On October 18th 2011, Google announced they would be encrypting search queries, for privacy reasons. Unfortunately, this disrupted organic keyword referral data, returning “(not provided)” for some organic traffic. This number increased in the weeks following the launch.
Most users used non-SSL Google for their searches. Now, according to Google, “…a web site accessed through organic search results on http://www.google.com (non-SSL) can see both that the user came from google.com and their search query… However, for organic search results on SSL search, a web site will only know that the user came from google.com.” The effects were obvious immediately.
In this emergency Whiteboard Friday provided on seomoz.com, Rand will go over the changes Google has made, why it happened (and why it really might have happened), and what you can do to stay calm and fight back.
Google’s statements on the topic are:
We’ve worked hard over the past few years to increase our services’ use of an encryption protocol called SSL, as well as encouraging the industry to adopt stronger security standards. For example, we made SSL the default setting in Gmail in January 2010 and introduced an encrypted search service located at https://encrypted.google.com four months later. Other prominent web companies have also added SSL support in recent months.
As search becomes an increasingly customized experience, we recognize the growing importance of protecting the personalized search results we deliver. As a result, we’re enhancing our default search experience for signed-in users. Over the next few weeks, many of you will find yourselves redirected to https://www.google.com (note the extra “s”) when you’re signed in to your Google Account. This change encrypts your search queries and Google’s results page. This is especially important when you’re using an unsecured Internet connection, such as a WiFi hotspot in an Internet cafe. You can also navigate to https://www.google.com directly if you’re signed out or if you don’t have a Google Account.
What does this mean for sites that receive clicks from Google search results? When you search from https://www.google.com, websites you visit from our organic search listings will still know that you came from Google, but won’t receive information about each individual query. They can also receive an aggregated list of the top 1,000 search queries that drove traffic to their site for each of the past 30 days through Google Webmaster Tools. This information helps webmasters keep more accurate statistics about their user traffic. If you choose to click on an ad appearing on our search results page, your browser will continue to send the relevant query over the network to enable advertisers to measure the effectiveness of their campaigns and to improve the ads and offers they present to you.
