The Basics: How Google Finds and Ranks Pages
Google's search algorithm isn't just one algorithm but a collection of them working together through three main steps:
- Crawling: Google's web crawlers (sometimes called "spiders" or "bots") discover pages by following links from other websites or sitemaps. Think of them as digital explorers mapping the internet.
- Indexing: Once discovered, Google analyzes each page to understand what it's about, determines its quality, and decides whether to add it to the Google index—a massive database of webpages.
- Ranking: When you search for something, Google looks through its index and uses its algorithms to determine which pages are most relevant and helpful for your specific query.
Key Ranking Factors in 2025
1. Content Relevance
Content that directly addresses what people are searching for is more likely to rank well. Google has become incredibly sophisticated at understanding search intent, which falls into four main categories:
- Informational: When users want to learn something
- Commercial: When users are researching before making a purchase
- Transactional: When users want to take action like buying something
- Navigational: When users are looking for a specific website
To rank well, your content should include your target keywords naturally in your title tag, URL, H1 heading, meta description, and throughout your body text.
2. Content Quality and E-E-A-T
In 2025, Google heavily prioritizes content that demonstrates Experience, Expertise, Authoritativeness, and Trustworthiness (E-E-A-T). This means:
- Publishing genuinely useful information that satisfies search intent
- Adding unique value rather than repeating what exists elsewhere
- Citing credible, up-to-date sources
- Having content written or verified by subject matter experts
For example, health websites that show their content is written and reviewed by medical professionals tend to rank better than those without such credentials.

3. User Experience
Pages that provide excellent user experience rank higher in 2025. This means:
- Fast loading times (ideally under 2.5 seconds)
- Mobile-friendly design
- No intrusive pop-ups or excessive ads
- Clear navigation and logical site structure
- Secure connection (HTTPS)
Google's Core Web Vitals have become increasingly important, measuring loading performance, interactivity, and visual stability of your pages.
4. Backlinks
Links from other websites to your pages still function as "votes of confidence" in 2025. The more high-quality, relevant websites that link to your content, the better your chances of ranking well, especially for competitive keywords.
For example, a page about "spirulina benefits" with hundreds of quality backlinks from health and nutrition websites will typically outrank similar content with fewer links.
5. Topical Authority
Websites that demonstrate deep expertise in specific subjects gain Google's trust and rank better. Building topical authority involves creating comprehensive content clusters—groups of interlinked pages covering different aspects of the same topic.
For instance, a financial website like Investopedia ranks well for finance-related terms because it has thousands of in-depth pages covering various aspects of personal finance and investing.
6. Context and Personalization
In 2025, Google customizes search results based on:
- The searcher's location
- Device type (mobile vs. desktop)
- Search history
- Time of day
This means rankings aren't fixed—your page might rank differently for users in different cities or with different search histories.
Recent Algorithm Updates (2024-2025)
Google continuously refines its algorithm, with several major updates in recent years:
- March 2025 Spam Update: Enhanced detection of spammy tactics like expired domain exploitation and low-quality content publishing
- January 2025 Core Update: Introduced new algorithms to better assess AI-generated content and further refined ranking criteria
- August 2022 Helpful Content Update: Established a system to reward people-first content that provides genuine value
What To Do If Your Website Is Affected By an Algorithm Update
If you notice a sudden drop in rankings after an algorithm update:
- Confirm there was an update using Google's Search Status Dashboard or tools like Semrush Sensor
- Evaluate the impact by analyzing which pages were affected and what the update was targeting
- Make an action plan to improve your content based on what you've learned about the update
What's Changed in 2025
The spring 2025 updates have introduced several significant changes:
- Enhanced AI integration: Google's algorithm now better understands user intent and delivers more personalized, contextually relevant results

Common SEO Myths Debunked
Not everything you hear about Google's algorithm is true. These factors are NOT direct ranking signals:
- Domain age: Simply having an older website won't help you rank better
- Word count: There's no "perfect" length for content
- Keyword density: Using a keyword frequently doesn't make content more relevant
- Domain authority: While site trustworthiness matters, third-party metrics aren't used by Google
