An example of what happens when Google releases an algorithm update. Specifically the Hummingbird update of April 2015. This gives an example of the kind of questions asked, with their answers. It is given as an example of how an update can effect your search results.
What Is Google Hummingbird?
On April 21, 2015, Google released a significant new mobile-friendly ranking algorithm, they called Hummingbird, that’s designed to give a boost to mobile-friendly pages in Google’s mobile search results.
What this means is that Google from this date is looking for websites to be mobile friendly, in other words responsive, if you site isn’t, it needs to be or it will not make the search rankings.
The name “Hummingbird” was chosen because Google is expecting a website to be “precise and fast” and is designed to better focus on the meaning behind the words used on the webpage.
“Hummingbird” pays more attention to each word in a query, ensuring that the whole query — the whole sentence or conversation or meaning — is taken into account, rather than particular words. The goal is that pages matching the meaning do better, rather than pages matching just a few words.
So that “PageRank” algorithm is dead?
No. PageRank is one of over 200 major “ingredients” that go into the Hummingbird recipe. Hummingbird looks at PageRank — how important links to a page are deemed to be — along with other factors like whether Google believes a page is of good quality, the words used on it and many other things (see our Periodic Table Of SEO Success Factors for a better sense of some of these).
What does it mean that Hummingbird is now being used?
Think of a car built in the 1950s. It might have a great engine, but it might also be an engine that lacks things like fuel injection or be unable to use unleaded fuel. When Google switched to Hummingbird, it’s as if it dropped the old engine out of a car and put in a new one. It also did this so quickly that no one really noticed the switch.
The new engine is using old parts?
Yes. And no. Some of the parts are perfectly good, so there was no reason to toss them out. Other parts are constantly being replaced. In general, Hummingbird — Google says — is a new engine built on both existing and new parts, organized in a way to especially serve the search demands of today, rather than one created for the needs of ten years ago, with the technologies back then.
What type of “new” search activity does Hummingbird help?
“Conversational search” is one of the biggest examples Google gave. People, when speaking searches, may find it more useful to have a conversation.
“What’s the closest place to buy the iPhone 5s to my home?” A traditional search engine might focus on finding matches for words — finding a page that says “buy” and “iPhone 5s,” for example.
Hummingbird should better focus on the meaning behind the words. It may better understand the actual location of your home, if you’ve shared that with Google. It might understand that “place” means you want a brick-and-mortar store. It might get that “iPhone 5s” is a particular type of electronic device carried by certain stores. Knowing all these meanings may help Google go beyond just finding pages with matching words.
In particular, Google said that Hummingbird is paying more attention to each word in a query, ensuring that the whole query — the whole sentence or conversation or meaning — is taken into account, rather than particular words. The goal is that pages matching the meaning do better, rather than pages matching just a few words.
I thought Google did this conversational search stuff already!
It does (see Google’s Impressive “Conversational Search” Goes Live On Chrome), but it had only been doing it really within its Knowledge Graph answers. Hummingbird is designed to apply the meaning technology to billions of pages from across the web, in addition to Knowledge Graph facts, which may bring back better results.
Does it really work? Any before-and-afters?
We don’t know. There’s no way to do a “before-and-after” ourselves, now. Pretty much, we only have Google’s word that Hummingbird is improving things. However, Google did offer some before-and-after examples of its own, that it says shows Hummingbird improvements.
A search for “acid reflux prescription” used to list a lot of drugs, which might not be necessarily be the best way to treat the disease. Now, Google says results have information about treatment in general, including whether you even need drugs, such as this as one of the listings.
A search for “pay your bills through citizens bank and trust bank” used to bring up the home page for Citizens Bank but now should return the specific page about paying bills
A search for “pizza hut calories per slice” used to list an answer, but not one from Pizza Hut. Now, it lists this answer directly from Pizza Hut itself, Google says.
Could it be making Google worse?
Almost certainly not. While we can’t say that Google’s gotten better, we do know that Hummingbird — if it has indeed been used for the past month — hasn’t sparked any wave of consumers complaining that Google’s results suddenly got bad. People complain when things get worse; they generally don’t notice when things improve.
Does this mean SEO is dead?
No, SEO is not yet again dead. In fact, Google’s saying there’s nothing new or different SEOs or publishers need to worry about. Guidance remains the same, it says: have original, high-quality content. Signals that have been important in the past remain important; Hummingbird just allows Google to process them in new and hopefully better ways.
Does this mean I’m going to lose traffic from Google?
If you haven’t in the past month, well, you came through Hummingbird unscathed. After all, it went live about a month ago. If you were going to have problems with it, you would have known by now.
By and large, there’s been no major outcry among publishers that they’ve lost rankings. This seems to support Google saying this is very much a query-by-query effect, one that may improve particular searches — particularly complex ones — rather than something that hits “head” terms that can, in turn, cause major traffic shifts.
But I did lose traffic!
Perhaps it was due to Hummingbird, but Google stressed that it could also be due to some of the other parts of its algorithm, which are always being changed, tweaked or improved. There’s no way to know.
