Well, We were into natual search targetting since last few years where we thought Content is the king, which definetly is the truth till day.
But mixing Content is the King with PPC targetting and trustworthy site (since few years), we are seeing more then 500% + growth in just a few weeks. (maybe our keyword research on niche sectors is reason for few our our websites).
But we definetly are impressed with PPC.
Thanks to webmasterworld where I was able to convince myself and learn about same..
