If I use long tail keyword such as "blackhat website marketing online" would it only give me a boost for "blackhat website marketing online" or would it give me a boost for all keywords in the phrase such as "blackhat website", "marketing online", "Blackhat Marketing", "website marketing", etc...I know this is what you should practice when using on page SEO, but what about inbound anchor text? And does it also depend on the landing page optimization weather it's longtail or shorttail?
