I work for close to 3-4 hours everyday building links. In this, I manage to get link from 2-3 PR 4+ websites, manage to get linked on 2-3 PR 4+ forums. The pages I get links on is not PR 4+, but their homepage is, and the page my link appears is linked from the home page. Do you think this is good enough? How many backlinks do you manage to gain in a day and what quality links are they?
What niche is your site in mate? How many backlinks has it got in relation to your competitors? For some sites we build 2 - 3 GOOD links a week. For other we'll build 100's - depends on the competition really
It depends ont he quality of your links and what you are doing to build them. If they are highly targeted links then that is good. However, if they are random links not related what to do you need to use your time much more efficiently.
I heard from all people that the safe limit is below 100 a day for an old site that already has many backlinks. If it is a new site, then should be 10 links a day. I don't know where those figures come from but as I said it's just what people said. Please correct me if I'm wrong!
Sorry to say, but if your link is not on a PR4 page, then you are not getting the benefit of a link from a PR4 page. Perhaps eventually, since the homepage links to it, it my be assigned PR, and you may get SEO benifits from it, but for now, they are not providing much SEO benifit at all.
Don't forget to develop backlink from authorized site also, authorized site like article directories,social bookmarking,directories and any web 2.0 related website will help you on generate a good and natural backlink for a long term.
One site is generic - pretty much on all topics and another is into technology. By the way, know what, I got linked by a PR 8 yesterday..woohoo.. I think you are wrong..Matt Cutts actually made this point recently that it is more valuable if you get linked by a PR 0 inner page of a PR 6 website than if you get linked on the homepage from a PR 2 website..
I can see certain situations where this is possible. For example, if the pr2 has over 100 outbound links on it already, then it passes next to nothing. A pr0 page within a PR6 page also passes next to nothing. Over the long run though (3-6 months), that pr0 from the pr6 may have some pr assigned to it, especially if it is linked to directly from the homepage. But for immediate impact, a PR0 is still a pr0, and yields next to nothing in terms of SEO benefit.
