TECHNICAL SEO · CONTENT · PERFORMANCE · AEO/GEO · TRACKING
Every SiteAuditLint feature to crawl, fix, compare and improve your website
A desktop SEO auditor that scores, ranks and remembers every audit, checks your tracking tags, and shows whether AI search engines can read your site and cite it. Crawls, history and reports stay on your computer.
100 URLs free. No credit card required.
Crawl: 149 URLs in 1 minute. 84 healthy, 0 broken.
Screens from a sample audit of northwindapparel.com, a demo apparel store.
CRAWL ENGINE
A full-site crawl, categorized as it runs.
Hundreds to thousands of URLs, crawled locally and sorted into healthy, needs attention, redirected, broken and blocked. Every crawl ends in a weighted score, not just a raw count.
- Technical SEO, content, performance and AEO/GEO checks in one pass
- Respects robots.txt, sitemaps and authenticated crawling
- Configurable crawl depth and URL exclusions
AUDIT SCORE
One number, weighted so it means something.
Critical issues pull the score down hard, while opportunities barely move it. You get a single, defensible number to track over time or hand to a client, instead of a pile of unranked warnings.
- Weighted across all categories, not a flat average
- Four severity tiers: Critical, Warning, Opportunity, Info
- Plain-language rating: Excellent, Good, Needs Work, Poor
ISSUES
Every issue explained, with the URLs to prove it.
Group issues by type or list every row. Pick one to see its severity, impact and effort, why it matters for search, how to fix it, and each affected URL with evidence you can copy or export.
- Quick wins listed above the table, largest first
- Critical, Warning, Opportunity and Info counts at a glance
- Status code totals for 2xx, 3xx, 4xx, 5xx and blocked URLs
ACTION PLAN
Ranked by impact and effort, not alphabetically.
Every audit produces a prioritized to-do list. High-impact, low-effort fixes surface first, so a slow page or 8 missing meta descriptions never get buried under a title that runs one character long.
- Impact and effort scored High, Medium or Low
- "Why it matters" and "how to fix" on every issue
- Exact affected URLs and evidence, exportable to CSV or PDF
COMPARE & HISTORY
Your audits remember every crawl.
Run a new audit and instantly see what's new, fixed, increased, decreased, or unchanged, per issue rather than just a headline score delta.
- Unlimited local audit history, no expiry
- Score charted across every audit run
- Compare any two audits, not just consecutive ones
AEO / GEO READINESS
Can AI search engines actually read you?
Classic SEO doesn't tell you whether ChatGPT, Claude or Perplexity can crawl and cite your site. SiteAuditLint checks nine major AI crawlers against your robots.txt automatically, plus llms.txt and question-led content structure.
- GPTBot, ClaudeBot, PerplexityBot, Google-Extended and more
- llms.txt detection
- Flags pages missing question-style H2/H3s for FAQ-style citation
AI VISIBILITY
Find out if ChatGPT actually cites you.
Answer Engine Readiness tells you AI crawlers can reach your pages. AI Visibility tells you whether AI answers use them. Add the questions your customers ask, choose the models, and SiteAuditLint records every answer where your site is cited or mentioned, and which competitors appear instead. Prompts go from your computer straight to each provider on your own API keys.
- ChatGPT, Gemini, Claude and Perplexity, with several runs per prompt
- Results by prompt, model, cited site, your cited pages and competitors
- Cost estimate before each check, then export to CSV or post to Slack
TRACKING & PIXELS
Audit your tags without opening Tag Manager.
SiteAuditLint finds every analytics tool, tag manager, ad pixel and event on the site, reads inside each GTM container, and flags what needs fixing: Universal Analytics code still on the page, marketing tags hard-coded outside GTM, pages missing the analytics tag, and GTM tags with no trigger. Turn on Render JavaScript to also see which tags fire, the cookies they set, and anything that tracks visitors before consent.
- GTM, GA4, Google Ads, Meta Pixel and Universal Analytics, with IDs and page coverage
- Every GTM tag with its trigger, event and parameters
- Consent tool and Google Consent Mode detection, plus a Tracking score
Your data never leaves your machine.
No account, no upload, no third-party server holding your crawl data or client sites. Every audit, history file, and export lives on your desktop.
- Crawl offline
- Store history locally
- Export CSV, PDF, HTML
- One-time purchase
