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>

Yes, but article got 1y so it can be not so accurate now.

Hi Krzysztof,
Not too much information out there regarding how much link equity is passed through a javascript link, however, this study published by Branded3.com shows their evidence that 'pagerank' is passed through JavaScript redirects. Again, I don't know how much equity is being lost due to the JavaScript redirect (if any) but I imagine links would be treated in a similar manner.

I think the same but need some more "proofs" like a/b tests or something.

Hi Krzysztof,
It's best practice for internal links to have href attributes. My understanding is although Google will be able to find internal links dependant on JavaScript, they're not treated the same, and that the passing of page rank will be negatively impacted.

Footer no follow links
Just interested to know when putting links at the foot of the site some people use no-follow tags. I'm thinking about internal pages and social networks. Is this still necessary or is it an old-fashioned idea?

Switching from Http to Https, but what about images and image link juice?
Hi Ya'll. I'm transitioning our http version website to https. Important question: Do images have to have 301 redirects? If so, how and where? Please send me a link or explain best practices. Best, Shawn

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

Does google credit links from iFrames or created by Javascript, if so, is one more powerful than the other?
Consider this example, because I want to be clear about what I mean. You have two websites. Lets all them www.a.com and www.b.com. On www.a.com/some/page, there is an iframe something like this:
Intermediate & Advanced SEO | | A Former User
<iframe src="www.b.com/some/special/path"></iframe>
Then content of this iframe is a bunch of pictures, text and numbers, as well as a group of links, linking each picture to www.b.com for example the links might be:
www.b.com/content/1
www.b.com/content/2
www.b.com/content/3 Questions: When google crawls **www.a.com/some/page, **does it pass link juice to www.b.com/content/*? Does google instead consider these to be internal links within b.com itself. because links to www.b.com/content/ ** are actually from b.com itself, since the domain of the iframe is actually: www.b.com/some/special/path 3) Is there any amount of link juice passed from www.a.com/some/page to* www.b.com/some/special/path **because this is the src= element of an iframe that a.com is hosting? Consider an alternative setup. Where instead of using an iframe the contents of the above described iFrame is actually added the the page dynamically using javascript, and a call to an API endpoint at b.com. Resulting in these links being added directly to the body of a.com without being wrapped in an iframe element. Questions:
4) Do these links that were created after page load still get crawled and credited by google? (i have heard in the past that google was going to start crawling javascript, i just don't know if this is known for a fact yet).
5) Do links created on the client side hold the same weight as a link that was served directly via the backend html generation? If both the links within the iframe and the links within the javascript embed method pass link juice. Is one preferred over the other? is one known to be more effective than the other? Thanks!0 -
Do 404s really 'lose' link juice?
It doesn't make sense to me that a 404 causes a loss in link juice, although that is what I've read. What if you have a page that is legitimate -- think of a merchant oriented page where you sell an item for a given merchant --, and then the merchant closes his doors. It makes little sense 5 years later to still have their merchant page so why would removing them from your site in any way hurt your site? I could redirect forever but that makes little sense. What makes sense to me is keeping the page for a while with an explanation and options for 'similar' products, and then eventually putting in a 404. I would think the eventual dropping out of the index actually REDUCES the overall link juice (ie less pages), so there is no harm in using a 404 in this way. It also is a way to avoid the site just getting bigger and bigger and having more and more 'bad' user experiences over time. Am I looking at it wrong? ps I've included this in 'link building' because it is related in a sense -- link 'paring'.

Wikipedia links - any value?
Hello everyone. We recently posted some of our research to Wikipedia as references in the "External Links" section. Our research is rigorous and has been referenced by a number of universities and libraries (an example: https://www.harborcompliance.com/information/company-suffixes.php). Anyway, I'm wondering if these Wikipedia links have any value beyond of course adding to the Wiki page's information. Thanks!

Cross linking between categories
Is it useful for SEO to cross link between TOP level categories, let's say I have a Home page and then 2 sub categories, one about green widgets one about red widgets
Intermediate & Advanced SEO | | seoanalytics
Should i create a link from the green widget to the red widget or should I leave those are separate silos ? I know that within a silo i need to cross link ( from green widget 1 to green widget 2 etc... ) but how about about from the main category to the other main category ?0 -
Noindex,follow is a waste of link juice?
On my wordpress shopping cart plugin, I have three pages /account, /checkout and /terms on which I have added “noindex,follow” attribute. But I think I may be wasting link juice on these pages as they are not to be indexed anyway, so is there any point giving them any link juice? I can add “noindex,nofollow” on to the page itself. However, the actual text/anchor link to these pages on the site header will remain “follow” as I have no means of amending that right now. So this presents the following two scenarios – No juice flows from homepage to these 3 pages (GOOD) – This would be perfect then, as the pages themselves have nofollow attribute. Juice flows from homepage to these pages (BAD) - This may mean that the juice flows from homepage anchor text links to these 3 pages BUT then STOPS there as they have “nofollow” attribute on that page. This will be a bigger problem and if this is the case and I cant stop the juice from flowing in, then ill rather let it flow out to other pages. Hope you understand my question, any input is very much appreciated. Thanks
