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.

Fresh page versus old page climbing up the rankings.
Hello, I have noticed that if publishe a webpage that google has never seen it ranks right away and usually in a descend position to start with (not great but descend). Usually top 30 to 50 and then over the months it slowly climbs up the rankings. However, if my page has been existing for let's say 3 years and I make changes to it, it takes much longer to climb up the rankings Has someone noticed that too ? and why is that ?

Pagination on a product page with reviews spread out on multiple pages
Our current product pages markup only have the canonical URL on the first page (each page loads more user reviews). Since we don't want to increase load times, we don't currently have a canonical view all product page. Do we need to mark up each subsequent page with its own canonical URL? My understanding was that canonical and rel next prev tags are independent of each other. So that if we mark up the middle pages with a paginated URL, e.g: Product page #1http://www.example.co.uk/Product.aspx?p=2692"/>http://www.example.co.uk/Product.aspx?p=2692&pageid=2" />**Product page #2 **http://www.example.co.uk/Product.aspx?p=2692&pageid=2"/>http://www.example.co.uk/Product.aspx?p=2692" />http://www.example.co.uk/Product.aspx?p=2692&pageid=3" />Would mean that each canonical page would suggest to google another piece of unique content, which this obviously isn't. Is the PREV NEXT able to "override" the canonical and explain to Googlebot that its part of a series? Wouldn't the canonical then be redundant?Thanks

First Link on Page Still Only Link on Page?
Bruce Clay and others did some research and found that the first link on the page is the most important and what is accredited as the link. Any other links on the page mean nothing. Is this still true? And in that case, on an ecommerce site with category links in the top navigation (which is high on the code), is it not useful to link to categories in the content of the page? Because the category is already linked to on that page. Thank you, Tyler

Link Juice + multiple links pointing to the same page
Scenario
Intermediate & Advanced SEO | | Mark_Ch
The website has a menu consisting of 4 links Home | Shoes | About Us | Contact Us Additionally within the body content we write about various shoe types. We create a link with the anchor text "Shoes" pointing to www.mydomain.co.uk/shoes In this simple example, we have 2 instances of the same link pointing to the same url location.
We have 4 unique links.
In total we have 5 on page links. Question
How many links would Google count as part of the link juice model?
How would the link juice be weighted in terms of percentages?
If changing the anchor text in the body content to say "fashion shoes" have a different impact? Any other advise or best practice would be appreciated. Thanks Mark0 -
Outbound link to PDF vs outbound link to page
If you're trying to create a site which is an information hub, obviously linking out to authoritative sites is a good idea. However, does linking to a PDF have the same effect? e.g Linking to Google's SEO starter guide PDF, as opposed to linking to a google article on SEO. Thanks!

Does google detect all updated page with new links

Does having multiple links to the same page influence the Link juice this page is able to pass
Say you have a page and it has 4 outgoing links to the same internal page. In the original Pagerank algo if these links were links to an page outside your own domain, this would mean that the linkjuice this page is able to pass would be devided by 4. The thing is i'm not sure if this is also the case when the outgoing link, is linking to a page on your own domain. I would say that outgoing links (whatever the destination) will use some of your link juice, so it would be better to have 1 outgoing link instead of 4 to the same destination, the the destination will profit more form that link. What are you're thoughts?
