Hello , I have 2 websites : one is 2 years old and page rank 2 ,the other one is almost 1 month and page rank 0. I would like to do SEO for these 2 websites. First full I want to start with web directories. What are the rules for posting ? For example if I post today 20 directories and 1 week later another 20, is it ok for Google? Someone said if I start to post 20 directories per day, I should post every day the same number ,otherwise Google can give me a penalty ? Is this right? If I don?t post every day with the same speed ,Google will give me the penalty ,and my website?s page rank will go down? Does anyone had this kind of experience with Google ? And another question : who give the Google penalty? Machine or human being ? Thank you for sharing your thoughts !
