Do more links from sub-domains to domain (website) hurt rankings?

[vtmoz]

Hi all,

If there are multiple sub-domains like abc.website.com, 123.website.com, etc...and if the top pages of website are linked from multiple sub-domains via top menu or footer links; will this hurts?

Will too much interlinking of few top pages of a website from it's sub-domains dilute link juice?

How many links ideally we can add to website from a sub-domain?

Thanks

Hi there,

There isn't a definitive answer regarding the number of links that you should add. The way I'd suggest thinking about this is what would make sense for users - do they need to have links on every single page? Does it make sense for them to be able to click to different subdomains from anywhere or could you list them all on your homepage or another page?

It's pretty common practice to cross link between subdomains that are related to each other, but you do want to be careful not to do it if it doesn't make sense i.e. if you're doing it just for SEO benefit, it's worth considering if it's the right thing to do. It's also worth avoiding a focus on keyword driven anchor text, because that could definitely be seen as manipulative if you overdo it.

I hope that helps!
