Do 404 pages pass link juice? And best practices...
-
Last year Google said bad links to 404 pages wouldn't hurt your site. Could that still be the case in light of recent Google updates to try and combat spammy links and negative SEO?
Can links to 404 pages benefit a website and pass link juice? I'd assume at the very least that any link juice will pass through links FROM the 404 page?
Many websites have great 404 pages that get linked to: http://www.opensiteexplorer.org/links?site=http%3A%2F%2Fretardzone.com%2F404 - that was the first of four I checked from the "60 Really Cool...404 Pages" that actually returned the 404 HTTP Status! So apologies if you find the word 'retard' offensive. According to Open Site Explorer it has a decent Page Authority and number of backlinks - but it doesn't show in Google's SERPs.
I'd never do it, but if you have a particularly well-linked to 404 page, is there an argument for giving it 200 OK Status?
Finally, what are the best practices regarding 404s and address bar links?
For example, if
www.examplesite.com/3rwdfs returns a 404 error, should I make that redirect to
www.examplesite.com/404 or leave it as is?Redirecting to www.examplesite.com/404 might not be user-friendly as people won't be able to correct the URL in the address bar. But if I have a great 404 page that people link to, I don't want links going to loads of random pages do I? Is either way considered best practice?
If I did a 301 redirect I guess it would send the wrong signal to the crawlers? Should I use a 302 redirect, or even a 304 Not Modified redirect?

This is a fascinating question.
Regarding your question about 404 pages getting a 200 status. So obviously, Google doesn't index 404 pages, and de-indexed pages do not pass on link juice. However, like you say, some people and sites link to 404 pages and so, were these ever to go live, you'd imagine it would have some sort of strength/authority.
But how could you practically accomplish this? If you make the 404 page a 200 page, you've now got no 404 page for your website, which could be very bad indeed. So, you'd probably want to substitute that page with a new, fresh 404 page. But if that sits as the 404 page and gets marked as a 404, wouldn't the links become void again?
If you then moved the old 404 to a new page, it loses the links once pointing to it.
The hongkiat webpage is a really clever idea as it takes all those pages and makes a shareable hub, which of course then gets all the links and strength.

Should I apply Canonical Links from my Landing Pages to Core Website Pages?
I am working on an SEO project for the website: https://wave.com.au/ There are some core website pages, which we want to target for organic traffic, like this one: https://wave.com.au/doctors/medical-specialties/anaesthetist-jobs/ Then we have basically have another version that is set up as a landing page and used for CPC campaigns. https://wave.com.au/anaesthetists/ Essentially, my question is should I apply canonical links from the landing page versions to the core website pages (especially if I know they are only utilising them for CPC campaigns) so as to push link equity/juice across? Here is the GA data from January 1 - April 30, 2019 (Behavior > Site Content > All Pages😞

What are best page titles for sub-domain pages?
Hi Moz communtity, Let's say a website has multiple sub-domains with hundreds and thousands of pages. Generally we will be mentioning "primary keyword & "brand name" on every page of website. Can we do same on all pages of sub-domains to increase the authority of website for this primary keyword in Google? Or it gonna end up as negative impact if Google consider as duplicate content being mentioned same keyword and brand name on every page even on website and all pages of sub domains? Thanks

What is best practice for "Sorting" URLs to prevent indexing and for best link juice ?
We are now introducing 5 links in all our category pages for different sorting options of category listings.
Intermediate & Advanced SEO | | lcourse
The site has about 100.000 pages and with this change the number of URLs may go up to over 350.000 pages.
Until now google is indexing well our site but I would like to prevent the "sorting URLS" leading to less complete crawling of our core pages, especially since we are planning further huge expansion of pages soon. Apart from blocking the paramter in the search console (which did not really work well for me in the past to prevent indexing) what do you suggest to minimize indexing of these URLs also taking into consideration link juice optimization? On a technical level the sorting is implemented in a way that the whole page is reloaded, for which may be better options as well.0 -
Will I lose Link Juice when implementing a Reverse Proxy?
My company is looking at consolidating 5 websites that it has running on magento, wordpress, drupal and a few other platforms on to the same domain. Currently they're all on subdomains but we'd like to consolidate the subdomains to folders for UX and SEO potential. Currently they look like this: shop.example.com blog.example.com uk.example.com us.example.com After the reverse proxy they'll look like this: example.com/uk/ example.com/us/ example.com/us/shop example.com/us/blog I'm curious to know how much link juice will be lost in this switch. I've read a lot about site migration (especially the Moz example). A lot of these guides/case studies just mention using a bunch of 301's but it seems they'd probably be using reveres proxies as well. My questions are: Is a reverse proxy equal to or worse/better than a 301? Should I combine reverse proxy with a 301 or rel canonical tag? When implementing a reverse proxy will I lose link juice = ranking? Thanks so much! Jacob

Mega Menu Navigation Best Practice
First off, I'm a landscape/nature/travel photographer. I mainly sell prints of my work. I'm in the process of redesigning my website, and I'm trying to decide whether to keep the navigation extremely simple or leave the drop-down menu for galleries. Currently, my navigation is something like this: Galleries

> Gallery for State or Country (example: California)
> Sub-region in State or Country (example: San Francisco)
Blog
Prints
About
Contact Selling prints is the top priority of the website, as that's what runs the business. I have lots of blog content, and I'm starting to build some good travel advice, etc. but in reality, the galleries, which then filter down to individual pages for each photo with a cart system, are the most important. What I'm struggling to decide is whether to leave the sort of "mega menu" for the galleries, or to do away with them, and have the user go to the overall galleries page to navigate further into the site. Leaving the mega menu intact, the galleries page becomes a lot less important, and takes out a step to get to the shopping cart. However, I'm wondering if the amount of galleries in the drop down menu is giving TOO many choices up front as well. I also wonder how changing this will affect search. Any thoughts on which is better or is it really just a matter of preference?0 -
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?

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!

There's a website I'm working with that has a .php extension. All the pages do. What's the best practice to remove the .php extension across all pages?
Client wishes to drop the .php extension on all their pages (they've got around 2k pages). I assured them that wasn't necessary. However, in the event that I do end up doing this what's the best practices way (and easiest way) to do this? This is also a WordPress site. Thanks.
