Hi - what is more important the page rank of a backlink or the amount of class C ip's linking to it? As sometimes i see a website with 10 class c backlinks with a PR of 4 and then a PR3 with 110 class c backlinks? Rich
Both hold value. There are too many factors. The right approach to take is get backlinks from wherever you can, as a link can't have a negative effect. There are so many factors; PR, relative subject, how authorotive the linking site is etc. That's my opinion anyway.
Yeah as stated above there are lots of factors involved in getting the best links. Some things to take into consideration are: Page PR Domain PR Age of domain inbound links (and quality of them) outbound links of page and site content on the website relevancy of your page to the linking page The list goes on and on but basically if you can get a link get it. No link is a bad link and most links will help.
The two posters above are absolutely right. However, you might want to avoid posting too many links at once (hundreds or thousands) on not-ranked domains. Search engines could consider these links spammy.
You can't just go by one or the other...search engines look for a lot of points... have to be good with both
