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.

Best practice for deindexing large quantities of pages
We are trying to deindex a large quantity of pages on our site and want to know what the best practice for doing that is. For reference, the reason we are looking for methods that could help us speed it up is we have about 500,000 URLs that we want deindexed because of mis-formatted HTML code and google indexed them much faster than it is taking to unindex them unfortunately. We don't want to risk clogging up our limited crawl log/budget by submitting a sitemap of URLs that have "noindex" on them as a hack for deindexing. Although theoretically that should work, we are looking for white hat methods that are faster than "being patient and waiting it out", since that would likely take months if not years with Google's current crawl rate of our site.

Faceted Navigation URLs Best Practices
Hi, We are developing new Products Pages with faceted filters. You can see it here: https://www.viatrading.com/wholesale-products/ We have a feature allowing to Order By and Group By, which alters the order of all products. There will also be the option to view Products as a table, which will contain same products but with different design and maybe slightly different content of each product. All this will happen without changing the URL, https://www.viatrading.com/all/ Is this the best practice? Thanks,

Best-practice URL structures with multiple filter combinations
Hello, We're putting together a large piece of content that will have some interactive filtering elements. There are two types of filters, topics and object types. The architecture under the hood constrains us so that everything needs to be in URL parameters. If someone selects a single filter, this can look pretty clean: www.domain.com/project?topic=firstTopic
Intermediate & Advanced SEO | | digitalcrc
or
www.domain.com/project?object=typeOne The problems arise when people select multiple topics, potentially across two different filter types: www.domain.com/project?topic=firstTopic-secondTopic-thirdTopic&object=typeOne-typeTwo I've raised concerns around the structure in general, but it seems to be too late at this point so now I'm scratching my head thinking of how best to get these indexed. I have two main concerns: A ton of near-duplicate content and hundreds of URLs being created and indexed with various filter combinations added Over-reacting to the first point above and over-canonicalizing/no-indexing combination pages to the detriment of the content as a whole Would the best approach be to index each single topic filter individually, and canonicalize any combinations to the 'view all' page? I don't have much experience with e-commerce SEO (which this problem seems to have the most in common with) so any advice is greatly appreciated. Thanks!0 -
Website Redesign, 301 Redirects, and Link Juice
I want to change my client’s ecommerce site to Shopify. The only problem is that Shopify doesn’t let you customize domains. I plan to: keep each page’s content exactly the same keep the same domain name 301 redirect all of the pages to their new url The ONLY thing that will change is each page’s url. Again, each page will have the exact same content. The only source of traffic to this site is via Google organic search and sales depend on the traffic. There are about 10 pages that have excellent link juice, 20 pages that have medium link juice, and the rest is small link juice. Many of our links that have significant link juice are on message boards written by people that like our product. I plan to change these urls and 301 redirect them to their new urls. I’ve read tons of pages online about this topic. Some people that say it won’t effect link juice at all, some say it will might effect link juice temporarily, and others are uncertain. Most answers tend to be “You should be good. You might lose some traffic temporarily. You might want to switch some of your urls to the new structure to see how it affects it first.” Here’s my question: 1) Has anyone ever done changed a url structure for an existing website with link juice? What were your results and do you have a definitive answer on the topic? 2) How much link juice (if any) will be lost if I keep all of the exact content the same but only change each page’s url? 3) If link juice is temporarily lost and then regained, how long will it be temporarily lost? 1 week? 1 month? 6 months? Thanks.

Image URLs - best practice
Hi - I'm assuming image URL best practice follows same principles as non image URLs (not too many files and so on) - I notice alot of web devs putting photos in subdomains, so wonder if I'm missing something (I usually avoid subdomains like the plague)!

Do internal links from non-indexed pages matter?
Hi everybody! Here's my question. After a site migration, a client has seen a big drop in rankings. We're trying to narrow down the issue. It seems that they have lost around 15,000 links following the switch, but these came from pages that were blocked in the robots.txt file. I was wondering if there was any research that has been done on the impact of internal links from no-indexed pages. Would be great to hear your thoughts! Sam

Whats the best way to remove search indexed pages on magento?
A new client ( aqmp.com.br/ )call me yestarday and she told me since they moved on magento they droped down more than US$ 20.000 in sales revenue ( monthly)... I´ve just checked the webmaster tool and I´ve just discovered the number of crawled pages went from 3.260 to 75.000 since magento started... magento is creating lots of pages with queries like search and filters. Example: http://aqmp.com.br/acessorios/lencos.html http://aqmp.com.br/acessorios/lencos.html?mode=grid http://aqmp.com.br/acessorios/lencos.html?dir=desc&order=name Add a instruction on robots.txt is the best way to remove unnecessary pages of the search engine?
