: Is Google "Not Provided" only affect non-SSL website? Based on this blog post, Google Analytics may not be providing keyword referral data anymore Google not provide their search keyword

@Jessie594

It's not quite a case of Google choosing to replace the keyword with Not Provided. The issue here is that Google runs all of Google search using HTTPS. A safety restriction built into all browsers is not to provide the referrer header when the referrer is a HTTPS site, this is an intentional security feature. The way most libraries have worked in the past to get the keywords used for the Google search that brought the user to the site in question was to get the data out of the referrer header which had the Google SERP URL that the user came from and which contained the search string and keywords. As this is no longer happening due to the HTTPS restriction there is no data provided hence the Not Provided result if you try to get the referrer keyword.
