What these articles cover
Posts describe markup for organizations, local businesses, breadcrumbs and articles, and explain why the data must match what visitors can actually see on the page.
Benefits and pitfalls
Clear markup removes guesswork and can make pages eligible for enhanced results, although nothing is guaranteed. Typical errors include marking up content that is not visible, inventing ratings and letting business details drift out of step with other profiles.
How to validate
Test pages with Google's Rich Results Test and watch the enhancement reports in Search Console. Re-test after template changes, because a small edit to a theme can break markup across hundreds of pages without any visible difference on screen, and the errors then go unnoticed for weeks.
Next steps
Read structured data for small business websites, and consider our SEO and AI search service if you want markup implemented and monitored across a whole site rather than page by page.
