Question about weighing down keywords and phrases
 

May sound like a strange question, but when weighing down keywords, does it matter if using bold tags or strong tags?
And if doing it to a keyphrase, like "Free teen video", would it be of any benefit to wrap each word individually in tags???

H1 is your friend.

Well in my blog situation, the header tags are used on other aspects, and would fuck up text size inside the article. see http://UncleInky.com

Would it be best then to define a heavier <h4> or something? And if so any specific values that help the process?
