Single Domain With Different Pages Deep Linking To Different Pages On External Domain

[stevenheron]

I've been partaking in an extensive trial study and will be releasing the results soon, however I do have quite a strong indication to the answer to this question but would like to see what everyone else thinks first, to see where the common industry mindset is at.

Let's say SiteA.com/page1.html is PR5 and links out to SiteB.com/page1.html

This of course would count as a valuable backlink.

Now, what would happen if SiteA.com/page2.html, which is also PR5, links out to SiteB.com/page2.html ?

The link from SiteA is coming from a different page, and is also pointing to a different deeplink on SiteB, however it will contain the same IP address.

What would the benefit be for having multiple deeplinks in this way (as outlined above, please read it carefully before responding) as opposed to having just a single deeplink from the domain?

If a benefit does exist, then does the benefit start to become trivial?

This has nothing to do with sitewide links. Serious answers only please.

I suspect that you will see page authority benefit on each page but that domain authority will be relatively unchanged.  But I don't think that is because of the IP address.   I think the fact that site A Pages 1 and 2 are on the same domain will be the bigger factor.  If you had a shared hosting solution with multiple domains that had significant domain authority (and who doesn't right?) I think you could get benefit from linking from each domain.

Interestingly, I just put the same test in the field about 8 hours ago.  I'll share my results with you as well.

Interesting analysis Jake.

Your response then opens another question, do inlinks from different domains on the same IP have the same value as inlinks from different subnets, and if they don't, then do the value of the links increase as the subnet becomes greater? (eg, a different class C subnet being better than just a different class D subnet etc).

If the IP address itself didn't matter, then would it be better to have two links from separate domains on the same IP, or two links from the same domain but on different subdomains with different IPs?

Look forward to your results too, as I haven't found a study where this has been properly analyzed to any great detail.

I wonder if the IP matters at all.  I have read "warnings" about being careful of shared hosting solutions due to the possibility of being characterized as being in a "bad neighborhood".

Unless someone has test data, I'm not ready to buy that unless the SE is classifying an entire geographic area as a bad neighborhood.  (Not a political discussion I think they'd really want to enter into.)  Systems admins regularly implement fail over an migration scenarios that involve websites being hosted at multiple IP addresses.  I can't imagine that the SE's penalize the website when an IP address change takes place in DNS.

I don't think the IP address is an effective way to identify the value of content though and given the complications I mentioned above I suspect the SE's would agree.  My bet is they ignore it for anything other than geolocation data.

I'm willing to be proven wrong for sure!

Interesting take on the matter. What are everyone elses thoughts?

Obviously no one here knows much about SEO. Oh well.
