Due to the abusive approach of Blackhat SEO guys to directory submission sites, Google, a leading search engine on the Internet has started to ignore links coming from Directory websites and decrease the Pagerank of websites that have been exagerratedly linking to directory submission sites and worst, penalized a website from their database. Because of their guidelines, Google can penalize a website that they believe performing Blackhat SEO or unethical link building technique.
As a result of Google's action, SEO firms do not perform a website submission on directory sites for the websites that have been over optimized on directory submission sites. They also believe that linking into directory sites will not increase the performance of their websites and it may possibly harm their sites in the future.
