There is nothing new to Google Suggest being controversial with their suggestions. But when Google Suggest became the default on Google.com about a year ago, the suggestions became more prominent.
The business of online reputation management has been growing with Google's dominance. Normally, you don't see reputation management issues about individuals within the Google Suggest area. However, I spotted a Google Web Search Help thread with one person who said that if you type his name in Google, it suggests [scammer] at the end.
This individual is embarrassed and wants that suggestion removed from Google. He asked how can that be done. The quick answer is that it cannot be removed. Googler, Jem, said:
Suggestions in Google Suggest are based on actual queries done by other Google users. At Google, we believe strongly in the democracy of the Web, so we don't make manual changes to the suggestions. But that doesn't mean the suggestions are set in stone. Changes in the popularity of a search can affect whether it continues to appear over time.
In short, if people stop searching for his name with scammer at the end, then it might not show up in the future.
Can a reputation management company help with that? Possibly.
