My question is two-fold. 1) Can anyone "recommend" the best Link Directory Submitter you have used and got "real" tangible results. 2) Submitting your links to a PR 2-3 or 4 Directory, does it mean that the (/sub) pages where your links are published are automatically PR 2-3 or 4 as well? Thank to all for your answers.
I can't help you with the first question. However regarding submitting to a directory - your main purpose is to list your site so that either one happens: 1) people visit your site directly from the directory (say a business directory) or ... 2) you get a strong backlink from an internal page WITH page rank. If you get links from a directory that has no internal page rank and nobody visits your site directly then there is no point in that link.
i have yet to find a perfect submitter, but you can find people who offer manual submission services here on dp. look for people with good reviews and ratings, etc.. this can help. your second question really just depends on the directory, but the sub category probably won't have the same PR as the main page. I would still go after the high PR directories first, since they could be considered more valuable for your seo efforts.
