Most digital marketers understand that Google’s algorithm is a complex tool that can handle data at a massive scale.
You’re likely aware of terms like crawl, index, SERP, and more.
But in this post, I want to break down the 4 steps that the Google algorithm takes to discover, sort, and show content so you can have a better understanding of how Google works.
Once you understand each step in the algorithm you can better understand what Google is doing so you can create content and make it easier to find.
I’ve written in the past that product led SEO is NOT writing for algorithm or keywords but rather for a user’s intent.
However, it’s important to understand how Google thinks about content so you can make it easier to rank the content.
Let’s dive in.
Google’s algorithm for finding and indexing content involves several key components that work together to ensure relevant and useful search results are delivered. Here’s a breakdown of the four core parts.
1. Crawling
Google’s bots (often called “spiders” or “Googlebot”) continuously searches the web to discover new or updated content. These bots follow links from one webpage to another, trying to visit as many pages as possible. They start by crawling known websites and sitemaps, which webmasters can submit through tools like Google Search Console, but they also follow internal and external links to find deeper content.
Key Points:
- Googlebot discovers web pages through internal/external links.
- Crawls websites at different frequencies depending on their popularity and update rate.
- Webmasters can influence crawling by submitting sitemaps and using the
robots.txt
file to control which pages should or shouldn’t be crawled.
2. Indexing
Once a webpage is crawled, the content is processed and stored in Google’s index. This index is essentially a giant database of all the web pages Google knows about. During indexing, Google analyzes the text, images, videos, and metadata to understand what the page is about.
Key Points:
- Google looks at keywords, titles, meta descriptions, headers, and image alt tags.
- Structured data, such as schema markup, helps Google better understand the content.
- Pages deemed mobile-friendly and fast-loading tend to get indexed more favorably.
- Pages with restricted access (like those behind logins) or blocked via
robots.txt
won’t be indexed.
3. Ranking
Google uses hundreds of factors in its algorithm to determine the ranking of a page in search results. These ranking factors are often categorized into different areas like relevance, authority, and user experience. Some of the most critical ranking factors include keyword relevance, content quality, backlinks, page speed, and mobile-friendliness.
Key Points:
- Content relevance: Google ranks pages based on how well they match the user’s search query.
- Backlinks: High-quality backlinks from authoritative sites boost rankings.
- User experience: Page speed, mobile-friendliness, and secure (HTTPS) websites help improve rankings.
- Search intent: Understanding whether the user is looking for informational, transactional, or navigational content helps rank pages appropriately.
4. Serving Results
Once the pages are indexed and ranked, Google serves the most relevant results to users based on their search query. The goal is to provide the best possible match to what the user is looking for, considering things like location, device type, and the exact wording of the search query. Google’s search results also adapt over time through machine learning to improve accuracy.
Key Points:
- Personalization: Google tailors results based on the user’s previous searches, location, and language.
- Search features: Rich snippets, answer boxes, and featured snippets (which Google often pulls directly from a website’s content) are served to provide users with more context or a quick answer.
- Core Web Vitals: Page speed, interactivity, and visual stability also influence how content is served, especially on mobile devices.
These four components—crawling, indexing, ranking, and serving results—are all interrelated, forming the backbone of how Google finds, categorizes, and delivers relevant web content.
Key Takeaways
If you already knew all of the above – great. You have a good understanding of how Google’s search algo works and can apply it to your content marketing.
If this is new to you – the biggest areas to focus on are
- Create relevant content
- Create content for a specific user intent
- Make it easy to find the content
- Publish a tweet and link to the content
- Publish a linkedin post and link to the content
- Answer a question on reddit and or quora and link to the content (careful it’s not self promotion)
- Find a blog that allows guest posts and include your writing
The better you can get at writing really good content and finding places on the web that have a high likelihood of being crawled – you will see your content indexed and have a chance to be rewarded for it.
Happy writing ✍️.
