Schema markup validation checks before publishing FAQ or review pages

Reviewing Your Schema Markup Before the Page Goes Live

Before publishing a page, take a few minutes to review the structured data you’ve added. Even a small mistake in the schema can stop search engines from interpreting the page correctly, which means features like rich results may never appear. It is much easier to catch these issues before the page is live than to troubleshoot them after indexing has already started.

If you’re using schema types such as FAQPage or Review, compare your markup with the official documentation and make sure every required property has been included. Fields like mainEntity, acceptedAnswer, or itemReviewed are not optional for many schema types, so leaving one out or formatting it incorrectly can cause the markup to be ignored. Pay attention to spelling, property names, and the overall structure. Something as simple as a misplaced quotation mark or an incorrect value can prevent search engines from reading the data as intended.

Validating the Markup and Fixing Any Issues

Once everything looks complete, run the page through a schema validation tool before publishing. You can either enter the page URL if it’s already accessible or paste the source code directly into the validator. Within a few moments, the tool will highlight any problems it detects, making it much easier to spot missing fields, invalid property types, or formatting errors that are difficult to notice by reading the code yourself.

Not every message returned by the validator is a serious problem. Some are marked as warnings rather than errors, and understanding the difference can save unnecessary work. Errors usually indicate something that prevents the structured data from being processed correctly, while warnings often point out recommended fields that are missing. For example, a review schema may still be valid without an author property, but including it can make the structured data more complete and improve its eligibility for enhanced search features. Before publishing, review each message carefully and decide whether adding the suggested information will benefit the page rather than trying to eliminate every warning automatically.

Common Markup Mistakes to Catch Before Publishing

Frequently observed mismatches relate to missing required properties, incorrect property name spelling, and nested item type mismatches. A wrong field existing in published content requires checking the official schema documentation and correcting the property name or type.

Each mistake can prevent the markup from being read. Fixing these before publishing saves having to edit the page later and resubmit it for reindexing. Uncertainty about a specific property can be resolved by checking the official schema.org page for FAQPage or Review to confirm the allowed types and required fields.

Common Mistake	Where to Check	Next Action
Missing required property	Check the mainEntity list for FAQ or itemReviewed for review	Add the missing property with the correct value type
Incorrect property name spelling	Compare each property name against the official schema documentation	Correct the spelling to match the official property name exactly
Nested item type mismatch	Look at inner item types such as Question or Rating	Change the inner type to the correct schema type, such as Question for FAQ items

Verifying Markup After Publishing

After publishing the page and running a validation tool, checking the live page a day or two later is a good practice. Some validation tools let users test the live URL directly, showing exactly what search engines see when they crawl the page. Errors appearing on the live URL may indicate that a plugin, theme code, or caching system altered the markup after the page was saved. A passing live test with no rich results after a few weeks suggests the content may not meet the quality guidelines for that markup type.

FAQ pages should contain clear questions and answers that match the schema structure. Review pages should include genuine reviews with a rating and a clear subject. Keeping the markup accurate and the content relevant gives the page the best chance of displaying rich results in search listings.
