I found 2 sites with .edu domain and both are dofollow. Does it increase my pagerank if I get backlink fr0m them?
Keep in mind that just because they are .edu links they are not necessarily gold mines. If it's some student's subfolder website, the links probably aren't worth too much. The search engines would still treat that as essentially a separate website. Unless they have some links from the actual .edu website, the student website probably wouldn't be very strong. People have a false perception that all .edu links are good and that it is the .edu that makes these links good. All tlds are pretty much equal, but most .edu websites are well aged with lots of backlinks, making their links strong....provided that the link page is getting some of that site's link juice.
Where do you read those things can you please send me the link I'm just curious about .edu link,..thanks.
Most of are education related web sites even high PR, I guess no much value than a quality one way backlink.
Well if the link is coming directly from .edu homepage which has a good PR , then go for it otherwise if its a sub-domain or internal link place on some folder and not on homepage then check PR, if PR is not good it wont help as explained by vansterdam
I found the 2 sites dofollow on their guestbook. I think it is not a subdomain but subfolder. Any suggestions?
Are these links have PR, sometimes .edu guest books keep as a temporary one, check PR and out bound links.
Go For it Man! Shouldn't "hurt" you. If you're linking from a page that isn't as high the home PR, it should still be good page to link from regardless. I get a packet of High PR backlinks from Angela's Service every month and most links I get come from pages within High PR Sites. The the actual pages I'm linking from may not have the same PR compared to the Home PR, but even so the backlinks are very effective!
My university web site is PR8. I as a student have personal web site on the same domain. DO you mean that links from from there are worthless?
vansterdam is right on as usual... The one thing I would add is that though you might not get much PR from some .edu links, you might get other benefits as well from having .edu backlinks... .edu links likely pass your domain a lot of domain trust. It is said that when Google added domain trust to their algorithm that they picked a list of trusted domains (TDs). These likely included some .edus. Domains with links from the original list of trusted domains are considered highly trusted domains (HTD). Domains with links from the highly trusted domains might be considered moderately trusted domains (MTD)... etc. The key is the fewer hops you are away from the list of original trusted domains, the more 'trust' that is passed to your domain. Many .edus are likely in the TD or HTD list since many have been around since the begining of internet time and universities frequently interlink to one another because they might be part of the same state university system for instance. Also, it is said that the domain trust factor in Google's algorithm is a domain level factor and based on a domain to domain type link assessment... not URL to URL. So the domain trust factor likely gets applied to ALL URLs on the site similar to the domain age factor.
