PPC Search Arbitrage Come Back?

If you didn't know what's PPC Search Arbitrage, you could read Jake Baillie's post in 2006, in which you could even find out the history of PPC search arbitrage. In short PPC arbitrage means sending mass traffic in low price to your landing page placing AD from other advertiser with higher CTR, your profit comes from the  margin between outgoing ppc * revshare * CTR and source PPC.
Maybe you notice it's so profitable as for you can easy expand your input and get more revenue. But the most important is how to find the difference between different advertisers and the second are insuring the CTR of your landing page.
Some internet magnate, including Yahoo Shopping, CNet, Shopping.com, Verizon, Info.com, PriceGrabber, NextTag, eBay, etc. take part in PPC search arbitrage too. Off course that they have blotted out in their real business model.
But PPC search arbitrage infract Google's policy and profit, so Google forbid similar operation in 2006 and in this year many AdWords accounts were banned. For someone, PPC arbitrage is died in 2006.
Is it true?
Just after two years, Danny Sullivan find Ask.com Plays The Google AdWords Arbitrage Game in 2008, so PPC arbitrage still alive and Google just say no to smaller business owner.
Ask.com is not the only example, Info.com begin to follow it, let's review below Info.com's landing page.

How about? It's unassailable MFA site.
But I don't suggest you follow those operation, if you have ability that finding keyword with low cost and high conversion rate, why not try CPA? it's more profitable and safe.

Turn to Email Marketing

I will begin a Email marketing test in the next days after planing long time.

Always I have a misunderstanding that Email is needless capital in Web2.0, this opinion comes from habit of mostly of Chinese on internet. Although I need to check my two or three Email inbox several times daily, but I think it's requirement of business and mostly common people shouldn't log their Email one time in the whole month. I'm right for it's real in China and wrong because it is not fit for Occidental.

John Chow thought his biggest mistake while marketing is that he didn't build a Email list in the begin of blogging, after discovering the secret of list, he begin to build huge list immediately like other super affiliate marketer.

Perhaps people would not pay more time in sending or receiving Email, but their email address would be their username in Facebook. and they still need receive some notice from their service such as Paypal etc. after using so long time, Email address even become a special identity symbol in internet.

I'm wrong and underrate the effect of Email Marketing, it's time to put right. So I would begin a test to understand the real of Email Marketing.
