Hey, Personally, I don't believe that matters. I believe it matters more about how closely related the site is too yours & it's rank in search engines. If it has a good ranks then all the back links from that site will provide some nice link juice. I have been building back links for all the closely related sites I enjoy & I am already seeing the benefit to what I'm doing. It's just one of those things you learn more about once you get into it. Just my 2 cents. God bless, William Veasley
the quality of the backlinks is related to the page rank of the site you comment on. I use SEO quake the Firefox add-on to check the page rank of the site. SEOquake also indexes the sites that are backlinking to it so you have source of other sites to get your own backlinks
The more outbound links the more juice it will share between them. Google will not give more juice for duplicate links. Let's say there's 3 sites. site1.com site2.com site3.com Each one of them gets 33% of the juice. (Technically) Let's say there's site1.com site1.com site1.com site2.com site3.com You still get 33% juice. Let's say there's site1.com site1.com site1.com site2.com site2.com site2.com site3.com site4.com Now you get 25% of the juice, even though there's 8 links. Of course a ton of other variables come into play, including the relevancy, anchor text, etc.
I think it depends on the authority of the websites you're linking to as well. I have over 70 websites, and I've done a lot of testing. I'd never put more than 5 external links on a page regardless
I have to agree with this. Sites that dont have many links ie Local User Sites are much better than submitting to link farms just to get a link.
If you're using Wordpress, you can also use a no-follow plugin to reduce the amount of link juice flowing out.
I have heard that it's best to make sure there are less than 30 OBL's per page, but that was from only one source and in the SEO world there are a ton of mixed opinions.
not only OBL matter, the page quality also matter link from: PR 5, 500 OBL is better than PR 0, 10 OBL
