Multiple on-page links to single domain
-
Hi,
the main focus of my question is to add a bit more information to my client as to where they are going wrong.
Firstly they have a directory on a third party domain with subdirectories containing all their product listings. All the links need to be no-follow for sure.
However, from a link juice passing perspective if there are per page say 20-30 links to varying URLs on the same domain is it still the same sort of calculation that the link juice is sufficiently weakened that each link has little value, or because the links are to the same domain there is an extra (potential) filter going on?

I'm going to take the easy way out and side-step the topic of PageRank, which Alan covers well, and raise the issue of relevance and weighting based on reasonable surfer assumptions.
Generally speaking,
- the first link on a page passes the most relevance, and
- links from unique domains pass more equity than links from previously linking sites. Meaning each new link from the same domain doesn't pass as much equity as the first link from that domain. It's the law of diminishing returns. http://moz.com/blog/10-illustrations-on-search-engines-valuation-of-links
From a practical point of view, I try to get the highest link on a page. After that, I don't worry too much about additional links to the same domain on that page. But there are a lot of factors that play into this, and your situation may differ.

no don't think so.
Going by the original algorithm this is what would happen. and all testing I have seen since then show page rank flows much the same way still.
When we say 100% that is 100% of the PR it had to pass, as only 85% of PR is passed, http://thatsit.com.au/seo/tutorials/a-simple-explanation-of-pagerank
Imagine the page has only one link, then 100% would pass to that one page, would google weaken it? then why weaken it if passed to 5 pages?

So external links (pretending these are the only links) on the page
link 1 example.com/spam1.html
link 2 example.com/spam2.html
link 3 example.com/spam3.html
link 4 example.com/spam4.html
link 5 example.com/spam5.html
would not pass 100% link juice surely? Google would pick this up as unnatural and weaken them?

Imaging a page with 5 links
link1 to domainA
link2 to domainA
link3 to domainA
link4 to domainB
link5 to domainB "no follow"
60% of link juice will go to domainA
20% will go to domainB
20% will be wasted (no-follow)
The link text for link1 and link4 will pass link text relevancy, the other link text will not pass any relevancy.
Its a bit more complicated than this because the first link passed a bit more then the last.

Backlinks vs multiple domains
Hello, Our main website is setup on a .com domain and a .ca is setup as a 301 Permanent redirection to the .com. We just signed up to Majestic and found that we had a bunch of backlink linking to the .ca instead of the .com. My question is, is the SEO juice (for DA) being passed by from the .ca to the .com or I should start contacting those websites to get the backlink changed to .com? Thanks

301 redirect lost page authority & total links how ensure it passes on.
hello, I recently changed from www to non www. I have redirected my whole website so if I type www. it goes to the non-www page. doing a open site explorer I noticed my www. still has the page authority 14/100 with 6 links. where as the non-www page has 1/100 page authority and no links. how do I get the www. to mirror the non-www links?

eg if you goto http://www.finnmoto.com.au/mens-motorcycle-kevlar-hoodie/ it will goto the non-www version automatically, so why does the non-www replicate the page authority / total links attached picture for reference.
Google webmaster has been selected for non-www, its been about 2 weeks.
my domain authority i think about about 21 or more now its 19 aswell. I have a feeling:
nofollow or rel=canonical has something to do with it but Ill need read into what that does and how to apply. any ideas? uRiJ2Ul.png?10 -
Links from highly relevant but low Domain Authority sites: Yes or No?
We're reaching out to companies that we have a business relationship with (past and present) to find out if they would be interested in linking to us.

All are obviously in the same industry so highly relevant. But some of the sites are low in Domain Authority (with scores of about 15-25).
Should we also ask these sites -- or avoid them?0 -

Would you advise removing a "links" page?
I'm doing a site audit for someone and they have a links page full of reciprocal links for other similar businesses across the country. My gut instinct is to remove this page. How would you approach this if this was your client?

Linkbuilding from sites with lower Domain Authority and Page Rank than mine?
I have decided to approach all my suppliers and ask them for a link. If their site has a lower PR/DA than mine (PR4, DA43) is is it still worth asking them from a link, given the time that needs to be invested in this type of link building?

Is there a way to optimize our other domains for our primary domain?
Hi guys, At the moment we have our main website that is at .com We have also bought all the other domains that are available, such as: org.uk, .jp, .it, .mobi, co.nz, co.za, com.au, .cn and .eu Is there a way we can make these domains work for us a bit more? Currently they all just redirect to .com. Would it be better to put a holding page with a link to us and then a redirect on?
