# Blocks & formats

TMN doesn't pour an article out of a single template. It assembles each one from small building **blocks** — so no two articles share a fixed skeleton, and commercial blocks are placed by strategy rather than pasted on at the end. Think Lego, not templates.

## Three block families

Every article is composed from blocks in three families:

* **Editorial blocks** — the prose and structure: intros, sections, key takeaways, FAQs, step lists, conclusions. No product or profile data.
* **Product blocks** — bound to a product (real, from your catalog, or AI-synthesized): product cards, comparison tables, pros & cons, rating breakdowns, where-to-buy.
* **Conversion blocks** — bound to a [profile](/core-concepts/profiles.md): CTA, pricing, testimonials, trust signals. These carry the monetization in lead-gen and SaaS articles.

Blocks are rendered by **Content Egg**. For the full catalog and what each block looks like, see the Content Egg docs: [EggBlocks introduction](https://ce-docs.keywordrush.com/egg-blocks/introduction) and the [block reference](https://ce-docs.keywordrush.com/egg-blocks/block-reference).

## Formats

A **format** is the kind of article — review, how-to, comparison, and so on. It's a genre *guideline*, not a rigid template: the AI decides the exact outline and block mix within the format's boundaries. TMN has **16 formats**, in two groups:

* **Product-first formats** — the article is built around products, so products are resolved **before** the outline is written. Examples: product reviews, roundups ("best of"), comparisons, alternatives, gift guides.
* **Content-first formats** — the content comes first; where product slots fit, they're filled afterward with products **relevant to that section**. Examples: how-tos, buying guides, troubleshooting, explainers, FAQs.

See the [Article formats](/reference/formats.md) reference for the full list.

## How blocks and formats come together

You don't place blocks by hand. For each article, the AI composes the block mix from three inputs:

* **Format** — sets the natural shape (a review reads differently than a how-to).
* **Intent** — money/mixed articles include commercial blocks; info articles stay editorial.
* **Monetization model** — decides whether the commercial blocks are product blocks or profile-driven conversion blocks.

A few blocks are simply switched on or off by your **Generation Preset** — for example price-comparison blocks, YouTube embeds, or the table of contents. Everything else is composed automatically.

## What you control

* **Per article** — set the **Format** and **Intent** in the node drawer; see [Edit your Topic Map](/building-a-site/edit-topic-map.md).
* **Which formats a plan may use** — in the new-plan wizard, under **Basics → Advanced settings → Allowed formats**, you can limit TMN to specific formats. **Leave it empty (recommended)** so TMN picks the best format for each topic.
* **Across a plan** — toggle optional blocks and writing style in your Generation Preset; see [Use presets](/building-a-site/presets.md).
