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.

URL Structure & Best Practice when Facing 4+ Sub-levels
Hi. I've spent the last day fiddling with the setup of a new URL structure for a site, and I can't "pull the trigger" on it. Example: - domain.com/games/type-of-game/provider-name/name-of-game/ Specific example: - arcade.com/games/pinball/deckerballs/starshooter2k/ The example is a good description of the content that I have to organize. The aim is to a) define url structure, b) facilitate good ux, **c) **create a good starting point for content marketing and SEO, avoiding multiple / stuffing keywords in urls'. The problem? Not all providers have the same type of game. Meaning, that once I get past the /type-of-game/, I must write a new category / page / content for /provider-name/. No matter how I switch the different "sub-levels" around in the url, at one point, the provider-name doesn't fit as its in need of new content, multiple times. The solution? I can skip "provider-name". The caveat though is that I lose out on ranking for provider keywords as I don't have a cornerstone content page for them. Question: Using the URL structure as outlined above in WordPress, would you A) go with "Pages", or B) use "Posts"

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>

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.

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 -
Do I have to many internal links which is diluting link juice to less important pages
Hello Mozzers, I was looking at my homepage and subsequent category landing pages on my on my eCommerce site and wondered whether I have to many internal links which could in effect be diluting link juice to much of the pages I need it to flow. My homepage has 266 links of which 114 (43%) are duplicate links which seems a bit to much to me. One of my major competitors who is a national company has just launched a new site design and they are only showing popular categories on their home page although all categories are accessible from the menu navigation. They only have 123 links on their home page. I am wondering whether If I was to not show every category on my homepage as some of them we don't really have any sales from and only concerntrate on popular ones there like my competitors , then the link juice flowing downwards in the site would be concerntated as I would have less links for them to flow ?... Is that basically how it works ? Is there any negatives with regards to duplicate links on either home or category landing page. We are showing both the categories as visual boxes to select and they are also as selectable links on the left of a page ? Just wondered how duplicate links would be treated? Any thoughts greatly appreciated thanks Pete

Ecommerce Site homepage , Is it okay to have Links as H2 Tags as that is relevant to the page ?
Hi All, I have a Rental site and I am bit confused with how best do my H Tags on my homepage I know the H1 is the most important, Then H2 Tags and so on.. and that these tags should really be titles for content.

H3 Tags will my News and Guides etc , H4 Tags will the whats on the footer. I am attached a made up screenshot of what I propose for my homepage if someone could please give it a quick look , it would be very much appreciated. I have looked at what some competitors do a lot of them don't seem to have h2's etc but I know it's an important factor for rankings etc. Many thanks Pete dJSFQwI

Should my back links go to home page or internal pages
Right now we rank on page 2 for many KWs, so should i now focus my attention on getting links to my home page to build domain authority or continue to direct links to the internal pages for specific KWs? I am about to write some articles for several good ranking sites and want to know whether to link my company name (same as domain name) or KW to the home page or use individual KWs to the internal pages - I am only allowed one link per article to my site. Thanks Ash

Duplicate internal links on page, any benefit to nofollow
Link spam is naturally a hot topic amongst SEO's, particularly post Penguin. While digging around forums etc, I watched a video blog from Matt Cutts posted a while ago that suggests that Google only pays attention to the first instance of a link on the page As most websites will have multiple instances of a links (header, footer and body text), is it beneficial to nofollow the additional instances of the link? Also as the first instance of a link will in most cases be within the header nav, does that then make the content link text critical or can good on page optimisation be pulled from the title attribute? I would appreciate the experiences and thoughts Mozzers thoughts on this thanks in advance!
