Mastering Entity SEO: Strategies for the Search Engine 3.0 Era

Summary of This Atrticle: This article explores the transition from “search engine 2.0” to “search engine 3.0,” focusing on the introduction of entities in SEO. It discusses the evolution of search engines, the impact of entities on query processing and document ranking, and how SEO professionals can adapt their strategies to thrive in this new era.

Navigating the Shift from Keywords to Entities in SEO

The landscape of search engine optimization (SEO) has undergone significant changes over the years. One of the most impactful shifts has been the transition from “search engine 2.0” to “search engine 3.0,” marked by the introduction of entities. This article aims to explore these changes, the impact of entities on modern SEO, and how to adapt your strategies to thrive in this new era.

Building Your Own SEO ‘Notional Machine’

A ‘notional machine’ is a mental model of how a system works. In the context of SEO, it’s our understanding of how search engines operate. The more detailed and accurate this mental model is, the better equipped we are to tackle new problems and drive results

With the introduction of entity SEO, several major components within Google’s search engine were altered. Entity SEO introduces vocabulary and concepts that originate from machine learning and information retrieval disciplines. These terms may seem complex, but once we distill them, the concepts are not overly complicated.

• Example: A developer’s notional machine of a computer system helps them understand how their code will be executed. Similarly, an SEO professional’s notional machine of a search engine helps them understand how their strategies will impact search results.

From Search Engine 1.0 to 2.0

In the beginning, search engines operated on a simple “bag of words” model. This model treated a document as a mere collection of words, neglecting the contextual meaning or arrangement of these words. With the advent of “search engine 2.0,” Google adopted more sophisticated strategies. Instead of just matching words, this iteration aimed to decipher the user’s intent behind their query.

• Example: If a user searched for “jaguar,” the engine could now consider the user’s search history and location to infer the likely context. If the user had been searching for car models, the engine might prioritize results about the car brand over the animal or the football team.

Search Engine 2.0 vs. 3.0

As we transitioned from “search engine 1.0” to “search engine 2.0”, we had to update our mental models and change our practices. In the era of “search engine 3.0”, it’s clear that the mental shift to accommodate these changes is still in progress. Many concepts from the 2.0 era persist, largely because practitioners need time to observe the correlation between their adjustments and the subsequent outcomes.

• Example: In the era of “search engine 2.0”, the quality of backlinks became crucial, prompting SEO professionals to seek backlinks from higher-quality websites. In the era of “search engine 3.0”, understanding and utilizing entities has become a key strategy.

Query Processing and Information Retrieval

In the era of Google’s search engine 2.0, the sophistication of the underlying algorithms enabled an understanding of user intent behind a query, beyond just matching keywords. However, this model still had its limitations, as it was largely dependent on keywords, user search history, location and phrases within the text of indexed webpages.

• Example: The context of “Elvis” could mean Elvis Presley, Elvis Costello, or even a local restaurant named “Elvis”. The challenge was that it largely relied on the user to specify and refine their query, and was still limited by the semantics of the keywords.

Query Processing Improvements in 3.0

In the 3.0 model, entities refer to distinct and unique concepts or things, whether they are people, places, or objects. Using our earlier example, “Elvis” is no longer simply a keyword, but recognized as an entity, likely referring to the famous musician Elvis Presley.

• Example: When an entity like “Elvis Presley” is identified, the search engine can now associate a wealth of attributes with this entity, including aspects such as his music, his filmography, and his birth and death dates.

Query Processing and Topic Boundaries in Search Engine 3.0

In the “search engine 2.0” era, it was advantageous to create a separate page for each identified keyword, so that the page could be optimized for that term specifically. However, in “search engine 3.0”, the boundaries have become more fluid and are updated in real-time based on machine learning predictions and observed user behavior.

• Example: One website might aim to cover all there is to know about crayons in general – their history, types, manufacturing process, usage tips, etc. This website aims to become a topical authority on ‘crayons’ as a whole. On the other hand, another website might focus solely on red crayons – their unique pigments, popularity statistics, cultural significance, and so forth. This site is trying to establish its topical authority in a narrower context, but still a valid one.

SEO Applications and Takeaways

In the era of “search engine 3.0”, the game has changed. It’s not about whether the exact search term appears on the page. Google will now search for relative entities on your page, and attempt to link these entities to related entities throughout your entire site.

• Example: More comprehensive content wins. Centralize your backlink efforts on these broad, in-depth pieces instead of splitting topics across multiple narrow-focused articles. Use current SERPs as a starting point to identify important topics, but don’t be confined by them. Aim to go beyond the existing topical coverage in SERPs and provide valuable, comprehensive content to the user.

Scoring and Ranking the Documents

Once a search engine like Google has fetched potentially relevant documents, the next crucial step is to score these pages and rank them for a user to select. The evolution of artificial intelligence (AI) and natural language processing (NLP) has significantly transformed the way documents are ranked, marking a clear distinction between the 2.0 and 3.0 eras.

• Example: In the 2.0 era, Google’s scoring system was primarily driven by algorithms like PageRank, Hummingbird, Panda, and Penguin. These algorithms relied heavily on keyword matching and the number of backlinks to rank documents. In the “search engine 3.0” landscape, Google’s approach to scoring and ranking documents has evolved significantly. Google assesses a page’s suitability for a search query based on several key factors, including factual accuracy and user interaction signals.

Crawling and Indexing

Google’s web crawling and indexing techniques have evolved with its focus on entities. Understanding these changes is crucial as they directly impact how you should structure your website and formulate your content strategy.

• Example: In the “search engine 2.0” era, Google’s web crawlers, also known as spiders, systematically browsed the internet to discover new and updated pages. In the “search engine 3.0” era, Google’s crawlers are also trying to understand the entities that the keywords on a page represent. For example, a page about “Elvis” might also be indexed under related entities like “rock and roll music,” “Graceland” and “Blue Suede Shoes.”

Limitations and Constraints of Topical Authority

While we want to focus on building topical authority across any site we create, there are still some limitations. These limitations are lingering ranking factors from the Web 2.0 days to which Google still grants a reasonableamount of weight. These include factors like domain age, backlink profile, and user interaction signals.

• Example: A new website with comprehensive and high-quality content about “Elvis Presley” might still struggle to outrank older, more established websites. This is due to the weight Google places on the age of a domain and the quantity and quality of its backlinks.

Conclusion

The shift from “search engine 2.0” to “search engine 3.0” has brought about significant changes in the world of SEO. The introduction of entities has transformed the way search engines understand and process queries, and how they rank and present results. As SEO professionals, it’s crucial to understand these changes and adapt our strategies accordingly. By focusing on entities and building topical authority, we can create more effective SEO strategies that align with the evolving landscape of search engine technology.

• Example: An SEO professional who understands the importance of entities might focus on creating comprehensive content about a specific entity, such as “Elvis Presley,” rather than creating separate pages for each keyword related to Elvis. This approach aligns with the “search engine 3.0” model and can lead to better search rankings.

In conclusion, the world of SEO is constantly evolving, and it’s crucial for professionals in the field to keep up with these changes. By understanding the shift from “search engine 2.0” to “search engine 3.0” and the role of entities in modern SEO, we can create more effective strategies that align with the current landscape of search engine technology.
