Do 404 Pages from Broken Links Still Pass Link Equity?
-
Hi everyone, I've searched the Q&A section, and also Google, for about the past hour and couldn't find a clear answer on this.
When inbound links point to a page that no longer exists, thus producing a 404 Error Page, is link equity/domain authority lost?
We are migrating a large eCommerce website and have hundreds of pages with little to no traffic that have legacy 301 redirects pointing to their URLs. I'm trying to decide how necessary it is to keep these redirects. I'm not concerned about the page authority of the pages with little traffic...I'm concerned about overall domain authority of the site since that certainly plays a role in how the site ranks overall in Google (especially pages with no links pointing to them...perfect example is Amazon...thousands of pages with no external links that rank #1 in Google for their product name).
Anyone have a clear answer? Thanks!

First off, thanks everyone for your replies
I'm well versed in best practices of 301 redirects, sitemaps, etc, etc. In other words, I fully know the optimal way to handle this. But, this is one of those situations where there are so many redirects involved (thousands) for a large site, that I want to make sure that what we are doing is fully worth the development time.
We are migrating a large website that was already migrated to a different CMS several years ago. There are thousands of legacy 301 redirects already in place for the current site, and many of those pages that are being REDIRECTED TO (from the old URL versions) receive very little/if any traffic. We need to decide if the work of redirecting them is worth it.
I'm not as worried about broken links for pages that don't get any traffic (although we ideally want 0 broken links). What I am most worried about, however, is losing domain authority and the whole site potentially ranking a little bit lower overall as a result.
Nakul's response (and Frederico's) are closest to what I am asking...but everyone is suggesting the same thing...that we will lose domain authority (example measurement: SEOmoz's OpenSiteExplorer domain authority score) if we don't keep those redirects in place (but of course, avoiding double redirects).
So, thanks again to everyone on this thread If anyone has a differing opinion, I'd love to hear it...but this is pretty much what I expected: everyone's best educated assessment is that you will lose domain authority when 301 redirects are lifted and broken links are the end result.

Great question Dan. @Jesse, you are on the right track. I think the question was misunderstood.
The question is, if seomoz.org links to Amazon.com/nakulgoyal and that page does not exist, is there link juice flow ? Think about it. It's like thinking about a citation. If seomoz.org mentions amazon.com/nakulgoyal, but does not actually have the hyperlink, is there citation flow.
So my question to the folks is, is there citation flow ? In my opinion, the answer is yes. There's some DA that will get passed along. Eventually, the site owner might identify the 404, "which they should" and setup a 301 redirect from Amazon.com/nakulgoyal to whatever pages makes most sense for the user, in which case there will be a proper link juice flow.
So to clarify what I said:
-
Scenario 1:
SiteA.com links to SiteB.com/urldoesnotexist - There is some (maybe close to negligible) domain authority flow. from siteA.com to siteB.com (Sort of like a link citation). There may not be a proper link juice flow, because the link is broken. -
Scenario 2:
SiteA.com links to SiteB.com/urldoesnotexist and this URL is 301 redirected SiteB.com/urlexists - In this case, there is both a authority flow and a link juice flow from SiteA.com to SiteB.com/urlexists
**That's my opinion. Think about it, the 301 redirect from /urldoesnotexist to /urlexists might get added 1 year from now and might be mistakenly removed at some point temporarily. There's going to be an affect in both cases. So in my opinion, the crux is, watch your 404's and redirect them when you and when it makes sense for the user. That way you have a good user experience and you can have the link juice flow where it should. **

Ideally you want to keep the number of 404 pages low because it tells the search engine that the page is a dead end, ask any SEO, it's best to keep the number of 404's as low as possible.
Link equity tells Google why to rank a page or give the root domain more authority. However, Google does not want users to end up on dead pages. So it will not help the site, rather hurt it. My recommendation is to create a sitemap and submit to Google WMT with the pages you want the spiders to index.
Limit the 404's as much as possible and try to 301 them if possible to a relevant page (from a user perspective).

I think, and correct me if I'm wrong Dan, you guys are misunderstanding the question.
He means that if you do actually create a 404 page for all your broken links to land on, will the juice pass from there to your domain (housing the 404 page) and on to whatever internal links you've built into said 404 page.
The answer, I think, is no. Reason for this is 404 is a status code returned before the 404 page is produced. Link juice can pass through either links (200) or redirects (301).
Again... I THINK.
Was this more what you were asking?
-
Equity is passed to a 404 page, which does not exist, therefore that equity is lost.
-
Thanks, Bryan. This doesn't really answer the exact question, though: is link equity still passed (and domain authority preserved) by broken links producing 404 Error Pages?
-
No they don't. Search engine spiders follow the link as a user, if the pages no longer exist and you cannot forward the user to a better page then create a good 404 page that will keep the users intrigued.

How can I identify links that point to a specific landing page with a specific anchor text on my own website?
I am trying to identify buttons and links that point to a specific landing page on our website that have a certain word in the anchor text and I would like to know the referring page URL too. Does anybody have an idea on how to do this? We have above a hundred landing pages and I would rather not go through them one by one 😄 Thanks for the help

Best way to link to 1000 city landing pages from index page in a way that google follows/crawls these links (without building country pages)?
Currently we have direct links to the top 100 country and city landing pages on our index page of the root domain.
Intermediate & Advanced SEO | | lcourse
I would like to add in the index page for each country a link "more cities" which then loads dynamically (without reloading the page and without redirecting to another page) a list with links to all cities in this country.
I do not want to dillute "link juice" to my top 100 country and city landing pages on the index page.
I would still like google to be able to crawl and follow these links to cities that I load dynamically later. In this particular case typical site hiearchy of country pages with links to all cities is not an option. Any recommendations on how best to implement?0 -
301 Externally Linked, But Non-Producing Pages, To Productive Pages Needing Links?
I'm working on a site that has some non-productive pages without much of an upside potential, but that are linked-to externally. The site also has some productive pages, light in external links, in a somewhat related topic. What do you think of 301ing the non-productive pages with links to the productive pages without links in order to give them more external link love? Would it make much of a difference? Thanks...

Internal links to preferential pages
Hi all, I have question about internal linking and canonical tags. I'm working on an ecommerce website which has migrated platform (shopify to magento) and the website design has been updated to a whole new look. Due to the switch to magento, the developers have managed to change the internal linking structure to product pages. The old set up was that category pages (on urls domain.com/collections/brand-name) for each brand would link to products via the following url format: domain.com/products/product-name . This product url was the preferential version that duplicate product pages generated by shopify would have their canonical tags pointing to. This set up was working fine. Now what's happened is that the category pages have been changed to link to products via dynamically generated urls based on the user journey. So products are now linked to via the following urls: domain.com/collection/brand-name/product-name . These new product pages have canonical tags pointing back to the original preferential urls (domain.com/products/product-name). But this means that the preferential URLs for products are now NOT linked to anywhere on the website apart from within canonical tags and within the website's sitemap. I'm correct in thinking that this definitely isn't a good thing, right? I've actually noticed Google starting to index the non-preferential versions of the product pages in addition to the preferential versions, so it looks like Google perhaps is ignoring the canonical tags as there are so many internal links pointing to non-preferential pages, and no on-site links to the actual preferential pages? I've recommended to the developers that they change this back to how it was, where the preferential product pages (domain.com/products/product-name) were linked to from collection pages. I just would like clarification from the Moz community that this is the right call to make? Since the migration to the new website & platform we've seen a decrease in search traffic, despite all redirects being set up. So I feel that technical issues like this can't be doing the website any favours at all. If anyone could help out and let me know if what I suggested is correct then that would be excellent. Thank you!

Effect of Removing Footer Links In all Pages Except Home Page
Dear MOZ Community: In an effort to improve the user interface of our business website (a New York CIty commercial real estate agency) my designer eliminated a standardized footer containing links to about 20 pages. The new design maintains this footer on the home page, but all other pages (about 600 eliminate the footer). The new design does a very good job eliminating non essential items. Most of the changes remove or reduce the size of unnecessary design elements. The footer removal is the only change really effect the link structure. The new design is not launched yet. Hoping to receive some good advice from the MOZ community before proceeding My concern is that removing these links could have an adverse or unpredictable effect on ranking. Last Summer we launched a completely redesigned version of the site and our ranking collapsed for 3 months. However unlike the previous upgrade this modifications does not URL names, tags, text or any major element. Only major change is the footer removal. Some of the footer pages provide good (not critical) info for visitors. Note the footer will still appear on the home page but will be removed on the interior pages. Are we risking any detrimental ranking effect by removing this footer? Can we compensate by adding text links to these pages if the links from the footer are removed? Seems irregular to have a home page footer but no footer on the other pages. Are we inviting any downgrade, penalty, adverse SEO effect by implementing this? I very much like the new design but do not want to risk a fall in rank and traffic. Thanks for your input!!!

How to Destroy Old 404 Pages
Hello Mozzers, So I just purchased a new domain and to my surprise it has a domain authority of 13 right out of the box (what luck!). I needed to investigate. To make a long story short the domain used to be home to a music blog that had hundreds of pages which of course are all missing now. I have about 400 pages on my hands that are resulting in a 404. How or what is the best method for eliminating these pages. Does deleting the Crawl Errors in Google Webmaster Tools do anything? Thanks

Category Pages up - Product Pages down... what would help?
Hi I mentioned yesterday how one of our sites was losing rank on product pages. What steps do you take to improve the SERPS of product pages, in this case home/category/product is the tree. There isn't really any internal linking, except one link from the category page to each product, would setting up a host of internal links perhaps "similar products" linking them together be a place to start? How can I improve my ranking of these more deeply internal pages? Not just internal links?
