How much effect does number of outbound links have on link juice?
-
I am interested in your thoughts on the effect of number of outbound links (obls) on link juice passed? ie If a page linking to you has a high number of obls, how do you compute the effect of these obls and relative negative effect on linkjuice.
In the event that there are three sites on which you have been offered the opportunity of a link
Site A PA 30 DA50 Obls on page 10
Site B PA 40 DA50 Obls on page 15
Site C PA 50 DA50 Obls on page 20
How would you appraise each of these prospective page links (ignoring anchor text, relevancy, etc which will be constant)
Is there a rule of thumb on how to compare the linkjuice passed from a site relative to its PA and the number of obls? Is it as simple as page with 10 obls passes 10x juice of page with 100 obls?

In my experience links on highly trusted sites are more valuable than links on low quality sites. I wouldn't stress too much about the number of outbound links on a page. An authoritative and editorial link on harvard.edu would be more valuable with 100 other OBL than a link on a lower trust site/page with only 10 obl. Of course this is only my opinion, many people disagree with me.

I understand what you're saying. It can be a great deal of work getting a link from someone and you want to find an exact way of rating one over the other. But I think you have to factor in all of the other context factors.
I know from Rand and others' comments that a low PA/High DA link is favorable compared to a High PA/Low DA link. And I believe the PA score is affected by the number of outgoing links (Not 100% sure). This would mean that DA is a larger factor than the number of outgoing links.

I am interested in how the number of outbound links from a page linking to me might affect how much link juice is passed to me? As regards variables youre quite right I just wanted to keep that out of the calculation.
As regards 'opportunity' perhaps its more appropriate to see this Q as to help decide which site you should put your efforts into getting a link from. If a great site with PA/DA of 70/80 has 50 obls on the page youre likely to gain a link would you be better going after a link on a site of PA/DA of 35/40 with only 10 obls on the page?

I believe you are talking about inbound links. Links to you.
"In the event that there are three sites on which you have been offered the opportunity of a link"
To answer your question: I don't believe so. It's not as simple as counting the number of links on a page. You also have to factor in link placement. Top of the page vs. bottom of the page. And while you want to hold the other factors constant, anchor text, relevancy, etc., they will never be constant. There are always variables involved.

Broken URL Links
Hi everyone, I have a question regarding broken URL links on my website. Late last year I move my site from an old platform to Shopify, and now have broken URL links giving out 4xx errors. When I look at Moz Pro>Campaigns>Insights>links, I can see the top broken URL links, however there is a difference if copy & paste URL directly from Moz Pro and by Export CSV file. For example below, If I copy and paste links direct from Moz Pro, it has the “http://” in front as below: http://www.thehairhub.com.au/WebRoot/ecshared01/Shops/thehairhub/57F3/1D8F/D244/C675/E27D/AC10/003F/35AD/manic-panic-colours.jpg But when I export the list of links as an CSV file, the http:// is removed. www.thehairhub.com.au/WebRoot/ecshared01/Shops/thehairhub/57F3/1D8F/D244/C675/E27D/AC10/003F/35AD/manic-panic-colours.jpg Another Example below: By copy & paste URL direct from Moz Pro

http://thehairhub.com.au/Shop-Brands/Vitafive-CPR/CPR-Rescue By export CSV file.
thehairhub.com.au/Shop-Brands/Vitafive-CPR/CPR-Rescue Which one do I use to enter into the “Redirect From” field in Shopify URL Redirects? Do I need to have the http:// in front of the URL? Or is it not required for redirects to work? Kind Regards, John Wall

Effects of significant cross linking between subdomains
A client has noticed in recent months that their traffic from organic search has been declining, little by little. They have a large ecommerce site with several different categories of product - each product type has its own subdomain. They have some big megamenus going on, and the end result is that if you look in their Webmaster Tools for one of their subdomains, under Links to your Site, it says they have nearly 22 million links from their own domain! Client is wondering if this is what is causing the decline in traffic and wondering whether to change the whole structure of their site. Interested to hear the thoughts of the community on this one!

Finding Broken Back Links
Hello there I am new here but really want to mend my broken website by myself as I enjoy a challenge! I used to have great rankings but have moved websites a few times (same domain) and the last move was to wordpress. I now have loads of broken links in the SERPS and wondered if there was an easy way to flush google of them as they are getting lots of 404 errors? They really are too many to do a 301 on (I have done the main pages) Also how do I do a crawl of my website for any internal broken links? Does SEOmoz have something or is there an external program you would recommend? Thanks Victoria

Page for Link Building
Hello Guys, My question is about a link building process. We all know that some directories/sites do require a reciprocal link. Does it make any sense to creat a page in website exclusively to reciprocal links? And what we do with this webpage in terms of indexing, do folow, crawling...etc. Any sugestions are more then welcome 🙂 Tks in advance! PP

Optimum Number of Links on Any Given Page
One of the guidelines you provide stipulates: "You should avoid having too many (roughly defined as more than 100) hyperlinks on any given page. When search engine spiders crawl the Internet they are limited by technology resources and are only able to crawl a certain number of links per webpage. In addition, search engine algorithms divide the value of some popularity metrics by the amount of links on a given page. This means that each of the pages being linked to from a given page are also affected by the number of links on the linking page. For these reasons, we recommend you include less than 100 links per page to ensure that they are all crawled, though if your pages have a high page authority, search engines will usually follow more links." As far as these 100 links are concerned, is this in reference to ALL links including outbound, internal, etc? Or is this referring to only outbound links to other sites?
