Googleโs search engine is technically complex.
There are hundreds (maybe even thousands) of different factors taken into account so that the search engine can figure out whatย should go where.
Itโs like a mysterious black box, and very few people know exactly whatโs inside.
However, the good news is that search engines are actually pretty easy to understand.
We may not know every single factor (out of a hundred or thousand), but we also donโt need to.
Iโll bring it down to the basics with a simple method to please Google, rank higher, andย bring in more website traffic.
Iโll also introduce some of the latest developments, like RankBrain, that help Google guessย what youโre actually looking for (even if you donโt type it in).
First, Iโm going to walk you through exactly how Googleโs search engine really works so that you can see that itโs not as difficult to understand as you might think.
How Do Search Engines Crawl the Web?
Googleโs first job is to โcrawlโ the web with โspiders.โ
These are little automated programs or bots that scour the net for any and all new information.
The spidersย take notes on your website, from the titles you use to the text on each page to learn more about who you are, what you do, and who might be interested in finding you.
That may sound simplistic on the face of it.
Which is no small feat, considering there are more than 1.8 billion websites online today โ with thousands of new sites popping up every day.
The first massive challenge is to locateย new data, record what itโs about, and then store that information (with some accuracy) in a database.
Googleโs next job is to figure out how to best match and display the information in its database when someone types in a search query. Scaling becomes a problem, though.
Google processes over 3.5 billion searches a day, and that number increases every year.
That means the information in its database needs to be categorized correctly, rearranged, and displayed in less than a second after someone expects it.
Time is of the essence here, because speed wins, according to Marissa Mayerย back when she worked for Google over a decade ago.
She reportedย when they were able to speed up Google Mapsโ home page (by cutting down on its size), traffic leaped 10 percent within seven days and 25 percent just a few weeks later.
Google won the search engine race because itโs able to:
- Find and record more information
- Deliver more accurate results
- Do both of those two tasks faster than any other search engine
One of the reasons Google is the front of the pack comes down to the accuracy of its results.
The information it displays is more likely to match what users are actually looking for.
Think about it this way.
When you type something into Google, youโre expectingย something. It might be a simple answer, like the weather in your city, or maybe a littleย more complex, like โhow does Googleโs search engine really work?โ
Googleโs results, compared to other search engines, tend to answer those queries better. The information was the best of the best.
This breakthrough came from an initial theory Googleโs co-founders actually worked on in college.
Why Do Links Matter to Google?
Googleโs co-founders were still at Stanford in 1998 when they released a paper entitled โThe PageRank Citation Ranking: Bringing Order to the Web.โ
Check it out โ you can read the whole thing right here!
The PageRank breakthrough was simple.
Academic papers were often โrankedโ by the number of citations a paper received. The more they received, the more authoritative theyย were considered on that topic.
Google co-founders, Larry Page and Sergey Brin, wanted to apply the same โgradingโ system to the webโs information. They used backlinks as a proxy for votes.ย The more links a page received, the more authoritative it was perceived on that particular topic.
Of course, they didnโt just look at the numberย of links. They also factored in quality by considering who was doing the linking.
If you received two links, for example, from two different websites, the one with the more authority on a topic would be worth more.
They also considered relevanceย to better gauge the โqualityโ of a link.
For example, if your website talks about โdog food,โ links from other pages or sites that talk about things related to โdogsโ or โdog foodโ would be worth moreย than one talking about โtruck tires.โ
External links (links from other sites) are also more valuable than internal links (links to different pages on your own site.)
Before we go any further, please understand these concepts are over two decades all.
PageRank may have mattered years ago, but itโs evolved tremendously since then. So donโt worry about it explicitly today.
One of the reasons is because of newer algorithm developments, including RankBrain.
What is โRankBrainโ and How Does It Work?
RankBrainย was first acknowledged in 2015 by Google engineer Greg Corrado:
RankBrain has become the third-most important signal contributing to the result of a search query.
Googleโs been working on this technology for years to help the search engine handle the massive increases in volume without losing accuracy.
Theย RankBrain secret sauce is that it uses artificial intelligenceย to continually learn how to improve.
So the more it processes new information or new search queries for users, it actually gets more accurate.
For example, in 2010, Googleโs algorithm โmight have up to 10,000 variations or sub-signals,โ according to Search Engine Land. Thatโs a lot!
As you can imagine, somehow managing all of those on the fly would be incredibly difficult (if not impossible).
Thatโs where RankBrain comes in.
Generally, the two most important ranking factors are:
- Links (and citations)
- Words (content and queries)
Note: this changes over time, and these arenโt the only factors that matter. Speed plays a major factor in Google ranking, as do Core Web Vitals.
RankBrain, however, is still a main component. It helps analyze or understand the connections between those links and content so Google can understand the context behind what someoneโs asking. This is often called semantic search.
For example, letโs say you type in the word โengineer salaries.โ
Now think about that for a moment. What type of engineer salaries are you looking for?
It could be โcivil,โ โelectrical,โ โmechanical,โ or even โsoftware.โ
Thatโs why Google needs to use several different factors to figure out exactly what youโre asking for.
Letโs say the following events played out over the past few years:
- Youโre getting a degree in computer science.
- Your IP address puts you on the campus of Stanford University.
- You follow tech journalists on Twitter.
- You read TechCrunch almost every single day.
- You Googledย โsoftware engineer jobsโ last week.
Googleโs able to piece all of these random bits of data together. Itโs like a bunch of puzzle pieces suddenly coming together.
So now Google knows what type of โengineer salariesโ to show you, even though you never explicitly asked for โsoftware engineer salaries.โ
Thatโs also how Google is now answering your questions before you even ask them.
For example, do a generic search right now for anything, like โpizza.โ
Now, what do you see?
You see the typical ad spaces up at the top.
However, the local results below the ads are assuming that youโre asking โwhere to get pizza.โ
The Knowledge Graphย on the far right-hand side is serving up almost every fact and figure about pizza imaginable.
RankBrain process and filters all this data to give you answers before you even ask them.
Change your search up a little (like this one for โpizza hutโ) and the search engine result page (SERP) changes with new information.
Now you know how Googleโs search engine really works.
While you donโt need to be an expert, understanding the basics like this can help you better figure out how to give your prospects exactly what they want (so you get better rankings and more traffic).
Here are a few of the big things to keep an eye on.
How to Rank Higher in Google: Solve Peopleโs Problems
People type searches into Google to get an answer to whatever question theyโre facing.
If theyโre looking for an answer, it means they have a question.
If they have a question, it means they have a problem.
So your primary job is to solve someoneโs problem.
In theory, itโs really that simple. If you solve someoneโs problem better than anyone else, youโll get better rankings and more traffic.
Letโs take a look at a few examples so you can see how this works in real life.
Someone comes home from a long day at work. All theyโre looking forward to doing is grabbing something to eat fast and hanging out with their family or watching a new show on Netflix.
Before theyโre able to throw a meal together, they try to run the kitchen sink and discover that itโs clogged.
Bummer.
Itโs already getting late, though, so they donโt want to call a plumber. Instead, they head over to Google and start typing in โhow to unclog drainโ as their search query.
Then hereโs what they see:
See?!
Way up at the top is an ad for a plumber (just in case you want to call in a professional).
Next up is an Instant Answer box that contains step-by-step instructions that Google believes has helped other people. So you might already be able to fix your sink without ever leaving this page!
Below that are related questions that other people commonly ask (along with their answers).
So all of this begs the question: How do you create something that can help solve a userโs problem?
Iโll answer that in one second, but hereโs what youย donโt do for the record:
โKeyword densityโ used to be an old-school tactic that was once relevant when Googleโs algorithm was dumb and static. With RankBrain, Google has become a borderline genius.
So keyword stuffing like itโs 1999 will hurt you in the long run. As you can see, this is a terrible โanswerโ or โsolutionโ to someoneโs problem.
After saying that, there are a few places on a page that you want to pay special attention to.
For example, the Title Tagย and Meta Descriptionย are used by Google to provide an official answer for what this page is about.
Those are the two elements that will also show up on a SERP when someone types in their query.
It only makes sense, then, that you should use the main topic in those areas so that everyone knows exactly what your page is discussing.
Do you want to see where that text is getting pulled from?
Simply right-click on a website to view the source code. For example, my homepage looks something like this:
You can see the title tag and meta description at the top of the code.
Iโm also using Yoastโs WordPress SEOย plugin to help add these extra fields on the backside of WordPress.
That way, all you have to do is write out the specific title and description in plain text (as opposed to getting your hands dirty with code).
Otherwise, the actual page content should be written for humans (as opposed to keyword stuffing to tricks or fool the search engines).
Instead, hereโs how your page content should look:
I wrote an in-depth response to help someone figure out a solution to a complex problem (keyword research).
Even though itโs a complex subject, I was trying to give them a simple, step-by-step solution so they could fix that problem ASAP.
Google even takes website usage dataย into account now to determine how helpful your content is.
For example, letโs say that someone clicks on your website from Google and is turned off by the poor design or hard-to-read content. So they โbounce backโ to Google immediately to find a different result.
Thatโs a bad sign! Google determines you werenโt a happy searcher. So maybe Google will try to find a few other results to swap out with that one to hopefully make everyone happy.
Thatโs why I also break up the paragraphs and include a lot of images. The goal is to help people quickly find what theyโre looking for.
I want them to read the page faster and digest the information more easily so that theyโll stick around longer instead of bouncing away.
Thatโs the key to ranking well in search engines. Give the people what they want, keep them around or coming back for more, and Google will be happier as a result.
Letโs go back to our clogged drain example to see how this works in another context.
Those are all pretty good results!
In each case, the person who crafted each page provided a detailed answer to a common problem.
Letโs zero in on that second SERP result, โ7 Brilliant Ways to Unclog a Drain (Photos)โ from Yahoo, to discover what theyโre doing so well to hit number two on a big, popular search query like that.
This seems like it might be a good result because it gives us multiple methods to try, along with photos so we can see exactly whatโs happening.
Letโs click on that to see what they provide.
Pretty good overall!
It provides the user with good, quality content to help solve a problem. The better your content does that, the more links or โupvotesโ it will receive when other people find it useful, too.
Links and other citations or social signals help alert Google. They tell the search engine that your page is on the rise and to start paying attention to your website for these topics.
Your page will get better treatment, move up in the rankings, be exposed to more people, get more links or votes as a result, and continue that upward trend.
Thatโs where the genius of Googleโs process comes into play.
It makes people happy by giving them exactly what theyโre looking for. When you do it right, it gives you compounding benefits that can take off all of a sudden, expanding your website traffic as a result.
