The Google Hummingbird Patent?

Google introduced a new algorithm by the name of Hummingbird to the world today at the garage where Google started as a business, during a celebration of Google’s 15th Birthday. Google doesn’t appear to have replaced previous signals such as PageRank or many of the other signals that they use to rank pages. The announcement of the new algorithm told us that Google actually started using Hummingbird a number of weeks ago, and that it potentially impacts around 90% of all searches.

It’s being presented as a query expansion or broadening approach which can better understand longer natural language queries, like the ones that people might speak instead of shorter keyword matching queries which someone might type into a search box.

How Google May Reform Queries Based on Co-Occurrence in Query Sessions

When you search, especially for topics that you know little about, chances are that you might not include the most relevant terms in your query, or you might use words that may have ambiguous meanings.

One of the areas where search engines focus a lot of attention upon is in reformulating queries through query suggestions and query expansion to help searchers better meet their situational and informational needs quickly.

"Google query suggestions on a search for [find airedale terrier puppies]"

When you search, you might see a number of query suggestions at the bottom of the results that were first returned, like the ones above on a search for [find airedale terrier puppies]. Or a search engine might include synonyms or substitute queries to expand your original query.

Relationships between Search Entities

When I talk about, or write about entities, it’s normally in the context of specific people, places, or things. Google was granted a patent recently which discusses a different type of entity, in a more narrow manner. These entities are referred to as “search entities”, and the patent uses them to predict probabilities and understand the relationship between them better. This kind of analysis might result in some pages ranking higher than they otherwise might because of their similarities to other sites, and in some sets of search results favoring fresher results as well.

How Google May Substitute Query Terms with Co-Occurrence

But I’m a substitute for another guy
I look pretty tall but my heels are high
The simple things you see are all complicated
I look pretty young, but I’m just backdated, yeah

- Peter Townsend

When you search at Google, how easy is it to find what you’re looking for? Do you search again, but try different but related words if your first attempt doesn’t uncover pages that you find useful?

If I search for “car repair” and follow it up on a search for “auto repair,” I would suspect that I would see a lot of the same pages, but perhaps not in the same order. I would also expect to see local search results for both, and I do. The local search results aren’t in the exact same order either. Some words or phrases do make good substitutes for others though, as can be seen in the image below:

Google Patents Anchor Text Snippets

Somewhere out there is a universe that looks exactly like this one, and appears to run exactly like this one. Except something’s a little different. A little off. It’s as if search engines took a left turn instead of a right turn, back in the early 2000s. Instead of using only using meta descriptions and possibly body text from web pages for descriptive text, or snippets, for those pages in search results, they learned a new trick. Imagine that the content surrounding anchor text in a link to a page was collected and evaluated based upon a quality score, and that this associated and usually descriptive text was used to generate snippets instead?

My thought on the possibility is that often anchor text doesn’t do the best job of describing a page, and often links to a page are from a third party who might not have the same interest in writing text that might make a good snippet for a page. But, Google filed a patent for such an approach back in 2003. And it was granted this week – so they pursued what was described within the patent for over a decade as well. The patent does mention that headings on pages might also be used as potential snippets for pages, and provide the following example: “Computers > Algorithms > Compression”. But that’s a small part of the patent. They don’t limit it to anchor text that a site might provide itself, like in breadcrumb trail navigation for a page.

There’s also a part to this approach that recognizes that many pages have more than one link to them, so a choice would need to be made as to the best “snippet” to show.

How Google May Classify Pages Using Hierarchical Categories in URLs

Google was granted an updated version of a patent this week that looks at how the search engine might use directories in URL structures to help it better understand the categories on a Web site, and to categorize new pages and directories that might be added to a site. The patent tells us that this might enable the search engine to add supplemental information to pages, such as advertisements that fall within the categories displayed upon the site.

Some other patents I’ve written about in the past shows that the search engines might be doing more with categories than just deciding upon which ads to show on a page

Imagine that you have a site about car parts, and you decided to organize the pages of the site first by car make, so the main categories on your site are different brands, and your second level of directories is organized by car models. You might then have sub-sub-categories that are organized by different systems within cars, such as “electrical,” “transmission,” “cooling,” “suspension,” and so on. URLs for a couple of your pages might look like:

Google Patents on Author Signature Values and Authority Scores

Last week, Google was granted a number of patents exploring different aspects of how documents on the Web might be ranked in part based upon topics identified for those documents and the expertise and/or authority of authors involved in the creation of the documents. The process also describes how Google might use different methods to determine the authority of multiple authors who may have worked to create the documents.

This sounds very similar to some statements that Google’s Matt Cutts made at the start of May in a video about What should we expect in the next few months in terms of SEO for Google?

George Bush is a Miserable Failure Again, in Google’s Knowledge Base

I’ve written about Google Bombs in the past, and how a bio page featuring President George Bush ranked highly on a search for “Miserable Failure” as a result of a Google Bomb, in a post from 2011 titled How a Search Engine Might Fight Googlebombing.

In a post from earlier today, Nemek Nowaczyk wrote a post Google Bombing the Knowledge Graph: Who’s a Liar? He noticed that on a search for “liar” (in Polish), Poland’s Prime Minister Donald Tusk appears in the knowledge base results for the search. Nemek sent me an email with a link to his post. Within seconds, I was typing one of the better known English language Google bomb phrases into a Google search, with a guess as to what I would see there.

Ok, so the top knowledge base result on a search for “miserable failure” wasn’t George Bush. But a smiling George Bush was close enough to be a “see results about” disambiguation knowledge panel result.
