NotebookLM for Content Research (with SEO Focus)
This repository contains insights and artifacts generated by Google NotebookLM from a single video NotebookLM just Made SEO Research Faster than Ever by Grace Leung. A huge thank you to Grace for sharing valuable strategies to: (1) use NotebookLM, and (2) enhance content research processes, beyond SEO!
Overview
NotebookLM is a versatile and powerful tool designed to streamline and enhance the content research process. While the examples here have an SEO focus, the techniques apply to any research-intensive content creation scenario—from academic research to journalism and technical documentation.
A key feature enabling many of these use cases is Discover Source, a built-in web search function that scans online sources based on a topic description and returns relevant results for easy import. This feature is partly powered by Google’s algorithm and tends to return authoritative and trustable sources, often pages that already rank on Google. Discover Source also understands search operators like site:
, filetype:
, and day range operators for more granular control over the search results. Being specific in the topic description and specifying source types or asking for diverse sources can yield better results.
Particularly valuable is NotebookLM’s ability to directly extract and process YouTube transcripts with minimal hallucination, saving hours of manual work for researchers, content creators, and students.
Mind Maps
NotebookLM generated mind maps work wonders during the research phase, but you can only export the current view as static image. E.g. the mind map below is generated when I expanded SEO Use Cases
node:

To create a comprehensive and interactive mind map, the following steps were taken:
-
Prompt NotebookLM with:
Create a mind map from the sources. List topics as central ideas, main branches, and sub-branches. Output it in Markdown format.
-
This generated the Markdown that was pasted into a file called Markmap Mind Map.md.
-
and the Markdown was then processed using a tool like Markmap (or the Markmap VS Code extension) to convert the Markdown into an interactive HTML
file, or SVG
file.

This approach allows for a complete, shareable, and interactive visualization of the research topics.
SEO Research Use Cases
While Grace’s video focuses on SEO applications, these techniques can be adapted for any content research scenario. The mind maps above visualize how these approaches interconnect to form a comprehensive research methodology.
Here are the primary use cases uncovered from the source YouTube video:
1. Competitor Content Gap Analysis
- Purpose: To quickly compare your content strategies against competitors and identify areas where your content may be lacking.
- How NotebookLM Helps: Speeds up the analysis by allowing import and AI comparison of competitor content.
- Process: Use Discover Source with operators like
site:
and day range filters to find and import specific competitor blog articles. Import your own article. Use a prompt to ask NotebookLM to analyse the gaps, broken down by customer journey stages, target audience roles, and problems addressed.
- Output: A breakdown showing differences in strategies, which stages a competitor might be stronger in, audience/problem differences, and potential new content opportunities.
2. Generating Better FAQs for AI Search
- Purpose: To create more in-depth and specific FAQs, a content format favoured by AI search engines.
- How NotebookLM Helps: Combines NotebookLM’s capabilities with web search (Discover Source) and other imported data to generate richer FAQs than the built-in feature. Helps ensure Q&A is bite-sized, which is good for AI search.
- Process: Use Discover Source to find question-based content from forums like Reddit. Import these sources. Optionally, import your own research data (e.g., Ahrefs question lists, Search Console data) as copied text. Use a prompt to identify valuable questions and group them by search intent.
- Output: A list of relevant questions with answers, often grouped by search intent, described as much more in-depth and specific.
3. Getting Authority Signals in AI Search / EEAT
- Purpose: To understand what expertise, research, or other signals AI uses to trust and prioritise resources, helping improve your content’s EEAT (Experience, Expertise, Authoritativeness, Trustworthiness).
- How NotebookLM Helps: Extracts authority signals quickly from authoritative sources and top-ranked pages.
- Process: Use Discover Source to find web pages from authoritative sources on your topic. Import these. Separately, find the actual top-ranked pages on Google (e.g., using a Chrome plugin like SERP Snippet Extractor). Bulk import these URLs into NotebookLM using a tool like WebSync full site importer. Use prompts to list identified authority signals (author expertise, data, examples). Use a second prompt for more specific details like citation patterns, data points, and how signals are leveraged.
- Output: A list of authority signals and detailed insights into how top pages utilise them, guiding what to include in your own content.
4. Semantic Keyword Clustering
- Purpose: To understand the context and meanings around a topic to build content around key subtopics, improving topical authority for AI search.
- How NotebookLM Helps: Streamlines the process, provides quick ideas for semantic groups, and helps visualise topic hierarchy.
- Process: Use Discover Source to find diverse sources on a topic (e.g., blogs, guides, tutorials, case studies). Import them. Add more sources for comprehensive research. Generate a mind map within NotebookLM to visualise topic hierarchy and core subtopics. Use a prompt to create a semantic cluster showing primary/subtopics and associated semantic terms.
- Output: A visual mind map (downloadable), a text-based semantic cluster breakdown, and potentially a suggested topic pillar structure and related questions.
5. Keyword Gaps
- Purpose: To identify keywords and search intents present in top content but missing from your own article, enhancing content relevance and depth.
- How NotebookLM Helps: Uses its web search to find relevant content quickly and compares keywords/intents across sources.
- Process: Use Discover Source to find “top content” for a keyword (trustable sources). Also import the actual top-ranked pages using plugins. Use prompts to identify top keywords (including long-tail) across these sources. Import your own article. Use a prompt to compare your article against the imported sources and identify missing keywords and search intents.
- Output: Lists of important keywords from sources and specific keywords/search intents missing from your article. These suggestions should be reviewed carefully.
6. YouTube Content Research
- Purpose: To extract insights, data, and supporting information from YouTube videos as part of content research.
- How NotebookLM Helps: Features a handy YouTube video import function, allowing for extraction with minimal hallucination.
- Process: Use Discover Source to find relevant YouTube videos. Discover Source is particularly handy for facilitating bulk video uploads from YouTube.
- Output: Extracted insights, data points, and supporting information from video content.
- Purpose: To gather reliable insights, data claims, and supporting information from various sources.
- How NotebookLM Helps: Known for its minimal hallucination, reducing the chance of incorrect information compared to other tools.
- Process: Import sources into NotebookLM (often via Discover Source). Use NotebookLM’s capabilities to extract the key insights, data, and supporting details needed.
- Output: Reliable insights, data, and supporting details derived from your source material.
Beyond SEO Applications
While the examples in this repository have an SEO focus (based on Grace’s excellent tutorial), the same techniques apply broadly to:
- Academic Research: Literature reviews, thesis preparation, identifying research gaps
- Journalism: Story research, fact verification, source consolidation, video content extraction
- Technical Documentation: API documentation, user guides, technical comparisons, support resources
- Education: Curriculum development, lesson planning, creating learning materials, comprehensive topic coverage
- Business Intelligence: Market analysis, competitive research, trend identification, product comparisons
- Content Creation: Podcast preparation, script writing, book outlining
The combination of NotebookLM’s minimal hallucination tendency, source-based analysis, and YouTube transcript extraction capabilities makes it a powerful tool for any research-intensive content creation process.
These use cases demonstrate how NotebookLM, powered by features like Discover Source and combined with external tools, can significantly accelerate and improve the quality of your content research across multiple domains.
