How Google’s Search Engine Really Works (A Peek Under The Hood)

how googles search engine really works

Google’s search engine is technically complicated.

There are a whole bunch (perhaps even 1000’s) of various elements taken under consideration in order that the search engine can determine what ought to go the place.

It’s like a mysterious black field, and only a few folks know precisely what’s inside.

However, the excellent news is that search engines like google are literally fairly simple to grasp.

We could not know each single issue (out of 100 or thousand), however we additionally don’t must.

I’ll convey it right down to the fundamentals with a easy technique to please Google, rank larger, and convey in additional web site site visitors.

I’ll additionally introduce among the newest developments, like RankMind, that assist Google guess what you’re really in search of (even in the event you don’t kind it in).

First, I’m going to stroll you thru precisely how Google’s search engine actually works to be able to see that it’s not as obscure as you may assume.

How Do Search Engines Crawl the Web?

Google’s first job is to ‘crawl’ the net with ‘spiders.’

These are little automated applications or bots that scour the online for any and all new data.

The spiders take notes in your web site, from the titles you employ to the textual content on every web page to be taught extra about who you might be, what you do, and who is perhaps enthusiastic about discovering you.

That could sound simplistic on the face of it.

Which is not any small feat, contemplating there are greater than 1.8 billion web sites on-line immediately — with 1000’s of latest websites popping up day by day.

The first huge problem is to find new knowledge, report what it’s about, after which retailer that data (with some accuracy) in a database.

Google’s subsequent job is to determine learn how to greatest match and show the knowledge in its database when somebody sorts in a search question. Scaling turns into an issue, although.

Google processes over 3.5 billion searches a day, and that quantity will increase yearly.

That means the knowledge in its database must be categorized appropriately, rearranged, and displayed in lower than a second after somebody expects it.

Time is of the essence right here, as a result of pace wins, in accordance with Marissa Mayer again when she labored for Google over a decade in the past.

She reported after they have been in a position to pace up Google Maps’ house web page (by reducing down on its measurement), site visitors leaped 10 % inside seven days and 25 % just some weeks later.

Google received the search engine race as a result of it’s in a position to:

  1. Find and report extra data
  2. Deliver extra correct outcomes
  3. Do each of these two duties sooner than another search engine

One of the explanations Google is the entrance of the pack comes right down to the accuracy of its outcomes.

The data it shows is extra more likely to match what customers are literally in search of.

Think about it this manner.

When you kind one thing into Google, you’re anticipating one thing. It is perhaps a easy reply, just like the climate in your metropolis, or perhaps a little bit extra complicated, like “how does Google’s search engine really work?”

Google’s outcomes, in comparison with different search engines like google, are likely to reply these queries higher. The data was the perfect of the perfect.

This breakthrough got here from an preliminary principle Google’s co-founders really labored on in faculty.

Why Do Links Matter to Google?

Google’s co-founders have been nonetheless at Stanford in 1998 after they launched a paper entitled “The PageRank Citation Ranking: Bringing Order to the Web.”

Check it out — you’ll be able to learn the entire thing proper right here!

how google words why links matter paper

The PageRank breakthrough was easy.

Academic papers have been usually ‘ranked’ by the variety of citations a paper acquired. The extra they acquired, the extra authoritative they have been thought-about on that subject.

Google co-founders, Larry Page and Sergey Brin, needed to use the identical ‘grading’ system to the net’s data. They used backlinks as a proxy for votes. The extra hyperlinks a web page acquired, the extra authoritative it was perceived on that specific subject.

links are votes how google works

Of course, they didn’t simply take a look at the quantity of hyperlinks. They additionally factored in high quality by contemplating who was doing the linking.

If you acquired two hyperlinks, for instance, from two completely different web sites, the one with the extra authority on a subject can be price extra.

They additionally thought-about relevance to raised gauge the ‘quality’ of a hyperlink.

For instance, in case your web site talks about “dog food,” hyperlinks from different pages or websites that speak about issues associated to “dogs” or “dog food” can be price extra than one speaking about “truck tires.”

External hyperlinks (hyperlinks from different websites) are additionally extra useful than inner hyperlinks (hyperlinks to completely different pages by yourself website.)

Before we go any additional, please perceive these ideas are over 20 years all.

PageRank could have mattered years in the past, however it’s advanced tremendously since then. So don’t fear about it explicitly immediately.

One of the explanations is due to newer algorithm developments, together with RankMind.

What is ‘RankBrain’ and How Does It Work?

RankMind was first acknowledged in 2015 by Google engineer Greg Corrado:

RankMind has turn into the third-most essential sign contributing to the results of a search question.

Google’s been engaged on this expertise for years to assist the search engine deal with the huge will increase in quantity with out shedding accuracy.

The RankMind secret sauce is that it makes use of synthetic intelligence to repeatedly discover ways to enhance.

So the extra it processes new data or new search queries for customers, it really will get extra correct.

For instance, in 2010, Google’s algorithm “might have up to 10,000 variations or sub-signals,” in accordance with Search Engine Land. That’s rather a lot!

As you’ll be able to think about, in some way managing all of these on the fly can be extremely troublesome (if not inconceivable).

That’s the place RankMind is available in.

Generally, the 2 most essential rating elements are:

  1. Links (and citations)
  2. Words (content material and queries)

Note: this adjustments over time, and these aren’t the one elements that matter. Speed performs a significant factor in Google rating, as do Core Web Vitals.

RankMind, nonetheless, remains to be a most important part. It helps analyze or perceive the connections between these hyperlinks and content material so Google can perceive the context behind what somebody’s asking. This is usually referred to as semantic search.

For instance, let’s say you kind within the phrase “engineer salaries.”

Now take into consideration that for a second. What kind of engineer salaries are you in search of?

It may very well be “civil,” “electrical,” “mechanical,” and even “software.”

That’s why Google wants to make use of a number of various factors to determine precisely what you’re asking for.

Let’s say the next occasions performed out over the previous few years:

  • You’re getting a level in pc science.
  • Your IP handle places you on the campus of Stanford University.
  • You observe tech journalists on Twitter.
  • You learn TechCrunch virtually each single day.
  • You Googled “software engineer jobs” final week.

Google’s in a position to piece all of those random bits of knowledge collectively. It’s like a bunch of puzzle items all of the sudden coming collectively.

So now Google is aware of what kind of “engineer salaries” to point out you, regardless that you by no means explicitly requested for “software engineer salaries.”

That’s additionally how Google is now answering your questions earlier than you even ask them.

For instance, do a generic search proper now for something, like “pizza.”

Now, what do you see?

how google words SERP example

You see the everyday advert areas up on the prime.

However, the native outcomes under the advertisements are assuming that you just’re asking “where to get pizza.”

The Knowledge Graph on the far right-hand aspect is serving up virtually each reality and determine about pizza possible.

RankMind course of and filters all this knowledge to provide you solutions earlier than you even ask them.

Change your search up a little bit (like this one for “pizza hut”) and the search engine outcome web page (SERP) adjustments with new data.

Now you know the way Google’s search engine actually works.

While you don’t have to be an professional, understanding the fundamentals like this will help you higher determine learn how to give your prospects precisely what they need (so that you get higher rankings and extra site visitors).

Here are just a few of the large issues to keep watch over.

How to Rank Higher in Google: Solve People’s Problems

People kind searches into Google to get a solution to no matter query they’re dealing with.

If they’re in search of a solution, it means they’ve a query.

If they’ve a query, it means they’ve an issue.

So your main job is to unravel somebody’s downside.

In principle, it’s actually that straightforward. If you resolve somebody’s downside higher than anybody else, you’ll get higher rankings and extra site visitors.

Let’s check out just a few examples so you’ll be able to see how this works in actual life.

Someone comes house from an extended day at work. All they’re trying ahead to doing is grabbing one thing to eat quick and hanging out with their household or watching a brand new present on Netflix.

Before they’re in a position to throw a meal collectively, they attempt to run the kitchen sink and uncover that it’s clogged.


It’s already getting late, although, in order that they don’t wish to name a plumber. Instead, they head over to Google and begin typing in “how to unclog drain” as their search question.

Then right here’s what they see:

how google works SERP example for how to uncolog a sink.


Way up on the prime is an advert for a plumber (simply in case you wish to name in an expert).

Next up is an Instant Answer field that accommodates step-by-step directions that Google believes has helped different folks. So you may already be capable of repair your sink with out ever leaving this web page!

Below which can be associated questions that different folks generally ask (together with their solutions).

So all of this begs the query: How do you create one thing that may assist resolve a person’s downside?

I’ll reply that in a single second, however right here’s what you don’t do for the report:

how google works example of keyword stuffing

“Keyword density” was an old-school tactic that was as soon as related when Google’s algorithm was dumb and static. With RankMind, Google has turn into a borderline genius.

So key phrase stuffing prefer it’s 1999 will damage you in the long term. As you’ll be able to see, it is a horrible “answer” or “solution” to somebody’s downside.

After saying that, there are just a few locations on a web page that you just wish to pay particular consideration to.

For instance, the Title Tag and Meta Description are utilized by Google to offer an official reply for what this web page is about.

Those are the 2 parts that can even present up on a SERP when somebody sorts of their question.

It solely is smart, then, that it’s best to use the primary subject in these areas so that everybody is aware of precisely what your web page is discussing.

how google works title tag and meta description

Do you wish to see the place that textual content is getting pulled from?

Simply right-click on an internet site to view the supply code. For instance, my homepage seems to be one thing like this:

where meta text is how google works

You can see the title tag and meta description on the prime of the code.

I’m additionally utilizing Yoast’s WordPress search engine optimization plugin to assist add these further fields on the bottom of WordPress.

That means, all it’s important to do is write out the particular title and outline in plain textual content (versus getting your arms soiled with code).

Otherwise, the precise web page content material needs to be written for people (versus key phrase stuffing to tips or idiot the major search engines).

Instead, right here’s how your web page content material ought to look:

how google works example of good content

I wrote an in-depth response to assist somebody determine an answer to a posh downside (key phrase analysis).

Even although it’s a posh topic, I used to be making an attempt to provide them a easy, step-by-step answer so they may repair that downside ASAP.

Google even takes web site utilization knowledge under consideration now to find out how useful your content material is.

For instance, let’s say that somebody clicks in your web site from Google and is turned off by the poor design or hard-to-read content material. So they ‘bounce back’ to Google instantly to discover a completely different outcome.

That’s a nasty signal! Google determines you weren’t a cheerful searcher. So perhaps Google will attempt to discover just a few different outcomes to swap out with that one to hopefully make everybody glad.

That’s why I additionally break up the paragraphs and embrace loads of pictures. The objective is to assist folks shortly discover what they’re in search of.

I need them to learn the web page sooner and digest the knowledge extra simply in order that they’ll stick round longer as a substitute of bouncing away.

That’s the important thing to rating nicely in search engines like google. Give the folks what they need, maintain them round or coming again for extra, and Google will likely be happier in consequence.

Let’s return to our clogged drain instance to see how this works in one other context.

Those are all fairly good outcomes!

In every case, the one who crafted every web page supplied an in depth reply to a typical downside.

Let’s zero in on that second SERP outcome, “7 Brilliant Ways to Unclog a Drain (Photos)” from Yahoo, to find what they’re doing so nicely to hit quantity two on an enormous, common search question like that.

This looks like it is perhaps outcome as a result of it offers us a number of strategies to strive, together with images so we will see precisely what’s occurring.

Let’s click on on that to see what they supply.

Pretty good general!

It supplies the person with good, high quality content material to assist resolve an issue. The higher your content material does that, the extra hyperlinks or ‘upvotes’ it’s going to obtain when different folks discover it helpful, too.

Links and different citations or social alerts assist alert Google. They inform the search engine that your web page is on the rise and to begin being attentive to your web site for these matters.

Your web page will get higher remedy, transfer up within the rankings, be uncovered to extra folks, get extra hyperlinks or votes in consequence, and proceed that upward pattern.

That’s the place the genius of Google’s course of comes into play.

It makes folks glad by giving them precisely what they’re in search of. When you do it proper, it offers you compounding advantages that may take off abruptly, increasing your web site site visitors in consequence.
