Hello there, I am very new to marketing. If anybody can explain how to use PPC for getting traffic and leads, that'd be a great help. Thanks in advance.
What's there to explain? You write, put together interesting ads, and place them in other webmasters' sites or in the search engines, like, Google (Adwords).
I'm with Perry Rose. Start some ads and get learning. It would take a 3 hour glass to explain from the beginning

Once you get to know how to use ppc for traffic, the next important thing is how to optimize ppc campaigns for optimal results and saving money, by tracking which keywords make people buy and which landing pages convert best.
Be very careful when starting out. Try and start out with a small budget of a few months. Don't put real money in until you understand it fully.
ppc could be very expensive unless you do it right. target some keywords, make some ads for those targeted keywords. You should have a relevant landing page as well.
