Welcome to the Q&A Forum

I have a web site that is over 10 yrs old, It  also has over 30,000 links to it.  Last week it received a N/A or "grey bar" page rank.  The site also still is listed in the SERPS for my keywords, in fact for a few they have actually improved.  The organic traffic is following the same pattern as last year. Webmaster tools doesnt list any critical issues or errors. Is there anything I can do to remedy the situation, or is this just a wait and see? Website is www.netnanny.com.

I would like to find all of the keywords not just the keywords that I specified in the tracking section.

I have several pages on my domain that are using the same content except for changing a paragraph or sentence. Do I need to create unique content, even though much of the information pertains to a feature and is related?
