Domain authority vs indexed pages

[maxdelop]

Hello,

There are many articles and from our personal experience we can say that you can rank a page without backlinks with high DA but we cant figure out if DA of domain help to rank as the link juice ( so the link juice going from home page thru all pages to specific page)  or it will rank a page even if its not linked in any way from homepage or any other pages and even if it not linked in any way from other pages and still ranks just because of high DA, does that DA value will spread even above all indexed pages if you have lets say 100,000 pages, i mean if domain has 100 indexed pages and DA of 50 and another domain has 100,000 and DA of 100, if both pages are the same on those domains and have no backlinks to it from my understanding page on domain with 100 indexed pages and DA of 50 suppose to rank higher ?

Please share what you think

Hi Andi!

I'm not so sure the division of DA across pages on a domain is that cut-and-dry. It's not some finite material that can only be divided among so many pages, and a page's Page Authority can differ from its domain's Domain authority radically. Remember, also, that Domain Authority is a proprietary Moz metric measuring, primarily, a domain's overall link strength. It _approximates _Google's ranking algorithm, but it doesn't nail it exactly.

In addition, the lack of backlinks to that page in Open Site Explorer doesn't mean that page has no backlinks. For a dynamically-generated page like that it's much more likely that OSE simply hasn't seen it. Remember, OSE doesn't necessarily crawl every page on a site, and that's especially true for particularly deep pages.

Frankly, I would expect that the page on the larger site with DA 94 would do better than a page on a smaller site with DA 50. The DA 94 implies a much stronger site.

Hi,

Thanks for reply , but I think I wasnt specific enough so i want to provide you good example:

keyword: no credit check apartments las vegas

1st position in Google:

http://www.yelp.com/search?find_desc=No+Credit+Check+Apartments&find_loc=Las+Vegas%2C+NV

that is one of those generated pages from user search terms, i checked the site structure and i can not see any internal links pointing to this page, I checked ahrefs and moz and no external links either. So we can assume that this page gets only benefits from Domain Authority. Check domain yelp.com it has DA of 94 and has 40 millions indexed pages in Google. So

1st Question: If this domain have instead of 4,000,000 indexed pages lets say 400,000,000 would that page still gets benefit from DA ? and if it would does that mean that it doesnt matter how many indexed pages they got and if they will create 400,000,000 pages then they would just cover half of search results with their pages . My answer on this question would be NO , from common sense it is understandable that Google wouldnt let them do that and Google probably would take that Domain Authority and spread the power of it across all pages equal. Am I right ?

2nd Question: So if I am right on previous question then how we can compare the power of page A from domain A which have 100,000 indexed pages and DA 94 against page B on domain B which have 10 indexed pages and DA of 50 ?  Which one do you think will be stronger ?

Please share your opinions on 2nd Question , who would vote for page A or page B ?

I want to find golden middle to understand how many indexed pages we could have on domain C with less DA (lets say DA50)  than domain A(DA94) so we would have enough power to outrank page A and at the same time have maximum number of those user generated pages.

Hello Andi,

I think there is some confusion here "you can rank a page without backlinks with high DA".

Actually, Domain Authority is calculated with number of factors and backlinks is the most important one. So, if the DA of any page is high, it means that domain is getting good links.

Refer this guide for DA:
https://moz.com/learn/seo/domain-authority If a Domain has good authority, yes the other indexed pages will get the benefit. For judging the worth of other indexed pages, there is another scale called "Page Authority" which tells you how that particular page will gonna perform in search engines.

Refer this guide for PA:
https://moz.com/learn/seo/page-authority

Hope this helps!
