How Google Might Generate Search Results Snippets

Search Results Snippets

When you perform a search at Google, and you have a set of search results in front of you, how do you decide which result to click upon? How do you judge the page titles, snippets, and URLs that you see? How does Google decide what to show you?

A little more than a year ago, Google Webmaster Trends Analyst Pierre Far wrote on the Google Webmaster Central Blog a post titled Better page titles in search results. There he told us that Google might sometimes rewrite titles for web pages when showing them in search result snippets. The post also told us that Google might do some changing of titles when those had generic titles such as “home”, or no title at all, or:

We use many signals to decide which title to show to users, primarily the <title> tag if the webmaster specified one. But for some pages, a single title might not be the best one to show for all queries, and so we have algorithms that generate alternative titles to make it easier for our users to recognize relevant pages.

Before we consider how Google might decide when and how to change page titles (in a follow-up post to this one), there’s another question about search results snippets that needs some exploration. Google often decides upon the search snippets that it might show based upon the query terms that a page is being found for.

Google News Algorithm Updated

The image above, from Google’s patent shows a source rank that no longer exists in the same way that it did when this patent was first published. Algorithms can change over time, and this one likely did.

Neither The Nation or Computerworld should write about patents. Period. Never. In the past couple of days Computerworld posted a “breaking news” story about the publication of a Google patent application from 9 months ago (not breaking news). The Nation wrote a followup story on Computerworld‘s story, and made the same mistake.

Both saw optimism when they should have instead felt fear.

They weren’t publishing information about a 9-month-old patent, but rather a ten-year-old patent. They would have known that if they ever wrote about patents. 🙂

Inside the Google House of Ideas: 2 Lens Glass, Google Robots, and Smartwatches

There are rumors that Google will be opening retail stores sometime in the near future (some rumors point to next year). The question rises though, what will Google feature in those storefronts? Will Chromebooks be a kiosk filler item? Will we see Android based phones? Are Google Glass wearable eye glasses still somewhat far off? Might self-driving cars still face changes in state legislation? Google TV might be a possibility. Home entertainment systems running on Android Hardware could also be shelf stuffers. Or will Google pull out some surprises for us?

Some recent patent filings from Google provide some possible hints at what we might see in Googleshops (or whatever they might be called) at some point, if Google does indeed open retail shops.

A look at how 2 lens glasses might be calibrated from the patent.

Google Lifestreaming?

Imagine recording your life, so that you can search through it, and play it back later. Things that you record through audio and video might be sent to your own personal search database where pictures you take might be processed. Images of faces may go through facial recognition software. Landmarks and objects might also be recognized as well. You might be able to write or speak queries like the following:

  • What was the playlist of songs at the party last night?
  • What were the paintings I saw when I was on vacation in Paris
  • Who were the people at the business lunch this afternoon?
  • How many books did I read in May?

It’s possible that you might be able to collect information like this, and have it associated with both your user ID and a digital signature to keep it from others, unless you decided to join with a group such as a family, or firefighters, or co-workers, to create a shared database for one or more events.

Google Patents Identifying User Location Spam

Google collects information about where you compute from and provides location-based services based upon where you travel. To protect this information, and to use it to protect people from spam and scrapers, Google might follow processes to protect that information and to analyze it, to find user location spam.

Post a review from Germany about a restaurant, and then 15 minutes later from Hawaii about another restaurant, it’s user location spam. Drive down a highway where the cell towers collecting information about your journey are located in the middle of Lake Michigan, it’s likely user location spam. If GPS says you’re in NYC, and you then connect via Wifi in Wisconsin a few minutes later, user location spam. This information may not even come from you, but rather from others that might impersonate you.

Google was granted a patent last week which explores how they could use location-based data to identify spammers and scrapers. It would also put user location information in quarantine, and possibly hide starting and/or ending points for journeys from mobile devices to protect privacy for users, and to explore whether or not the information is spam. The location information could be used by the search engine, and that detailed information about locations to keep some information from being used in location-based services, or other services that Google might offer.

Google Patent Granted on Mobile Location Detection

Google has a lot invested in knowing where you are. The future of search, and many of the services that Google offers is going to rely upon it being accurate, too. It can’t be off by 30 meters, like it might be with cell tower triangulation. It can’t rely upon a GPS system initially built for aircraft with multiple antennas. It needs to be able to work indoors as well as outdoors. Unlike the electronic navigation device below, it also needs to be really small. How will Google do Mobile Location Detection?

The purpose behind a Global Positioning System, or GPS, is a satellite-based navigation system helping to overcome problems with previous navigation systems. We know that Google has used GPS in mobile devices to make it possible for a number of location-based services to function.
