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).

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.

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 -
How long should I leave an existing web page up after a 301 redirect?
I've been reading through a few of blog posts here on moz and can't seem to find the answer to these two questions: How long should I leave an existing page up after a 301 redirect? The page old page is no longer needed but has pretty high page authority. If I take the old page down—the one that I'm redirecting from—immediately after I set up the 301 redirect, will link juice still be passed to the new page? My second question is, right now, on my index.html page I have both a 301 redirect and a rel canonical tag in the head. They were both put in place to redirect and pass link equity respectively. I did this a couple years back after someone recommended that I do both just to be safe, but from what I've gathered reading the articles here on moz is that your supposed to pick one or the other depending on whether or not it's permanent. Should I remove the rel conanical tag or would it be better to just leave it be?

How Much Does Punctuation of a Word Effect SEO?
I have a page on a site that is targeted for "mens hair cut" and I have received a F for the grade. The content on the page uses "men's" throughout the content. (proper punctuation) When I re-graded the page with "men's hair cut" the page received a B grade. My question is, does mens v.s men's make a different for on-page SEO? Should my targeted keywords include "men's" rather than "mens"?

What is the best way to execute a geo redirect?
Based on what I've read, it seems like everyone agrees an IP-based, server side redirect is fine for SEO if you have content that is "geo" in nature. What I don't understand is how to actually do this. It seems like after a bit of research there are 3 options: You can do a 301 which it seems like most sites do, but that basically means if google crawls you in different US areas (which it may or may not) it essentially thinks you have multiple homepages. Does google only crawl from SF-based IPs? 302 passes no juice, so probably don't want to do that. Yelp does a 303 redirect, which it seems like nobody else does, but Yelp is obviously very SEO-savvy. Is this perhaps a better way that solves for the above issues? Thoughts on what is best approach here?

ALT tagging images with keyword. What is too much?
I was wondering about the best practices of ALT tags in images. Say if you have an eCommerce site and you're on a product page. This product page has 5 images of the same product (different images), should you give every image an Alt tag with the keyword for that page? Or, is that keyword stuffing, and it would actually be best practice be to provide alt tags on just one image?

301 Redirect to product page or category?
We manage an ecommerce website that sells health products. A few products have now been discontinued. I’m just wondering what would be the best practice in this case. Should we 301 redirect to a similar product or to a similar category page? ANY HELP IS GREATLY APPRECIATED!

Mega Menus? A good or bad idea for link juice.
Hi Just wondering what people think of using mega menus for navigation? We have used them on our new site http://nicontrols.com/uk/ When I run the site through the excellent SEOMoz campaign tools I see that we have too many on page links. I now believe the menu is good for customers but maybe not for link juice. Anyone got an ideas? Do I remove the mega menu or just reduce the number of links? Many thanks David

Does having a "+" in a URL hurt SEO? Would much value be gained changing it to a hyphen?
There's a site that contains "+" signs in the URL in order to call different information for the content on the page. Would it be better to change those to hyphens (-), or not that much value will be gained, so leave them as is? Thanks!
