Navigation – A list of pages on a web site that reveals different content on different pages appears in a row along the top or on the left side of the pages; these may be expressed by names of pages such as Introduction, About Us, Corporate Overview, Contact Us and others or denoted by icons or symbols. These navigation tools help the user to visit different sections of the website.
Negative Keyword – Just as Google AdWords is based on keyword matching or correlating similar words, so too there is the concept of Negative Keyword that refers to words that the user does not want their ad to be linked to. This tool ensures focused keyword matching to obtain serious traffic and not simply by volumes without relevance.
Negative SEO – This refers to the act of bringing a page lower down in the list from the Search Engine Results Page.
Noframes tag – If your web page is limited by frames and thereby do not lend themselves to search engine activity, it is a good idea to rebuild the site with noframes pages. Alternatively, insert keyword-rich text in noframes tags; it will still remain search engine unfriendly, however.
