Although I don't really have evidence for this, it seems to me that the phrase "go ahead and head on over to [...]" prevails more and more over simply "go to [...]". This phenomenon is particularly noticeable on the Internet; not only in articles, blogs, etc. but also in videos and podcasts. The phrase returns close to 1.8 million hits on Google at the time of writing this question.
Example:
Go ahead and head on over to my website, for more details.
Am I right in thinking that "Go ahead and head on over to..." is becoming more and more common?
Is some nuance of "Go ahead and head on over to" lost on me?
