How many types of SEO are there really?

One discipline, many contexts. The list above covers every name in common use, and for a typical small business three or four are genuinely relevant. Anyone selling you all of them is selling invoices.

Which type should a new business start with?

Technical first, because it determines whether anything else is visible. Then on-page for the pages that sell. Then content, which is the part that compounds and the part everyone skips.

Is GEO replacing SEO?

No. It shares the same foundations and adds a new consumer. A site that is crawlable, server-rendered, structured and corroborated does well in both. A site that fails those fundamentals fails in both.

Is black-hat SEO ever worth it?

Not for a business that intends to exist next year. The tactics work until they are detected, and detection removes the asset rather than the gain. Every recovery I have seen cost more than the shortcut saved.

Pillar guide

The 35 types of SEO, explained without the padding

Most "types of SEO" are not separate disciplines — they are the same fundamentals applied to a different context: a place, a business model, a content format or an engine. Three or four will apply to any given site. Buying all of them is how agencies bill for work that does nothing.

Why there are so many names

SEO has one mechanism — be findable, be understandable, be preferable — and a large number of contexts. Each context gets a name, and the names accumulate faster than the discipline changes. That is not entirely marketing: a local plumber and a global SaaS genuinely need different work. But the shared foundation is much larger than the differences, and a vendor selling you eleven "types" is usually selling one job eleven times.

Below is every type in common use, grouped, with a straight answer on what it means and when it matters.

Geographic and location-based

Local SEO: Ranking for searches with local intent, and appearing in map results. Driven by business listings, consistent name/address/phone, reviews and location-relevant content. Essential if customers come to you or you travel to them.
Hyperlocal SEO: Local SEO narrowed to a neighbourhood or a few streets. Only meaningful in dense cities where "near me" genuinely differs block to block.
National SEO: Competing across one country without a local advantage. Harder than local, because you compete with everyone rather than with whoever is nearby.
Global / international SEO: Multiple countries, typically multiple languages. Adds domain structure, hreflang and localised commercial terms to the usual work.
Multilingual SEO: The same content in more than one language. A permanent maintenance obligation, not a translation project — every price change happens in every language, forever.
Multi-regional SEO: Same language, several countries — for example English for the UK, Ireland and Canada. Needs genuinely different content per region or the pages compete with each other.
Geotargeted SEO: Any deliberate targeting by place. The line to stay behind: pages that differ only by place name are doorway pages, and they are a policy violation rather than a tactic.

Core technical and structural

Technical SEO: Whether engines can crawl, render, index and understand the site. Everything else depends on it, which is why it is fixed first.
On-page SEO: What is on the page: titles, headings, copy, internal links, structured data, and matching the intent behind the query.
Off-page SEO: Signals from elsewhere — links, mentions, profiles, reviews. Mostly not a coding problem, and the slowest to move.
Mobile SEO: Since mobile-first indexing, the mobile experience is the site as far as ranking is concerned. Not a separate project — a constraint on every decision.
Desktop SEO: Rarely a separate discipline now. It matters where desktop is where conversion happens, which is common in B2B.

Business model and scale

E-commerce SEO: Product and category pages, faceted navigation, product schema, out-of-stock handling. The specialism with the most ways to accidentally create 40,000 useless URLs.
Enterprise SEO: Large sites and larger organisations. The hard part is coordination and governance, not technique.
SaaS SEO: Long consideration cycles, comparison and alternative-to queries, and content that has to survive being read by an evaluator rather than a browser.
B2B SEO: Low volume, high value, multiple stakeholders. Procurement pages, security and data-protection documentation and case studies do more than keyword volume suggests.
B2C SEO: Higher volume, shorter decisions, emotional and price-led triggers.
Startup SEO: Everything on a zero-authority domain. The discipline is choosing beatable targets instead of the head terms the founder wants.
Affiliate SEO: Content built to route traffic to someone else’s checkout. Thin affiliate content has been a repeated target of core updates.
Programmatic SEO: Generating many pages from structured data. Powerful when each page is genuinely useful and gated by a quality rule; the fastest possible route to index bloat when it is not.

Content, format and niche

Content SEO: Planning, writing and maintaining pages that answer real queries — the part of SEO that compounds.
Image SEO: Descriptive filenames, real alt text, modern formats, correct dimensions, and image sitemaps where images are a discovery channel.
Video SEO: Video pages with VideoObject markup, transcripts and chapters. Requires an actual video; marking one up that does not exist is a violation.
YouTube SEO: Ranking inside YouTube, which is its own search engine with its own signals — retention, click-through, session time.
News SEO: Google News and Top Stories. Requires publisher status, speed of publication and news-specific markup. Not applicable to most businesses.
Voice search SEO: Optimising for spoken queries and single spoken answers. Overwhelmingly the same work as answer-engine optimisation plus accurate local data.
App store optimisation (ASO): Ranking in the App Store and Google Play. A different platform entirely — title, keywords, screenshots, ratings and install velocity.

AI and next-generation engines

Generative Engine Optimization (GEO): Being retrievable, extractable and corroborated well enough for AI answer engines to cite you. Prerequisite: the crawlers must not be blocked, which many hosts do silently.
Answer Engine Optimization (AEO): Writing passages that can be lifted whole — answer-first structure, self-contained sentences, tables and Q&A.
AI search SEO: The umbrella term for both, plus the access and measurement work: crawler status codes, referrer tracking and a repeatable prompt test.

Ethical frameworks

White-hat SEO: Working within search engine guidelines. Slower, and the only approach whose results survive an algorithm update.
Black-hat SEO: Deliberate violation — link buying, cloaking, doorway pages, fake reviews, private blog networks. It can work briefly, and the failure mode is losing the site, not losing a ranking.
Grey-hat SEO: Tactics that are not explicitly banned but are clearly against the spirit of the guidelines. The category exists mostly so people can describe black-hat work more comfortably.
Negative SEO: Attacks against a competitor — spam links, scraped duplicate content, fake listings, hacking. The defensive posture is monitoring, security headers, and email authentication.

User experience integration

Search Experience Optimization (SXO): Treating the search result and the landing experience as one journey. Ranking is worthless if the page that ranks does not answer the query or cannot be used on a phone. This is where SEO and conversion work stop being separate.

How to tell which apply to you

Technical, on-page and content SEO apply to every site without exception. Start there.
Add local SEO if a customer’s location changes whether they can buy from you.
Add e-commerce SEO if you sell products online. Add B2B or SaaS patterns if your sale is long and multi-stakeholder.
Add international or multi-regional only when you have market-specific substance — currency, terms, proof — not merely ambition.
Add GEO and AEO now regardless of size: the cost is structural discipline you should apply anyway.
Add image or video SEO when you actually have images or video worth finding.
Ignore anything left over. A quote listing eleven types for a five-page site is a quote for eleven invoices.
