What is the RoastMyUrl guide for?

It helps understand what RoastMyUrl analyzes, how to interpret results and which corrections to prioritize.

What’s the difference between quick audit and deep scan?

The quick audit checks the main signals of a page or site, while the deep scan more broadly explores page models, structural inconsistencies and cross-cutting technical signals.

Is the llms.txt file mandatory?

No. It’s not a mandatory web standard. It’s an optional file useful for providing a structured entry point to certain assistants and agents.

When to relaunch an audit?

After an important correction: title, indexation, performance, structured markup, robots.txt, sitemap.xml or template change.

Preamble

Introduction

RoastMyUrl is not designed as a simple tag checker. Its engine is built to transform a raw technical assessment into an actionable decision for founders and decision-makers.

Objective of this guide

Provide a reading framework to distinguish vital authority signals from peripheral cosmetic optimizations.

What this guide doesn't do

It doesn't promise any ranking magic. It documents structural prerequisites necessary to technically exist in the market.

Golden rule: Never address a performance optimization or Schema.org enrichment before securing the fundamentals (Indexability and Base Structure).

Scope

Audited Signal Matrix

The algorithm evaluates the page’s ability to be correctly ingested, understood and restituted by third-party agents (Search engines or Language models).

SEO Structure

Primary markup consistency: Title, Meta, H1, document hierarchy and canonical tags.

Indexability & Access

Robots.txt directives, sitemap integrity, HTTP statuses and crawl blocking prevention.

Front Performance

HTML payload volume, first response velocity (TTFB) and architecture efficiency.

Trust (E-E-A-T)

Security protocol validation (HTTPS), no mixed-content, and presence of business authority signals.

AI-Ready Signals

Semantic entity extraction, JSON-LD format integration and detection of the emerging llms.txt standard.

Social Vector

OpenGraph protocol completeness to ensure clean information syndication.

Interpretation

Severity Hierarchy

The strength of an audit lies in its sorting ability. Results are ranked by their immediate impact on your visibility.

Designates fatal errors that literally prevent the machine from accessing or understanding the page: access blocked by robots.txt, 500 errors, total absence of title, or unacceptable server response time.

Fundamentals

Le socle SEO immuable

The emergence of AI does not erase the structural rules of the web. Penalized sites generally fail on basic hygiene principles.

1. Balise <title>

It remains the primary intent signal. It must be unique, explicit and carry the target entity.

2. Meta Description

Ensures control of the search "snippet". Its role is strictly oriented towards click-through rate (CTR).

3. Architecture Hn

An exclusive H1 followed by a logical tree (H2, H3). This disambiguates page reading for the bot.

4. Tag Canonical

Protection against internal cannibalization. It designates the absolute source of truth to the engine.

Business Intelligence

Optimisation GEO (Generative Engine)

Generative Engine Optimization (GEO) requires shifting from a "Keywords" logic to a "Knowledge Graph" logic.

Entity Density

AI analyzes topics. Make sure your business concepts, services and authors are clearly identifiable in raw text.

Schema.org (JSON-LD)

It's the universal translator. It structures information (FAQ, Product, Organization) so it's ingested without margin of error.

Noise Reduction

LLMs are sensitive to signal-to-noise ratio. Ultra-concentrated text is statistically more likely to be retained as a source.

The llms.txt protocol: Although optional, placing an llms.txt file at the server root helps guide autonomous agents towards your company’s essential documentation.

Performance

Infrastructure Velocity

A slow TTFB (Time to First Byte) or massive payload generates algorithmic friction that can force crawlers to abandon reading.

Trust

Trust Engineering

Engines grant a premium to security and asset readability. Server errors degrade the trust capital ("Crawl Budget").

Secure Protocols

The SSL certificate (HTTPS) must be impeccable. No asset (Image, CSS) should be loaded via unsecured HTTP protocol.

Code Hygiene

Strict monitoring of 4xx (Not Found) and 5xx (Server) errors is imperative to maintain URL authority.

Redirect Chains

Multiple redirect loops or chains dilute PageRank and waste bandwidth allocated to robots.

Standard Files

Declaration Assets

Implementing files at the domain root allows you to dictate engagement rules to the different machines scanning your infrastructure.

robots.txt

It’s your server’s law. It allows (Allow) or prohibits (Disallow) exploration of specific paths by bots.

sitemap.xml

The official map of your strategic URLs. Must be maintained dynamically, without 404 errors or orphan pages.

Basic syntax (Robots)

User-agent: *
Allow: /
Sitemap: https://votre-domaine.com/sitemap.xml

Workflow

The Optimal Action Sequence

The success of an audit lies in execution discipline. Here is the sequential roadmap recommended by our engineers.

Remove accidental noindex directives, fix invalid certificates, restore the H1 tag and ensure TTFB is below the critical threshold.
