Diagnostic Sprint

A short, evidence-based engagement for teams that are already publishing or measuring a site, but cannot tell which defect is blocking search, clicks, inquiries, or reliable production.

The output is a written scope memo and repair queue. It is not a traffic guarantee, link-building package, ad-management offer, or generic strategy deck.

Best fit

Search impressions exist, but clicks or inquiries are weak.
GA4/GTM, forms, CTAs, or outbound-click routes may be misreported.
AI-assisted pages are scaling, but quality gates and rollback evidence are uneven.
The team needs a repair order before approving implementation work.

What the sprint checks

Area	Question	Output
Search route	Are impressions, titles, page intent, and internal links aligned?	CTR and page-family repair notes.
Measurement route	Can clicks, CTAs, forms, and outbound routes be trusted?	Event-map and missing-field list.
Publishing route	Do pages pass visible-copy, schema, rollback, and quality checks?	Severity-ranked defect queue.
Sales route	Can a useful page turn into a qualified inquiry without pressure or fake proof?	CTA and inquiry-path repair notes.

Inputs to send

One paragraph on what the site or workflow is trying to do.
Three to five URLs or local artifacts that show the problem.
Any public dashboards or exported screenshots you are comfortable sharing.
A short note on what decision the diagnostic should support.

Do not send passwords, private customer lists, payment data, or production credentials in the first email.
