Anyone can write llms.txt. Few teams ship the whole standard.
Everything Grow ships is technically free — semantic HTML, JSON-LD, llms.txt, robots.txt, edge caching. The cost isn't the code, it's the 30+ hours of engineering judgement to do it right and the 6+ weeks of revision cycles to find out you didn't.
If you have a senior engineer with GEO experience and a free week, build it yourself. Most teams have neither, ship a half-finished version, score 65/100, and convince themselves AI traffic isn't a real channel. Grow is the shortcut: a 100/100 site delivered against a published standard.
Grow is best for: Teams whose eng leads can't justify a quarter of internal time to relearn what we've already shipped 50+ times.
| Dimension | Grow | DIY (roll your own) |
|---|---|---|
| Total cost | $2,400–$4,800 fixed | 30–80 eng hours + opportunity cost |
| Time to live | 48 hours – 5 days | 2–8 weeks typical, with revisions |
| Standard followed | geo-standard@2026.05, published | Whatever your team decides |
| Verified score at delivery | 100/100 on /check or we fix it | Self-graded |
| Ownership of the code | You own it, host anywhere | You own it, host anywhere |
| Internal team learns the craft | Less hands-on learning | Deep learning by doing |
| Maintenance after launch | You maintain | You maintain |
Yes — the standard is public at geo-standard@2026.05 and the /check scanner is free. The gap is execution: most teams stall on edge caching, per-route JSON-LD shape, and the robots.txt bot matrix. If those three sentences sound trivial to you, build it yourself.
Compressed time, a published standard, and a verified score. The code is open — the judgement isn't.
48-hour delivery. Fixed price. Built semantic-first.
