Do 404s really 'lose' link juice?
-
It doesn't make sense to me that a 404 causes a loss in link juice, although that is what I've read. What if you have a page that is legitimate -- think of a merchant oriented page where you sell an item for a given merchant --, and then the merchant closes his doors. It makes little sense 5 years later to still have their merchant page so why would removing them from your site in any way hurt your site? I could redirect forever but that makes little sense. What makes sense to me is keeping the page for a while with an explanation and options for 'similar' products, and then eventually putting in a 404. I would think the eventual dropping out of the index actually REDUCES the overall link juice (ie less pages), so there is no harm in using a 404 in this way. It also is a way to avoid the site just getting bigger and bigger and having more and more 'bad' user experiences over time.
Am I looking at it wrong?
ps I've included this in 'link building' because it is related in a sense -- link 'paring'.

Thanks Amelia!

I may be being pedantic here but I think the correct status code should be 410 not 404 if the page has gone for good and you don't have a relevant place to redirect traffic to, as per the scenario described.
I believe if Google finds a 410 page, it'll be removed from the index but because 404 is 'file not found' the page may stay in the index, potentially giving bad user experience as outlined by Matt Williamson.
However, I would always redirect if you can - even if you just send traffic to the homepage, it's got to be a better user experience than sending them to a 404 page. I think anyway!

You mention a concern over too many redirects - I think this page may help eliminate your fears: http://www.stateofdigital.com/matt-cutts-there-is-no-limit-to-direct-301-redirects-there-is-on-chains/
Thanks,

Matt, thanks.. Good points for sure. My concern is that since something like 50% of new businesses close doors within 5 years, so the list of redirected urls will just keep getting bigger over time..Is that a concern? I guess over time less people will link to the defunct businesses, but I will still have to track them..maybe at some point when the number of links to them is small it would make sense to then 404 them? Of course, I'd still need to track which ones to 404, so i'm now wondering when 404 ever makes sense on prior legitimate pages..
Just to be clear -- redirecting does remove the old link from the index, right?

404's can loose link juice and cause the most issues when a page that had lots of link pointing to it passing authority becomes a 404 page. As this page no longer exists the authority that was being passed to it from the links that were pointing at it will be lost when Google eventually de-indexes the page. You also must remember that this page is likely to be in Google Index and if people click on it and it is not found they are more likely to bounce from your site. You will also loose what terms this page was ranking for when it is eventually de-indexed as well. Redirecting this page to its new location or a similar/relevant page will help keep most of this authority that has been earnt helping with your ranking and keeping human visitors happy.
You also need to think of this from a crawl point of view - lots of 404s doesn't make your site very friendly as Googlebot is wasting time trying to crawl pages that don't exist. Ultimately making sure you don't have 404 pages and keep on top of redirecting these is important particularly if the page had authority. A great big hint to the importance is the fact that Google reports these crawl issues in Google Webmaster Tools in order for you to be able to monitor and fix them.
On a side note I have seen cases where sites have had a lot of 404s due to a significant change of URL structure and they haven't done any redirects - they have lost the majority of their organic rankings and traffic!

Change Google's version of Canonical link
Hi My website has millions of URLs and some of the URLs have duplicate versions. We did not set canonical all these years. Now we wanted to implement it and fix all the technical SEO issues. I wanted to consolidate and redirect all the variations of a URL to the highest pageview version and use that as the canonical because all of these variations have the same content. While doing this, I found in Google search console that Google has already selected another variation of URL as canonical and not the highest pageview version. My questions: I have millions of URLs for which I have to do 301 and set canonical. How can I find all the canonical URLs that Google has autoselected? Search Console has a daily quota of 100 or something. Is it possible to override Google's version of Canonical? Meaning, if I set a variation as Canonical and it is different than what Google has already selected, will it change overtime in Search Console? Should I just do a 301 to highest pageview variation of the URL and not set canonicals at all? This way the canonical that Google auto selected might get redirected to the highest pageview variation of the URL. Any advice or help would be greatly appreciated.

Duplicate Content through 'Gclid'
Hello, We've had the known problem of duplicate content through the gclid parameter caused by Google Adwords. As per Google's recommendation - we added the canonical tag to every page on our site so when the bot came to each page they would go 'Ah-ha, this is the original page'. We also added the paramter to the URL parameters in Google Wemaster Tools. However, now it seems as though a canonical is automatically been given to these newly created gclid pages; below https://www.google.com.au/search?espv=2&q=site%3Awww.mypetwarehouse.com.au+inurl%3Agclid&oq=site%3A&gs_l=serp.3.0.35i39l2j0i67l4j0i10j0i67j0j0i131.58677.61871.0.63823.11.8.3.0.0.0.208.930.0j3j2.5.0....0...1c.1.64.serp..8.3.419.nUJod6dYZmI Therefore these new pages are now being indexed, causing duplicate content. Does anyone have any idea about what to do in this situation? Thanks, Stephen.

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.

Do links to PDF's on my site pass "link juice"?
Hi, I have recently started a project on one of my sites, working with a branch of the U.S. government, where I will be hosting and publishing some of their PDF documents for free for people to use. The great SEO side of this is that they link to my site. The thing is, they are linking directly to the PDF files themselves, not the page with the link to the PDF files. So my question is, does that give me any SEO benefit? While the PDF is hosted on my site, there are no links in it that would allow a spider to start from the PDF and crawl the rest of my site. So do I get any benefit from these great links? If not, does anybody have any suggestions on how I could get credit for them. Keep in mind that editing the PDF's are not allowed by the government. Thanks.

Redirecting one site to another for link juice
I have two sites with same theme - buying cars. I am going remove one of the sites from being crawled permenantly (ie junkthecars.com) and point domian via 301, to another similar theme site (sellthecars.com). The purpose is to simply pass the SEO link juice from one site to the other as we retire junkthecars.com.... Is a forwarding of the domain OK and the best way for the search engines to increase the rank of sellthecars.com (we hate to wast the link work done on Junkthecars.com)? What dangers should I look for that could hurt sellthecars.com if we do the redirect at a simple TLD?

Site wide footer links vs. single link for websites we design
I’ve been running a web design business for the past 5 years, 90% or more of the websites we build have a “web design by” link in the footer which links back to us using just our brand name or the full “web design by brand name” anchor text. I’m fully aware that site-wide footer links arent doing me much good in terms of SEO, but what Im curious to know is could they be hurting me? More specifically I’m wondering if I should do anything about the existing links or change my ways for all new projects, currently we’re still rolling them out with the site-wide footer links. I know that all other things being equal (1 link from 10 domains > 10 links from 1 domain) but is (1 link from 10 domains > 100 links from 10 domains)? I’ve got a lot of branded anchor text, which balances out my exact match and partial match keyword anchors from other link building nicely. Another thing to consider is that we host many of our clients which means there are quite a few on the same server with a shared IP. Should I? 1.) Go back into as many of the sites as I can and remove the link from all pages except the home page or a decent PA sub page- keeping a single link from the domain. 2.) Leave all the old stuff alone but start using the single link method on new sites. 3.) Scratch the site credit and just insert an exact-match anchor link in the body of the home page and hide with with CSS like my top competitor seems to be doing quite successfully. (kidding of course.... but my competitor really is doing this.)

Is there any negative SEO effect of having comma's in URL's?
Hello, I have a client who has a large ecommerce website. Some category names have been created with comma's in - which has meant that their software has automatically generated URL's with comma's in for every page that comes beneath the category in the site hierarchy. eg. 1 : http://shop.deliaonline.com/store/music,-dvd-and-games/dvds-and-blu_rays/ eg. 2 : http://shop.deliaonline.com/store/music,-dvd-and-games/dvds-and-blu_rays/action-and-adventure/ etc... I know that URL's with comma's in look a bit ugly! But is there 'any' SEO reason why URL's with comma's in are any less effective? Kind Regs, RB
