My website has always ranked in the top 5 for a particular keyword. It has quality content, design, and is updated frequently. One dreadful late September morning I wake up to a Google search results page that is completely different than what I have previously remembered. New sites I have seen in the 2nd/3rd pages mysteriously moved up to the first page. My site was completely removed from the search results. It's nowhere to be found. The website is not flagged as I rank for other keywords, but for this one MAJOR keyword, I am no where there. Does anyone know a solution for me? I really need to increase my ranking back to where it was. Any advice is greatly appreciated.
