Data Highlighter in Google Search Console lets you tag structured data visually without code changes. Useful for non-technical users, but implementing actual schema markup provides more control and reliability.
Understanding Data Highlighter in SEO
When Google understands your website content clearly, it can display rich snippets like reviews, event details, or product information in search results. But not every website owner knows how to work with structured data or schema markup. That’s where Google’s Data Highlighter comes in.
It’s a simple point-and-click tool that allows you to highlight parts of your web pages (like product names, prices, or event dates) so Google can interpret the data correctly. While it doesn’t replace schema markup, it provides an easy way to test and add structure to your content for better visibility in search.
How Data Highlighter Works Across CMS Platforms
WordPress
For small sites using themes or plugins, Data Highlighter is a quick way to tag posts and products if schema isn’t already added through plugins like Yoast or Rank Math.
Shopify
Shopify stores often rely on structured product data for reviews and pricing. Data Highlighter helps fill gaps if schema markup is incomplete.
Wix
Since Wix websites are beginner-friendly, Data Highlighter works as a bridge for site owners who don’t edit code.
Webflow
For visually designed sites, Data Highlighter can identify key sections for better indexing and snippet generation.
Custom CMS
Enterprise-level CMS platforms may not have built-in schema tools. Data Highlighter helps speed up tagging without a developer.
