How to Do an SEO Audit: Step-by-Step Guide for Beginners

Running your first SEO audit can feel overwhelming. Where do you even start? What tools do you need? How do you know what’s actually wrong?

This guide breaks down the entire SEO audit process into manageable steps. By the end, you’ll have a clear picture of your website’s SEO health and a prioritized list of fixes.

What You’ll Need Before Starting

Before diving in, gather these free tools:

• Google Search Console - Essential for indexing data and search performance
• Google Analytics - Traffic and user behavior data
• Google PageSpeed Insights - Core Web Vitals and performance analysis
• Screaming Frog (free up to 500 URLs) - Site crawling and technical analysis
• A spreadsheet - To track issues and prioritize fixes

If you want to speed things up, Rankture’s free SEO audit can scan your site automatically and generate a prioritized report.

Step 1: Crawl Your Website

The first step is understanding what pages exist on your site and how they’re connected.

Using Screaming Frog (Free)

1. Download and install Screaming Frog SEO Spider
2. Enter your website URL and click “Start”
3. Let it crawl (may take minutes to hours depending on site size)
4. Export the results to analyze

What to Look For

• Total pages found - Does this match what you expect?
• Response codes - 200 (good), 301/302 (redirects), 404 (broken), 500 (server errors)
• Indexability - Which pages are indexable vs blocked?
• Duplicate content - Pages with identical or near-duplicate content

Step 2: Check Google Search Console

Search Console shows you what Google actually sees and any issues it’s found.

Key Reports to Review

Coverage Report:

• How many pages are indexed?
• What errors are preventing indexation?
• Are there pages you don’t want indexed that are indexed?

Performance Report:

• Which queries bring traffic?
• What’s your average position?
• Which pages get the most clicks?

Core Web Vitals Report:

• Are your pages passing or failing?
• Mobile vs desktop performance

Common Issues to Flag

• Pages marked “Discovered – currently not indexed”
• Pages with “Crawled – currently not indexed”
• Duplicate pages without canonical
• Pages excluded by robots.txt or noindex

Step 3: Analyze Technical SEO

Technical issues can block your entire site from ranking. Check these critical elements:

Robots.txt

Find yours at yourdomain.com/robots.txt. Check:

• Is it blocking important pages or resources?
• Is it allowing crawlers to access CSS and JavaScript?
• Does it reference your sitemap?

XML Sitemap

Find yours at yourdomain.com/sitemap.xml. Verify:

• Does it exist and load properly?
• Are all important pages included?
• Are there any 404 or redirected URLs in it?
• Is it submitted in Search Console?

HTTPS & Security

• Does your entire site load over HTTPS?
• Do HTTP URLs redirect to HTTPS?
• Is your SSL certificate valid?
• No mixed content warnings?

Site Speed

Run PageSpeed Insights on your key pages:

• Homepage
• Main category/service pages
• Top blog posts
• Product pages (if e-commerce)

Note your Core Web Vitals scores:

• LCP (Largest Contentful Paint): Should be under 2.5s
• INP (Interaction to Next Paint): Should be under 200ms
• CLS (Cumulative Layout Shift): Should be under 0.1

Step 4: Audit On-Page SEO

On-page SEO is what you control on each individual page.

Title Tags

Export all title tags from your crawl. Check for:

• Missing titles - Every page needs one
• Duplicate titles - Each page should be unique
• Too long/short - Aim for 50-60 characters
• Keyword inclusion - Primary keyword should appear
• Branding consistency - Include brand name where appropriate

Meta Descriptions

Similarly, check your meta descriptions:

• Missing descriptions - Important for CTR
• Duplicates - Each should be unique
• Length - 150-160 characters optimal
• Compelling copy - Does it encourage clicks?

Heading Structure

For each important page, verify:

• One H1 tag per page
• H1 includes target keyword
• Logical hierarchy (H1 → H2 → H3)
• Headings describe content sections

Images

• All images have alt text
• Alt text is descriptive (not “image1.jpg”)
• Images are compressed
• Using modern formats (WebP preferred)

Step 5: Evaluate Content Quality

Google’s Helpful Content Update makes content quality more important than ever.

Content Audit Questions

For each piece of content, ask:

1. Does this fully answer the search intent?
2. Is the information accurate and current?
3. Does it provide value beyond competitors?
4. Is there evidence of expertise (author bio, credentials)?
5. Would you trust this for important decisions?

Identify Problem Content

Flag content that is:

• Thin - Under 300 words with little value
• Outdated - Information that’s no longer accurate
• Duplicate - Same content on multiple pages
• Cannibalizing - Multiple pages targeting same keyword
• Underperforming - No traffic, no rankings, no purpose

Recommended Actions

For each problem page, decide:

• Update - Add depth, freshen information
• Consolidate - Merge similar pages
• Redirect - Point to better content
• Remove - Delete and 404 (or noindex)

Step 6: Check Internal Linking

Internal links distribute authority and help users navigate.

What to Analyze

• Orphan pages - Pages with no internal links pointing to them
• Deep pages - Important pages buried too deep (more than 3 clicks from home)
• Broken links - Links pointing to 404 pages
• Anchor text - Is it descriptive and varied?

Quick Wins

• Add links to orphan pages from relevant content
• Create hub pages linking to related content
• Fix or remove broken internal links
• Link from high-authority pages to pages you want to rank

Step 7: Review Mobile Experience

With mobile-first indexing, your mobile site IS your site to Google.

Mobile Checks

• Site is fully responsive
• Text readable without zooming
• Touch targets (buttons, links) appropriately sized
• No horizontal scrolling required
• No mobile-specific errors in Search Console

Test Your Site

• Use Chrome DevTools mobile emulation
• Test on actual devices
• Run Mobile-Friendly Test

Step 8: Prioritize and Create Action Plan

You’ve found issues. Now what? Not everything is equally important.

Priority Framework

Critical (Fix immediately):

• Indexing blockers (robots.txt, noindex errors)
• Security issues (HTTPS, mixed content)
• Major broken functionality

High (Fix within 1-2 weeks):

• Core Web Vitals failures
• Missing/duplicate title tags
• Broken internal links
• Thin content on important pages

Medium (Fix within 1 month):

• Missing meta descriptions
• Image alt text
• Content consolidation
• Internal linking improvements

Low (Ongoing optimization):

• Minor content updates
• Additional internal links
• Structured data enhancements

Next Steps After Your Audit

An audit is just the beginning. Here’s what to do next:

1. Create a tracking spreadsheet - List all issues, priority, and status
2. Set up monitoring - Track rankings, traffic, Core Web Vitals
3. Schedule regular mini-audits - Monthly checks for new issues
4. Measure impact - Compare before/after metrics
