SEOCastell method

Diagnose, prioritize, implement, verify, report.

The method keeps SEO work connected to business decisions. Each engagement starts with evidence, turns priorities into shippable tasks, and closes the loop with live verification and readable reporting.

Diagnose
Segment the site by template, intent, indexation status, market value, and conversion role before deciding what to fix.

Prioritize
Score each opportunity by commercial upside, implementation effort, release risk, and the strength of available evidence.

Implement
Ship focused technical, content, internal-linking, schema, UX, and tracking improvements in accountable sprints.

Verify
Re-crawl, inspect rendered pages, validate analytics events, and monitor the affected URL groups after release.

Report
Translate ranking, indexation, traffic, lead quality, and revenue signals into the next decision for the business.

SEO scorecard

Metrics used to judge whether SEO work actually helped.

The scorecard changes by project type, but every metric must answer a decision question: did visibility improve, did the right pages become more useful, and did the business receive better demand?

Organic traffic

Sessions and users from non-paid search, segmented by branded, non-branded, market, and page role.

Impressions

Search Console visibility trends by query cluster, template, country, device, and funnel stage.

Indexation

Useful indexable URLs, excluded URLs, canonical patterns, sitemap hygiene, and crawl discovery.

Qualified leads

Forms, calls, demo starts, quote requests, WhatsApp taps, and CRM-qualified enquiries from organic journeys.

Organic revenue

Last-click and assisted revenue for ecommerce categories, product groups, or quote-driven services.

Core Web Vitals

LCP, INP, CLS, field data coverage, and template-level performance constraints.

Crawl budget

Waste from parameters, duplicate pages, soft 404s, redirects, orphaned URLs, and low-value archives.

Ranking clusters

Movement for groups of semantically related queries rather than isolated vanity keywords.

GBP actions

Calls, directions, profile views, booking clicks, website visits, photo engagement, and review signals.

Conversion quality

Lead source feedback, sales acceptance, assisted paths, and page-level conversion friction.

Individual case study template

A repeatable page structure for every SEO case study.

Hero

Hero with title, anonymized context, result snapshot, primary CTA, and the project type filter.

SEO

SEO brief containing meta title, meta description, slug, target keyword groups, search intent, and schema recommendations.

Executive

Executive summary with the initial problem, strategic response, implementation window, and modeled or anonymized results.

Client

Client context, initial SEO problem, audit findings, strategy, implementation, results, lessons learned, and next steps.

Infographic

Infographic brief summarizing the problem, decision framework, action sequence, and result scorecard.

FAQ

FAQ section with eight long-form answers suitable for FAQPage schema.

Contextual

Contextual internal links, authoritative external references, final CTA, Article schema, FAQPage schema, and BreadcrumbList schema.

UX and SEO recommendations

Make the rubric premium, indexable and conversion-ready.

UX/UI recommendations

Use a compact filter bar above the case grid so prospects can scan by project type without leaving the page.
Give every case card a concrete result snapshot, not only a category label, so the grid feels evidence-led.
Keep each study readable with short sections, metric tables, callout bands, and clear next-action CTAs.
Show the method and scorecard before the case grid to explain how SEOCastell thinks, not only what it sells.
Place internal service links inside the body where they help the reader choose a next action, not in a generic link dump.
Use anonymized or modeled result language visibly so the page stays credible and avoids overclaiming.

Technical SEO recommendations

Add every case study URL to the XML sitemap with self-referencing canonical URLs and clean trailing-slash paths.
Use Article, FAQPage, BreadcrumbList, Organization, and WebPage JSON-LD on case study pages.
Keep each H1 unique and align it with the primary keyword, while using H2 sections for audit, strategy, implementation, results, and FAQ.
Use descriptive image alt text and captions for card images and infographic briefs.
Cross-link each study to the most relevant SEOCastell service pages and one related blog guide.
Avoid thin tag or archive pages; the main case study index should be the canonical hub for filtering and discovery.
Monitor Search Console index coverage, query clusters, impressions, and organic assisted conversions after publication.
