I just read an article regarding SEO vs. Pay Per Click on an internet forum. The article summed up what it means to appear # 1 through #6 in Google's natural search perfectly. The quote was "Having the first spot or even the 5th or 6th in Google for your keywords is like having a huge billboard in the middle of Times Square." Think about that for a minute. Let that sink in. Got it? Good. Let's continue. The article goes on to say "That kind of traffic is intense and the exposure is priceless! We can say the same about a great ranking on a PPC campaign, but remember one thing - you will always have to pay for it. Free clicks in sponsored search? Never."
