Technical checks should answer a simple question: can search engines and users reliably reach, load, and understand the pages that matter? Event planning sites often combine large hero images, gallery scripts, embedded media, and archived event pages, so the audit should rely on page-level evidence rather than assumptions.
Checklist item: Largest content paint on important templates. Evidence required: field data in Search Console when available, plus a repeatable lab check in Google PageSpeed Insights for the homepage, primary service pages, and representative portfolio pages.
Pass condition: the relevant field metric is not failing, and the largest visible element is not being delayed by an avoidably oversized asset; use 2.5 seconds as the reference threshold for the good range when interpreting the metric.
Fail condition: the template repeatedly reports poor loading experience or the hero asset is clearly the bottleneck. Severity: critical for templates that affect most organic entrances. Owner: developer with content or design support.
Corrective action: resize oversized source files, use efficient formats, preload only the true critical image when appropriate, and remove scripts that block initial rendering. Validation: rerun the same URLs and monitor field data after deployment. Tools: Google PageSpeed Insights, Search Console.
Checklist item: Structured data accuracy. Evidence required: the rendered page, existing JSON-LD, and validation output. Pass condition: LocalBusiness or Event markup, when used, describes visible facts accurately and does not claim properties the page does not support.
Fail condition: markup conflicts with visible content, uses an inapplicable type, or contains validation errors that prevent correct interpretation. Severity: high when inaccurate data could misrepresent the business or a published event.
Owner: developer or SEO lead. Corrective action: remove unsupported properties, align values with the page, and retain only schema that matches the entity represented. Validation: test the live page with Schema.org and Validator.schema.org and inspect Search Console reports where relevant.
Checklist item: Portfolio image delivery. Evidence required: a representative image inventory showing source dimensions, file format, rendered dimensions, and transfer size. Pass condition: portfolio images are appropriately sized for their rendered use, modern formats are used where compatible, and below-the-fold media is not forced to load before it is needed.
Fail condition: large legacy assets are transferred at full resolution for small displays or galleries load all images immediately. Severity: high. Owner: developer with the creative team. Corrective action: create responsive derivatives, convert suitable files to WebP or AVIF, and apply native lazy loading where it does not interfere with the primary visual. Validation: compare network transfer and visual quality before and after. Tools: Squoosh.app, ShortPixel.
Checklist item: Crawl and index path depth. Evidence required: a crawl from Screaming Frog or Sitebulb, internal link reports, and a sample of priority service and case-study URLs. Pass condition: important pages are reachable through normal internal links and priority pages are not buried beyond 3 clicks from a useful entry point without a business reason.
Fail condition: key services or case studies are orphaned, accessible only through scripts, or isolated behind deep archive paths. Severity: critical for orphaned revenue pages and high for secondary case studies.
Owner: SEO lead and developer. Corrective action: add descriptive internal links from relevant navigation, service hubs, portfolio indexes, and editorial pages. Validation: recrawl and confirm the intended pages are discoverable through standard HTML links.
Checklist item: Indexation controls and canonical consistency. Evidence required: robots directives, canonical elements, XML sitemap membership, and Search Console inspection for representative URLs.
Pass condition: pages intended for search can be crawled, canonical tags point to the preferred version, and duplicate gallery or filtered URLs are not competing unintentionally. Fail condition: important pages are blocked, canonicalized elsewhere by mistake, or omitted from discoverable site structures without reason.
Severity: critical. Owner: developer or technical SEO lead. Corrective action: align directives, canonicals, sitemaps, and internal links with the intended indexable version. Validation: inspect the live source, recrawl, and recheck representative URLs after search engines have had an opportunity to process the changes.
