On a side note anyone that’s wondering how to curate website content legally, ethically, and morally, at the bottom of this post is a great explanation on how this is done.
Anyone asking this question, “how does Google search work” will learn from one of the world’s leading experts, Matt Cutts! According to Matt, this is how Google search works. 1st I’m going to leave you the 3 minute video that Matt did on behalf of Google, then I’ll leave you the annotations.

Matt Cutts Annotation On How Google Search Works
So How Does Google Search Work? As quoted from Matt’s video:
“Id like to talk today, about what happens when you do a web search.
The 1st thing to understand, is that when you do a Google search, you aren’t actually searching the web. You’re searching Google’s index of the web, or … at least as much of it as we can find.
We do this with software programs called “spiders”.
Spiders start by fetching a few web pages, then they follow the links on those pages, and fetch the pages they point to. And follow all the links on those pages, and fetch the pages they link to, and so on, until we’ve indexed a pretty big chunk of the web, many billions of pages, stored across thousands of machines.
Now suppose I want to know how fast a cheetah can run. I type in my search say … cheetah … running … speed, and hit “return”.
Our software, searches our index, to find every page that includes those search terms. In this case, there are hundreds of thousands of possible results.
How does Google decide, which few documents I really want? By asking questions. More than 200 of them. Like:
- how many times does this page contain your “key” words?
- do the words appear in the title?
- in the URL?
- directly adjacent?
- does the page include synonyms for those words?
- is this page from a quality website, or is it low quality … even spammy?
- what is this page’s page rank?
That’s a formula, emitted by our founders Larry Page and Sergey Brin that rates a webpage’s importance by looking at how many outside links point to it, and how important those links are.
Finally, we combine all those factors together to produce each page’s overall score and send you back your search results. About half a second after you submit your search.
At Google, we take our commitment to delivering useful and impartial search results very seriously. We don’t ever accept payment to add a site to our index, update it more often, or improve its ranking.
Let’s take a look at my search results.
Each entry includes a title, a URL and a snippet of text to help me decide whether this page is what I’m looking for. I also see links to similar pages, Google’s most recent stored version of that page, and related searches that I might want to try next. And sometimes, along the right and at the top, I’ll see ads.
We take our advertising business very seriously as well, both our commitment to deliver the best possible audience for advertisers and to strive to only show ads that you really want to see.
We’re very careful to distinguish your ads from regular search results, and we won’t show you any ads at all if we can’t find any that we think will help you find the information you’re looking for – which, in this case, the cheetah’s top running speed, is more than 60 miles an hour”.
More On How Does Google Search Work And How YouTube Videos Can Be Curated
As for the question “how does Google search work”, I’ve never seen anyone explain it in as simple terms as Matt did above so let’s move on.
Lot’s of people wonder if it’s OK to use other people’s videos on their own website and the answer is yes! When the videos are uploaded there is a box where we can tick the option “Allow embedding’. If video creators don’t want anyone to use the videos they create, all they need to do is uncheck this box.
Now as for how to curate content, all I did for this blog post was transcribe the words that Matt was saying in his video, and his words alone gave me 499 words from a video that was only a bit longer than 3 minutes.
Search engines love blog posts with around 500 words, so we can take someone else’s 3 minute video and use them as content on our own website. Please notice that I did leave a copyright notice under the video and I did give proper credit where credit is due.
So thanks to Matt Cutts, Google, and YouTube I now have a blog post that adds more than 800 words of content, and a video that links directly to Google! Not to mention anyone who watched the video or read what Matt has to say will never have to ask the question, “How Does Google Search Work” again! Win – win!
So go out there and duplicate exactly what I just did and add page after page after page of content on your website!
