    I am working as a freelance SEO I got this client that got slap heavily by an update of algo. I did a little investigation then found out that the links were all good, high TF and CF, and good anchor text ratio. On-page got no more errors except missing alt tag in images.

    The only problem I found was the hundreds of inner pages that are from Russian and Indian language that have been an index in Google.

    I never experienced this like this, and I think this website was targeted one of the automated tools such as GSA, Scrapebox or other tools.

    How do tell Google to de-index those? By robot.txt?
