Is there any data available on how deeplinking contribute to improve domain authority?

[max.favilli]

Let's say you are collecting backlinks across a variety of pages for foo.com, like: foo.com/clown, foo.com/juggler, foo.com/lion-tamer and so on...

Page Authority will benefit for each of those pages, but what is going to happen to Domain Authority?

Is there any data available? Any educated guess in what's the best strategy to try to get best results for both PA and DA?

[metafser]

When you are collecting backlink from those page, then you said, i got PA benifit, what's DA ? Now qestion to you ? Why you think, Is there no benifit for your DA ?

By the way, when i worked that kind of work, i saw that, its increasing both point. Quality Backlink are always give you good DA & PA.. But remove toxic backlinks. Be patitent.

I know DA is increasing as well. I can see that. But I have no idea of what correlations are there. And if there's any best practice or strategy to maximize benefit for both.

I got a nice comment from Matt-Williamson. I also agree with it. You can follow it. I think, it will help you.

"To increase your Domain and Page Authority you need to increase links to your website and in particular your homepage if you want to increase that specifically. To do this you need to think how can you create some decent content that is link worthy and then you need to make sure it gains exposure so that it will start to gain links. There are lots of ways that you can increase your link profile using things such as:

• In depth product reviews,
• A blog (consider encouraging and rewarding guest bloggers that are authorities in your niche as they will have a strong, relevant following),
• How to videos in relation to your products and how they might come in when carrying out a task for instance,
• Content curation is also an idea (some decent articles on this on SEOMoz).

Now for the exposure; best place to start is to build up your social networks and start to interact and form relationships with people that are likely to have an interest in your products, in particular those that are authorities in your niche/product area. Then when you have built relationships with them you can expose them to your new content, which will then hopefully get passed on to their social following and through this you will start to gain links and more attention slowly establishing yourself as an authority in the process - win win situation!

If you do this and work hard at it your DA and PA will increase as you want it to. Just remember that when you are building links in a post penguin world don't over do the anchor text and always go for quality links over quantity, don't start using dangerous methods, such as forum signature and blog comments. Hope this helps - Good Luck!" Beside I will say, you can try this small strategy, Cause i am using this strategy, it helped me for increasing Both point.

1. Comment on Relevant Authority Blogs
2. Update Your Blog Regularly 
3. Increase Indexed Pages 4. Increase Backlinks
5. Increase social signal.

Maybe my question is not clear enough. I am not asking about a strategy to get backlinks. I know how to get backlinks.

What I don't know is if there's any analysis, study, data, test... Supporting any particular strategy on how to diversify backlinks among home and internal pages.

In other words, to be more clear... Let's make two examples (just for the sake of being understood).

Is there any analysis, study, data, anything... Saying that is generally better to have 50% of backlinks to homepage and 50% to internal pages. Or is better to have 90% of backlinks to homepage and 10% to internal pages, etc...

[metafser]

Got it now clearly. Ok I am going to answer your question from my little brain. It will better if you use 60% + home page linking, or inner page 20-30% is enough. Its really tough to give you exact data analysis. I know its not enough for you. But I tried to give you something.

In this whiteboard friday Rand is addressing this topic, and it's interesting that many (diverse) deep-links from same domain are quite valuable.

But yet I can't find any clue about the effect on DA.

Ciao Massimiliano

It depends on what you mean by "Domain Authority/DA." If you meant the DA score in Moz's tools, that's primarily impacted by the Page Authority of the collection of pages on the site (which, in turn, are affected by external links that point to them). The more links to any page on a domain, the higher DA typically rises.

If you're talking about the broader concept of Domain Authority as it relates to SEO, there are many more elements that likely figure into how Google calculates a site's importance and its relative authority/relevance in a particular space. Certainly a large part of that is still links, but visit data (from Chrome, Android, ads, etc), search data (branded searches, search traffic sent to the site, relative satisfaction of search visitors, etc), and others (stuff around entities, citations, brand name usage, social media, etc) probably make it into the algorithm in one way or another (sometimes indirectly).

Hope that's helpful!

Hi Rand,

it's helpful.

But I can narrow my doubts/question to this: what is a safe range for the ratio of deeplinks vs rootlinks to get the best results?

If a website is getting a lot of deeplinks and few links to the root domain, google could perceive those pages as highly relevant but do not reward the domain as a whole?

I know what you are thinking, since google algo is not on github, we don't know exactly.

But if you at MOZ calculate DA as you explained, is probably because you think google is doing something similar, and thus rewarding a domain as a whole for it's deeplinks?

Hence, in terms of the broader SEO concept of Domain Authority, should we assume a website with 0 rootlinks and many deeplinks is getting a similar authority as if it had all rootlinks?

I know this is highly speculative, that's why at the beginning I was asking if anyone had some data/analysis on this subject.

Thanks a lot of your time!

In order to truly test this at scale, you'd need a very large number of sites and a huge swath of testable, organic linking sites - probably not feasible.

However, I can tell you that IMO, it doesn't matter much. If the links are organic and editorial, Google probably doesn't care whether they point to deep pages or the homepage. Some sites get a lot of press, which means they get links to their homepage. Other sites have lots of links to their content, which means they get deep links. I honestly doubt Google cares much which it is - what matters more is the quality and editorial nature of the linking sources.

Your opinion is reassuring. Thanks.
