My First action is to block the said post by my robot.txt so that next time that Google will crawl my blog it will not crawl the said post. I don’t know if this will work. Some of my optimized keywords is not being seen in the post. So I where you try to blog Google BOT on your Optimized blogs post regarding the recent event. I hope this work.
This is just an information and I will tell you any changes that might happen in the future.
Anybody experienced the same thing ?
