Google wants you to complain if you are dissatisfied with the search results. This means we can complain our site is not on the first spot right?

Comments Please

Google will never listen to what we complain about

I don't think they will read all the comments...

I tried complaining especially when you search and find so many MFA pages, but I doubt anyone bothered to read at all.

I think they will listen if your complain is that you can't find what you want using the result or you're not satisfied with the result.

Definitely Google wouldn't read all those comments.. I think if they do, they will spend everyday just reading them..

Instead u can use spam reporting through webmaster tool
