## Short answer

Use the AI crawler checker to see if ChatGPT, Perplexity, Claude, Google and Bing may read your website. Use the missed call calculator to see what unanswered calls cost you a year. Use the lifetime value calculator to see what one customer is worth, and so what you can afford to spend to win one.

## [AI crawler checker](/tools/ai-crawler-checker/)

  
Type your website. See which of 12 search and AI crawlers your robots.txt lets in, whether a firewall blocks them, and whether you have schema and an llms.txt file.

  
## [Missed call cost calculator](/tools/missed-call-calculator/)

  
Four numbers in: calls per week, share missed, booking rate, average job. Out: what missed calls cost you each month and year.

  
## [Customer lifetime value calculator](/tools/hvac-customer-lifetime-value-calculator/)

  
Service calls, maintenance plan, install chance and margin. Out: the lifetime revenue and profit of one customer.

  
## The one that is not instant: the 7-gap report

  
We ask the AI assistants the questions your buyers ask, check your Google and Maps position next to the companies above you, and send at least 7 named gaps with the fix for each. Free, inside 48 hours. [Request it here](/audit/).
