The theStacc SEO audit tool gives you an illustrative scorecard across the 11 categories and 55+ checkpoints a full SEO audit covers, plus a fix list ranked by impact-to-effort. The scores and metrics are generated in your browser from published industry benchmarks — they are not measurements of your site, and nothing here is pulled from Google or a third-party SEO database. What it is genuinely good for: seeing what an audit covers, how the categories are weighted, and which fixes to start with. Best for small business owners, marketing managers, and SEO professionals who want a structured starting point.
What Does an SEO Audit Cover?
A complete audit spans 11 categories and over 55 individual checkpoints. Each is scored and weighted by impact to produce an SEO Health Score from 0 to 100. The tool above models that scoring so you can see the shape of it; the descriptions below are what a real audit of your site would examine.
Technical SEO (25%) checks your HTTPS setup, robots.txt, XML sitemap, mobile viewport, canonical tags, redirect chains, mixed content, soft 404s, and hreflang tags. These are foundational signals that tell search engines whether they can crawl and index your site properly.
On-Page SEO (20%) evaluates your title tags, meta descriptions, H1 structure, heading hierarchy, internal links, Open Graph tags, and Twitter Cards. These elements directly influence how your pages appear in search results and how users interact with them.
Content Quality (22%) analyzes word count, readability, placeholder text detection, blog presence, content duplication, and passage structure for AI extractability. Content is the #1 ranking factor — thin pages with under 300 words rarely rank for competitive terms.
Performance (15%) covers Core Web Vitals: Largest Contentful Paint (LCP, threshold: 2.0s), Cumulative Layout Shift (CLS), Interaction to Next Paint (INP), Time to First Byte (TTFB), and overall performance score. Speed directly impacts rankings and user experience. To measure these on your own site, run it through Google PageSpeed Insights — it is free and reports your field data.
Authority & Backlinks (10%) covers Domain Rating (0-100), total backlinks, referring domains, referring IPs, broken backlinks, total ranking keywords, position distribution, and estimated monthly organic traffic. The figures the tool shows for this category are modelled from benchmark ratios, not looked up — measuring them for real requires a backlink index, which is what paid platforms sell.
Schema Markup (12%) checks for JSON-LD structured data, LocalBusiness or Organization schema, BreadcrumbList, WebSite with SearchAction, Person/Author, VideoObject, and FAQ schema. Schema helps Google understand your business and enables rich snippets in search results.
AI Search Readiness (5%) evaluates whether your content is structured for AI-powered search engines like ChatGPT, Perplexity, and Google AI Overviews. FAQ sections, Q&A patterns, and indexability all factor in.
GEO / AIO (5%) checks llms.txt compliance, passage structure scoring (150-300 word chunks), direct answer formatting, question-based headings, and content freshness per-platform. AI search is the fastest-growing channel — optimize for it now.
Images (5%) checks alt text coverage and image optimization signals. Images without alt text hurt accessibility and SEO, while unoptimized images slow down your pages.
Analytics (5%) detects your tracking stack — Google Analytics 4, Google Tag Manager, Meta Pixel, LinkedIn Insight, Hotjar, and Microsoft Clarity. Proper tracking is essential for measuring SEO ROI.
Security (5%) checks HTTPS enforcement, HSTS, Content Security Policy, X-Frame-Options, and X-Content-Type-Options headers. Security is a ranking signal and builds user trust.
How the Scoring Works
Your overall score is a weighted average across all 11 categories. Technical SEO and On-Page SEO carry the most weight because they are the foundational signals Google evaluates first. Performance and Content Quality are next, followed by the new Authority & Backlinks category, Schema Markup, AI Readiness, GEO/AIO, Images, Analytics, and Security.
A (90-100): Your site has excellent SEO fundamentals. Focus on content velocity and review generation. B (75-89): Good foundation with specific areas to improve. Check the Top Priorities. C (60-74): Several important checks are failing and likely costing you rankings. D (40-59): Multiple fundamental issues need attention. F (below 40): Critical problems that may be making your site invisible in search.

Frequently asked questions
No — and we want to be plain about that. The scorecard is generated entirely in your browser from the URL you type in, using published industry benchmarks for how typical small-business sites perform in each category. Nothing on your site is fetched, and no figure here comes from Google, from a backlink database, or from any third-party SEO provider. Treat it as a worked example of what a full audit covers and what a realistic starting score looks like — then use the fix list, which applies to almost every site, as your checklist. For measured numbers on your own site, use Google Search Console and Google Analytics.
A complete audit spans 11 categories: Technical SEO (HTTPS, robots.txt, sitemap, viewport, canonical, redirects, mixed content, soft 404s, hreflang), On-Page SEO (title tags, meta descriptions, H1 structure, headings, internal links, Open Graph, Twitter Cards), Content Quality (word count, readability, duplication, blog presence, passage structure), Performance (LCP, CLS, INP, TTFB), Authority and Backlinks (domain strength, backlink count, referring domains, organic visibility), Schema Markup (JSON-LD, LocalBusiness, BreadcrumbList, WebSite, Person, VideoObject), AI Search Readiness (FAQ structure, AI crawler access, Q&A patterns), GEO/AIO (llms.txt, passage structure, freshness), Images (alt text, optimization), Security (headers, HTTPS), and Analytics (GA4, GTM, Meta Pixel, LinkedIn). This tool models a score for each of those categories so you can see how the weighting works and which areas usually cost sites the most points.
A score of 90-100 is excellent (Grade A) with strong SEO fundamentals across all categories. 75-89 is good (Grade B) — solid foundation with specific quick wins remaining. 60-74 is average (Grade C) — focused work in several categories could move you up significantly. 40-59 is poor (Grade D) — multiple critical gaps are likely holding your rankings back. Below 40 is failing (Grade F) — fundamental problems may be making your site nearly invisible in search. Most small business websites score 35-55 on their first audit, which is why the illustrative scores this tool produces sit in that band.
Domain Rating is a 0-100 score that measures the strength of your backlink profile. It is calculated from the number of unique referring domains linking to your site, the authority of those domains, and the topical relevance of the links. Sites with DR 60+ can rank for competitive head terms. DR 40-60 typically ranks for medium-competition keywords. DR 20-40 ranks for long-tail keywords. Below DR 20, you are in the building phase. DR is not a Google metric — it is an industry-standard proxy that commercial SEO platforms each calculate their own way, so the number differs between them. Building DR takes months of consistent link-building through guest posts, PR, partnerships, and creating link-worthy content.
Start with the Top Priorities section — they are ranked by impact-to-effort ratio. Common quick wins (under 30 minutes): fix title tag length, write a meta description, add LocalBusiness schema, enable HTTPS, add a viewport meta tag, fix broken pages. Medium-effort fixes (1-3 hours): add FAQ schema, create an llms.txt file, add heading structure (exactly 1 H1 per page, 3+ H2s), improve internal linking, add alt text to images. High-effort (ongoing): build quality backlinks to improve DR, publish 800+ word service pages, optimize Core Web Vitals, create consistent blog content. The authority category (DR + backlinks) usually has the biggest long-term impact on rankings.
They are modelled, not measured. The tool derives the Domain Rating, backlink count, referring domains, and traffic figures from the illustrative score using the typical ratios published SEO research reports for sites at that level — no backlink database is queried and no provider supplies the numbers. They are there to show you what the metrics mean and how they relate to each other, not to tell you what your site scores. If you need your own measured figures, a paid backlink platform or Google Search Console is the right place to get them.
Yes. The scorecard, the grade, all 11 category scores, and the prioritised fix list are free and instant, with no credit card and no signup. If you want a genuine audit of your site — one where a person and our platform look at your actual pages, rankings, and backlinks — you can book that through the demo link, and we will tell you what the real numbers are. We never sell or share contact information.
Every issue identified in your audit maps directly to a theStacc feature. Missing or weak title tags? theStacc auto-optimizes every title for search. No meta descriptions? theStacc writes click-worthy descriptions for every page. Thin content? theStacc publishes 30+ in-depth articles monthly in your brand voice. Low DR? theStacc places you in relevant articles and builds contextual links. Missing schema markup? theStacc auto-generates LocalBusiness and FAQ schema.

Run a comprehensive audit monthly if you are actively working on SEO, or quarterly for maintenance monitoring. Run an audit immediately after any major site change: redesign, CMS migration, URL restructuring, or bulk content publishing. Track your score over time — a 10-point improvement typically correlates with 15-25% organic traffic growth within 3-6 months. Set a baseline, fix the top 3 priorities, re-audit in 30 days, and repeat.
AI search readiness measures how well your website is structured to be cited by AI-powered search engines: ChatGPT, Perplexity, Google AI Overviews, Gemini, and Claude. Four signals decide it: FAQ schema or question-format H2 headings (AI Overviews pull from these first), whether your robots.txt blocks AI crawlers (GPTBot, ClaudeBot, PerplexityBot), the presence of an /llms.txt file (emerging standard for AI guidance), and whether content is structured with clear question-and-answer formatting that AI can extract. AI search is the fastest-growing discovery channel — sites optimized for it gain visibility as traditional search evolves.
