10- Cutlery
Cutlery is a practical Python script designed for copywriters and content creators to analyze competing web content and uncover keyword overlaps. By processing URLs listed in input.txt, it extracts valuable insights, such as shared keywords, phrases, and topics, directly from high-quality content sources. The results are neatly compiled into an output.csv file for easy review.
The tool allows customization through the garbage.txt file, where you can specify keywords to filter out. It's built for simplicity: install dependencies using pip, run the script, and open the generated CSV file. While primarily tested on Linux, it should work on Windows and macOS too.
Keep in mind that long-tail keyword results (like trigrams and bigrams) may occasionally miss common stop words like "if" or "to," leading to slightly odd phrasings, however these are usually easy to spot and correct manually.
Importantly, Cutlery isn't meant to replace strategic SEO thinking; rather, it serves as a creative aid by highlighting successful content patterns from top-performing pages. This helps writers craft more informed, targeted, and effective content.
