If I get a link from a related blog for my site, but the blog already has too many links in its blogroll - about 15, can this hurt my site? The site is PR6. Maybe it will help only a little, but it can't hurt my site I think, can it?
Hmm, a blogroll link is obviously just the same as a sitewide link. I'd request that the blogroll link is given a 'nofollow' attribute at the very least. I installed it on my new blog as I watched a video of a guy install it, he had PR5 and PR6 sites linked to each other..and they all went to PR0, so he created the nofollow plugin
No absolutely not. if you read Google's patent you will see that blogroll links are actually a preferred methods for them to rank new sites. Also, the number if links on a page won't hurt you. , but the relevance of those links will.
number of links dont hurt you, but the value they pass in terms of PR is much less in comparison to blogs with less number of roll links
Yes, if you can get your site linked to from a related PR6, jump on that like there's no tomorrow. A link is a link... and I am jealous you are able to get a related PR6. Nice link building!!!
Getting links on a blog will not hurt your site, this is considered as a white hat seo technique which google encourages.
