I was really disappointed having my website penalized in Google search results. Each of the page got penalized one at a time. For the very first instance, my ranking was gone. I came to know that unindexed pages when I built the website domain search. I could not even locate this on Google. Currently, my ranking for other keywords that I used is lost. But, a number of pages still appear in Google. How did this happen? I do not really understand the logic behind this. I do not even practice black hat SEO and link building in my website.
