Search-term patterns in industrial laser marking hide real buyer intent under layers of contamination. A raw search-term report shows 'laser marker', 'laser engraver', 'laser marking machine' side by side with 'DIY laser engraver kit', 'laser engraver etsy', and 'fiber laser hobby' — all landing in the same bucket. Signal extracts bigrams and trigrams from your search-term list and runs statistical significance testing on conversion data, surfacing patterns that actually convert (e.g., 'fiber laser' + 'industrial' or 'laser marker' + 'production line') vs. patterns that are pure contamination (laser + hobby, laser + DIY). For laser-marking accounts, the highest-leverage move is running Signal on your bottom-quartile keywords (lowest conversion rate, moderate volume) to surface the combinations that are dragging down your conversion rate. Common finding: 'laser marker' + 'home' or 'small business' clusters at 0.8% conversion, while 'laser marker' + 'production' clusters at 8%. Use Signal to isolate these patterns, build them out as phrase-match keywords with Forge, and split them into separate ad groups with compliance-focused copy. Run Signal monthly; contamination patterns shift as Smart Bidding finds new cheap-click pools.
