Catalog inclusion and indexation control
Evidence required: an exported URL inventory, Google Search Console indexation data, product status and merchandising records, and a representative crawl from Screaming Frog.
The previously published 50,000+ SKU and 80% no-traffic figures in this checklist are internal examples that still require source reconciliation and should not be used as universal benchmarks. Pass condition: product URLs remain indexable only when the distributor has a current reason for them to be searchable and the page offers useful product information beyond an undifferentiated feed entry.
Fail condition: retired, duplicate, strategically irrelevant, or feed-only URLs remain indexable without a documented inclusion rule. Severity: High
Owner: SEO lead with catalog or merchandising operations
Corrective action: define catalog inclusion rules, consolidate true duplicates with canonical signals where appropriate, use noindex for pages that should remain accessible but not searchable, and remove retired URLs with an appropriate response.
Validation step: recrawl the affected URL set in Screaming Frog and compare indexation and canonical reports in Google Search Console. Tools: Screaming Frog, Google Search Console
Pricing and product structured data accuracy
Evidence required: rendered product-page content, current quantity-tier pricing, the page source or JSON-LD, and structured data test results. The examples price per 100 and price per 1000 are preserved as quantity-tier examples, not as a required schema pattern.
Pass condition: any Product or Offer markup used is supported by the visible page and accurately represents the product, price information, and availability that a buyer can see. Fail condition: markup contains values that are hidden, stale, unsupported, or presented as if special bulk-pricing markup were required for rankings.
Severity: High
Owner: SEO lead with engineering and merchandising
Corrective action: align visible pricing and any applicable structured data, remove unsupported properties, and document how quantity tiers are represented for buyers.
Validation step: compare the rendered page with the JSON-LD and retest the updated markup. Tools: Schema.org, Validator.schema.org
Mobile performance and rendering
Evidence required: PageSpeed Insights results, available field data, key template render checks, and GTmetrix diagnostics for 2 representative catalog pages. Use 2.5 seconds as the LCP target being tested rather than as a promise of ranking improvement.
Pass condition: the primary catalog templates render their main content and conversion controls reliably on mobile, with LCP meeting the stated target in the evidence being reviewed. Fail condition: slow hero assets, script execution, layout dependencies, or blocked resources prevent a buyer or crawler from receiving the main page content promptly.
Severity: High
Owner: Engineering or web performance owner
Corrective action: reduce blocking resources, right-size media, remove unnecessary scripts, and address template-specific causes shown by the diagnostics.
Validation step: rerun the same representative URLs in PageSpeed Insights and GTmetrix after deployment and compare like-for-like results. Tools: PageSpeed Insights, GTmetrix
Faceted navigation and duplicate URL control
Evidence required: crawl exports for filter combinations, Google Search Console indexation patterns, canonical tags, robots.txt rules, internal links, and representative parameter URLs.
Pass condition: filters for attributes such as color, material, and lead time create useful browse states without producing large sets of unintentionally indexable duplicate or near-duplicate URLs. Fail condition: parameter combinations are freely crawlable and indexable without distinct search value, or robots.txt is used as if it alone guarantees removal from the index.
Severity: High
Owner: SEO lead with engineering
Corrective action: decide which filtered states deserve searchable landing pages, consolidate true duplicates with canonicals where appropriate, limit crawl paths through internal linking and parameter handling, and use indexation controls that match the intended outcome.
Validation step: recrawl representative filter paths and review canonical and indexation behavior in Google Search Console. Tools: Google Search Console
