Keyword Density:
1) Amount of times that a keyword phrase is used on a page.
2) A formula to determine whether keywords are being overused on a page.  The formula is the total number of words in al keyword mentions divided by the total number of words on a page.  Keywords should fall between 2 and 8 % density.
Landing Page:

Link Popularity:
The number and quality of links on other sites pointed to a Web page.  Search engines increasingly rely on this to determine their rankings.  Also called Page Relevance or page score.
Multiple copies of web sites or web pages, often on different servers using different domain names. The process of registering these multiple copies with search engines is often treated as spamdexing, because it artificially increases the relevancy of the pages.  This spamming technique can be detected by the search engines and the site can be penalized for it by a lower ranking or removal from the database.
As defined by Google “PageRank relies on the uniquely democratic nature of the web by using its vast link structure as an indicator of an individual page’s value. In essence, Google interprets a link from page A to page B as a vote, by page A, for page B. But, Google looks at more than the sheer volume of votes, or links a page receives; it also analyzes the page that casts the vote. Votes cast by pages that are themselves “important” weigh more heavily and help to make other pages “important.”  Note: This is a depreciated term.

Paid Placement:
