Dra. Marcia Babo — Website, SEO and conversion for a medical practice

Google Tag Manager and the tags it brings blocked the main thread for about 2.8 s in mobile Lighthouse. Instead of dropping measurement, loading was deferred to the first interaction, with a 4 s maximum wait and a last attempt when the tab is closed. Because the dataLayer is created in the head, no click is lost along the way: events queue up and GTM processes them on start. Button tracking is a single inline click listener in the head, and the button components stay Server Components, with no client JavaScript.

Each condition, symptom, service and article is a TypeScript file with its own type. A script scans the folders and generates the registry, so creating a page means writing a file and running a command. Drafts never reach the sitemap, not even in previews, and lastmod comes from the content's review date. For share images, Next's generator (next/og) broke the project's build, so each page gets a static JPG produced by a sharp script, which also removes server cost.

Public Doctoralia reviews are fetched on the server, parsed with cheerio and cached for 24 hours. Without the cache, every visit would fire up to four external requests and the home page would depend on the other site's uptime. If the fetch fails, the section falls back to a placeholder text. The route that exposes the same data limits the pages it accepts and uses edge caching, so it doesn't become an open scraping gateway.

Medical advertising is regulated, and the site's copy has to respect that. On the technical side this became structure: content versioned in files, a review date on every page, drafts separated from what is published, and a tracking and privacy audit documented alongside the code, with risks prioritized by effort.
