SEO Considerations
Keyword Strategy
Tool landing page:
- "[thing] calculator"
- "[thing] generator"
- "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
Free tools attract links because:
- 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
Post-Capture
- Immediate email with results/link
- Nurture sequence relevant to tool topic
- Clear path to main product
- Don't spam—provide value
---
Build vs. Buy vs. Embed
Build Custom
When:
- Unique concept, nothing exists
- Core to brand/product
- High strategic value
- Have development capacity
Consider:
- Development time

- Bug fixes
Use No-Code Tools
Options:
- Outgrow, Involve.me (calculators/quizzes)
- Typeform, Tally (forms/quizzes)
- Notion, Coda (databases)
- Bubble, Webflow (apps)
When:
- Speed to market
- Limited dev resources
- Testing concept viability
Embed Existing
When:
- Something good already exists
- White-label options available
- Not core differentiator
Consider:
- Branding limitations
- Dependency on third party
