// three layers

On-page SEO splits cleanly into three layers.

Skip any one and the page can't rank. We diagnose and fix all three on every engagement.

01

Page Indexation

Can the page be crawled, rendered, and indexed? Robots, sitemaps, server health, render budget, JS hydration — the foundation.

02

Page Categorization

Does the page tell Google (and LLMs) what it's about? Titles, headings, schema, entities, semantic relevance, keyword coverage.

03

Page Functionality

Does the page deliver value when it loads? Core Web Vitals, mobile UX, content depth, internal linking, conversion architecture.

// what we tune

Twelve tuning surfaces. Every page.

Each surface has its own playbook. We tune each one against the top-10 results for the target query, then validate with SurferSEO and Cora until the page scores 90+.

TT

Title tags

Unique, concise, descriptive, branded. Under 70 chars.

MD

Meta descriptions

Compelling, intent-matched. Under 160 chars.

HD

Heading hierarchy

H1–H6 as a clean table of contents with keyword weight.

URL

URL structure

Static, dash-separated, descriptive, hierarchical.

SCH

Schema markup

FAQPage, HowTo, Article, Organization, Product — JSON-LD.

ALT

Image alt text

Descriptive, keyword-aware, accessibility-compliant.

IL

Internal linking

No page more than 4 clicks deep. Anchor-text strategy.

CWV

Core Web Vitals

LCP, INP, CLS — measured and tuned per template.

KD

Keyword density

Exact, partial, entity, and LSI in tuned ranges.

DC

Duplicate content

Canonical resolution, http/https consolidation, 301 cleanup.

404

404 / redirect hygiene

Restore or 301 — keep equity flowing, never dead-end.

MOB

Mobile experience

Mobile-first index ready. Touch targets, viewport, speed.

// the checklist

The on-page SEO checklist we run.

Two layers — site-wide foundations and per-page execution. We don't hand-wave these. Every item gets a pass / fail score in the audit.

Site-wide

10 checks
  • robots.txt configured correctly
  • Zero server errors / 5xx
  • Static, organized, descriptive URLs
  • HTML + XML sitemaps in place
  • Content renders from HTML across devices
  • Microformatting / structured data
  • Internal + external links with descriptive anchors
  • All images have alt tags
  • Site speed optimized (LCP, INP, CLS)
  • SSL / HTTPS enforced

Per page

10 checks
  • Title tag under 70 chars, unique, descriptive
  • Meta description under 160 chars, unique
  • Proper H1, H2, H3+ hierarchy
  • URL slug under 90 chars
  • Several hundred words of unique content
  • Target + LSI + entity keywords in tuned density
  • Internal links to topically related pages
  • External links to authoritative sources
  • Schema markup matched to content type
  • Image alt text on all media
// methodology

Three audits. One roadmap.

Every engagement starts with three diagnostic passes. The output is a detailed, fully-repeatable roadmap — the same playbook works across industries.

PG

On-page analysis

Page-by-page review using Google Analytics, Search Console, Core Web Vitals, and keyword research — output: a detailed, industry-agnostic, repeatable ranking roadmap.

CT

Content audit

Keyword research across every page — quality, duplicate content, keyword stuffing, cannibalization, and semantic gaps surfaced in one report.

LK

Backlink audit

Diversity, link velocity, anchor variability, TLD spread, internal link structure — site-wide and page-level health diagnosed.

// tuning score

What a 90+ score means.

We use SurferSEO and SEOToolLabs Corato score every tuned page against the top-10 results for its target query. A score of 90 or above typically indicates the page is structurally and semantically tuned to compete with what's currently ranking.

// faq

On-page questions we get every week.

Why should I engage an on-page SEO specialist?
On-page SEO matters more than ever — especially in the LLM era. Search engines and answer engines both need clean, semantic, structured signals to understand and cite your pages. Link building alone no longer wins; technical on-page tuning is foundational.
Can I test your on-page services?
Yes. Give us a single page or a small batch of pages and we'll show you the tuning lift before you commit to a larger engagement.
Do you guarantee rankings?
We don't guarantee rankings — anyone who does is lying. We do guarantee we'll lift your on-site tuning scores measurably via our extensive audit-and-fix process.
Do I have to sign a long-term contract?
No. But the more pages you have us tune, the greater the discount, and the higher the cumulative ranking impact across your site.
What is a 90+ tuning score?
We use SurferSEO and SEOToolLabs' Cora to score each page against the top-10 results for its target query. A score of 90+ typically means proper tuning — your page is structurally and semantically competitive with what's currently ranking.
Do LLMs read on-page SEO signals?
Yes, but differently. LLMs weight entity recognition, structured data, semantic clarity, and citation patterns more than keyword density. Our on-page work is engineered for both classic SERPs and AI citation surfaces.
