Can be doing sites just for SEO considered BLACKHAT?
 

I was now examine description of blackhat and notice doing sites just for SEO could lead banning domain from search engine.What is best way to avoid banning?Can combination of white and black seo can prevent banning?But there is also in description each SEO can be consider as blackhat SEO.So now i dont know what i can do and what not.

have original content and whitehat links acquisitions and no way you are black hat :P

most search engines will describe any effort to gain rankings "black hat"

I just realize redirection human visitor to one content and bot to another is consider clocking,which is blackhat.Must update site fast :)
What about off site spamming?If i add domain name after end of this comment,can be that considered as spamming since domain name is not related at all with comment?
