AI search optimization is the practice of getting your business cited across AI answer engines: ChatGPT, Gemini, Perplexity, Claude, and Google AI Overviews. It overlaps with generative engine optimization (GEO), answer engine optimization (AEO), and LLMO. This post defines each term and gives six tactics you can act on this week.
AI search optimization in five points
One r/smallbusiness commenter put it: "What used to move the needle quickly doesn't do as much now."
- AI search optimization means getting your business named in AI-generated answers, not just ranked.
- AI engines extract passage-level answers, so your content must be written in clear, direct chunks.
- The key surfaces: Google AI Overviews, ChatGPT, Gemini, Perplexity, and Claude.
- Traditional SEO foundations still apply; AI search optimization layers new requirements on top.
AI search optimization, AI SEO, GEO, AEO, and LLMO: definitions
One owner on r/smallbusiness put it: "AEO is a thing as well. Try researching on it." These terms all describe the same underlying discipline. Use the definitions below to know which surface each term refers to.
AI search optimization
The broadest term. Optimizing your online presence so AI-powered search engines surface your business when a user asks a relevant question.
AI SEO
Used interchangeably with AI search optimization by most agencies. Emphasizes continuity with traditional SEO while naming the AI layer on top.
GEO
Generative engine optimization. The academic term for optimizing content so generative AI systems extract and cite it from your pages.
AEO
Answer engine optimization. Rewrites prose into direct question-and-answer structures that AI engines can lift verbatim, similar to featured snippets.
LLMO
Large language model optimization. Focuses on the retrieval signals large language models use to decide whether to cite a source.
AIO
AI Overview optimization. Google-specific. Targets the AI Overview panel that appears above organic results on relevant searches.
How AI search optimization works
Spearleaf's AI search optimization service is built on core mechanics that explain why AI search differs from traditional keyword work. Google's guidance on optimizing for generative AI features names two of them; the rest are widely documented in AI search research.
-
Retrieval-augmented generation (RAG). The AI retrieves documents from the web in real time. Your page must be crawlable and indexed to enter the retrieval pool. (Google-named mechanic.)
-
Query fan-out. The AI breaks a question into sub-queries and retrieves sources for each. A page answering one narrow question clearly gets retrieved for that sub-query. (Google-named mechanic.)
-
Passage-level extraction. The AI reads at the paragraph level, not the page level. Short, direct paragraphs that answer one question are more extractable.
-
Citation selection. The engine selects which sources to cite. E-E-A-T signals, entity clarity, brand mentions, and structured data all influence whether your domain gets named.
-
Nondeterministic output. AI responses vary by query run. That makes AI search optimization an ongoing discipline, not a one-time fix.
AI SEO versus traditional SEO: the expanded program
Rank position now shares importance with AI visibility across citation sources. Check the two columns below to see what an expanded program requires.
What stays the same
Technical SEO foundations, Core Web Vitals, E-E-A-T signals, internal linking, GBP completeness, review count, and schema markup all still apply.
What AI SEO adds
Entity clarity, passage-level writing, off-page brand mentions, semantic search alignment, content freshness (a rough 12-month window), and question-based content for conversational AI queries. Spearleaf's AI search optimization service covers both layers from week one.
Six tactics for AI search optimization you can start this week
These are the 6 tactic families every top-ranked source names, applied to local and mid-market service businesses.
-
Write in direct question-and-answer blocks. Each H2 should answer one question in the first 2-3 sentences. Clear opening answers are the most extractable units on a page.
-
Add FAQ schema to your service pages. Schema markup signals structure to both AI systems and search engines. Use Schema.org FAQ markup on pages where you answer common objections.
-
Request brand mentions, not just backlinks. Get your name into directories, niche press, and local chamber profiles. Unlinked mentions build the entity signal AI engines use to identify you.
-
Build and maintain your Google Business Profile. Reviews, categories, and Q&A feed directly into Google AI Overviews for local queries. This is the single highest-return asset for a local service business.
-
Refresh your top pages every 6-12 months. AI engines weight recently updated content from authoritative sources. For a deeper look at local AI signals, see how AI is changing local search.
-
Audit technical SEO basics first. A slow or unindexed page cannot enter the retrieval pool. Run a Lighthouse audit and fix Core Web Vitals issues before optimizing content.
AI search optimization for local service businesses
If you run a plumbing company, med spa, or law firm, the AI search shift hits you differently than a SaaS brand. Most major guides on this topic write for national brands, not local service businesses. Start with your Google Business Profile; it is the fastest path to local AI visibility.
Your GBP is your most important AI citation asset. Google AI Overviews for local queries pull from your Knowledge Panel, review profile, and Q&A section. A complete, well-reviewed GBP is the fastest path to appearing in local AI answers.
Off-page brand mentions from local press, chamber listings, and niche aggregators build the entity signal AI engines use to confidently name you. A focused local strategy outperforms a broad national keyword campaign. Read the full breakdown at AI search optimization for Fort Myers businesses.
Why this is not just relabelled SEO (the Spearleaf proof point)
We track 5 AI surfaces with monthly spot-check prompts; ask any agency to name those surfaces and what they measure. One r/smallbusiness commenter summed it up. "There are a ton of bargain 'SEO gurus' out there who take money for a few months and nothing happens."
Traditional SEO optimizes for a rank position. AI search optimization optimizes for being named in a synthesized answer. Different outputs require different inputs: entity clarity, extractable passage structure, off-page brand mentions, and freshness maintenance.
Joshua Albanese, the founder, has been building businesses from zero using organic marketing since 2007. His brands have generated $20M+ in cumulative revenue (representative) with $0 in ad spend. He relaunched a Fort Myers headshot brand in July 2025 that ranked first locally in about 14 days. Personal track record on his own brands; individual results vary.
Frequently asked questions
Is AI search optimization just another SEO buzzword agencies use to relabel old work?
AI search optimization adds a real new layer to traditional SEO: entity clarity, passage-level answer structure, off-page brand mentions, schema markup, and freshness. The output is different too. Traditional SEO targets a rank position; AI search targets a citation in a synthesized answer. Ask any agency whether they optimize for Google AI Overviews, ChatGPT, Gemini, Perplexity, and Claude specifically.
Can I do AI search optimization myself with ChatGPT for free?
You can start. Answer-first writing, FAQ schema, and GBP completeness are implementable without an agency. ChatGPT is one of the surfaces you want to appear in, not a tool to optimize them. The challenge with DIY is monitoring: AI responses are nondeterministic, so you need repeated prompts across engines to get a reliable citation read.
Is AI search optimization the same as AEO, GEO, AIO, or LLMO?
Yes, they overlap. AI search optimization is the broadest term. GEO is the academic name. AEO focuses on extractable answer structure. LLMO focuses on large language model retrieval signals. AIO is Google-specific. One r/smallbusiness commenter put it: "AEO is a thing as well. Try researching on it." All describe the same underlying discipline.
How will I know AI search optimization is actually working?
Track GBP impressions, calls, and direction requests weekly. Run manual prompts on ChatGPT, Gemini, Perplexity, and Claude for your key service queries monthly. Track brand mention volume via Google Alerts. Demand a monthly report that shows GBP performance and AI spot-check results, not just impressions and clicks.
Are backlinks dead in AI search?
No. A take circulates on r/smallbusiness: "Backlinks are becoming irrelevant and mentions are becoming relevant." The first half is overstated; the second half is directionally correct. Links still matter for traditional rankings, which feed the retrieval pool AI engines draw from. Unlinked brand mentions and entity signals have grown in relative weight. Build both.
Does traditional SEO still work, or has AI search optimization replaced it?
Traditional SEO is the foundation. Without crawlability and E-E-A-T signals, a page cannot enter the retrieval pool AI engines draw from. AI search optimization layers on top, adding entity clarity, passage-level writing, and brand mentions. One r/smallbusiness owner put it. "What worked better for me was finding a local SEO guy who specializes in small businesses, not one of these big agencies that charge thousands."
