Top 3 issues from the 2 free modules

Missing FinancialProduct schema across 14 lending pages. AI Visibility module flag. Without it, AI models cannot identify these pages as lending products. Single biggest contributor to the D AI Visibility grade. Fix detail in Pro tier.
Cumulative Layout Shift exceeds 0.1 on 8 of 12 sampled pages. Technical SEO module flag. Largely driven by web font loading and lazy-loaded above-fold images. CLS budget breakdown in Pro tier.
AI bot allowlist incomplete. OAI-SearchBot, Claude-SearchBot and PerplexityBot are not explicitly allowed; relying on wildcard fallback. Run the Web3 Robots.txt Checker to fix this in 5 minutes.

// Why crypto-tuned matters

Why a generic SEO audit misses what actually moves crypto rankings

Generic free SEO tools are good at generic SEO. They were not built for crypto. The gap shows up across four distinct layers a Web3 site cares about.

Generic SEO audit

Backlinko, Semrush, SEOptimer, AIOSEO, HOTH, Ubersuggest

Validates generic Product schema, not FinancialProduct or CryptoExchange
Treats DefiLlama and Trail of Bits as moderate-quality referrers
No AEO citation testing across ChatGPT, Perplexity, Claude
No smart contract security signals (GoPlus Honeypot, Buy/Sell tax)
No on-chain trust signals (token holder decentralization, liquidity)

Crawlux · Web3-tuned

23 specialized analyzers · 80+ checks across 8 modules

FinancialProduct, CryptoExchange, Organization JSON-LD validation
Web3 Backlink Toxicity Rubric recognizes 80+ authority sources
30+ category prompts tested across 3 LLMs in Pro tier
GoPlus security scan, honeypot detection, tokenomics analysis
Token holder decentralization, on-chain transfer velocity

The expensive misconception

A site can pass every generic audit cleanly while still failing the checks that actually move ranking and AEO for crypto.

The other gap is pricing. Generic tools charge subscriptions designed for SEO agencies. A crypto protocol usually needs to audit one site (its own) plus a few competitors per year.

Semrush

$140

/ month

~$1,680 / year

Ahrefs

$129

/ month

~$1,548 / year

Sitebulb

$35

/ month

~$420 / year

Crawlux Pro

$25

one-time per domain

~$100 / year for 4 audits

For a deeper look, the Token Schema module ships the copy-paste JSON-LD library. The AI Visibility module covers AEO at depth. The Competitor Analysis module shows the dashboard preview.

// Module map

The 8 modules at a glance

Each module is a parallel scan. The free first audit runs all 8 in under 4 minutes. Click any module on the diagram to see what it actually checks.

Generic SEO tools ship a single linear crawl. Crawlux runs 8 independent analyzer chains in parallel. The trade-off: deeper specialization per module, no shared assumptions. A token page that fails Token Schema doesn't automatically fail Technical SEO. Each finding has its own scope and its own fix.

// Methodology delta

Crypto-tuned audit vs generic SEO tools

Side by side, what a generic SEO tool catches vs what Crawlux catches on the same crypto site. Same domain, same crawl, different findings.

Check category	Generic SEO tool	Crawlux
Token page schema	Flags missing Product schema	Validates FinancialProduct, tickerSymbol, chain context, contract address
Exchange page schema	Suggests Organization schema	Validates CryptoExchange, currenciesAccepted, areaServed, fee structure
AI engine citation	Not measured	60-prompt test across ChatGPT, Perplexity, Claude with citation share
Backlink toxicity	Generic spam score	Crypto-PBN detection, casino vertical bleed, AI farm patterns
Keyword intent	Commercial vs informational	6 Web3-calibrated buckets including investigation and disambiguation
YMYL trust signals	E-A-T checklist	Audit report disclosure, conflict-of-interest byline, jurisdictional disclosure
Wallet connect flow	Not checked	Detects CSR wallet UI, missing fallback content, AI bot accessibility
Competitor benchmark	Same-niche generic competitors	Top 20 by category (DEX, lending, wallet, etc), per-module score delta

Generic tools were built for e-commerce, content sites, local business. They have 12+ years of refinement on those use cases. Crawlux was built for crypto from day one. That's the only meaningful difference and it shows up in every module.

// Findings distribution

What we find most often in crypto audits

From 312 audits run in April 2026 across DeFi, exchange, NFT, wallet and L1 sites. Percentage of sites with at least one finding in each category.

Token schema errors 81%

Client-side rendered hero content 68%

AI bots blocked in robots.txt 54%

Missing YMYL disclosures 47%

Toxic backlinks above 15% of profile 42%

Generic byline or no named author 38%

Below median AI citation share 29%

Core Web Vitals failing on mobile 23%

Token schema errors lead by a wide margin. 81% of audited token pages had at least one schema issue blocking AI citation. The hierarchy of leverage: schema first, then SSR, then AI bot allowlist, then YMYL disclosures. Knock out these four and most crypto sites jump 2-3x on AEO citation rate within 90 days.

// AI engine data

Where AI engines cite crypto sites

From our Q1 2026 AEO test across 200 crypto sites and 60 prompts. Top citation sources by engine. Reddit, Coingecko, Defillama dominate. Notable: protocol docs outrank both news sites and Wikipedia across all three engines.

Source	ChatGPT	Perplexity	Claude
reddit.com	11.2%	19.3%	8.4%
defillama.com	9.4%	7.6%	11.2%
coingecko.com	8.6%	8.1%	7.3%
coinmarketcap.com	7.2%	6.7%	5.9%
protocol docs (combined)	6.8%	5.2%	9.7%
wikipedia.org	5.4%	5.8%	6.1%
etherscan.io	4.1%	3.8%	5.2%
youtube.com (named channels)	5.3%	4.6%	3.1%
cointelegraph.com	3.4%	3.1%	2.6%
bankless.com	2.8%	2.4%	3.7%

Reddit dominates Perplexity. Protocol docs win on Claude. Defillama is consistent across all three. The actionable read: invest in documentation as a primary AEO surface, maintain real Reddit presence, claim and update CoinGecko and CMC profiles. Anything beyond these four levers has diminishing returns.

// Audit timeline

What runs in those 4 minutes

Most audits finish in under 4 minutes for a typical crypto site. Here's what runs in each phase, and why some modules are slower than others.

The AI Visibility module is the long pole. 60 prompts run against ChatGPT, Perplexity, and Claude in parallel batches with cooldowns to avoid rate limits. Six other modules complete in under 2 minutes total. PDF generation is the final 20 seconds.

// Industry benchmarks

Median composite scores by vertical

Composite Crawlux score (0-100) by vertical, based on Q1 2026 audit data. Higher scores cluster around mature L1 ecosystems with developer-first documentation. Lower scores cluster around newer protocols and memecoins where execution quality varies wildly.

Vertical	Sites tested	Median score	Top decile	Biggest gap vs leader
L1 / L2 chains	50	68	87	Docs surface area
DEXes	40	61	82	Token schema completeness
Wallets	30	59	79	Supported chains list (CSR)
Lending protocols	30	57	81	YMYL disclosures
CEXes	30	54	78	CryptoExchange schema usage
NFT marketplaces	20	48	71	Collection schema, royalty disclosures
Memecoins / new tokens	42	31	63	Everything (low effort baseline)

Where you fall on this distribution depends on category. L1 chains have a 68 median because the leaders (Ethereum Foundation, Solana, Arbitrum) ship complete documentation as primary content. Memecoins have a 31 median because most ship a single landing page and ignore everything else. The gap between your score and the top decile in your category tells you the realistic ceiling, not the absolute one.

// Free crypto SEO audit FAQ

Common questions about the audit

If you have a question not answered here, the pricing page covers tier differences and the audit modules page covers methodology by module.

What does the free crypto SEO audit cover?

The free tier covers ~25 of 80+ checks, focused on Technical SEO and AI Visibility (AEO). You get a 6-page PDF with Crawlux branding showing your scores, the top issues pulling your scores down and a brief fix list. The full Pro tier ($25 one-time per domain) covers all 80+ checks across 8 modules including Token Schema, YMYL trust signals, smart contract security, backlink toxicity, keyword intent and competitor benchmark, with a 23-page white-label PDF and copy-paste fix code.

How is this different from generic SEO audit tools?

Generic tools (Backlinko SEO Checker, Semrush SEO Checker, SEOptimer, AIOSEO, Ubersuggest, HOTH SEO audit) cover the open web. They check title tags, meta descriptions, page speed, generic schema and basic backlinks. Crawlux runs all of those plus the crypto-specific layers: FinancialProduct schema instead of generic Product, GoPlus Honeypot detection on token contracts, Web3 Backlink Toxicity Rubric that recognizes DefiLlama and CoinGecko as authority sources, AEO citation testing across ChatGPT, Perplexity and Claude with crypto-category prompts. A site can pass a generic audit cleanly while failing the checks that actually move ranking and AEO for crypto.

Is this really free?

Yes. The first audit on any domain is free, no signup required for the basic check. We rate-limit free audits per IP to manage compute and API costs. You get a 6-page sample PDF, the AEO score, the SEO score and the top issues. Optional: provide an email to receive the full PDF report and a follow-up sequence on closing the highest-impact issues.

Why one-time pricing instead of subscription?

Most SEO audit tools (Semrush, Ahrefs, Moz, Sitebulb, SE Ranking) charge $99-$500 per month for unlimited audits. For a crypto protocol that needs to audit one site (its own) plus a handful of competitors, you end up paying for capacity you do not use. Crawlux is one-time per domain: $25 per audit, $49 for team workspace, with a 90-day re-audit window included. If you audit 4 sites a year, your annual SEO tooling spend is $100-$200 instead of $1,200-$6,000.

What categories does Crawlux work for?

Every major crypto category. DeFi protocols (lending, DEX, liquid staking), centralized exchanges, NFT marketplaces and GameFi, crypto wallets, Layer 2 chains, oracles, cross-chain bridges, infrastructure tools, crypto media sites and Web3 SaaS. The Crypto Keyword Intent Classifier auto-detects your category and tunes the audit (different schema patterns, different competitor benchmarks, different prompt sets) per category.

Does the free audit include AI visibility testing?

Yes. The free tier runs the AI Visibility (AEO) module which includes citation testing across ChatGPT, Perplexity and Claude with 5 category-relevant prompts plus the AEO score with diagnostic breakdown across 4 readiness dimensions. The full Pro tier expands to 30+ prompts plus competitor citation comparison plus prioritized fix list. AI visibility is one of the highest-leverage areas right now and we wanted it accessible in the free tier.

How long does an audit take?

End-to-end audit takes about 2 minutes from domain submission to PDF download. The 23 specialized analyzers run in parallel and the PDF is generated in real time using Puppeteer. For Pro tier, you get an email when the report is ready; for Free tier the report is shown immediately on screen with PDF download available.

What happens after I run the free audit?

You can keep the free PDF, share it, use it as a baseline. If you want the full picture, upgrade to Pro ($25) for the same domain you already audited and enable all 8 modules, the 23-page white-label PDF, copy-paste fix code, top 20 competitor benchmark and a 90-day re-audit window. Or run the audit on competitor domains to spot-check positioning. Or use one of the more focused free tools (AI Citation Checker, Token Schema Tester, Backlink Toxicity Check) to drill into a specific area.
