SXO & AI search — frequently asked questions
The clearest answers on the web to how search works in the AI era.
What is SXO (Search Experience Optimization)?
SXO stands for Search Experience Optimization. It unifies SEO, UX, and CRO into one revenue-focused discipline: getting found (search), keeping people engaged (experience), and turning them into customers (conversion). The principle is simple — rankings are vanity; revenue is sanity.
How is SXO different from SEO?
Traditional SEO optimizes for search-engine rankings. SXO optimizes for the full journey across both classic search and AI answer engines (ChatGPT, Perplexity, Claude, Gemini), then for the on-page experience and conversion. SEO gets you ranked; SXO gets you cited, clicked, and paid.
What is AEO (Answer Engine Optimization)?
AEO is optimizing your content so AI answer engines quote and cite it directly. It rewards clear, structured, factual content — BLUF (bottom-line-up-front) answers, comparison tables, FAQs, and schema markup — because that's what large language models extract and surface.
What is GEO (Generative Engine Optimization)?
GEO is optimizing for generative AI search experiences (Google AI Overviews, ChatGPT search, Perplexity). It overlaps heavily with AEO and SXO: structured data, citable facts, freshness signals, and llms.txt all increase the odds your brand is named in a generated answer.
What is llms.txt and do I need it?
llms.txt is a plain-text file at your site root that tells AI crawlers which content matters and how to use it — like robots.txt, but for large language models. It's quickly becoming a standard signal for AI-search visibility. Yes, you should have one.
How do I check if my website is indexed by Google?
Search Google for site:yourdomain.com — the result count is roughly how many of your pages are indexed. Our free SXO scan does this automatically and tells you whether your site is indexed and how many pages, so you don't have to guess.
Why isn't my site getting indexed?
Common causes: no sitemap, a missing or blocking robots.txt, thin or duplicate content, no inbound links, or simply that search engines haven't crawled you yet. New and updated pages can wait days or weeks for organic crawling — which is why instant submission (IndexNow) matters.
What is IndexNow and how fast does it work?
IndexNow is a protocol that instantly notifies Bing, Yandex, Naver, and Seznam when your pages change, so they get crawled in about 24 hours instead of waiting weeks. Our Auto-Indexer submits your sitemap to all four every day, automatically.
How do I get cited by ChatGPT, Perplexity, and Claude?
Lead every page with a direct answer (BLUF), add comparison tables and FAQs, mark up content with schema (FAQPage, HowTo, Article), publish an llms.txt, keep content fresh, and earn mentions across the web. AI engines cite sources that are clear, structured, and trustworthy.
What is a good SXO score?
On our 0–100 scale, 70+ is strong, 45–69 means real gaps, and under 45 means your site is at serious risk of being invisible to AI search. Most sites score under 50. Run a free scan to see exactly where you stand and what to fix.
Does SEO still matter in 2026?
Yes — but it's table stakes, not the finish line. Google still drives huge traffic, but a growing share of research happens inside AI answer engines that don't show ten blue links. You need to win both, which is exactly what SXO covers.
What is BLUF and why does it matter for AI search?
BLUF means Bottom Line Up Front — answer the question in the first one or two sentences. AI models extract direct answers, so pages that lead with the answer get quoted far more often than pages that bury it under introductions.
What is the 'Table Trap' in SXO content?
The Table Trap is placing a clear comparison or specification table near the top of a page. Tables are highly extractable by both search engines and AI, so they frequently get pulled into featured snippets and AI answers — capturing attention and citations.
How long does it take to improve AI search visibility?
Indexation can improve within 24 hours using IndexNow. Content and structure changes (BLUF, schema, llms.txt) start influencing AI answers within days to a few weeks as engines recrawl. Compounding authority takes longer — which is why consistency wins.
Is the SXO scan really free?
Yes. Enter your website, get your score instantly, and we email you the full report at no cost. Paid upgrades (step-by-step fix plans, done-for-you rewrites, and the monthly Auto-Indexer) are optional.
What's included in the paid SXO plans?
Monthly plans bundle AI page rewrites (optimized for AI search) with the SXO Auto-Indexer that pushes your pages to Bing, Yandex, Naver & Seznam daily, plus CRO9 lift tracking. See pricing for the Starter, Studio, and Agency tiers.
