I have been reading up on SEO a good bit more, including purchasing a couple more recent 'making money online' and joint venture books. (I have really only read one so far that was a complete waste of time, most have been great.) Anywho, in the one book I am currently on, the fellow defines the difference between white hat and black hat SEO marketing. One of the examples he gives is inflating your page with back links that are not legitimate to increase a websites pagerank is a blackhat technique, and if your website gets pulled or deindexed, you're in trouble. He says using white hat SEO takes longer, but allows you to rank up naturally and has better yielding results in the long term for making a profitable website online. (Makes Sense) However, I know a lot of websites/marketing teams that use a mix of white grey and black hat techniques, and have researched the pages links as well, and I have yet to find a substantiated website that is for one reason or another "deindexed" or not searchable in google in some way. Is what he is saying about this hooha? Or does it have some merit to it. Personal experiences are great, btw!!
