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:
<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/3Questions:
- 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!

Yeah, what you say is what i expected for iframes. It makes sense that links inside the iframe would be considered internal links within the iframe provider's domain. As the entire contents of that iframe is within the shadow dom of that provider's domain.
I also just found this article:
https://cloudz.click/ugc/can-google-really-access-content-in-javascript-reallyWhich seems to indicate that google would crawl and recognize something like:
$('#3rd-party-content').append('');BUT only if the javascript that creates these links actually lives on the same domain i.e. not targetdomain.com!
Thanks for your help!

Hi there.
In short, Yes, iframes will pass link juice, but to the page, which is a source of iframe, not to pages, which are linked inside the iframe. And no, javascript created links are not passing rank flow.
When using iframe, basically what you are doing is you are pointing to the container on another website, and whatever is inside that container, it's hosted on that another website. That's why rank flows only to src link.
As for JS created links - they are considered hidden, devalued or obfuscated. Refer to this page on MOZ - https://cloudz.click/learn/seo/internal-link
Hope this helps.

Top hierarchy pages vs footer links vs header links
Hi All, We want to change some of the linking structure on our website. I think we are repeating some non-important pages at footer menu. So I want to move them as second hierarchy level pages and bring some important pages at footer menu. But I have confusion which pages will get more influence: Top menu or bottom menu or normal pages? What is the best place to link non-important pages; so the link juice will not get diluted by passing through these. And what is the right place for "keyword-pages" which must influence our rankings for such keywords? Again one thing to notice here is we cannot highlight pages which are created in keyword perspective in top menu. Thanks

Does Navigation Bar have an effect on the link juice and the number of internal links?
Hi Moz community, I am getting the "Avoid Too Many Internal Links" error from Moz for most of my pages and Google declared the max number as 100 internal links. However, most of my pages can't have internal links less than 100, since it is a commercial website and there are many categories that I have to show to my visitors by using the drop down navigation bar. Without counting the links in the navigation bar, the number of internal links is below 100. I am wondering if the navigation bar links affect the link juice and counted as internal links by Google. The Same question also applies to the links in the footer. Additionally, how about the products? I have hundreds of products in the category pages and even though I use pagination I still have many links in the category pages (probably more than 100 without even counting the navigation bar links). Does Google count the product links as internal links and how about the effect on the link juice? Here is the website if you want to take a look: http://www.goldstore.com.tr Thank you for your answers.

Why are bit.ly links being indexed and ranked by Google?
I did a quick search for "site:bit.ly" and it returns more than 10 million results. Given that bit.ly links are 301 redirects, why are they being indexed in Google and ranked according to their destination? I'm working on a similar project to bit.ly and I want to make sure I don't run into the same problem.

Link Juice + multiple links pointing to the same page
Scenario
Intermediate & Advanced SEO | | Mark_Ch
The website has a menu consisting of 4 links Home | Shoes | About Us | Contact Us Additionally within the body content we write about various shoe types. We create a link with the anchor text "Shoes" pointing to www.mydomain.co.uk/shoes In this simple example, we have 2 instances of the same link pointing to the same url location.
We have 4 unique links.
In total we have 5 on page links. Question
How many links would Google count as part of the link juice model?
How would the link juice be weighted in terms of percentages?
If changing the anchor text in the body content to say "fashion shoes" have a different impact? Any other advise or best practice would be appreciated. Thanks Mark0 -
How do I get 2 column Google sitelinks instead of one line sitelinks?
Currently, if you search for my site's brand name on Google, we are the top result. However, rather than having 2 columns of sitelinks, there is just one line of 4 sitelinks. When you search for the site's domain (sitename.com), you get the full 2 columns of sitelinks. Are there any strategies for getting the 2 columns on more than just the domain name search? At the very least, I'd like to get 2 columns to appear when you do a brand name search, but it'd be great to get 2 columns of sitelinks for our top search queries as well. Thanks for the advice...

Increasing Internal Links But Avoiding a Link Farm
I'm looking to create a page about Widgets and all of the more specific names for Widgets we sell: ABC Brand Widgets, XYZ Brand Widgets, Big Widgets, Small Widgets, Green Widgets, Blue Widgets, etc. I'd like my Widget page to give a brief explanation about each kind of Widget with a link deeper into my site that gives more detail and allows you to purchase. The problem is I have a lot of Widgets and this could get messy: ABC Green Widgets, Small XYZ Widgets, many combinations. I can see my Widget page teetering on being a link farm if I start throwing in all of these combos. So where should I stop? How much do I do? I've read more than 100 links on a page being considered a link farm, is that a hardline number or a general guideline?
