Natural Language Processing (NLP)-based automation: Use Python with scikit-learn or spaCy to analyze website content (e.g., meta descriptions, titles) and categorize via text classification or topic modeling (e.g., LDA). Train with a small, manually labeled dataset to ensure accuracy.
Web Scraping + Rules: Use BeautifulSoup or Scrapy and apply rule-based classification (e.g., "health" in the URL → "health" category). Use pandas.
Insights API: Use Clearbit, SimilarWeb, or the Google Cloud Natural Language API to extract pre-existing categories or metadata to reduce manual work.
Clustering: Apply K-means or DBSCAN to group similar websites based on content or backlinks, then label clusters as categories.
Hybrid Workflow: Automate initial categorization, then use Airtable or Google Sheets for team review and refinement. Feedback corrections to improve the model.
SEO Tools: Export pre-categorized data from Moz, Ahrefs, or SEMrush to integrate into your database.
