As we all know, Google doesn’t tolerate when webmasters buy and sell links. Many paid directories were punished recently and Google removed many of them from index or decreased Pagerank. It is hard to tell which directory are going to be penalized… We can tell for sure that Google are not going to do anything with 3 of them and their power will remain the same:

1.  Yahoo Directory - only because it is Yahoo! Google count Yahoo Directory as business / marketplace and the fact that Yahoo charge for submission doesn’t even matter because it is a fee for advertising, submission review, approval process.
2. Business.com is another quality directory for companies and small businesses. Domain name tells everything.
3. BOTW - from 1994 this guys work with their directory to make sure that only quality websites appear their. Google doesn’t really want to destroy 14 years of experience and authority which BOTW gained.

 We always suggest our clients to add links in this directories.

 Why not others? Simply because 99% of paid directories don’t really care who they approve as long as webmaster pays money. Most of them is money making machine for people who wants to sit at home and click approve button once a week.

 Benefit of being listed in Yahoo, Business, and BOTW is incredible. Many webmasters use this directories to copy links and put on their websites when they provide resources. Listing could increase link popularity and website rankings in major search engines. Moreover, links from this directories pass pagerank and can increase Pagerank of your site as well.
