I had a page that was ranking 27 in Google for the keyword which has about 6 million listings. I decided to do on page SEO for that kw and change the page name to include the KW. This was last Thursday. I had a little bit of off page SEO done also but only 2 backlinks are showing to the page on Yahoo. Yesterday Google still had the old page, but it had been slipping 1 rank a day. Today, the new page/kw combo debuts at #6. I assume this is typical and I can expect rapid decent? I know I need to build backlinks. But, is there anything to learn from this or is this just standard?
