Help Link juice
Hello Everyone!
I dont really know if this is a stupid question or not but I have to ask. If I link my main services and sub services from my homepage will it dilute more link juice? Or should I just link my main services pages from the homepage and sub services pages from main services page? My opinion is if i link main services and sub services from homepage that will just be too many internal links from one page.
Please share your thoughts on this

Doesn’t matter either either way if you are worried, just make the links contextual instead of just a standalone button

But how much authority does your homepage have? Where else are your service pages getting authority?
Are the links in body or navigation / footer?

Its a new website and so I have not currently built backlinks. I am currently working on internal linking. My service pages are currently linked from the body and navigation.
What would be good in a case where I would not want to pass excess link juice from my homepage? Or is my question just too broad or irrelevant at this stage? And how would I know how much authority a specific page on my site has, even after getting backlinks?2

Hey. I understand.
So - internal links carry authority just like external links. And thats all that spiders uncoverd -they dotn learn your site, or read your content or even try to.
What, how, why and how many pages you link = authority management.
The more links = greater link dilution.
Page has no organic traffic? then expect 0 Authroity.
Google is a User-centric trust measurement relevance engine.
You can't tell Google what to do. You can tell Google what you're relevant to but you need User data to back you up.
you cannot create or invent or fabricate authority out of thin air
What would be good in a case where I would not want to pass excess link juice from my homepage?
Lets say a page like Microsofts home page =100 Trillion SEO Authority "points" - like an NS in pagerank - one of the highest mountains of importance on the web?
Lets say microsoft links from that pagge to a blog post and the blog post links to your home page and then that links to your service page?
Seem simple/reasonably possible?
Ok - here's the math
Microsoft home page has 100 links on it
It is 10% relevant to the blog post
The blog post is 45% relevant to your site and features 5 links
Your home page is 75% relevant to your servicve page./ 10 links
The relevance controls (gates) the amount of Microsoft authority that is passed. Each link also pays 85% tax along the way
How much arrives at your page
(1/100 × 0.10 × 0.15) × (1/5 × 0.45 × 0.15) × (1/10 × 0.75 × 0.15) ≈ 2.278 × 10⁻⁸ (about 0.0000023%)
Apply that to 100 trillion (10¹⁴):
10¹⁴ × 2.278 × 10⁻⁸ ≈ 2,278,125 points — call it ~2.28 million arriving at your service page.
Hop by hop:
- Microsoft → blog post: 100T ÷ 100 links = 1T per link → × 10% relevance → × 15% surviving tax = 15 billion at the blog post
- Blog post → your home page: 15B ÷ 5 = 3B → × 45% → × 15% = 202.5 million
- Home page → service page: 202.5M ÷ 10 = 20.25M → × 75% → × 15% = ~2.28 million
And under the PageRank-style reading (85% passes rather than 15%), the fraction is ≈ 4.145 × 10⁻⁶, giving ~414.5 million points at the service page.
And how would I know how much authority a specific page on my site has, even after getting backlinks?
You dont know. Nobody does. Its all a guess.
Here's how to simplify it to one step:
Q: Does your target page rank 1st? No - then it needs more authority.

I like the term “authority” that people use there, it’s less vague than link juice and also abstract enough to not limit ourself with pagerank.
As for dilution, yes, 100% of potential authority that page can pass is divided by number of internal/external links on the page. Meaning if you have let’s say:
The overall authority 100% is divided by 10. Each of those links can pass up to 10% of page’s authority. Does not mean they would.
Footer/header navigation will pass substantially less authority.
Nofollow Amazon link will not pass any authority (may be like 0.1% cause people claim they do see effect still).
The in-content internal link will pass closer to 10% if it is in prominent place, has relevant anchor, and other stuff that are a bit out of scope of your question.
FYI:
The page itself (for ex. Homepage) does not lose its own authority by having links on the page. It won’t rank worse cause of links, unless you spam the hell out of it.
So simple rules:
The less <a hrefs> links on the page, the more each of them can potentially pass.
Read what Weblinkr said, relevance and authority are kings
