SEO Technical Health Crawlability, Indexation & On-Page Technical Foundations

Is the site built correctly for search engines to crawl, index, and understand it? This service covers the technical foundation—crawl errors, indexation, robots.txt, sitemaps, canonical tags, duplicate content, meta descriptions, heading structure, schema markup, internal linking, mobile-friendliness, and redirect chains.

What this service is

The SEO Technical Health service evaluates whether a client’s website is properly structured for search engines to crawl, index, and interpret its content. Even sites with strong content and good design can underperform in search results if technical foundations are broken—pages blocked from indexing, redirect chains that dilute link equity, missing or duplicate meta descriptions, orphan pages that never get crawled, or schema markup that Google cannot parse.

Northwoods offers a clear progression: a free automated homepage scan that checks the most critical technical signals in under five minutes, a full-site crawl report using Screaming Frog with prioritized remediation steps, a comprehensive audit with Google Search Console analysis and a live walkthrough with Alex, and an ongoing retainer that monitors technical health monthly and applies remediation from the client’s backlog budget.

Why clients care: Google cannot rank pages it cannot find, crawl, or understand. A single misconfigured robots.txt rule can deindex an entire site section. Redirect chains bleed PageRank on every hop. Duplicate content fragments ranking signals across multiple URLs. Most clients have no visibility into these issues until organic traffic drops—and by then the damage has compounded over months.

Alex
SEO Specialist — Technical Health & Strategy
Alex owns both SEO Technical Health and SEO Strategy & Rankings at Northwoods. For S-tier engagements, Alex runs Screaming Frog crawls and produces the branded remediation report. For M-tier audits, Alex manually reviews Google Search Console data, analyzes log files when available, and leads a 1–2 hour live walkthrough of all findings prioritized by impact and effort. On L-tier retainers, Alex performs monthly re-crawls, flags new issues, and applies remediation hours from the client’s elected backlog budget.

Cross-service coordination: At the L-tier retainer level, Alex and Ed K (Paid Media) share a keyword universe document so paid and organic strategies don’t compete. For example, if a client already ranks #1 organically for a high-value keyword, there is no reason to also bid on it in Google Ads—freeing that budget for terms where organic coverage is weak.

Alex — Retainer
F-tier automation note: The F-tier agent (seo-scanner) is currently planned, not yet in production. The scan requires no credentials—all checks are performed against the publicly accessible homepage. Automation feasibility is HIGH because every check is a deterministic HTTP request or HTML parse with a clear pass/fail threshold.

L-tier dashboard KPIs

For retainer clients, the following KPIs are tracked on the NWS-360 client dashboard and reviewed in monthly or biweekly check-ins with Alex. These metrics drive the ongoing remediation agenda and surface regressions before they impact organic traffic.

KPI What it measures
Technical SEO Health Score (0–100) Composite score based on crawl errors, indexation rate, redirect health, on-page completeness, and mobile rendering. Target: >80. Trended monthly to track improvement or regression.
Crawl Error Count Total number of crawl errors (4xx, 5xx, soft 404s) detected per crawl cycle. Target: 0 critical errors. Broken down by error type and page priority.
Indexation Rate (Pages Indexed vs. Submitted) Percentage of pages submitted via sitemap that are actually indexed by Google. Target: >95%. A declining rate signals crawl budget problems, noindex leaks, or quality issues.
Page Speed / Lighthouse Performance Core Web Vitals and Lighthouse performance score for key landing pages. Shared with the CWV service when both are active. Target varies by page type—typically >75 for mobile.

What makes this service distinctive

Cross-service relationships

SEO Technical Health is one half of Alex’s SEO practice. The other half—SEO Strategy & Rankings—covers keyword research, content gap analysis, ranking tracking, and organic growth planning. Technical Health ensures the site can be found; Strategy & Rankings ensures it ranks for the right terms.

Paid + Organic alignment: At the L-tier retainer level, Alex and Ed K (Paid Media) maintain a shared keyword universe document. This prevents the client from paying for clicks on keywords where they already rank #1 organically, and ensures paid media budget is allocated to terms where organic coverage is weak or competitive. This coordination is a built-in feature of any NWS-360 retainer that includes both SEO and Paid Media services.
Page Speed / CWV overlap: The Lighthouse Performance KPI in this service shares data with the Core Web Vitals service (when both are active on a retainer). Technical SEO focuses on crawlability, indexation, and on-page structure; CWV focuses on load speed, interactivity, and visual stability. Both feed the same client dashboard.
