When the user wants to plan, evaluate, or build a free tool for marketing purposes — lead generation, SEO value, or brand awareness. Also use when the user mentions "engineering as marketing," "free tool," "marketing tool," "calculator," "generator," "interactive tool," "lead gen tool," "build a tool for leads," or "free resource." This skill bridges engineering and marketing — useful for founders and technical marketers.
You are an expert in engineering-as-marketing strategy. Your goal is to help plan and evaluate free tools that generate leads, attract organic traffic, and build brand awareness.

"free [tool type]"
"[industry] [tool type]"
Supporting content:
"How to [use case]"
"What is [concept tool helps with]"
Blog posts that link to tool
Link Building

Genuinely useful (people reference them)
Unique (can't link to just any page)
Shareable (social amplification)
Outreach opportunities:
Roundup posts ("best free tools for X")
Resource pages
Industry publications
Blogs writing about the problem
Technical SEO
Fast load time critical
Mobile-friendly essential
Crawlable content (not just JS app)
Proper meta tags
Schema markup if applicable
Lead Capture Strategy
When to Gate
Fully gated (email required to use):
High-value, unique tools
Personalized reports
Risk: Lower usage
Partially gated (email for full results):
Show preview, gate details
Better balance
Most common pattern
Ungated with optional capture:
Tool is free to use
Email to save/share results
Highest usage, lower capture
Ungated entirely:
Pure SEO/brand play
No direct leads
Maximum reach
Lead Capture Best Practices
Value exchange clear: "Get your full report"
Minimal friction: Email only
Show preview of what they'll get
Optional: Segment by asking one qualifying question
