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.

URL structure - Page Path vs No Page Path
We are currently re building our URL structure for eccomerce websites. We have seen a lot of site removing the page path on product pages e.g. https://www.theiconic.co.nz/liberty-beach-blossom-shirt-680193.html versus what would normally be https://www.theiconic.co.nz/womens-clothing-tops/liberty-beach-blossom-shirt-680193.html Should we be removing the site page path for a product page to keep the url shorter or should we keep it? I can see that we would loose the hierarchy juice to a product page but not sure what is the right thing to do.

Category Page as Shopping Aggregator Page
Hi, I have been reviewing the info from Google on structured data for products and started to ponder.
Intermediate & Advanced SEO | | Alexcox6
https://developers.google.com/search/docs/data-types/products Here is the scenario.
You have a Category Page and it lists 8 products, each products shows an image, price and review rating. As the individual products pages are already marked up they display Rich Snippets in the serps.
I wonder how do we get the rich snippets for the category page. Now Google suggest a markup for shopping aggregator pages that lists a single product, along with information about different sellers offering that product but nothing for categories. My ponder is this, Can we use the shopping aggregator markup for category pages to achieve the coveted rich results (from and to price, average reviews)? Keen to hear from anyone who has had any thoughts on the matter or had already tried this.0 -
Passing link juice via javascript?
Hello Client got website with javascript generated content. All links there (from mainpage to some deeper page) are js generated. In code there're only javascripts and other basic typical code but no text links (<a href...="" ).<="" p=""></a> <a href...="" ).<="" p="">The question is: are those js links got the same "seo power" as typical html href links?.For example majestic.com can't scan website properly and can't show seo metrics for pages. I know google crawls them (links and pages) but are they as good as typical links?</a> <a href...="" ).<="" p="">Regards,</a>

Can noindexed pages accrue page authority?
My company's site has a large set of pages (tens of thousands) that have very thin or no content. They typically target a single low-competition keyword (and typically rank very well), but the pages have a very high bounce rate and are definitely hurting our domain's overall rankings via Panda (quality ranking). I'm planning on recommending we noindexed these pages temporarily, and reindex each page as resources are able to fill in content. My question is whether an individual page will be able to accrue any page authority for that target term while noindexed. We DO want to rank for all those terms, just not until we have the content to back it up. However, we're in a pretty competitive space up against domains that have been around a lot longer and have higher domain authorities. Like I said, these pages rank well right now, even with thin content. The worry is if we noindex them while we slowly build out content, will our competitors get the edge on those terms (with their subpar but continually available content)? Do you think Google will give us any credit for having had the page all along, just not always indexed?

Redirected Old Pages Still Indexed
Hello, we migrated a domain onto a new Wordpress site over a year ago. We redirected (with plugin: simple 301 redirects) all the old urls (.asp) to the corresponding new wordpress urls (non-.asp). The old pages are still indexed by Google, even though when you click on them you are redirected to the new page. Can someone tell me reasons they would still be indexed? Do you think it is hurting my rankings?

Does 302 pass link juice?
Hi! We have our content under two subdomains, one for the English language and one for Spanish. Depending on the language of the browser, there's a 302 redirecting to one of this subdomains. However, our main domain (which has no content) is receiving a lot of links - people rather link to mydomain.com than to en.mydomain.com. Does the 302 passing any link juice? If so, to which subdomain? Thank you!
