One of the more grey hat things I have been looking at is extracting keyword data from Facebook Groups.
The basic process is as follows:
- Scrape all of the post titels from a relevant Facebook group
- Export all of the posts to an Excel file
- Do topic clustering
By doing this, you are able to get a pretty decent amount of nice, natural-language queries.
The trick here is using an AI-based scraper that will get the job done in a storm.
