Should I get specific backlinks for my whitehat SEO site? and different for my micro niche blog?
 


Backlinks all have different values according to most people on the web. One backlink from a PR4 site is worth more than two backlinks from PR2 sites. The authority of the site hosting the link gives the backlink its juice. This is why .gov and .edu sites are prized since they seem to be higher ranking pages and have fewer links going out.

Another theory is that each site only has a limited amount of linkjuice and each backlink posted on it takes away from the juice pile. In other words, linkfarms and forum profiles dont carry as much weight as a backlnk from a site that only has 50 outgoing links.

In the end, it is all theory since none of us work for Google and can not give you an answer based on fact.

Short answer: yes.
Long answer: It depends on your site's age, niche, current link velocity, current link profile, etc. on whether or not unrelated and different levels of authority links will make a difference for your website or not.

Partially true.

The authority of the site hosting the link gives the backlink its juice. This is why .gov and .edu sites are prized since they seem to be higher ranking pages and have fewer links going out.

Page Rank is a "general" indicator of a web page's worth in Google's eyes. What you see in the tool bar is rarely updated even though page rank changes daily. A snapshot of it use to be sent out to the Google toolbar every 3 months or so, but last year it didn't even get it that often.

PR of the root domain is only a general idea of its strength and authority, and should only be used as a general assumption of a link's worth. Getting 2 links on two different pages of that PR4 domain that have little to no PR themselves may or may not (usually not) do anything for you while getting 1 link on a page that has a PR of 4 on a PR2 domain may give you a lot of benefit.

Another theory is that each site only has a limited amount of linkjuice and each backlink posted on it takes away from the juice pile. In other words, linkfarms and forum profiles dont carry as much weight as a backlnk from a site that only has 50 outgoing links.

This is the more logical and correct assumption to make. It's always on the page-level though, not the site-level.

What you need to visualize is that a site has all these links pointing to it, from the site itself to other pages, and from other pages on other sites pointing to pages of its own site.

All those links share a certain context. The context is defined by many different things, and each Search Engine bot defines it deferently: anchor text of the link, text around the link relating to the anchor text, the text on the page receiving the link in relation to the anchor text of the link on the giving page, position of the link on the page, etc.

All of that works together to determine the strength of the page. Each link passes a certain amount of authority for certain keywords/categories. So, you'd get more authority passed if you put a link to your page about dogs on a blog page about miniature hairless poodles that has lots of links also about that and text on the page about that than if you put a link on their page to your page about computers.

In the end, it is all theory since none of us work for Google and can not give you an answer based on fact.

Yup. All you can do is test, test, and test some more - jotting down what you notice and trying to see how it all fits together to give you a better idea of how to take what you learn and apply it in other areas.
 
Interesting info on backlinks. My philosophy is to get as many links as you can from as many sources as you can as fast as you can, then rinse&repeat ;)
 
REXIBIT is on the money with this one. Although in my own experience, PR seems to be directly related to maturity. Links from higher PRs should transfer some google juice but, as stated, there are so many other parameters such as anchor text, LSI, etc. that I typically try to get from as many different sites as possible. Once the site starts to rank on page one the links start to build organically.
 
What about the relevance of the link to the site that the link is from? ie the site is about Apples but your link is about selling sneakers.

Anyone recommend buying/renting links on high PR homepages? Say PR4-PR6 with less than 200 OBLs.
 
Some backlinks are harmful if you have low number of backlinks. But if you have thousands of backlinks nothing can harm you at all.
 
I like to build parasites, web 2.0 sites that link to my main money site.

I then send thousands of high pr link to those web 2.0 links giving them more power in the SERPs whilst avoiding getting a big slap on my money site as im not spamming my own site.

Yeah, you want the links to be as relevant as possible. I'm not a fan of pricing links based on PR. The best way you can decide if a link is going to help is to see how the page ranks for terms related to yours.
 
It's important to balance out your backlink portfolio. You don't want more than 30% of your backlinks coming from sitewide links... or blog comments.. or forums.. - Mix it up. Use different anchors. Dont use the same username over and over again on the different sites.

Good luck.
