What does Keyword Stuffing means?
"Keyword stuffing" refers to the practice of loading a webpage with keywords or numbers in an attempt to manipulate a site's ranking in Google search results.
Sorry, but this is far too vague a question, and as you can see from the answers you've received, a simple search would have sufficed to answer the question. Please search (both the forums and via your favorite search engine), and if you've still got SPECIFIC questions, please feel free to repost.
In the meantime, THREAD CLOSED.
