Google Penalty for One Blog Post? - It Can Happen!

I think I was hit by a Google penalty. I didn't receive any notification on my Search console, though. But suddenly I wasn't ranking well for my most popular post. Since that post brings most of my traffic, my daily traffic suddenly dropped from around 200 to around 60.

The day my traffic dropped was when I publish a post Google may not have liked. At least I couldn't figure out any other reason why the traffic dropped then.

The post may not have been so great, maybe I used the keyword phrase too much and there were too many similarities to posts I had already published before.

Whatever it was, that post didn't please Google, so I suppose Google punished me for one blog post. This proves just one blog post can get you in trouble!

Since that blog post seemed to only bring trouble to me, I removed the whole post. I wonder if it's a coincidence that after removing the post, another post I had published after the problematic post had ranked on first page, position 1 on Google. And Google hadn't ranked it before now, even though all other search results for that keyword were crappy and low quality.

So, be careful with ALL content you publish on your site; even one blog post can get you in trouble if you don't please Google.
