Google makes personalised search more secure

During October Google announced that it is going to increase the privacy for users of their search engine by encrypting personalised search results. This has caused much consternation in the search engine marketing field, since the end result will be that search query data will no longer be accessible through any web analytics stats from these searchers.

Google says that this change is important for security and privacy, so that users who sign into their Google account will get their search queries encrypted by default. As the use of the search engine is becoming an increasingly customised experience, the results become tailored towards individual users.

This additional layer of security means that Google and the web browser itself can only see any searches. A third party can’t intercept the search and know what’s being searched on, so it’s especially important for people that search using an unsecured Internet connection, such as a WiFi hotspot in an Internet cafe.

Google is doing this by securing the results for signed-in users, through the use of an encryption protocol called SSL (Secure Sockets Layer). This is the same technology that is used when performing secure credit card transactions and is evident by the extra “s” in the “https” in the address bar for Google’s homepage, when signed in to a user account.

Google may hope that this change will encourage more people to search through a personalised account, which will protect the user’s information but also allow Google to display more relevant results to the user. However, the downside for website owners and marketers is that less information will be available in Google Analytics – or any analytics package – so that although visits from Google’s organic results will still be counted, the individual search terms from logged-in users will be hidden and just displayed as ‘not provided’.

Google says that an aggregated list of the top 1,000 search queries that drove traffic to a site for each of the past 30 days will be available through Google Webmaster Tools and also any AdWords data will still be displayed at the search term level, whether the searcher is logged in to a Google account or not. However, the loss of organic search term data is significant and will become more so over time.

Initially this change will only happen on Google.com, and only relates to those searchers who are logged into a Google account. According to Google’s software engineer Matt Cutts, this is likely to account for only single-digit percentages of all Google searchers on Google.com at this time. However, as more people use Google’s services such as Gmail or Google+ and remain logged in when they search, this percentage is likely to grow and impact the level of data available through web analytics accounts.

We’ll be tracking this issue and reviewing the impact over the coming months, but if you’d like to know more about this and how the change may affect your search referral data in analytics, please contact us now.
