As of March 1st, Google implements its new, unified privacy policy, which will affect data Google collected on you prior to March 1st as well as data it collects on you in the future. This data will be pooled along with any data from Youtube in an attempt to build a more accurate profile on you, so that they can try to target-sell to you, or recommend to you whatever they think you might be interested in… at least, that’s what Google says it’s for…
So, if you wish to stay anonymous on-line, you may be interested in deleting your Google Web History as well as your Youtube Viewing and Search History. Some are taking it a step further, boycotting the use of any Google products as Google was already seen as a credible threat to privacy long before this most recent step in the wrong direction.
Here are a couple of guides, with further info on steps you should take.
