Hi Friends Three months before My client gave 5 keywords For SEO, when i analyze the keyword in Google keyword tool, search volume for that 5 keyword was nothing (i.e Zero). But now i got 300 visitors per month how it is possible?
Sometime you may getting traffic from referral methods. Also Google traffic volume is not 100% accurate. It just help you to get an idea.
i think you have done some submissions in different directory sites. or just after crawling your site Google placed your site at a good position for its good quality contents. both are possible. thanks
