Technical SEO checklist for launching discoverable pages

Executive brief

Key takeaways

• Test the final URL for a 200 status and the correct canonical.
• Write a unique title and description for each intent.
• Use one h1 and a logical heading hierarchy.
• Include only canonical, indexable URLs in the sitemap.

A page can compete for discovery only after systems can access it, interpret it and select the correct URL. This checklist covers the minimum technical layer before investing in distribution.

Crawling and response

• The public URL returns status 200.
• robots.txt does not block the page or essential resources.
• There is no accidental authentication, challenge or redirect for crawlers.
• The main HTML contains the content without requiring interaction.

Indexing and canonical

Confirm that the page has no noindex. Use an absolute, self-referencing canonical when this is the primary version. Campaign variations and parameters should not create conflicting signals.

Unique metadata

The title should describe the main intent and distinguish the page. The description should preview the value of reading without promising something the content does not deliver.

Sharing also requires consistent Open Graph and Twitter Card metadata. When there is a social image, use stable dimensions and a composition that remains legible outside the site.

Semantic HTML

Use main, article, header, nav, aside, section and footer according to function. Keep one h1 and do not skip heading levels for visual preference.

Lists should be real lists. Expandable questions work well with details and summary, which provide keyboard interaction without additional JavaScript.

Structured data

Validate Article, Breadcrumb and FAQ markup. Remove empty properties and ensure that titles, dates, authorship and answers match visible elements.

Discovery and maintenance

Add the URL to the sitemap and create at least one contextual internal link. After publishing, monitor indexation, coverage errors, real-user experience and content changes. Technical SEO is an ongoing condition, not a task completed at deployment.

Frequently asked questions

Should every page be in the sitemap?

No. Include only canonical, indexable and relevant URLs. Private, duplicate, parameterized or noindex pages should not appear.

Does the meta description directly affect ranking?

It is not treated as a direct ranking factor, but it can affect understanding and click-through when used in the snippet.

Should every article use Article schema?

Use Article or BlogPosting when the page is actually an article. Markup must represent the type and content visible on the page.
