Placement of keywords

First, the title page should repeat title the article and your passphrase (for details on how to write headlines for the articles).
Second, eat a key uniformly, for example every 500 characters of text (but not often).
Third, the key phrase should be at the beginning of the text in the first 250 characters, but it is better to put him in the first 150.
Fourth, use these keys to refer to this page, even from the same site (for internal references), but what is better with someone else (external link).
And fifthly, use the keywords you invented when you write "tag site."
