DIRECT ANSWERS

Clear answers for informed decisions.

SEO

What is SEO?

Search engine optimization improves how a website can be crawled, indexed, understood and matched to relevant searches. It combines technical foundations, useful content, internal links, metadata and authority signals. SEO can improve eligibility and discoverability, but it cannot guarantee a particular ranking, traffic level or number of enquiries.

AEO

What is AEO?

Answer engine optimization structures clear, accurate answers so search and assistant systems can extract useful information from a page. It uses direct responses, descriptive headings, accessible tables, supporting detail and visible FAQs. AEO depends on crawlable content and should help people first, rather than existing only as hidden schema.

GEO

What is GEO?

Generative engine optimization improves the clarity, evidence and entity consistency of content that may be retrieved or cited by AI-generated answers. It emphasizes unambiguous facts, first-party evidence, corroboration, current information and source relationships. GEO builds on SEO; it is not a replacement for crawlability, indexing or useful content.

Comparison

Does GEO replace traditional SEO?

No. AI-connected search systems still depend on discoverable, indexable and trustworthy web content. Google states that its established SEO best practices remain relevant to AI Overviews and AI Mode. GEO adds evidence and citation readiness, while AEO improves answer clarity; both rely on a sound SEO foundation.

01

How the three systems work together

A practical sequence starts with technical access, then adds useful answers and evidence.

  • SEO establishes the canonical, crawlable and indexable page.
  • AEO makes the page answer specific questions directly.
  • GEO connects claims to stable entities, current facts and verifiable evidence.
  • Internal links help crawlers and readers move between the guide, service, product and proof pages.
02

Technical, content and authority requirements

No special markup can compensate for weak or inaccessible content.

  • Technical: successful HTTP responses, canonical URLs, robots access, sitemaps and mobile-safe rendering.
  • Content: one clear intent, direct explanations, useful depth and no keyword-swapped duplicates.
  • Authority: stable company identity, genuine products, public projects, dated updates and external corroboration where available.
  • Structured data: page-matched entities and relationships, never unsupported ratings, reviews or claims.
03

How to measure progress

Measurement should separate eligibility, discovery and business outcomes.

  • Confirm crawling, indexing and canonical selection.
  • Review impressions, clicks, landing pages and qualified enquiry paths.
  • Record AI citations and referral traffic where tools expose them, without treating a citation as a ranking.
  • Review factual accuracy and update pages when products, prices or availability change.

The three disciplines overlap, but each has a distinct primary job.

FREQUENTLY ASKED QUESTIONS

Important details before you decide.

Can AI-search visibility be guaranteed?
No. A site can improve crawlability, answer clarity, entity consistency and evidence, but search and AI systems decide what to crawl, index, rank or cite. Google and OpenAI both state that eligibility does not guarantee placement. Any responsible service should report work completed and observed results without promising inclusion.
How can a company appear in AI search?
Publish crawlable, indexable pages with a clear entity identity, direct answers, genuine evidence and useful internal links. Keep facts current, allow the relevant search crawler where appropriate, and build external corroboration. These steps improve eligibility and understanding; they do not guarantee that a system will select the page.
