Hi. Please excuse me if my questions have been covered in another post. If so please direct me to the related post - I have been looking for awhile and have not found anything.
I have been looking at the technologies table which contains some very interesting/useful data. However, I have two very specific questions.
Can a site’s framework info be trusted? The reason I ask this is because I have seen some posts that discuss the difficulties/challenges in determining the framework a given site uses. My interest lies in wanting to see if the is a correlation between framework and performance over time. Perhaps there is a better way…?
I pulled data from technologies table over time and something struck me immediately - there are some sites that do not have any entires. For example I am curious about amazon.com and cannot find any data recorded for Amazon. So I have two related questions. The first is why would a particular site be missing? The second is can a site “opt out” or prevent this data from being collected?
All input is much appreciated. Thank you.
