I have a website and I have linked with around 10 websites but then my PageRank still 0. Actually how many websites do I need to link, just to have at least 1 PageRank? I also did=> link:mywebsiteaddresshere but the result also zero.
There is no certain number of sites you need, its the amount of quality sites you get listed on. Some quick ones, well directories, that will def give you some PR. or at least quicker listing, are DMOZ, Joeant, Gimpsy, and Goguides.
If you linked (I mean external links pointing to you) very recently you will need to wait for the next PR update and if your not even listed yet, the spiders still have to find you. The last one was around the first week on this month. The more sites you have pointing to you, the quicker you will get listed, then eventually your PR will grow.
And an easy way to see PR is with the Google toolbar, which can also be used to see all your backlinks (hit the info button) from sites with a PR4 or above.
