What Is Google SGE?

Google Search Generative Experience (SGE) is a new approach to search results in Digital Marketing. 

Google SGE in Digital Marketing is an experimental search experience that uses generative artificial intelligence (AI) to provide users with quick and clear overviews of search topics—without having to click on individual webpages.

This can help with a variety of tasks, such as:

• Finding answers
• Discovering topic overviews
• Summarizing key takeaways
• Getting how-to instructions

Let’s say you’re searching for what to do on a rainy day with elementary school kids. Previously, Google directed you to sites with ideas for activities. With SGE, Google gives you a list of suggestions at the top of the results compiled from multiple sources.

The rapid improvements in Google’s Search Generative Experience (SGE) and Sundar Pichai’s recent proclamations about its future suggest it’s here to stay.

The dramatic change in how information is considered and surfaced threatens how the search channel (both paid and organic) performs and all businesses that monetize their content. This is a discussion of the nature of that threat.

While writing “The Science of SEO,” I’ve continued to dig deep into the technology behind search. The overlap between generative AI and modern information retrieval is a circle, not a Venn diagram.

The advancements in natural language processing (NLP) that started with improving search have given us Transformer-based large language models (LLMs). LLMs have allowed us to extrapolate content in response to queries based on data from search results.

Let’s talk about how it all works and where the SEO skillset evolves to account for it.

What is retrieval-augmented generation?

Retrieval-augmented generation (RAG) is a paradigm wherein relevant documents or data points are collected based on a query or prompt and appended as a few-shot prompt to fine-tune the response from the language model.

It’s a mechanism by which a language model can be “grounded” in facts or learn from existing content to produce a more relevant output with a lower likelihood of hallucination.

While the market thinks Microsoft introduced this innovation with the new Bing, the Facebook AI Research team first published the concept in May 2020 in the paper “Retrieval-Augmented Generation for Knowledge-Intensive NLP Tasks,” presented at the NeurIPS conference. However, Neeva was the first to implement this in a major public search engine by having it power its impressive and highly specific featured snippets.

This paradigm is game-changing because, although LLMs can memorize facts, they are “information-locked” based on their training data. For example, ChatGPT’s information has historically been limited to a September 2021 information cutoff.

The RAG model allows new information to be considered to improve the output. This is what you’re doing when using the Bing Search functionality or live crawling in a ChatGPT plugin like AIPRM.

This paradigm is also the best approach to using LLMs to generate stronger content output. I expect more will follow what we’re doing at my agency when they generate content for their clients as the knowledge of the approach becomes more commonplace.

How does RAG work?

Imagine that you are a student who is writing a research paper. You have already read many books and articles on your topic, so you have the context to broadly discuss the subject matter, but you still need to look up some specific information to support your arguments.

You can use RAG like a research assistant: you can give it a prompt, and it will retrieve the most relevant information from its knowledge base. You can then use this information to create more specific, stylistically accurate, and less bland output. LLMs allow computers to return broad responses based on probabilities. RAG allows that response to be more precise and cite its sources.
