Boosting the SEO Score From 40 to 95: The Scanly Checklist We Applied
Posted on October 9, 2026 · Case study
A local home-services site came to us with an SEO score of 40: invisible service pages, 6-second mobile loads, duplicate titles everywhere. Thirty days later: 95. No link building, no redesign — just the checklist below, executed pillar by pillar. Every step was verified with a Scanly scan. Steal the sequence for your own site, starting with our SEO score improvement guide.
Starting point: what a 40 looks like
| Pillar | Before | After |
|---|---|---|
| Indexation | 12 pages noindexed, 3 redirect chains | 100% indexable, clean sitemap |
| Speed (mobile LCP) | 6.1s | 2.3s |
| Titles / schema | 31 duplicates, no schema | Unique titles + LocalBusiness/FAQ schema |
| Trust | No security headers, poor contrast | HSTS/nosniff, AA contrast, alt text |
The 30-day execution
Week 1 — Indexation triage (40 → 58)
Removed a staging noindex left on 12 pages, fixed 3 redirect chains, submitted a clean XML sitemap, flattened www/non-www duplicates with self-canonicals. Biggest single win: 12 invisible pages re-entered the index within days.
+18 points. Lesson: nothing else matters until pages are indexable.
Week 2 — Speed: images + caching (58 → 74)
Compressed 200+ images to WebP (avg. 1.8 MB → 180 KB), enabled host caching + Cloudflare CDN, removed a 5 MB homepage slider and two unused page-builder add-ons. Mobile LCP dropped from 6.1s to 2.3s.
+16 points. Lesson: images are always the biggest LCP lever on brochure sites.
Week 3 — Content signals (74 → 86)
Rewrote 31 duplicate title tags, added meta descriptions to every service page, fixed heading order (three competing H1s per page), added LocalBusiness + FAQ schema, and wrote unique intros for 9 thin location pages.
+12 points. Lesson: titles and schema are the cheapest ranking-adjacent wins in local SEO.
Week 4 — Trust layer: mobile, a11y, security (86 → 95)
Fixed tap-target spacing on mobile nav, lifted body-text contrast to 4.5:1, added alt text to 60 images, enabled HSTS + nosniff + referrer-policy headers, and fixed mixed-content warnings on 8 pages.
+9 points. Lesson: the last stretch is trust signals — small individually, decisive together.
Copy-paste checklist
- Scan and fix indexation blockers — noindex, chains, sitemap, canonicals.
- Compress images to WebP, enable caching + CDN, remove slider bloat.
- Rewrite duplicate titles, add descriptions, fix H1 order, add schema.
- Fix mobile tap targets, contrast, alt text, and security headers.
- Re-scan weekly; hold gains with a monthly routine. Full method: technical SEO audit guide.
Frequently Asked Questions
Did rankings improve too, or just the score?
Both — but on different clocks. The score moved in 30 days; local-pack visibility and calls followed over the next 60 as Google recrawled and engagement improved. Technical health is the prerequisite, not the whole game.
Can I replicate this without an agency?
Yes — every fix above used CMS settings, free plugins, and free tools. The agency value was sequencing and speed, which this checklist now gives you directly.
Conclusion
40 → 95 in 30 days with zero link building: indexation first, speed second, content third, trust last. Run your baseline scan today and work the same sequence.
