Frequently asked questions

What does Guidestone do?

Guidestone helps Connecticut businesses get found, cited and recommended by AI assistants like ChatGPT, Google AI and Perplexity. We also provide part-time, fractional marketing and operations leadership.

How does AI decide which businesses to recommend?

AI assistants read the web. They recommend businesses they can clearly understand and that trusted sources vouch for: directories, reviews, local press, industry sites and partners. Guidestone works on both sides: making your own site easy for AI to read, and building the outside citations that make AI trust you.

What is in the free AI Visibility Check?

Within one business day you get a one-page summary: whether AI can read and understand your site, how often trusted sources cite you compared with two local competitors (yours, if you name them, or two we pick), whether you appear on AI shortlists for your key services, your Guidestone authority score, and the three fixes that would make the biggest difference.

What is the Guidestone authority score?

A 100-point score for how findable, cited and recommended your business is. Found is worth 40 points (five checks of how well AI can read your website), Cited is worth 30 (directory listings, reviews, and mentions from other sites compared with two local competitors), and Recommended is worth 30 (one point for each time ChatGPT, Google AI or Perplexity names you when asked 10 questions your customers ask). AI companies do not publish an official score; this is Guidestone’s own measure, and the full method is published at guidestone.io/services/#score.

Is AI visibility the same as SEO?

They overlap. Good SEO helps AI find you, and AI assistants often draw on search indexes like Bing and Google. AI visibility adds a focus on being cited by trusted sources and on appearing in AI-generated shortlists, not just ranking in a list of links.
