Ranking in Google Search Generative Experience (SGE): Insights from Gary Illyes at SEOday 2024

Google‘s Search Generative Experience (SGE) is ushering in a new era of search powered by artificial intelligence (AI). As AI reshapes how information is delivered to users, it‘s also redefining the principles and strategies of search engine optimization (SEO).

At the forefront of this shift is Google‘s Webmaster Trends Analyst, Gary Illyes. With over 15 years of experience at Google working on search quality and webspam, Illyes has an unparalleled understanding of how Google‘s algorithms evaluate and rank web content.

His recent revelations at SEOday 2024 in Denmark provide a glimpse into the future of search and invaluable guidance for SEOs looking to adapt and thrive in an AI-driven search landscape. Let‘s unpack the key insights from his talk and explore what they mean for SEO moving forward.

The AI Search Revolution

To grasp the significance of Illyes‘ disclosures, it‘s important to understand the rapid advancement and adoption of AI in search. A 2022 study by Statista found that the global AI market is expected to reach $126 billion by 2025, growing at a compound annual growth rate (CAGR) of 43.6% from 2021 to 2025.

Search is one of the primary drivers of this growth. Google has been at the vanguard, integrating AI and machine learning into its search algorithms for years with innovations like RankBrain and BERT. However, the launch of SGE marks a major leap forward in the use of generative AI to provide direct answers and contextual results.

As Illyes noted, "With SGE, we‘re not just organizing information anymore. We‘re creating it. This changes everything for search and SEO." Indeed, a 2023 survey by BrightEdge found that 71% of marketers believe AI will have a significant impact on SEO in the next 3 years.

Clicks, Engagement, and Rankings

One of the most striking revelations from Illyes was how user clicks and engagement influence search rankings in nuanced ways. Contrary to popular belief, Google doesn‘t use traditional click-through rate (CTR) data to rank pages. However, they do pay close attention to how users interact with search results.

"We look at clicks, but not in the way most people think," Illyes explained. "It‘s not just about getting the click. It‘s about what happens after the click." Google‘s algorithms evaluate post-click engagement signals like dwell time, bounce rate, and pogo-sticking to determine how well a page satisfies user intent.

Engagement Metric	Definition	Impact on Rankings
Dwell Time	The amount of time a user spends on a page after clicking through from the search results.	Longer dwell times suggest the content is engaging and relevant to the query, which can positively impact rankings.
Bounce Rate	The percentage of visitors who leave a website after viewing only one page.	A high bounce rate can indicate that a page isn‘t meeting user expectations, potentially harming rankings.
Pogo-sticking	When a user clicks on a search result, quickly returns to the SERP, and clicks on a different result.	Frequent pogo-sticking tells Google that a result isn‘t satisfying users, which may result in lower rankings.

This emphasis on engagement aligns with Google‘s core mission of delivering the most relevant and useful results to searchers. As Illyes put it, "Our goal is to get users to their answer as quickly as possible. If they‘re bouncing back to the SERP or pogo-sticking, that‘s a bad experience."

For SEOs, this underscores the importance of creating content that doesn‘t just rank, but also engages. It‘s not enough to optimize for keywords and earn the click. The real goal is to provide value and fulfill the user‘s intent so well that they don‘t feel the need to return to the SERP.

Tactics like using appealing meta descriptions to boost CTR still matter, but they must be backed up by substantial, user-centric content. Prioritizing user experience metrics like dwell time and bounce rate will be key to ranking success moving forward.

The Enduring Importance of Keywords and Semantics

While user engagement signals are undoubtedly gaining weight, Illyes stressed that keywords and semantics remain foundational to how Google understands and ranks content. Even as search algorithms become more sophisticated, they still rely on language to connect queries to relevant results.

"Computers don‘t understand content the way humans do," Illyes said. "They‘re looking for semantic matches, not just exact keywords." This distinction is crucial for SEOs to grasp. Keyword stuffing and over-optimization are not only ineffective, but can actually harm rankings.

Instead, the focus should be on creating content that naturally incorporates relevant terms and their semantic variations in a way that‘s useful and engaging for humans. This approach aligns with Google‘s Natural Language Processing (NLP) capabilities, which have become increasingly adept at understanding context and user intent.

Advancements like Google‘s BERT (Bidirectional Encoder Representations from Transformers) allow the search engine to better grasp the nuances of language and the relationships between words. Introduced in 2019, BERT can discern subtle differences in word sense based on the other words used around them.

For example, in the phrase "I got my license to drive," BERT understands that "license" refers to a driver‘s license, not a software license or a license to practice law. This contextual understanding enables Google to deliver more relevant results for conversational and long-tail queries.

As NLP models continue to evolve, SEOs must adapt their keyword strategies to focus on topical depth and semantic richness rather than strict keyword matching. Content should be crafted to thoroughly answer questions and cover topics from multiple angles, using natural language.

Tools like Google‘s Natural Language API can help SEOs analyze their content‘s semantic structure and identify opportunities to optimize for relevance and intent. By aligning content with Google‘s NLP capabilities, SEOs can improve their chances of ranking for a wider variety of queries and providing value to users.

E-E-A-T and Google‘s Quality Rater Guidelines

Another key theme from Illyes‘ talk was the continued importance of expertise, authoritativeness, and trustworthiness (E-A-T) as a ranking factor. While E-A-T isn‘t a direct ranking signal, it heavily influences how Google‘s algorithms assess content quality and credibility.

"E-A-T is really about understanding if a page is a reliable source for the topic it covers," Illyes explained. "It‘s not just about the author‘s credentials, but also the site‘s reputation and the quality of the content itself." This holistic view of E-A-T is reflected in Google‘s Search Quality Rater Guidelines (QRGs).

The QRGs are a set of instructions provided to human raters who evaluate the quality of Google‘s search results. While raters don‘t directly impact rankings, their feedback is used to improve Google‘s algorithms and inform the development of new ranking signals.

In 2022, Google updated the QRGs to place greater emphasis on the "E" in E-A-T, renaming it "E-E-A-T" (with the extra "E" signifying "experience"). This change underscores the growing importance of first-hand expertise and real-world experience in assessing content quality.

For example, the guidelines state that "high E-E-A-T medical advice should be written by people or organizations with appropriate medical expertise or accreditation." Similarly, they advise that "high E-E-A-T financial advice, legal advice, tax advice, etc., should come from trustworthy sources and be maintained and updated regularly."

To optimize for E-E-A-T, SEOs should focus on:

Building author expertise through bylines, bios, and links to authoritative profiles.
Demonstrating first-hand experience through case studies, original research, and real-world examples.
Enhancing site authority through quality backlinks, brand mentions, and positive reviews.
Ensuring content accuracy through fact-checking, citations, and regular updates.
Providing clear information on content authors, site owners, and content policies.

By aligning content with Google‘s E-E-A-T standards, SEOs can build trust and credibility with both users and search engines. As Illyes noted, "In a world of misinformation and AI-generated content, E-E-A-T is more important than ever. It‘s how we ensure our results are reliable and useful."

The Rise of AI-Generated Content

The proliferation of AI-powered content creation tools like ChatGPT has raised questions about the role of machine-generated content in search. While these tools can produce content quickly and cost-effectively, Illyes cautioned against relying on them too heavily.

"AI content generators are getting better, but they still struggle with factual accuracy and original insights," he said. "They‘re great for ideation and rough drafts, but they need human oversight to ensure quality." This aligns with Google‘s stance on auto-generated content.

In a 2022 blog post, Google‘s Search Advocate John Mueller wrote, "Using machine learning and AI to generate content with primarily search engine rankings in mind is against our long-standing spam policies." He added that Google‘s focus is on rewarding "high-quality, people-first content" that demonstrates E-E-A-T.

However, this doesn‘t mean AI has no place in SEO. When used strategically and with human curation, AI can help streamline content workflows and improve content quality. For example:

AI-powered research tools can surface relevant data points and insights to inform content briefs.
Language models can help ideate new content angles and suggest semantic keywords to target.
AI writing assistants can help optimize content structure, readability, and tone.
Machine learning algorithms can analyze content performance and provide optimization recommendations.

The key is to view AI as an enhancement to human expertise, not a replacement for it. By combining the efficiency of machine learning with the critical thinking and creativity of human writers, SEOs can craft content that is both engaging and authoritative.

As Illyes put it, "AI is a tool, not a solution. It‘s up to humans to use it ethically and responsibly to create content that truly serves users." By keeping people at the center of AI-assisted SEO, marketers can harness the power of machine learning without sacrificing quality or trust.

Preparing for an AI-Driven Search Future

Looking ahead, it‘s clear that AI will continue to reshape search in profound ways. Google is already developing more advanced AI models like the Multitask Unified Model (MUM), which can understand and generate content across 75 languages and multiple modalities (text, images, video, and audio).

According to Google, MUM is 1,000 times more powerful than BERT and can handle complex queries that require synthesizing information from multiple sources. For example, a query like "I‘ve hiked Mt. Adams and now want to hike Mt. Fuji next fall, what should I do differently to prepare?" would stump most search engines today. But MUM could understand the intent behind the query and provide a comprehensive answer drawing from various hiking guides, travel blogs, and local weather reports.

As MUM and similar technologies become more integrated into search, SEOs will need to adapt their strategies to focus on:

Topical depth and breadth: Providing comprehensive coverage of topics to satisfy complex queries.
Multimedia optimization: Ensuring content is optimized across text, images, video, and audio formats.
Entity-based optimization: Structuring content around entities (people, places, things) and their relationships.
User intent and experience: Aligning content with user needs and providing intuitive, engaging experiences.
Brand authority and expertise: Building brand credibility and thought leadership through original research and insights.

By staying attuned to the latest AI developments and adapting strategies accordingly, SEOs can future-proof their efforts and maintain a competitive edge. As Illyes advised, "The fundamentals of SEO still apply, but the application is evolving. The most successful SEOs will be those who can blend technical savvy with a deep understanding of users and adapt quickly to change."
