This happens all the time. I have had consultations with clients who had been given proposals by other SEO’s to create pages just for search engines and other blackhat techniques. Sometimes these techniques go un-noticed and work for a while, but eventually, they get found out. It’s good to see Google is trying to clean up its index and make an example of a large company like BMW.
One thing is for sure… I wouldn’t want to be the SEO who worked on this site 😉
