How to Do an SEO Audit Step by Step: 2026 Complete Checklist

How to do an SEO audit step by step is an essential skill for anyone who wants their website to rank on Google. According to Backlinko research, 94% of websites have at least one critical SEO issue that’s hurting their rankings. Most business owners don’t know what’s broken — so they can’t fix it.

An SEO audit is like a health checkup for your website. It identifies what’s working, what’s broken, and what needs to be fixed. Without an audit, you’re guessing. With one, you have a prioritized roadmap to higher rankings.

In this guide, I’ll show you exactly how to do an SEO audit step by step — using free tools — covering technical SEO, on-page optimization, content quality, backlinks, and local SEO.

What Is an SEO Audit? (And Why You Need One)

An SEO audit is a systematic inspection of your website to identify issues that prevent it from ranking well on Google. It covers four main areas:

• Technical SEO: Can Google find, crawl, and index your pages?
• On-Page SEO: Are your individual pages optimized for target keywords?
• Content Quality: Is your content helpful, unique, and up-to-date?
• Off-Page SEO (Backlinks): Do other authoritative sites link to you?

Signs you need an SEO audit:

• Traffic has plateaued or dropped
• You’ve never audited your site before (or it’s been over 6 months)
• You recently redesigned or migrated your site
• You’ve received a manual action penalty in Google Search Console
• Your competitors are outranking you for important keywords

Rafirit Station performs comprehensive SEO audits for 50+ businesses annually.

Step 1: Technical SEO Audit (Can Google Find You?)

Technical SEO ensures search engines can crawl, index, and render your pages correctly. If Google can’t find your pages, nothing else matters.

Check 1: Google Search Console — Coverage Report

1. Log into Google Search Console → Click “Pages” under Indexing
2. Look for “Error” and “Excluded” pages
3. Common errors: 404 not found, server errors (5xx), redirected URLs
4. Fix: Remove or redirect broken pages, fix server errors with your host

Check 2: Crawl Your Site with Screaming Frog

1. Download Screaming Frog (free version crawls 500 URLs)
2. Enter your domain → Click “Start”
3. Review the “Response Codes” tab: Any 404s (broken links) or 301/302 redirects?
4. Review “Page Titles” and “Meta Descriptions”: Any missing or duplicate?

Check 3: XML Sitemap

1. Check if you have a sitemap: yourdomain.com/sitemap.xml
2. In Google Search Console → Sitemaps → Is it submitted? Any errors?
3. Fix: Generate sitemap (using Yoast SEO or Rank Math plugin) and submit to GSC

Check 4: Robots.txt

1. Check your robots.txt: yourdomain.com/robots.txt
2. Is it blocking important pages? Look for “Disallow: /”
3. Fix: If “Disallow: /” exists, remove it (unless you want to block all search engines)

---

Step 2: On-Page SEO Audit (Are Your Pages Optimized?)

On-page SEO ensures each individual page is optimized for your target keywords.

Check 1: Title Tags

What to check: Each page should have a unique title tag (50-60 characters) with primary keyword near the beginning.

How to check: Screaming Frog → Page Titles tab → Look for missing, duplicate, too long, or too short titles.

Fix: Rewrite missing or poor titles. Example: “Home | My Business” → “Digital Marketing Agency in Dhaka | My Business”

Check 2: Meta Descriptions

What to check: Each page should have a unique meta description (150-160 characters) with primary keyword + compelling CTA.

How to check: Screaming Frog → Meta Descriptions tab → Look for missing or duplicate descriptions.

Fix: Write compelling descriptions that encourage clicks. Not a ranking factor, but CTR matters.

Check 3: Heading Structure (H1, H2, H3)

What to check: Each page should have ONE H1 (main headline). H2s for main sections. H3s for subsections.

How to check: Screaming Frog → H1s tab → Look for missing H1, multiple H1s, empty H1.

Fix: Add missing H1. Ensure only one H1 per page. Include primary keyword in H1.

Check 4: Image Alt Text

What to check: Every image should have descriptive alt text (helps accessibility and image search).

How to check: Screaming Frog → Images tab → Check for missing alt text.

Fix: Add alt text to all images. Describe the image and include keywords naturally. Example: “red-running-shoes-side-view” not “IMG_4921.jpg”

Check 5: Internal Links

What to check: Are you linking between your own pages? Broken internal links?

How to check: Screaming Frog → Response Codes tab → Look for 404s in internal links.

Fix: Add internal links to related content. Fix or remove broken links.

---

Step 3: Content Quality Audit (Is Your Content Helpful?)

Google’s helpful content update rewards unique, valuable, user-first content. Thin or duplicate content hurts rankings.

Check 1: Thin Content (Pages with Little Value)

What to check: Pages with less than 300 words that aren’t meant to be short (e.g., contact page is fine at 100 words; blog post at 200 words is not).

How to check: Screaming Frog → Word count report (add custom extraction). Or manually review.

Fix: Expand thin content to 500-2,000+ words with original insights, examples, and data.

Check 2: Duplicate Content

What to check: Identical or near-identical content on multiple URLs (common with ecommerce category pages).

How to check: Google Search Console → Search for your page title. Do multiple URLs rank for the same content?

Fix: Use canonical tags to point to the preferred URL. Rewrite duplicate content to be unique.

Check 3: Outdated Content

What to check: Pages with old statistics, expired offers, or references to events that passed.

How to check: Manually review your most important pages (homepage, about, services, top blog posts).

Fix: Update statistics, remove expired offers, refresh examples. Add “Last updated” date.

Check 4: Keyword Cannibalization

What to check: Multiple pages targeting the same keyword — they compete against each other.

How to check: Google Search Console → Search for a keyword. Does it show multiple of your pages?

Fix: Merge pages, redirect duplicates to the strongest page, or differentiate topics.

---

Step 4: Backlink Audit (Who Links to You?)

Backlinks are one of Google’s top ranking factors. Quality matters more than quantity.

Check 1: How Many Backlinks Do You Have?

What to check: Total backlinks and referring domains (unique sites linking to you).

How to check: Ahrefs Webmaster Tools (free) → Dashboard → Backlinks and Referring domains.

Benchmark: New site: 10-50 referring domains. Established site: 100-1,000+.

Check 2: Toxic Backlinks (Spam)

What to check: Links from spammy, irrelevant, or low-quality sites that could hurt your rankings.

How to check: Ahrefs → Backlinks → Sort by “Domain Rating” low to high. Review links from DR 0-10 sites.

Fix: Use Google’s Disavow Tool (only if you have manual penalty or obvious spam). For most sites, ignore low-quality links — Google ignores them naturally.

Check 3: Competitor Backlinks

What to check: Where are your competitors getting backlinks that you’re missing?

How to check: Ahrefs → Backlinks → Enter competitor URL → See their top backlinks.

Fix: Reach out to those same sites with your content (if better/updated).

---

Step 5: Local SEO Audit (For Local Businesses)

If you serve customers in a specific city or area, local SEO is critical.

Check 1: Google Business Profile (GBP)

What to check: Is your GBP verified and fully optimized?

How to check: Search for your business on Google Maps. Does it appear? Is all info correct?

Fix: Complete all sections: hours, description, attributes, photos, products, services.

Check 2: NAP Consistency (Name, Address, Phone)

What to check: Is your business name, address, and phone number identical across your website and all directories?

How to check: Search for your business name + city. Check top 10 directory listings.

Fix: Update inconsistent citations. Use exact same spelling, abbreviation, and formatting everywhere.

Check 3: Local Reviews

What to check: How many reviews do you have? What’s your average rating?

How to check: Google Maps listing → Check review count and rating.

Fix: Implement review collection system (email/SMS request after purchase). Respond to all reviews.

---

Step 6: Core Web Vitals & Page Speed Audit

Page speed is a ranking factor for both mobile and desktop searches.

Check 1: Core Web Vitals (LCP, FID, CLS)

What to check: Largest Contentful Paint (loading speed), First Input Delay (interactivity), Cumulative Layout Shift (visual stability).

How to check: Google Search Console → Core Web Vitals report. Or PageSpeed Insights → Enter your URL.

Passing scores: LCP under 2.5 seconds, FID under 100ms, CLS under 0.1.

Fix: Optimize images, enable caching, remove render-blocking resources, use a faster host.

Check 2: Mobile Usability

What to check: Is your site mobile-friendly? Text readable without zooming? Buttons tappable?

How to check: Google Search Console → Mobile Usability report.

Fix: Use responsive design, increase font size (16px+), ensure buttons are 44px+.
