AnsDMOZ listings, Title tags, Meta Description tags and text culled from the body of the page

Google has recently been identified as using text culled from the page, the meta-description created by the page author, or the DMOZ description when displaying results in their listings.

2. What is typically regarded as the "optimal" keyword density?
Ans.No optimal kw density exists because search engines do not use it for ranking purposes

Keyword density is used by the search engines only to determine which documents might be relevant to a particular query. Term weight is what the search engines use to determine the strength of a term/phrase in a particular document for ranking purposes.

3. Which of the following file types are NOT cached by Google?
Ans.Macromedia Flash files (.fla)

Google claims to be able to spider and cache all of the documents above with the exception of Macromedia Flash designer files (.fla) and nonsense files. However, tests by several SEOs, including, most recently, one that was posted about by Mikkel deMib Svensen at SEW reveals that Google can spider and create "cached snapshots" of any html/xml compatible file no matter its extension.

4. How many characters (including spaces) of a web page's title tag does Yahoo! display on the results page?
Ans.More than 80 characters

Yahoo! will show up to 119 characters (including spaces) in the title of a search result listing.

5. When designing the information architecture of a website, which of the following statements is NOT a good idea
Ans.Reduce external links to as few as possible to avoid leaking PageRank out of the site

Reducing external links to avoid leaking PageRank is an unwise decision as search engines, including Google do not penalize for "leaked" link popularity and often reward pages and sites with on-topic relevant outbound links.

6. Which tag is preferred by the W3C for emphasizing important text?Ans. < strong >


The W3C notes that the < strong > tag is the preferred method of emphasizing text, rather than simply changing its visual effect.

7. What percentage of a page's contents must be the same for a search engine to consider it "duplicate content"?
Ans.No set percentage, the value change constantly and have never been disclosed

The percentage of similiar or replicated content required to trigger a "duplicate content" penalty varies among the search engines and is thought to be dynamic so that no testing can reveal the exact percentage.
