Google’s Personalized Search Revolution
The revolution will be liveblogged. Bryan Horling, a software engineer for Google Personalized Search, is in the house, as is the man, Danny Sullivan. Danny says that personalized search was a revolution because it happened whether people were logged in or not. It changed search at a fundamental level. That scared some SEOs who didn’t know how their clients were ranking.
Bryan’s the only speaker at this session because he’s the only one who volunteers to speak on the topic. To some degree there isn’t a whole lot that can be done to influence them as a marketer — other than have really good content. A lot of people can’t get their head around it. Hopefully this session helps.
What should Google show for the query [SMX]? Most in the room would agree it’s searchmarketingexpo.com. But SMX means different things depending on the location. In the UK, SMX is a motorcross club. In Santa Maria, CA, SMX is the airport code.
Or if a user’s previous search was [xb], the result Honda.co.jp/s-mx, a similar car, might show up.
Search queries are frequently imprecise. Personalization can help fill in the gaps:
This must be done in a privacy-sensitive way:
- Transparency: notice of how and where info is being used
- Control: give users ways to manage their info
A search for [taxes] will bring up different results for the UK than the US, based on the organization in charge of taxes in the country.
A search for [bus schedule] will focus on the city a searcher is in, such as the MBTA for Boston, but it will also include results that are broader, like Greyhound, that services more than one area.
More Search Details
When results are personalized for a logged-in user, they can customize the search preferences. You can change your location when a location specific result is served. This can also be specified in Google Maps.
Search Nearby Tool
There are additional search options for search today. You can specify results nearby as well as a custom location.
Signed-In Web History
In the top right corner of search results, signed-in users will see a link to Web History. From the Web History page, a user can remove or pause items on the list, or wipe out the entire history. Data is retained forever, or until removed.
Signed-Out Personalized Search
Non-signed in users, tracked by browser cookies, will see personalization of search results. Under the hood it works a lot the same way as a signed-in user. However, a user can’t manage their Web history and can’t see the items being used. A user can turn the signed-out Web history on or off. Data is retained for 180 days.
Long-Term History Disambiguation
For most people, the search [vector] is for vector graphics or to find a company named Vector. But for programmers with a long-term history of programming related searches, the query [vector] is a navigational query to a C++ resource.
The Web History Tool exposes information about Web history. For instance, you can see only visited pages or not-yet-visited pages.
These results surface content from your social circle. This is another way search results are being personalized for the individual. The intuition behind this is that if you were to see two results on the same topic by someone you know and someone you don’t know, the result from someone you know may have more meaning in the context of knowing the author. Results served in social search will have a link to your social circle as well as your social content. You can search from a single social contact.
