Relevance & Quality Score

 I am amazed at all the ways we have a analyzing, quantifying, and qualifying so many different types of data.  It does not seem that long ago that we had to fill out paper surveys to get even a fraction of the information that seems to be so readily available.  That same information can be used to adjust and modify responses, key words, and ads.  It is still a little confusing to me what each data point represents but I have a pretty clear understanding of the overall concepts.  I figure it will all become more clear as I start to manipulate my own data.  I hope that the concepts I have are close enough to the actual facts of how it works that it won't take me too long to catch on.  I guess we will see.
