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.

Rel canonical tag from shopify page to wordpress site page
We have pages on our shopify site example - https://shop.example.com/collections/cast-aluminum-plaques/products/cast-aluminum-address-plaque That we want to put a rel canonical tag on to direct to our wordpress site page - https://www.example.com/aluminum-plaques/ We have links form the wordpress page to the shop page, and over time ahve found that google has ranked the shop pages over the wp pages, which we do not want. So we want to put rel canonical tags on the shop pages to say the wp page is the authority. I hope that makes sense, and I would appreciate your feeback and best solution. Thanks! Is that possible?

My last site crawl shows over 700 404 errors all with void(0 added to the ends of my posts/pages.
Hello, My last site crawl shows over 700 404 errors all with void(0 added to the ends of my posts/pages. I have contacted my theme company but not sure what could have done this. Any ideas? The original posts/pages are still correct and working it just looks like it did duplicates and added void(0 to the end of each post/page. Questions: There is no way to undo this correct? Do I have to do a redirect on each of these? Will this hurt my rankings and domain authority? Any suggestions would be appreciated. Thanks, Wade

404 Errors flaring on nonexistent or unpublished pages – should we be concerned for SEO?
Hello! We keep getting "critical crawler" notifications on Moz because of firing 404 codes. We've checked each page and know that we are not linking to them anywhere on our site, they are not published and they are not indexed on Google. It's only happened since we migrated our blog to Hubspot so we think it has something to do with the test pages their developers had set up and that they are just lingering in our code somewhere. However, we are still concerned having these codes fire implies negative consequences for our SEO. Is this the case? Should we be concerned about these 404 codes despite the pages from those URLs not actually existing? Thank you!

Are In-Page Tabs still detrimental to SEO?
Hi Mozers, Are in-page tabs still detrimental for SEO? In-page tabs: allow you to alternate between views within the same context, not to navigate to different areas. As in one long HTML page that just looks like it's divided into different pages via tabs that you can click between. Each tab has it's own URL, which I guess is for analytics tracking purposes? https://XXX https://XXX?qt-staff_profile_tabs=1 https://XXX?qt-staff_profile_tabs=2 https://XXX?qt-staff_profile_tabs=3

How Many Links to Disavow at Once When Link Profile is Very Spammy?
We are using link detox (Link Research Tools) to evaluate our domain for bad links. We ran a Domain-wide Link Detox Risk report. The reports showed a "High Domain DETOX RISK" with the following results: -42% (292) of backlinks with a high or above average detox risk
Intermediate & Advanced SEO | | Kingalan1
-8% (52) of backlinks with an average of below above average detox risk
-12% (81) of backlinks with a low or very low detox risk
-38% (264) of backlinks were reported as disavowed. This look like a pretty bad link profile. Additionally, more than 500 of the 689 backlinks are "404 Not Found", "403 Forbidden", "410 Gone", "503 Service Unavailable". Is it safe to disavow these? Could Google be penalizing us for them> I would like to disavow the bad links, however my concern is that there are so few good links that removing bad links will kill link juice and really damage our ranking and traffic. The site still ranks for terms that are not very competitive. We receive about 230 organic visits a week. Assuming we need to disavow about 292 links, would it be safer to disavow 25 per month while we are building new links so we do not radically shift the link profile all at once? Also, many of the bad links are 404 errors or page not found errors. Would it be OK to run a disavow of these all at once? Any risk to that? Would we be better just to build links and leave the bad links ups? Alternatively, would disavowing the bad links potentially help our traffic? It just seems risky because the overwhelming majority of links are bad.0 -
Substantial difference between Number of Indexed Pages and Sitemap Pages
Hey there, I am doing a website audit at the moment. I've notices substantial differences in the number of pages indexed (search console), the number of pages in the sitemap and the number I am getting when I crawl the page with screamingfrog (see below). Would those discrepancies concern you? The website and its rankings seems fine otherwise. Total indexed: 2,360 (Search Consule)

Should the sitemap include just menu pages or all pages site wide?
I have a Drupal site that utilizes Solr, with 10 menu pages and about 4,000 pages of content. Redoing a few things and we'll need to revamp the sitemap. Typically I'd jam all pages into a single sitemap and that's it, but post-Panda, should I do anything different?

Are duplicate links on same page alright?
If I have a homepage with category links, is it alright for those category links to appear in the footer as well, or should you never have duplicate links on one page? Can you please give a reason why as well? Thanks!
