links to make sure that none of the links are the first one. They don't seem to be there. Does anyone have any tips on solving these Redirect Chains?0 -
My site auto redirects http to https. This is causing redirect chains. What can I do?
I noticed that Moz flags a lot of redirect chain issues on my site. I realized that this is mostly because the site automatically redirects http to https, and when I create a new URL (when a URL changes, for example) it is automatically flagged as a chain. Example: http://www.example-link Auto directs to: https://www.example-link Which is then redirected to: https://www.example-link-changed (when the address actually changes) I don't seem to have any control over changing where the initial http redirect goes. Any advice on fixing this problem?

How to 301 redirect, without access to .htaccess and to a new domain
There are few ways to do this and I would like to ask other Mozzers if they have found the best way. We have a site .co.uk and are moving it back to .com. However we do not have any access to the site folders for .co.uk. (We have to move it anyway as our provider is withdrawing their service). We have built our URL 301 redirect file and it is ready to go, but how to impliment it? We can repoint .co.uk to another site, and then redirect all traffic for each URL but this is quite messy, or just forget trying to 301 each page and just rediect the whole site.
On-Page Optimization | | BruceA
the .com has more authority already, but we ready do not want to frustrate visitors who are using a link to reach a product, only to find they hit our homepage and not the product. Your thoughts would be very welcome or other ideas Bruce0 -
301 Redirect to external site
Hi guys, We have a client who is getting their website redesigned through us. They are discontinuing couple of their services which will not get featured in the new site. They are fairly well ranked for these services and my client wishes to 301 redirect these pages to an external site owned by his friend so that they benefit out of the ranking. The question is: Will my client's website's general ranking get affected due to 301 redirecting to an external site? The external site is not spammy or red-flagged by Google (at the moment, at least). Thanks in advance!

Prevent link juice to flow on low-value pages
Hello there! Most of the websites have links to low-value pages in their main navigation (header or footer)... thus, available through every other pages. I especially think about "Conditions of Use" or "Privacy Notice" pages, which have no value for SEO. What I would like, is to prevent link juice to flow into those pages... but still keep the links for visitors. What is the best way to achieve this? Put a rel="nofollow" attribute on those links? Put a "robots" meta tag containing "noindex,nofollow" on those pages? Put a "Disallow" for those pages in a "robots.txt" file? Use efficient Javascript links? (that crawlers won't be able to follow)
