OK, but what if it won't bring much traffic? I'd like to know if it will help my site in its SERP on Google.
Ofcourse it is. Forget about the PR when judging the quality of a link and focus on things that are really important (relevancy of the site/page, anchor text, page optimisation, domain age.....etc).
Yeah even an P0 link is very usefull.. if the link is do-follow or now.. it doesn't matter. Google will find it anyway and reward you for it .. Every link is usefull if it's P0 of P9 it realy doesn't matter.. if the link is quality ofcourse and not a spammy link.. Hope this solves your question..
Yes dear hundred per cent. PR 0 link on related site is far better than High PR unrelated site. Google at first sees relevancy then any other thing. Go on
It will help you in getting a backlink, but it won't help in increasing your pr. If your site's pr is higher than 0, then it can result in decrement of your site's pr.
Think of it this way that it is a relevant backlink and not causing your site any harm at all keep building links and you will see the benefit eventually
A link is just another link. All links work. But not all links last. And the value of any link is determined by the length of time it remains active and in place.
If link is related to your niche and connected to direct index page that pr0 links are helpful to boost site.
