Illustrative situations used inside the curriculum to demonstrate diagnostic method, not records of specific client engagements.
The scenarios below are illustrative composites used for teaching purposes inside the course modules. They are not descriptions of specific client results and should not be read as a claim about outcomes.
Why scenarios instead of results
Technical SEO problems tend to repeat across sites in recognizable shapes: a faceted navigation quietly consuming crawl budget, a hreflang implementation missing return tags, a Core Web Vitals score that regressed after a framework migration. The scenarios in this course are built around those recognizable shapes so the diagnostic process transfers directly to whatever site a student is actually working on.
A mid-size ecommerce staging site exposes filter combinations as crawlable URLs, generating thousands of near-duplicate pages. The lab walks through identifying the pattern in log data, then deciding between robots.txt exclusion, canonical tags, or parameter handling based on which internal links actually matter for discovery.
A staging template shows a healthy lab score but a poor field CLS reading. Students trace the discrepancy to a font-loading strategy that behaves differently under real network conditions.
A five-language staging site has hreflang annotations that reference the correct pages but miss reciprocal return tags, causing inconsistent locale targeting. The lab isolates the missing pairs using a crawler tool.
A batch of staging pages shows as "Crawled, currently not indexed" in the Page Indexing report. The scenario walks through checking canonical signals, thin content, and internal linking depth as the three most common explanations before concluding with a documented root cause.
