I had written an article related to Google's SERP based on a certain thing. In the process I invented a term for which my article should rank quite good, the term had not been used anywhere else (as far as I know, confirmed with Google). I confirmed my assumption, it did indeed rank quite good - quite near the top spot, 1st page.
Today it's gone from Google's index. Confirmed it with the :site parameter.
Strange observation, what could have caused that? My blog is nothing spammy or suspicious in nature. All original content. The content is less as of now, I update it once in a while, it's a year old blog. Some of my posts rank quite good, they are still in their places, except for the one related to SERP. Is Google trying to shut me up or am I just paranoid?
