Why a 10-point audit matters
Most SEO tools check only on-page elements (meta tags, headings) or only performance (PageSpeed). Real rankings depend on the full picture — including signals that emerged with AI search: Google AI Overviews pull from FAQPage and HowTo schemas; ChatGPT and Perplexity respect llms.txt; and Core Web Vitals remain a ranking factor for traditional SERPs. This audit covers all three layers in one scan.
The 10 categories we check
- Performance — Google PageSpeed Insights mobile score (Core Web Vitals).
- Meta tags — title length (30-60 chars), description (80-160 chars), OG tags.
- Heading structure — exactly one H1, multiple H2s, logical hierarchy.
- Structured data — JSON-LD schemas count + types (Organization, BreadcrumbList, FAQPage, HowTo).
- Internal linking — minimum 10 internal links, no empty anchor text.
- Image SEO — alt text coverage, lazy loading, modern formats.
- Mobile-friendly — viewport meta tag, responsive signals.
- Technical SEO — HTTPS, canonical, robots.txt, sitemap.xml.
- Content depth — word count benchmark (target 1500+).
- AI/GEO signals — llms.txt presence, FAQPage + HowTo schemas for AI Overviews and ChatGPT citations.
How to use your audit results
Sort by status, not score. A red “poor” check at 40/100 often delivers more ranking lift than improving a yellow “warn” at 75/100. The lowest-scoring category is your biggest opportunity. Fix it, re-run the audit in a week, watch the score climb.
After fixing the red flags, focus on AI/GEO signals next — this is the under-served opportunity in 2026. Most sites have llms.txt and FAQPage scoring 0 because structured data isn’t part of standard WordPress setups. Adding both takes 15 minutes and unlocks AI Overviews + ChatGPT citations.
What this tool doesn’t do
This is a single-page audit. It doesn’t crawl your full site, doesn’t track historical rankings, doesn’t monitor competitors, and doesn’t test pages behind authentication. For those, you need Ahrefs, Semrush, or Screaming Frog — or hire an agency that runs them weekly.
What this tool does: gives you a clear 60-second snapshot of one URL’s SEO health, with specific fixes. Perfect for spot-checking new pages, monitoring after a deploy, or showing clients before/after improvements.
SEO scoring — what each score means
- 90-100 (Excellent) — Top 10% of the web. Maintenance mode — keep monitoring, watch for drift.
- 70-89 (Good) — Above average. Specific fixes will move you to excellent territory.
- 50-69 (Needs work) — Below typical SaaS quality. Each fix is high-leverage. Prioritize red categories first.
- 0-49 (Critical) — Major issues blocking ranking. Likely missing fundamentals like H1, viewport, HTTPS, or structured data.
When to run this audit
Run the audit at four key moments: before launching a new page, after any major deploy, monthly on top-revenue pages, and before/after agency engagements to measure impact. Each scan takes 60 seconds — cheaper insurance than rebuilding rankings after a hidden regression.
5 SEO mistakes we see in 80% of audits
After running this audit on hundreds of sites, these are the recurring patterns. Fix any one of these and your overall score jumps 10-15 points overnight:
- Title tag missing the primary keyword. Your <title> is the strongest ranking signal you control. If your target keyword isn’t in the first 40 characters, you’re asking Google to guess. Fix: put the exact phrase first, brand last.
- Three H1s on one page. Either from a CMS template (header logo + page H1 + hero H1) or from authors not knowing the rule. Multiple H1s confuse Google’s topic extraction. Fix: exactly one H1 per page, with the primary keyword.
- No FAQPage schema. AI Overviews and ChatGPT prioritize structured FAQ content for citations. Adding FAQPage to existing content is a 20-minute win that often unlocks AI traffic that wasn’t accessible before.
- Image alt text missing on 30%+ of images. Especially on WooCommerce, Shopify product images, and blog hero images. Every missing alt is a missed ranking opportunity for image search + accessibility.
- Internal links under 5 per page. Often because designers favor minimal layouts. Pages with 10+ internal links rank better because they pass link equity efficiently and help Google understand topic clusters.

Our audit is the fastest entry point. Once you’ve fixed the issues this surfaces, graduate to Ahrefs or Semrush for the strategic work — backlink building, content gap analysis, keyword expansion.
ROI math — what each 10-point SEO improvement is worth
SEO score isn’t vanity — it correlates directly with organic traffic. Industry benchmarks from Ahrefs’ SEO study show:
- Moving 50 → 60 typically lifts impressions 15-25% over 90 days (mostly long-tail rankings).
- Moving 70 → 80 lifts traffic 30-50% if combined with content additions (entering competitive SERPs).
- Moving 80 → 90 lifts conversion 5-12% (better Core Web Vitals = better mobile conversions).
For an ecommerce site doing €500K/year, a 10-point lift typically pays for itself within 60-90 days through compounding organic traffic. For lead-gen sites, the math is even stronger because each ranking improvement compounds.
SEO timeline — when do improvements show up?
Different fixes have different turnaround times. Don’t panic if rankings don’t move in week one:
- Technical fixes (HTTPS, viewport, canonical): 48-72 hours after Googlebot recrawls. Force re-indexing via Search Console for faster pickup.
- Meta tags + headings: 1-2 weeks. New CTR data flows into ranking signals over ~10 search impressions per page.
- Schema markup: 2-4 weeks for rich snippets to appear. AI Overviews update faster (often within 1 week).
- Performance improvements (Core Web Vitals): 28 days for field data refresh, then 2-4 weeks for ranking signal update.
- Content depth additions: 4-12 weeks for new long-tail rankings, longer for competitive head terms.
The compounding effect kicks in around month 3-4. Sites that consistently ship SEO fixes weekly outrank sites that batch them quarterly — even when total work is equal.
