In a move that is sure to please pro privacy advocates while simultaneously upsetting many marketing managers and SEO consultants, Google has officially killed referred data for users who conduct a search query while logged into a Google service. Anyone not signed in though will continue to send referrer data.
What does this mean to marketers and SEOs? Well for starters, you’ll no longer see the keyword referrals that triggered the organic visit in your analytics, even if you use Google Analytics. While you will still know the visits came from a free or organic search you’ll no longer be able to see the keyword phrase associated with the visit as it won’t be passed along. This of course will make it much more difficult to understand what keywords from organic search are paying the bills.
It’s important to note that this change does not impact paid search (also know as PPC). Google will still pass all of the keyword referrer data regardless of whether the user is behind a secure connection in order to ensure that advertisers are able to track what’s working.
With so much of Google’s revenue driven by paid search, it’s no surprise they’d keep the data flowing for advertisers. Despite the discrepancy, I can’t really blame them. I know I’d be quite upset, if I was told I could no longer see how my ads were performing. While “Trust me” might be okay in traditional media land, it just doesn’t cut it in the online advertising world.
While advertisers will continue to have access to the data, those marketers who have built their businesses purely on SEO will find it more difficult to do so in the future. @MattCutts suggests the change will only affect a small number of users to start (in the single digits) but I imagine the percentage of encrypted searches will likely grow over time as encrypted search becomes more common and eventually the default for all search queries. Good or bad, the days of building a business purely off the back of SEO may be over.
Ultimately, this could mean more advertisers for Google as website owners and markets, especially for new sites will need to run some form of campaign to see exactly what works before investing in SEO. While marketers will still be able to build an optimised website out of the gate, it will become a lot more difficult to prove to the skeptics that SEO is a viable and profitable channel.
As a consumer, I support the move, especially knowing how much information is left behind from our daily activities. But as a marketer I’m left just a little frustrated that I’ll have to start relying a lot more on saying “Trust me, it works.”

What do you think? Do you believe this will kill SEO or just make it more challenging and drive more businesses to work with professionals?
