How Do Search Engines Work?
Pulling Back the Curtain on Google (and Others!)
I remember the moment in early 2001 when I realized that any question I had was fodder for searching on Google.
That realization changed the course of my life and many others as well.
And today, well, good grief, there's a lot of crap out there on the interwebs! And digging into it and finding the answers we're looking for has been Google's (and other search engine's) mission since day 1.
These insane machines have cataloged much of the world's knowledge into a database consisting of Exabytes (an Exabyte is 10K Petabytes, which is 10M Terabytes!) of searchable data.
Search engines operate using smart programs known as web crawlers, or digital "spiders", which trek through the vast landscape of the internet, following link trails to gather all sorts of information about each webpage.
And this is just the first step in a complex dance.
After gathering data, a search engine must organize everything into an almost unimaginably large database or index, arranging the chaotic sea of info into neat categories based on relevancy signals.
On the surface, it sounds like the most boring librarian task, but it's more akin to the detective work of Sherlock Holmes, piecing together clues hidden within the content of billions of web pages.
Here at Boomcycle Digital Marketing, my team and I make it our business to know those clues inside out.
The Process of Crawling Web Pages
The goal of web crawling is to find new web pages, the most up-to-date, relevant content, and to gather the most salient details about each page.
This includes extracting information about the content, its structure, relevance, quality, and much more, such as schema: a somewhat black art practiced by only the most geeked-out SEOs (like our team!)
When you launch a new website or publish fresh content, it's like opening a brand new shop in the endless ditchwater pudding of the internet. Web crawlers act as window shoppers - they move from one shop to another, inspecting products, services, rants, hot takes and price tags.
Similarly, web crawlers scrutinize web pages for relevant information that helps them understand what the page is all about.
As an SEO agency, the fine folks here at Boomcycle Digital Marketing specialize in optimizing websites to ensure efficient crawling and information digestion by search engine bots.
This involves various strategies, such as creating comprehensive sitemaps that provide clear pathways for web crawlers to navigate through a website, and sound site structure with plenty of juicy heading tag clues.
We also concentrate on resolving any crawling errors that might hinder the process and continually work on enhancing website architecture for smoother navigation.
This is quite nearly and endless hamster wheel of tasks.
But this intricate process not only sheds light on how search engines explore the vast landscape of the internet but also emphasizes the importance of optimizing websites for seamless crawling.
Indexing: The Cataloging of Websites
Imagine a librarian meticulously cataloging every book in the library, making it easy for you to find what you're looking for.
Similarly, search engines create an organized database of web pages to make finding information effortless for users.
This searchable database is known as an index.
Each record in the index contains crucial data about a webpage, allowing search engines to quickly (really, quite insanely quickly) retrieve relevant results when a user enters a query.
Creating this index involves gathering and storing important details from each webpage, including the content on the page, keywords, metadata, and other signals that help determine its relevance to specific search queries.
Just like a well-organized library index enables efficient retrieval of books, a carefully constructed webpage index is crucial for providing search engine users with accurate and relevant results.
It's akin to a massive digital filing cabinet where each drawer holds information about different topics. When a user looks for something specific, the search engine quickly sifts through this digital filing cabinet to provide the most relevant web pages.
For instance, if someone searches for "best pizza in San Ramon," (sadly, not much to find here!) the search engine uses its index to retrieve the tastiest web pages with content related to this query.
Here's where our expertise as an SEO agency comes into play.
We specialize in optimizing website content to ensure effective indexing and categorization by search engines.
By strategically incorporating relevant keywords, enhancing metadata, entity insertion, and improving overall page quality, we help ensure that our client's websites are accurately represented in the search engine's index.
So, understanding how search engines create and maintain their indexes is critical for anyone seeking to improve their online visibility. And this knowledge empowers businesses to enhance their online presence through such SEO practices.
Understanding Site Ranking
When you type something into a search engine and hit enter, do you ever wonder why some websites show up at the top and others are further down?
It's not by chance.
Every website is ranked according to its relevance and authority in relation to the search query.
(And -- just maybe -- Google includes a "randomness factor" to ensure we SEOs never quite know for certain how to rank pages.)
How Does Google Decide Which Sites Get Ranked Higher?
Well, this is the $1M question, ain't it?
Google aims to offer the best answers for your searches, so it doesn't just pick websites at random. It uses a complex algorithm that considers many factors to determine which sites should show up first.
There's a threadbare SEO aphorism that suggests that Google considers "over 200 ranking factors", but it's more than that.
One of the main things Google looks for is the quality of the content on a website. Is it useful and interesting? Does it answer common questions clearly and quickly? The better the content, the higher the site can rank.
But how would it hope to understand the quality of content when it's generally accepted that Google can't read?
The Role of User Engagement & User Signals
Google uses click data from their own search engine results pages as well as data from Chromium, their own open-source browser engine, to gather user signals. This was very much brought to light during testimony at the DoJ trial in 2023.
Those user signals, perhaps more than any other single factor, cause websites to rise and fall in the rankings.
Of course, there are lots of correlations with said user signals.
But as to causation, well, what could be simpler than letting its users "vote" for great web pages through their accumulated actions: someone who lingers on a page, scrolling (reading) the content, exploring additional pages on the site, watching a video, submitting a contact form and maybe even purchasing an item.
That's a quality user interaction, and a clear quality signal back to Google.
Backlinks: Links to Your Website from Other Websites
Another crucial factor is backlinks—these are links from other websites that point to your website. If a lot of other websites link to yours, Google sees that as a sign that your site is reliable and trustworthy.
The original way Google ranked pages was almost entirely based on their "RankBrain" algorithm. When RankBrain saw that a website had a lot of high-quality backlinks, it assumed that the website was also high-quality and relevant.
As a result, the website was ranked higher in Google's search results.
Links are one of the most important ranking factors today, serving as a signal flare to Google that oh, this web page might be important as it pertains to this topic.
Can a backlink be "topically relevant"? Well, yes.
When a web page that discusses pizza in San Ramon links to a pizza restaurant in San Ramon, that's a highly topically-relevant link. You can also goose the algorithm a little bit through the judicious use of anchor text.
For example, if instead of a link that pointed to the restaurant that said "Click here", you used the anchor text "Best pizza restaurant in San Ramon", the second link would carry with it a bit more topical weight in Google's eyes.
However, like everything in SEO, you must not overdo this, because Google will see this as a spam factor, and actually start to derank your site for "overoptimized anchor text".
I told ya this stuff was a bit complex!

Insight into Search Engine Algorithms
Search engine algorithms are like the secret recipes behind your favorite dishes—except, in this case, they determine which web pages show up when you search for something online. Through a complex mix of mathematics and logic, these algorithms sort through billions of web pages to find the most relevant results for your search query. So, what exactly goes into these algorithms?
To put it simply, search engine algorithms take into account a multitude of factors to rank web pages. This includes the relevance of keywords, the quality of content, the authority of the website, and the overall user experience. Hence, when you perform a search, the results are not random; rather, they are finely curated to match your intentions and provide the most accurate information.
Key Factors Considered by Search Engine Algorithms
For instance, if two websites have equally relevant content about chocolate cake recipes but one loads faster and is easier to navigate, it's likely that the latter may rank higher in search results due to a better user experience.
Understanding these fundamental aspects of how search engines work will not only help you comprehend their complex nature but also pave the way for smarter SEO strategies.
Exploring Different Search Engines
When we think of search engines, Google is usually the first name that comes to mind.
However, there are various other search engines out there, each with its distinctive way of ranking and displaying results. Bing, Yahoo, DuckDuckGo, Baidu—the list goes on. Each of these search engines has its own set of algorithms and ranking factors that determine the order in which websites appear in search results. It's not as simple as applying a one-size-fits-all approach to search engine optimization (SEO).
Understanding the specific ranking criteria and nuances of these different search engines is crucial for achieving comprehensive optimization. The more aware you are of their individual preferences and requirements, the better equipped you'll be to optimize your website for maximum visibility across multiple platforms.
For example, Bing has been known to favor older audiences in certain sectors (perhaps the ones who forget to change their default search engine to Google when setting up their new Windows computer!), while Yahoo often places a strong emphasis on social elements such as user engagement and shares.
Baidu, on the other hand, caters predominantly to the Chinese market.
And DuckDuckGo is laser-focused on user privacy.
My new favorite search engine is actually an AI-combo platter called perplexity.ai, which can do a variety of fun tricks related to finding and organizing the information it finds.
Imagine if we treated all search engines the same way; we'd be missing out on valuable opportunities to connect with users who prefer using alternative platforms. This could lead to missed connections and lost potential.
Our SEO experts understand the significance of tailoring optimization strategies for diverse search engines. By deeply grasping the intricacies unique to each platform, we can ensure that our client's websites achieve maximum visibility and engagement across various search engine results pages (SERPs).
Diving into the world of different search engines might seem overwhelming at first, but understanding their individual quirks is a key component of successful SEO strategies.
Decoding Primary Ranking Factors
First and foremost, content quality reigns supreme. When it comes to achieving high search engine rankings, the quality and relevance of content are paramount. It's rea`lly not just about incorporating keywords; it's about crafting engaging, informative, and valuable content that satisfies the user's search intent.
And how about adding a little bit of your own POV and experience? This killer app is called "information gain", and it's all the rage lately in SEO circles.
When information becomes a commodity (like cheaply-generated AI content), then information gain is the way you differentiate yourself from your competition.
There's lots of block-and-tackle stuff that you need to stay vigilant to.
Search engines closely examine the relevance of keywords within the content and its overall quality to ensure that users find what they are looking for.
Title tags play a crucial role in conveying the essence of a webpage to both users and search engines. These concise HTML elements provide a preview of the content while influencing click-through rates from search results (as long as Google doesn't rewrite them!) Crafting compelling and descriptive title tags that accurately reflect the page's content is vital for improving organic traffic.
Don't forget to craft an engaging meta description, too. You know, to give Google something else to rewrite.
Again, off-page factors hold considerable weight in determining a website's authority and trustworthiness. Backlinks serve as endorsements and significantly impact a site’s credibility in the eyes of search engines. Quality backlinks from reputable sources act as votes of confidence, indicating to search engines that your content is valuable and trustworthy.
A website’s backlink profile can be likened to references on a resume; the more credible sources vouching for your expertise and reliability, the more likely you are to be viewed favorably by search engines.
However, acquiring backlinks is an insane slog. It requires strategic outreach, lots of 'splainin', a bit of technical savvy on the other end, partnerships, and consistently producing high-quality content that naturally attracts links from other sites.
When it comes to technical aspects, mobile-friendliness has become increasingly influential in search engine rankings. With the surge in mobile usage, search engines prioritize displaying mobile-responsive websites to cater to users accessing information from their smartphones or tablets.
Check your Google Analytics and see how many of your visits come from mobile. Some of our clients receive upwards of 70% mobile traffic. Imagine if the business owners only viewed their websites on desktop.
Sadly, this often happens.
Ensuring that your website delivers an optimal user experience across various devices is essential for maintaining visibility in mobile search results.
Page load speed is another critical technical factor affecting a site’s ability to rank well on search engines. In today's fast-paced digital landscape, users expect instant access to information. Slow-loading pages can negatively impact user experience and lead to higher bounce rates, prompting search engines to deprioritize such web pages in their results.
At Boomcycle, we place significant emphasis on optimizing these primary ranking factors to enhance our clients' search engine visibility. By meticulously addressing content quality, leveraging strategic link-building initiatives, and ensuring technical excellence in mobile-friendliness and page load speed optimization, we empower businesses to secure prominent positions in search engine results—helping them connect effectively with their target audiences.
Topically-Relevant Keyword Generation and Role in Search
When you go to a library, what's the first thing you do? You probably look at the signs and labels to find where the books are about what you want, right?
Well, search engines are kind of like libraries, but instead of books, they organize millions of web pages. So, how do they know which web page to show when someone searches for something?
Keywords play a significant role.
Keywords are like road signs for search engines. When people type in a word or phrase, the search engine looks for those same words on websites. It uses those words to decide which pages are most relevant to what was searched for. And here's where things get interesting - not all keywords are created equal. Some keywords get searched more often than others, and some might not show the results you were hoping for when searched.
Importance of Relevant Topics and Keywords
Focusing on relevant topics (overarching concepts that may include dozens or hundreds of keywords) and keywords is crucial for getting your website noticed. This means using words and phrases that match what your audience is looking for. But how do you know what keywords will bring your website to the top of search results?
It might sound like guesswork, but it's actually based on a lot of research and data analysis. At Boomcycle Digital Marketing, our SEO specialists conduct thorough topical and keyword research to identify high-value target keywords that align with user search intent.
By finding out which words and phrases people use frequently, we can optimize your website content to include these terms naturally. This can make a big difference in how high up your website shows in search results. Using popular and relevant keywords helps improve your visibility and makes it easier for potential customers to find you online.
Some might think that stuffing as many keywords as possible into their content will help their website show up at the top of search results. But that's not necessarily true! Quality is just as important as quantity when it comes to keywords.
However, if you want to be found for the keyword "San Ramon", don't leave it to chance! Be sure to include that text on your web page.
Strategic Topical and Keyword Incorporation
Strategic incorporation of key topics and keywords involves striking a balance between using them naturally and not overdoing them. Search engines are smart - they can tell if you're trying too hard to cram as many keywords into your content as possible. In fact, such practices can even lead to penalties from search engines which push your site down in rankings.
Instead, a thoughtful approach is needed.
Keywords should be used sensibly within titles, headings, and naturally throughout the content, and topics should correspond to well-known entities. You can use Wikipedia as your sounding board for these purposes.
For example, if you use the term "pizza restaurant", you may wish to use the Wikipedia-preferred term "Pizzeria" instead, as this is the "entity" that Google's Knowledge Graph understands.
A sound topical focus helps search engines understand what your website is about and can improve its chances of appearing when users search for related topics.
Effective topic and keyword generation and their strategic incorporation into website content pave the way for improved visibility in search results while also enhancing user experience by providing relevant information based on their inquiries.
Understanding this dynamic interplay between topics, keywords and search engine algorithms empowers us to optimize websites effectively for better visibility and user engagement.

Frequently Asked Questions
What role do keywords play in search engine optimization?
Keywords play a crucial role in search engine optimization (SEO) as they help search engines understand the relevance of a webpage to a user's query. By accurately using relevant keywords on a webpage, you increase the chances of your website appearing as a top result on search engine result pages (SERPs). According to a study by Moz, keyword usage in page titles is one of the most important factors for SEO, with pages including target keywords ranking higher than those that don't. Effective keyword research and implementation can significantly improve your website's visibility and organic traffic.
Can search engines differentiate between reliable and unreliable sources of information?
Yes, search engines can differentiate between reliable and unreliable sources of information to provide users with credible results. They use complex algorithms that consider multiple factors to assess the credibility of a source, such as the authority, reputation, and expertise of the website or author, as well as user feedback and engagement metrics. Additionally, search engines continuously update their algorithms to combat misinformation and prioritize reliable sources. According to a study conducted by Stanford University in 2019, major search engines have made significant progress in improving the reliability of search results, leading to a decline in the visibility of unreliable information.
What is the algorithm behind search engine rankings?
The algorithm behind search engine rankings is a complex and ever-evolving process. At its core, search engines like Google use algorithms that analyze various factors, including keywords, relevance, and user experience, to determine the order in which websites appear in search results. While specific details of these algorithms are closely guarded secrets, Google has confirmed that elements such as high-quality content, backlinks, page speed, mobile-friendliness, and user engagement play significant roles in determining rankings. In fact, studies have shown that the top three organic search results on Google receive over 75% of all clicks, highlighting the importance of ranking highly in search engine results pages.
How do search engines determine which websites to display first in search results?
Search engines determine which websites to display first in search results based on a combination of factors such as relevance, popularity, and quality. Relevance is determined by analyzing the content of a website and how well it matches the search query. Popularity is measured by considering the number and quality of other websites that link to the site. Quality factors include user experience, load speed, mobile-friendliness, and security. While specific algorithms vary across search engines, this general approach aims to provide users with the most relevant and trustworthy information. According to Moz, a study shows that the top search result gets approximately 32% of all clicks, highlighting the significance of ranking high in search results.
How do search engines crawl and index web pages?
Search engines crawl and index web pages by using automated programs called crawlers or spiders. These programs start by discovering new web pages through links from other websites. Once a page is discovered, the crawler accesses the page's content and follows its links to find more pages. As it crawls, it collects information about each page, such as keywords, meta data, and page structure. This information is then indexed, allowing search engines to retrieve relevant results for user queries. Statistics show that Google alone has indexed over 130 trillion web pages, demonstrating the scale and efficiency of crawling and indexing processes.
