# What is SEO? Search Engine Optimization, explained

> The original — still 50%+ of traffic.

Search Engine Optimization (SEO) is the original discipline: ranking in the blue-link results of Google and Bing. It's still the largest single source of traffic for most sites and the foundation that AEO, GEO, and LLMO are layered on top of. AI didn't kill SEO — it just added new surfaces above it.

## How SEO differs from AEO, GEO, LLMO

SEO targets the ranked blue-link list in classical SERPs. AEO, GEO, and LLMO target the AI-mediated surfaces that appear above and around those links. They share most of the same technical building blocks — Mentionwell optimizes for all four at once because the work is largely the same work.

## How Mentionwell handles SEO

- Per-headline keyword research and topic clustering during onboarding.
- Hub-and-spoke internal linking driven by the site's content taxonomy.
- Title and meta tuning per article, with featured-snippet patterns where applicable.
- Sitemaps, Article schema, descriptive image alt text, and clean canonical URLs.
- Editorial critic pass that flags thin sections, over-claiming, and missing citations before publish.

## Frequently asked questions about SEO

### Is SEO dead?

No. Classic blue-link search is still the largest single source of traffic for most sites. AI engines (ChatGPT, Claude, Perplexity, Google AI Overviews) are rapidly growing channels, but they augment SEO rather than replacing it. Mentionwell ships full SEO underneath AEO, GEO, and LLMO — same article, all four surfaces.

### How does Mentionwell handle classic SEO?

Onboarding builds a content taxonomy and per-headline keyword targets. Articles run through an editorial critic that enforces title and meta length, lead-with-the-answer style, semantic HTML, internal linking, and Article + BreadcrumbList JSON-LD. Sitemaps and per-article canonicals are emitted automatically.

### Does SEO conflict with AEO or GEO?

No — they reinforce each other. The same signals that rank a page (clear topical authority, semantic HTML, fast load, schema) also make it surface as an answer (AEO) and get cited (GEO). Optimizing for one usually drags the others up.

### What's the foundation of an SEO-good article?

One H1 with the primary keyword, a 40–60 word lead that answers the query, a clean H2/H3 hierarchy, internal links to siblings and parents, descriptive image alt text, Article schema, and a stable canonical URL. Mentionwell enforces all of these on every draft.
