Keyword and Ad Extension Generators: What Actually Helps

Keywords control who sees the ad and extensions control how much of the results page it occupies. A useful keyword generator separates intent instead of dumping volume, gives match type guidance, and produces negatives alongside the keyword list. A useful extension generator respects the tighter limits — sitelink link text 25 characters with two 35-character description lines, callouts 25 characters, structured snippet values 25 characters — and points only at pages that exist. Validate search volume in Keyword Planner; generators are for coverage and structure, not measurement.
