What Does an SEO Audit Check?
A comprehensive SEO audit examines 14 critical on-page factors that directly influence how Google ranks your pages. Each check maps to a specific ranking signal that search engines evaluate when crawling your site. According to Google's SEO Starter Guide, getting these fundamentals right is the foundation of any SEO strategy.
The 14 Ranking Factors We Check
1. Title Tag Optimization
Your title tag is the single most important on-page SEO element. It appears as the clickable headline in search results and tells Google what your page is about. The ideal length is 30-60 characters. Pages with optimized title tags rank an average of 3-5 positions higher than pages with missing or poorly formatted titles.
2. Meta Description
While meta descriptions don’t directly influence rankings, they significantly impact click-through rate (CTR). A well-written meta description between 120-160 characters acts as ad copy for your page in search results. Pages with custom meta descriptions see 5-10% higher CTR.
3. Heading Hierarchy (H1-H6)
Your page should have exactly one H1 tag containing your primary keyword, followed by H2s for major sections and H3s for subsections. Proper heading hierarchy helps Google understand your content structure and can earn you featured snippets.
4. Image Alt Text
Every image on your page should have descriptive alt text for accessibility and Google Image search. Alt text should describe the image content naturally — not be stuffed with keywords.
5. Internal Links
Internal links pass authority between your pages and help Google discover your site structure. Aim for 3-5 internal links per page pointing to related content.
6. External Links
External links to authoritative sources signal that your content is well-researched and trustworthy. Aim for 2-5 external links per page to relevant, high-authority domains.
7. HTTPS Security
Google has confirmed HTTPS as a ranking signal since 2014. Pages served over HTTP are flagged as "Not Secure" in Chrome, which kills user trust and increases bounce rate.
8. Viewport Meta Tag
The viewport meta tag ensures your page renders correctly on mobile devices. Since Google uses mobile-first indexing, a missing viewport tag means your page won’t rank well in mobile search results.
9. Canonical Tag
The canonical tag tells Google which version of a page is the preferred version when duplicate or similar content exists. Without it, Google may split ranking signals between duplicates.
10. Robots Meta Directives
The robots meta tag controls whether Google can index your page. A misconfigured "noindex" directive will completely remove your page from search results.
11. Schema Markup
Structured data helps search engines understand your content type. Pages with schema markup are eligible for rich results (star ratings, FAQ dropdowns) that dramatically increase click-through rates.
12. Open Graph Tags
Open Graph tags control how your page appears when shared on social media. While not a direct ranking factor, social shares drive traffic that creates engagement signals Google monitors.
13. Word Count
Data consistently shows that top-ranking pages for informational queries average 1,400-2,000 words. Pages under 300 words are flagged as "thin content" and struggle to rank for competitive keywords.
14. Content Quality Signals
Google’s helpful content system evaluates whether your content provides genuine value. This includes original information, comprehensive coverage, and E-E-A-T expertise signals.
How Often Should You Audit Your Site?
Run a full site audit monthly and after any major content or design changes. For active blogs publishing weekly or daily, audit new pages within 48 hours of publishing to catch issues before Google indexes them. Fix critical issues first (missing title tags, broken HTTPS, noindex directives), then warnings (missing schema, short content), then optimizations.
For best results, combine monthly audits with Google Search Console monitoring, which alerts you to critical issues in real time.
On-Page Audit vs Full Site Audit
This tool performs an on-page audit analyzing a single URL for all 14 ranking factors. A full site audit crawls your entire website to find broken links, duplicate content, crawl errors, and site-wide patterns. Both are essential for comprehensive SEO.
Common SEO Issues Found in Audits
- Missing or duplicate title tags — the #1 most common issue, found on 30%+ of pages
- No meta description — forces Google to auto-generate a snippet
- Multiple H1 tags — confuses search engines about the page’s topic
- Images without alt text — missed opportunity for image search traffic
- No internal links — orphan pages that Google struggles to discover
- Missing HTTPS — Google explicitly downgrades non-secure pages
- No schema markup — missed opportunity for rich results that boost CTR 20-30%
- Thin content under 300 words — Google considers this low-value
How to Fix SEO Audit Issues
Priority 1
Critical Fixes
Missing title tags, noindex directives, broken HTTPS, missing H1 tags. Fix these first — they directly prevent ranking.
Priority 2
Warnings
Thin content, missing schema markup, no external links, missing image alt text. These limit how well you can compete.
Priority 3
Optimization
Title tag length, meta description wording, keyword placement, internal link anchor text. These move you from page 2 to page 1.
