Google Algorithms: A Complete Guide To Key Updates And Ranking Factors

The evolution of Google Algorithms has fundamentally changed how websites are ranked. From keyword-based strategies to more advanced algorithms that evaluate user experience and content quality, Google continues to refine how search results are determined. Major updates like BERT, Medic, and Core Web Vitals have introduced new benchmarks for SEO success, forcing webmasters and businesses to adapt.

At OctopusWriters, we’ve studied the most recent shifts in Google Algorithms and compiled this guide to help you navigate these changes. Read on to understand how these updates influence your site’s rankings and discover the best practices for staying visible in an ever-evolving digital world.

What Are Google Algorithms?

Google algorithms are the systems responsible for determining how websites rank in search results. These algorithms process data from web pages and aim to match users with the most relevant, high-quality results based on their search terms.

In essence, Google’s algorithms operate like any other algorithm: they collect and process information before ranking results. For instance, when you search for “cute cat videos” or “shoe stores in Pennsylvania,” Google’s complex system evaluates millions of web pages to provide the most accurate results.

While the exact details of Google’s algorithm are not public, we know a few factors that play a role:

• Keywords appearing in the title, header tags, and meta descriptions.
• The presence of natural backlinks to the page.
• The website’s ability to perform well on mobile devices.

These are just a handful of the factors Google’s algorithm considers when ranking pages, with numerous others influencing the final search results.

What Is A Google Algorithm For Search?

Google’s core algorithm is applied to each search, but it customizes the results based on the query’s specifics. Someone searching for “buy running shoes” will see entirely different results compared to someone searching for “cat videos.” Even slight changes in wording or spelling are enough to alter the results. Afterward, users are presented with tailored options to choose from, all happening incredibly fast.

At OctopusWriters, we understand how crucial this personalization is. Google’s algorithm has evolved to offer not just relevant results, but also predictive suggestions as you type. These suggestions are influenced by browsing history and other personal factors, reflecting the algorithm’s growing sophistication in providing personalized search experiences.

What Is A Google Algorithm For SEO?

As previously mentioned, Google’s algorithm uses keywords as one of the factors when determining search rankings. To rank well for specific keywords, applying SEO techniques is essential, as it helps Google identify the core topic of a webpage.

Years ago, it was common for websites to overload their content with keywords, assuming this would make them rank higher. However, Google soon adjusted its algorithm to penalize such keyword stuffing and other deceptive black hat SEO tactics.

It’s important to avoid using any techniques that aim to outsmart Google’s algorithm. While these tactics might work temporarily, Google will eventually detect them, and your site’s rankings will drop. Focus on following white hat SEO practices to ensure long-term success in search rankings.

Why Are Google Algorithms Important?

At the core of Google’s search functionality are algorithms, which enable the search engine to rank pages and understand the meaning behind search queries. These complex systems work by analyzing keywords, user intent, and other important factors to sort through billions of web pages and deliver accurate results.

Google’s algorithms do much more than match keywords to web pages. They assess content quality, site authority, and even user experience, such as how quickly a page loads or whether it’s mobile-friendly. This comprehensive approach ensures that users get the most relevant and trustworthy results every time they search.

How Does Google’s Algorithm Work?

Google’s algorithm processes and ranks web pages by considering several key factors:

• Meaning: Using advanced language models, Google corrects spelling errors and identifies synonyms to match search queries with the most relevant content. For example, it understands local search intent, like showing nearby cafes when searching for “coffee shops.”
• Relevance: Content relevance is determined by how well it matches the search query. An exact keyword match is a strong indicator of relevance, and user interaction data helps confirm this.
• Quality: Google evaluates the trustworthiness of content by looking at factors like backlinks from reputable sites and content depth. High-quality content is a key indicator of expertise and authority.
• Usability: Websites that are mobile-friendly, load quickly, and offer a good user experience are prioritized in search results. Features like HTTPS and minimal intrusive ads also play a role.
• Context: Google personalizes results by analyzing data like location, search history, and user preferences, ensuring tailored results.

With over 200 ranking factors, content creators should focus on optimizing measurable elements such as:

• Backlinks: The more high-quality backlinks, the more trustworthy your site appears to Google.
• Content Structure: Clear, well-organized content improves user experience and increases the chances of being featured in snippets.
• Meta Descriptions and Alt Text: Optimized meta descriptions and alt text help Google better understand the content.

By focusing on key ranking factors like content relevance, quality, and usability, you can significantly boost your site’s visibility and improve its overall performance in search rankings.

 

What Algorithms Does Google Use?

It’s likely that Google has several algorithms that haven’t been officially named or disclosed. However, here are the key ones we do know about:

Google Core Algorithm

The Google Core Algorithm serves as the backbone of Google’s search engine, orchestrating how billions of webpages are ranked for any given query. This core system works by integrating several specialized algorithms, each designed to assess factors such as content quality, keyword relevance, and user experience. These components come together to evaluate which pages should appear in the top search results, based on their alignment with user queries.

In addition to this primary function, the core algorithm incorporates algorithms that focus on technical aspects of websites, including site speed, mobile optimization, and HTTPS security. Google frequently updates the core algorithm to ensure that search results reflect current SEO standards and the latest user behavior patterns, keeping the search engine both relevant and effective.

Ranking Algorithm

This algorithm plays a crucial role in determining how pages are ranked on SERPs (Search Engine Results Pages). While many of its ranking factors remain unknown, a few key elements have been confirmed:

• Content quality: High-quality, informative content tends to perform well.
• Core Web Vitals: Metrics like page load time, interactivity, and visual stability influence ranking.
• HTTPS: Sites with secure connections are prioritized.
• Mobile optimization: Websites that work well on mobile devices rank higher.
• Site speed: Fast-loading pages enhance the user experience and improve rankings.
• Links: Internal and external links boost a site’s credibility and authority.
• Anchor text: Descriptive anchor text signals relevance to linked content.
• Geographical relevance: Local search results are influenced by the user’s physical location.

One of the most important updates to this algorithm was the Panda update in 2011, which targeted low-quality content and improved the visibility of high-quality websites.

PageRank

PageRank is an algorithm developed to evaluate a webpage’s importance by analyzing its backlink profile. By considering both the quantity and quality of the external links pointing to a page, it determines the page’s overall influence, helping rank it more effectively in search engine results.

Spam Algorithm

This algorithm is crucial for ensuring that Google’s search results remain accurate and trustworthy by detecting sites that breach Google’s Spam Policies. These sites often attempt to manipulate rankings using unethical methods like buying links or flooding content with irrelevant keywords. Once identified, these pages are either demoted in rankings or removed entirely from Google’s search index.

The Penguin update in 2012 marked a major advancement, targeting sites that exploited spammy SEO tactics to gain an unfair advantage in rankings. By penalizing these manipulative sites, Penguin helped ensure that users would find more authentic, useful content in their search results, promoting fairness in the SEO landscape.

RankBrain

RankBrain is a machine-learning algorithm that helps Google analyze and understand search queries better. An example would be a query like “running shoes for flat feet.” Even if the user doesn’t specify “supportive shoes,” RankBrain identifies that flat feet require extra support and surfaces results with recommendations for supportive footwear designed for this condition. This allows Google to deliver more accurate results, based on user needs rather than exact keyword matching.

Hilltop

Hilltop is an algorithm that helps Google identify relevant and authoritative content for specific keyword searches, particularly for news. Acquired by Google in 2003, Hilltop plays a key role in improving Google News by ranking authoritative documents higher in search results.

The algorithm determines authority by evaluating how many reputable pages link to a given document. This ensures that search results prioritize sources considered trustworthy, making it easier for users to find credible and up-to-date news on any given topic.

8 Major Google Algorithm Updates

While Google tweaks its search algorithm several thousand times annually, most of these changes are too subtle to even notice. Yet, occasionally, Google releases an update so significant that it reshapes the entire approach to SEO.

Google uses RankBrain to factor in broader contexts, such as synonyms, implied meanings, and personal search histories, making it one of the top three ranking factors today. This allows pages to rank even when they don’t contain the exact search terms but meet the user’s intent.
• How to adjust: To stay competitive, focus on creating content that’s both comprehensive and highly relevant to your audience. Leverage tools like WebSite Auditor’s TF-IDF to analyze the terms used by top-performing competitors. Incorporating these terms into your content will help you stay aligned with RankBrain’s focus on relevance and depth.

RankBrain emphasizes the importance of creating content that truly meets user intent. By keeping relevance and quality at the forefront of your SEO strategy, you’ll be better positioned to succeed in Google’s evolving search landscape.

Medic

In May 2018, Google rolled out the Medic update, significantly affecting websites that provide life-impacting information, known as YMYL (Your Money or Your Life) sites. The update emphasized the importance of authority, expertise, and trustworthiness.

• Date: May 4, 2018
• Risks: Insufficient authority on YMYL websites; weak E-A-T signals.
• How it works: The Medic update primarily impacted medical, financial, legal, and educational websites. While Google hasn’t fully detailed the update’s mechanics, it’s widely believed that it strengthened the role of E-A-T (Expertise, Authority, Trust) in determining rankings for these types of sites.
• How to adapt: To recover from this update, many SEOs suggest improving the credibility of your content by working with expert contributors. Building brand authority through strong backlink profiles is also essential. Using tools like SEO SpyGlass can help you find link-building opportunities by identifying high-authority sites already linking to your competitors.

SEO SpyGlass helps pinpoint potential backlinks by analyzing where your competitors are being linked, especially from high-authority sites that are active in your niche.

Bert

The BERT update from Google in 2019 marked a significant leap forward in search engine optimization, emphasizing the importance of user intent and contextual relevance in search results.

• Date: October 22, 2019
• Risks: Poorly crafted content, lack of focus, and inadequate context.
• How it works: By employing natural language processing, BERT enables Google to interpret queries beyond just keywords. It identifies relationships between words and entities to provide more relevant results. This update builds upon previous changes like Panda and RankBrain, enhancing Google’s ability to interpret meaning and context.
• How to adjust: To adapt, ensure your content is clear and user-focused, using relevant terms and concepts that add context and depth. Avoid keyword stuffing and instead, concentrate on creating meaningful content that matches user intent.

BERT is a step forward in refining search results based on context. Creating content that aligns with these new standards will improve both user satisfaction and search visibility.

Core Updates

Since 2017, Google’s core updates have become routine but remain largely ambiguous. These updates are designed to improve search quality but are not always fully explained to the public.
