A website audit is only as useful as its thoroughness. Miss a category and you miss the issues hiding in it. This guide walks you through every phase of a modern website audit - from preparation to action plan - covering SEO, GEO, content quality, and conversion readiness.
Whether you use SiteCrawlIQ or another tool (or a combination of tools and manual checks), this process applies.
Phase 1: Preparation (15 Minutes)
Before you crawl a single page, set yourself up for a productive audit.
Define Your Goals
What triggered this audit? Your goals shape what you prioritize:
Traffic dropped - Focus on technical SEO and indexing issues
Launching a new site - Focus on foundational technical checks and content completeness
Competitors outranking you - Focus on content gaps and competitive benchmarking
AI search visibility - Focus on GEO readiness factors
Conversion rate optimization - Focus on CRO and user experience checks
Routine quarterly check - Cover everything at a high level
Gather Baseline Data
Pull these before you start so you have a comparison point:
Google Search Console - Impressions, clicks, average position for the last 90 days
Google Analytics - Traffic by channel, bounce rates, conversion rates
Previous audit results - If you have them, compare against prior findings
Core Web Vitals report - From Search Console or PageSpeed Insights
Set Your Scope
Decide what you are auditing:
Full site - Every crawlable page (recommended for first audit or quarterly reviews)
Specific section - Just the blog, just product pages, just landing pages
Sample audit - A representative sample of 50-100 pages (useful for very large sites as a quick check)
Phase 2: Technical Crawl (1-5 Minutes)
This is where automated tools earn their value. A crawler visits every page and checks structural health.
Using SiteCrawlIQ
Log in and add your site URL
Click "Start Crawl" - the hybrid crawler (Cheerio + Playwright) discovers pages via sitemap and internal links
For a 200-page site, this typically completes in 30-60 seconds
For larger sites, adjust the page limit in your plan settings
What the Crawl Checks
For every discovered page, the crawl records:
Status code (200, 301, 302, 404, 500)
Title tag (presence, length, uniqueness)
Meta description (presence, length, uniqueness)
H1 tag (presence, count, uniqueness)
Content length (word count)
Internal links (count, broken links)
External links (count, broken links)
Canonical tag (presence, correctness)
Robots meta directives (noindex, nofollow)
Page load time (in milliseconds)
Content type and encoding
What to Look For Immediately
After the crawl completes, check these first:
Any 500 errors - Server errors indicate infrastructure problems that affect all users
Redirect chains - URLs that redirect more than once waste crawl budget and slow page loads
Missing title tags - Pages without titles are essentially invisible to search engines
Duplicate content signals - Multiple pages with the same title or content
Phase 3: Technical SEO Analysis (20 Minutes)
With crawl data in hand, systematically work through the technical categories.
Crawlability and Indexing
Are all important pages returning 200 status codes?
Is your XML sitemap complete and submitted to Search Console?
Does robots.txt block anything it should not?
Are there orphan pages (pages with no internal links pointing to them)?
Check crawl depth - can every important page be reached within 3 clicks from the homepage?
Site Architecture
Is the URL structure logical and hierarchical?
Do breadcrumbs reflect the site structure accurately?
Is navigation consistent across all pages?
Are pagination and canonical tags handling multi-page content correctly?
Security and Performance
Is HTTPS enforced site-wide with no mixed content?
Are Core Web Vitals passing? Check LCP (under 2.5s), INP (under 200ms), CLS (under 0.1)
Is the site mobile-responsive?
Are images optimized (compressed, modern formats, correct dimensions)?

Phase 4: On-Page SEO Review (20 Minutes)
Title Tags
Every page should have a unique title under 60 characters
Titles should include the primary keyword naturally
Check for truncation in search results
Avoid duplicate titles across different pages
Meta Descriptions
Every page should have a unique meta description under 160 characters
Descriptions should be compelling and include a call to action where appropriate
While not a direct ranking factor, good descriptions improve CTR
Heading Structure
Exactly one H1 per page
H2s break content into logical sections
H3s provide subsection structure
No skipped heading levels
Pages with proper heading hierarchy are 2.8x more likely to be cited by AI engines
Internal Linking
Every important page should receive internal links from other pages
Anchor text should be descriptive (avoid "click here")
Link to your most valuable pages from your highest-authority pages
Check for broken internal links
Phase 5: Content Quality Assessment (30 Minutes)
This phase benefits most from human review, even when using automated tools.
Quantitative Checks (Automated)
Word count distribution - flag pages under 300 words
Content uniqueness - check for internal duplicate content
Reading level - is your content appropriate for your audience?
Freshness - when was content last updated?
Qualitative Review (Manual)
For your top 10-20 pages by traffic or business importance:
Does the content fully answer the user's query?
Is the information accurate and current?
Are there content gaps compared to competing pages?
Is E-E-A-T demonstrated (author credentials, citations, experience)?
Does the content include statistics, examples, and actionable advice?
Phase 6: GEO Readiness Audit (10 Minutes)
This is the phase most auditors still skip - and it is increasingly the most impactful.
AI Crawler Access
Check your robots.txt for these essential directives:
GPTBot (OpenAI/ChatGPT) - Allow
Google-Extended (AI Overviews) - Allow
ClaudeBot (Anthropic/Claude) - Allow
PerplexityBot (Perplexity) - Allow
Applebot-Extended (Apple Intelligence) - Allow
About 26% of top websites still block GPTBot. If you are among them, you are invisible to ChatGPT's 883 million monthly users.
llms.txt File
Check for presence at yoursite.com/llms.txt. If it does not exist, create one. This is a 30-minute task with outsized impact. See our [llms.txt guide](/blog/how-to-check-llms-txt) for format details.
Schema Markup Coverage
Organization schema on the homepage (minimum)
WebSite schema with SearchAction
Article/BlogPosting schema on content pages
FAQPage schema where appropriate
BreadcrumbList on interior pages
Content Citability
Evaluate your content against AI citation factors:
[P1] Fix 45 missing meta descriptions - Use CMS bulk editor.
[P2] Add FAQ schema to 20 blog posts - Install schema plugin, configure.
[P3] Compress 200+ unoptimized images - Use ShortPixel bulk optimizer.
Track Progress
Re-run the audit after completing each priority tier. Compare scores to confirm improvements and catch any regressions introduced by the changes.
Key Takeaways
Preparation matters - define goals and gather baselines before crawling
Technical crawling should be automated; content review benefits from human judgment
GEO readiness is the most commonly skipped audit phase and often the most impactful
AI-powered analysis connects data points and prioritizes fixes that humans might miss
Every audit must end with a prioritized action plan, not just a report
Re-audit after fixes to confirm improvements and catch regressions
Frequently Asked Questions
How long does a complete website audit take?
Using automated tools with manual review of key pages, a thorough audit of a 200-page site takes about 2 hours. The automated crawl and analysis take 5-10 minutes; the rest is manual review and action plan creation. Sites over 1,000 pages may need a full day.
Should I audit staging or production?
Always audit production. Staging environments often have different configurations, blocked crawlers, and placeholder content that produces misleading results. The only exception is pre-launch audits of a new site or redesign, where staging is all that exists.
What if my audit finds hundreds of issues?
This is normal, especially for first audits. Do not try to fix everything at once. Focus on P0 and P1 issues first. Many lower-priority issues can be addressed through improved processes (e.g., requiring meta descriptions before publishing) rather than retroactive fixes.
Can I audit a competitor's site?
You can crawl publicly accessible competitor pages to benchmark technical factors. You will not have access to their analytics or Search Console data, but crawl-level data (titles, schema, page speed, GEO readiness) provides valuable competitive intelligence.
