Search, AI and authority, answered

Authority Signals is an independent industry publication covering SEO, answer engine optimization, generative engine optimization, local search and the authority signals that drive visibility in both search engines and AI assistants. It is produced in partnership by Haller It Digital Marketing and Luminous Create, and every article is bylined to the strategist who wrote it.

Authority signals are the cues that tell search engines and AI systems your brand is a credible, expert source on a topic. They include entity clarity, topical depth, links and unlinked brand mentions, brand search demand, consistent information across the web, and demonstrable experience and expertise. No single signal is decisive. Authority emerges when they converge. See our full guide to authority signals.

SEO, search engine optimization, is about ranking in search results. AEO, answer engine optimization, is about being served as the direct answer, in a snippet, a voice result or an AI summary. GEO, generative engine optimization, is about being the cited source inside AI generated responses from systems like ChatGPT, Gemini, Perplexity and Google AI Overviews. They share most fundamentals but optimize for different surfaces. Our GEO playbook covers the detail.

Make your content easy to verify and easy to reuse, and build corroboration across the web. Lead with direct answers, support them with specific data and cited sources, use structured data and clean headings, state your entity facts clearly, and earn third party mentions and reviews. Peer reviewed research found that adding statistics, quotations and citations can lift AI visibility by up to about 40 percent, and AI systems consistently favor brands corroborated across many independent sources over self reported claims.

Yes. The work is broadening, not ending. Clicks from ranked links are declining as AI answers expand, but the fundamentals, technical health, quality content and authority, are exactly what get a brand cited inside AI answers. The objective shifts from ranking in a list to being the trusted source an answer is built from.

The publication itself is editorial, but its founding partners offer services. Haller It Digital Marketing, founded by Kristin Crawford, provides SEO first websites, generative engine optimization and local SEO for service businesses. Luminous Create, founded by Laura Ludwin, focuses on AI search visibility and structural SEO for high value service industries. Reach either through our contact page.

Authority Signals is partnership funded and editorially independent. Some outbound tool links, including Search Atlas, are partnership links. If you start a subscription through them, a portion of the proceeds helps fund ongoing research here. This never affects our coverage or the price you pay, and we disclose these links wherever they appear.
