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.

Link juice through URL parameters
Hi guys, hope you had a fantastic bank holiday weekend. Quick question re URL parameters, I understand that links which pass through an affiliate URL parameter aren't taken into consideration when passing link juice through one site to another. However, when a link contains a tracking URL parameter (let's say gclid=), does link juice get passed through? We have a number of external links pointing to our main site, however, they are linking directly to a unique tracking parameter. I'm just curious to know about this. Thanks, Brett

Splitting One Site Into Two Sites Best Practices Needed
Okay, working with a large site that, for business reasons beyond organic search, wants to split an existing site in two. So, the old domain name stays and a new one is born with some of the content from the old site, along with some new content of its own. The general idea, for more than just search reasons, is that it makes both the old site and new sites more purely about their respective subject matter. The existing content on the old site that is becoming part of the new site will be 301'd to the new site's domain. So, the old site will have a lot of 301s and links to the new site. No links coming back from the new site to the old site anticipated at this time. Would like any and all insights into any potential pitfalls and best practices for this to come off as well as it can under the circumstances. For instance, should all those links from the old site to the new site be nofollowed, kind of like a non-editorial link to an affiliate or advertiser? Is there weirdness for Google in 301ing to a new domain from some, but not all, content of the old site. Would you individually submit requests to remove from index for the hundreds and hundreds of old site pages moving to the new site or just figure that the 301 will eventually take care of that? Is there substantial organic search risk of any kind to the old site, beyond the obvious of just not having those pages to produce any more? Anything else? Any ideas about how long the new site can expect to wander the wilderness of no organic search traffic? The old site has a 45 domain authority. Thanks!

Links from non-indexed pages
Whilst looking for link opportunities, I have noticed that the website has a few profiles from suppliers or accredited organisations. However, a search form is required to access these pages and when I type cache:"webpage.com" the page is showing up as non-indexed. These are good websites, not spammy directory sites, but is it worth trying to get Google to index the pages? If so, what is the best method to use?

Best Practice for Inter-Linking to CCTLD brand domains
Team, I am wondering what people recommend as best SEO practice to inter-link to language specific brand domains e.g. : amazon.com
Intermediate & Advanced SEO | | tomypro
amazon.de
amazon.fr
amazon.it Currently I have 18 CCTLDs for one brand in different languages (no DC). I am linking from each content page to each other language domain, providing a link to the equivalent content in a separate language on a different CCTLD doamin. However, with Google's discouragement of site-wide links I am reviewing this practice. I am tending towards making the language redirects on each page javascript driven and to start linking only from my home page to the other pages with optimized link titles. Anyone having any thoughts/opinions on this topic they are open to sharing? /Thomas0 -
How to properly link to products from category pages?
Hi All, We have an e-commerce website and the category pages are built so that there is a product image and below it there is the title. Both the image and the title are in a href (each on its own). I encountered the following unfinished discussion here at MOZ:
Intermediate & Advanced SEO | | BeytzNet
http://www.seomoz.org/q/how-to-optimize-achor-text-links-on-ecommerce-category-page#post-93758 The discussion states that its improper. The question is - if it is wrong then why? (maybe because Google will give its weight to the image anchor instead of the text anchor since it is higher in the page). The other question is how to resolve the matter?
Should I add nofollow to the image href? Thanks0 -
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!

Best practice to redirects based on visitors' detected language
One of our websites has two languages, English and Italian. The English pages are available at the root level:
Intermediate & Advanced SEO | | Damiano
www.site.com/ English homepage www.site.com/page1
www.site.com/page2 The Italian pages are available under the /it/ level:
www.site.com/it Italian homepage www.site.com/it/pagina1
www.site.com/it/pagina2 When an Italian visitor first visits www.mysit.com we'd like to redirect it to www.site.com/it but we don't know if that would impact search engine spiders (eg GoogleBot) in any way... It would be better to do a Javascript redirect? Or an http 3xx redirect? If so, which of the 3xx redirect should we use? Thank you0
