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.

Can Google Bot View Links on a Wix Page?
Hi, The way Wix is configured you can't see any of the on-page links within the source code. Does anyone know if Google Bots still count the links on this page? Here is the page in question: https://www.ncresourcecenter.org/business-directory If you do think Google counts these links, can you please send me URL fetcher to prove that the links are crawlable? Thank you SO much for your help.

One domain or two for one company with two lines of business?
Let's say you are building a new company that is involved in two lines of business. Let's for example say one line of business is handling logistics for large conventions where the customer(s) are large corporation and the other line is for wedding planning. Let's say that for certain reasons the owner wants to operate under one brand name, say "PROEVENT" So they will market themselves as PROEVENT Convention Logistics and PROEVENT Wedding Planners. From an SEO perspective, if you have one side of the business doing B-to-B corporate business and the other doing B-to-C do you create two different websites on different domains (proeventconventions.com and proeventweddings.com) with unique design and content, or, do you just use provent.com in order to build better domain authority and on your marketing you use conventions.provent.com that takes you to the convention section of the website and weddings.provent.com takes you to the weddings section?

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

Link Research Tools - Detox Links
Hi, I was doing a little research on my link profile and came across a tool called "LinkRessearchTools.com". I bought a subscription and tried them out. Doing the report they advised a low risk but identified 78 Very High Risk to Deadly (are they venomous?) links, around 5% of total and advised removing them. They also advised of many suspicious and low risk links but these seem to be because they have no knowledge of them so default to a negative it seems. So before I do anything rash and start removing my Deadly links, I was wondering if anyone had a). used them and recommend them b). recommend detoxing removing the deadly links c). would there be any cases in which so called Deadly links being removed cause more problems than solve. Such as maintaining a normal looking profile as everyone would be likely to have bad links etc... (although my thinking may be out on that one...). What do you think? Adam

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...
