What are Google algorithm Updates?

💡 Google algorithms are intricate systems used to retrieve data from its search index and deliver the best possible results for a user’s query instantly.

These algorithms analyze a multitude of factors, like keywords, relevance, and usability of pages, the expertise of sources, and your location and settings. The weight applied to each factor varies depending on the nature of your query.

History of Google Algorithm Updates

To truly understand today’s SEO dynamics, let’s time travel through the key Google algorithm updates that have shaped the SEO landscape. We’ll begin from the most recent and move backward, offering essential takeaways at every juncture.

Core Web Vitals (2020): Emphasizing User Experience

Core Web Vitals was Google’s response to the growing importance of user experience. It’s a set of metrics aimed at evaluating crucial elements like loading speed (Largest Contentful Paint or LCP), interactivity (First Input Delay or FID, soon to be replaced by Interaction to Next Paint or INP), and visual stability (Cumulative Layout Shift or CLS).

Impact: This change implied that these performance parameters could significantly impact your website’s performance. For example, Farfetch, a luxury fashion retailer, saw a 1.3% conversion rate boost for every 100ms reduction in LCP.

BERT (2019): Understanding Language Better

Google’s BERT (Bidirectional Encoder Representations from Transformers) update was a significant leap in how the search engine understood the context and relationship between words in search queries.

Impact: The BERT update helped Google’s algorithm better understand and respond to more complex or conversational search queries.

Key Takeaway: As a content creator, writing in a natural, user-friendly language that aligns with Google’s improved understanding abilities is crucial.

Medic Update (2018): Strengthening E-A-T

The Medic Update brought E-A-T (Expertise, Authority, Trust) into the limelight, predominantly affecting health and wellness websites.

Impact: The update emphasized that websites should prioritize high-quality content rooted in solid expertise and trustworthy sources to build authority.

Key Takeaway: Enhancing your site’s E-A-T can significantly improve your ranking in Google’s eyes.

RankBrain (2015): AI Enters Search

RankBrain marked the integration of machine learning into Google’s search algorithm, making the search engine more intelligent and responsive.

Impact: RankBrain enhanced Google’s understanding of new or unique queries, increasing the importance of context and relevance in content creation.

Key Takeaway: To keep up with RankBrain, ensure your content is original, relevant, and updated regularly.

Mobilegeddon (2015): Emphasizing Mobile Compatibility

The Mobilegeddon update was Google’s way of emphasizing the crucial role of mobile-friendly websites in the modern digital space.

Impact: This update had a significant effect on mobile search rankings, with mobile-friendly websites seeing an uptick in their ranking.

Key Takeaway: Prioritize optimizing your website for a seamless mobile user experience.

Hummingbird (2013): Search Intent Gains Importance

Impact: Post-Hummingbird, content that effectively addressed users’ intent and answered their queries saw a significant boost in rankings.

Key Takeaway: Write content that addresses the user’s intent rather than just focusing on keyword usage.

Penguin (2012): Curtailing Unnatural Links

The Penguin update was Google’s effort to penalize sites using manipulative link-building techniques.

Impact: Websites using black-hat SEO techniques, such as link schemes, experienced a significant drop in rankings.

Key Takeaway: Maintain a diverse and natural link profile to stay in Penguin’s good books.

Panda (2011): Quality Content Reigns Supreme

Panda was Google’s push for websites to improve their content quality, penalizing those with thin, low-quality content.

Impact: Post-Panda, websites with high-quality, unique, and value-driven content saw a significant increase in their rankings.

Key Takeaway: Concentrate on creating valuable and unique content to remain Panda-friendly.

Major Algorithm Shifts: Florida (2003) & Jagger (2005)

The Florida and Jagger updates of the early 2000s aimed to reduce web spam and low-quality content.

Impact: These updates dropped the hammer on websites engaging in keyword stuffing and other spammy practices, redefining SEO strategies.

Key Takeaway: High-quality, user-friendly content never goes out of style.

PageRank (1998): Birth of Backlink Authority

PageRank was Google’s first algorithm, introduced to rank web pages based on the quality and quantity of backlinks.

Impact: While Google’s algorithm has evolved tremendously since then, PageRank’s legacy lives on as backlinks continue to be a significant ranking factor.

Key Takeaway: Secure high-quality backlinks from reputable sources to boost your website’s authority.

Latest Google Algorithm Updates: Reviews, Core Changes & Upcoming INP Metric

All About Google’s Product Review System Update

What Is It?

So, Google’s review system is all about quality. It loves reviews that are packed with insightful analysis, fresh research, and expert opinions. The goal? To serve up reviews with real depth rather than just surface-level summaries of products or services.

What Does It Evaluate?

The system checks out first-party content, like blog posts, articles, or pages that give recommendations, share opinions or offer analysis. What it doesn’t look at are third-party reviews, those written by users on a product page.

Reviews can cover almost anything – products, media, services, businesses; you name it. They can be about a single item, a head-to-head comparison, or even a ranked list of recommendations.

How Does It Work?

Usually, the review system takes a good look at the content of each page. If a website has comprehensive review content, it might check out the entire site. If there aren’t many reviews on a site, it’s less likely to do a site-wide evaluation.

This system works in a whole bunch of languages all over the globe – English, Spanish, German, French, Italian, Vietnamese, Indonesian, Russian, Dutch, Portuguese, Polish – you get the idea.

Updates and Your Site

Every now and then, Google tweaks the review system to make it better. When there’s a big change, they let everyone know with a “reviews update” on their Search Status Dashboard.

If a review update negatively affects your content, it may not recover until the next update is released. But remember, Google uses many factors to rank content so that changes could happen anytime.

All About Google’s Core Update

What Are They?

A few times a year, Google shakes things up with core updates. These are big, sweeping changes to their search algorithms and systems. The aim? To make sure they’re doing a top job at delivering helpful and reliable search results.

Impact of These Updates

Core updates don’t have any specific targets. They’re all about making the system for assessing content better. These changes can shuffle around some pages in the search results – and some might even do better if they were undervalued before.

Improving Your Content

Now, if your pages are doing worse after a core update, it doesn’t mean you’ve done anything wrong. Google’s advice is to focus on making your content as good as possible – that’s what the algorithms want.

Google offers a help page with questions you can ask yourself to ensure your content is top-notch. And if you’ve noticed a dip in performance, take some time to figure out why. Maybe other pages are doing a better job, or maybe you could use an honest critique from someone not connected to your site.

Bouncing Back From Core Updates

Broad-core updates happen every few months. If your content was affected, it might not recover until the next big update rolls.

Google is always improving its search algorithms, including smaller core updates. Smaller updates might not be widely announced, but they can boost your content if it deserves it. Remember, making improvements doesn’t guarantee recovery, and no page has a surefire spot in Google’s search results.

Upcoming Update: Interaction to Next Paint (INP)

What Is INP?

Expected to replace First Input Delay (FID) in March 2024, Interaction to Next Paint (INP) is a forthcoming Core Web Vital metric. INP measures how quickly a page reacts when a user interacts with it. It uses the Event Timing API, which tracks the time between the user’s action and the page’s response.

It then reports a single number that represents the speed of these interactions. In simpler terms, it tells us how fast a webpage responds to user actions. A low INP signifies the page consistently responds swiftly to most user interactions.

How Does INP Differ From FID?

While INP takes into account all page interactions, FID only focuses on the first one. FID measures the delay of the first interaction input, not the time taken to run event handlers or the delay in presenting the next frame. It essentially appraises the page’s first impression.

However, INP goes beyond just first impressions. By considering all interactions, INP provides a comprehensive responsiveness assessment, making it a more reliable indicator of overall responsiveness.

Tips for Staying Informed About Future Updates

  1. Follow Google’s official channels: Keep an eye on the Google Search Central Blog, the Google Search Liaison Twitter account, and other official channels for updates on algorithm changes.
  2. Subscribe to industry newsletters and blogs: Stay informed by subscribing to reputable SEO and digital marketing newsletters, blogs, or podcasts regularly discussing Google algorithm updates.
  3. Participate in SEO communities and forums: Join online SEO communities and forums, such as Webmaster World or SEO Roundtable, to discuss and stay updated on algorithm changes with other industry professionals.
  4. Monitor your website’s performance: Regularly check your website’s performance in Google Analytics and Google Search Console to identify any sudden changes that may indicate an algorithm update.
  5. Continuously improve your content: As Google’s algorithm evolves, focus on creating high-quality, user-centric content that provides value and adheres to best practices for SEO. This approach will help your website stay prepared for any future updates.

Final Thoughts on the Ever-Evolving World of SEO

Navigating the ever-evolving world of SEO is a continuous journey for website owners and publishers. It’s imperative to stay current with Google algorithm updates, as they shape the heart of your SEO strategies and directly impact your search visibility.

Regularly monitoring your website’s performance and being responsive to these changes is key. SEO is not static—it’s a journey of continuous learning and adaptation.
