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!

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://moz.com/learn/seo/internal-link
Hope this helps.

How Many Links to Disavow at Once When Link Profile is Very Spammy?
We are using link detox (Link Research Tools) to evaluate our domain for bad links. We ran a Domain-wide Link Detox Risk report. The reports showed a "High Domain DETOX RISK" with the following results: -42% (292) of backlinks with a high or above average detox risk
Intermediate & Advanced SEO | | Kingalan1
-8% (52) of backlinks with an average of below above average detox risk
-12% (81) of backlinks with a low or very low detox risk
-38% (264) of backlinks were reported as disavowed. This look like a pretty bad link profile. Additionally, more than 500 of the 689 backlinks are "404 Not Found", "403 Forbidden", "410 Gone", "503 Service Unavailable". Is it safe to disavow these? Could Google be penalizing us for them> I would like to disavow the bad links, however my concern is that there are so few good links that removing bad links will kill link juice and really damage our ranking and traffic. The site still ranks for terms that are not very competitive. We receive about 230 organic visits a week. Assuming we need to disavow about 292 links, would it be safer to disavow 25 per month while we are building new links so we do not radically shift the link profile all at once? Also, many of the bad links are 404 errors or page not found errors. Would it be OK to run a disavow of these all at once? Any risk to that? Would we be better just to build links and leave the bad links ups? Alternatively, would disavowing the bad links potentially help our traffic? It just seems risky because the overwhelming majority of links are bad.0 -
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.

"Null" appearing as top keyword in "Content Keywords" under Google index in Google Search Console
Hi, "Null" is appearing as top keyword in Google search console > Google Index > Content Keywords for our site http://goo.gl/cKaQ4K . We do not use "null" as keyword on site. We are not able to find why Google is treating "null" as a keyword for our site. Is anyone facing such issue. Thanks & Regards

Will Google View Using Google Translate As Duplicate?
If I have a page in English, which exist on 100 other websites, we have a case where my website has duplicate content. What if I use Google Translate to translate the page from English to Japanese, as the only website doing this translation will my page get credit for producing original content? Or, will Google view my page as duplicate content, because Google can tell it is translated from an original English page, which runs on 100+ different websites, since Google Translate is Google's own software?

Redirecting one site to another for link juice
I have two sites with same theme - buying cars. I am going remove one of the sites from being crawled permenantly (ie junkthecars.com) and point domian via 301, to another similar theme site (sellthecars.com). The purpose is to simply pass the SEO link juice from one site to the other as we retire junkthecars.com.... Is a forwarding of the domain OK and the best way for the search engines to increase the rank of sellthecars.com (we hate to wast the link work done on Junkthecars.com)? What dangers should I look for that could hurt sellthecars.com if we do the redirect at a simple TLD?

Site wide footer links vs. single link for websites we design
I’ve been running a web design business for the past 5 years, 90% or more of the websites we build have a “web design by” link in the footer which links back to us using just our brand name or the full “web design by brand name” anchor text. I’m fully aware that site-wide footer links arent doing me much good in terms of SEO, but what Im curious to know is could they be hurting me? More specifically I’m wondering if I should do anything about the existing links or change my ways for all new projects, currently we’re still rolling them out with the site-wide footer links. I know that all other things being equal (1 link from 10 domains > 10 links from 1 domain) but is (1 link from 10 domains > 100 links from 10 domains)? I’ve got a lot of branded anchor text, which balances out my exact match and partial match keyword anchors from other link building nicely. Another thing to consider is that we host many of our clients which means there are quite a few on the same server with a shared IP. Should I? 1.) Go back into as many of the sites as I can and remove the link from all pages except the home page or a decent PA sub page- keeping a single link from the domain. 2.) Leave all the old stuff alone but start using the single link method on new sites. 3.) Scratch the site credit and just insert an exact-match anchor link in the body of the home page and hide with with CSS like my top competitor seems to be doing quite successfully. (kidding of course.... but my competitor really is doing this.)

10,000+ links from one site per URL--is this hurting us?
We manage content for a partner site, and since much of their content is similar to ours, we canonicalized their content to ours. As a result, some URLs have anything from 1,000,000 inbound links / URL to 10,000+ links / URL --all from the same domain. We've noticed a 10% decline in traffic since this showed up in our webmasters account & were wondering if we should nofollow these links?
