You are an expert SEO strategist and software product manager with a deep understanding of keyword research and natural language processing. You are tasked with defining the specifications for a new "Keyword Clustering Tool" that will help SEO professionals and content marketers efficiently group related keywords for content planning and website optimization. Your goal is to create a detailed feature specification document that will guide the development team. This tool will need to work with large amounts of keyword data pulled from various sources. Define the following key aspects of the Keyword Clustering Tool: I. Core Functionality: A. Keyword Input & Sources: 1. Describe the methods for inputting keywords into the tool. (e.g., manual entry, CSV upload, API integration with [Keyword Research Tool Name]) 2. Specify the acceptable format for keyword lists (e.g., one keyword per line, comma-separated values). 3. Explain how the tool should handle duplicate keywords and special characters. B. Clustering Algorithm: 1. Detail the algorithm(s) to be used for keyword clustering. (e.g., Hierarchical clustering, K-means clustering, NLP-based semantic similarity analysis) 2. Explain how the algorithm determines the similarity between keywords. (e.g., based on search engine results page overlap, semantic meaning, user intent) 3. Describe how the number of clusters is determined (e.g., user-defined, automatically optimized based on data characteristics). C. Cluster Analysis & Refinement: 1. Explain how the tool presents the generated clusters to the user. (e.g., interactive visualization, tabular format) 2. Describe the options for manually refining the clusters. (e.g., merging, splitting, moving keywords between clusters) 3. Specify how the tool provides insights into each cluster. (e.g., average search volume, keyword difficulty, related questions) D. Output & Export: 1. Describe the available options for exporting the clustered keyword data. (e.g., CSV, XLSX, Google Sheets integration) 2. Specify the data fields included in the export. (e.g., cluster name, keywords, search volume, keyword difficulty) 3. Explain how the tool can be used to generate content ideas based on the clusters. II. User Interface (UI) and User Experience (UX): A. Describe the overall layout and design of the tool's interface. Consider ease of navigation and visual clarity. B. Specify how the tool provides feedback to the user during the clustering process. (e.g., progress indicators, error messages) C. Outline the key user interactions and workflows. (e.g., importing keywords, running the clustering algorithm, refining clusters, exporting data) III. Advanced Features (Optional): A. Competitor Analysis: Explain how the tool could integrate competitor data to identify keyword opportunities. B. Intent Analysis: Describe how the tool could automatically classify the search intent behind each keyword (e.g., informational, navigational, transactional). C. SERP Feature Analysis: Specify how the tool could analyze the search engine results pages (SERPs) for each keyword to identify relevant SERP features (e.g., featured snippets, image packs, video carousels). IV. Performance & Scalability: A. Specify the expected performance of the tool in terms of processing time for different sizes of keyword lists. (e.g., less than 1 minute for 1,000 keywords) B. Outline the scalability requirements of the tool to handle large volumes of data and concurrent users. V. Example Use Case: Provide a detailed example of how a user would use the Keyword Clustering Tool to plan a content strategy for a website in the [Industry] industry. Output Format (Use plain text, not markdown): Structure your response into sections corresponding to the points above (I, II, III, IV, V). Within each section, use sub-sections (A, B, C, etc.) to provide detailed specifications. Be as specific and concrete as possible. Avoid vague statements. Tone and Style: - The tone should be professional, technical, and informative. - The language should be clear, concise, and easy to understand for developers.
