Schema markup is structured data added to a page that tells search engines exactly what the page is about, such as a business, an article, a product or an FAQ. It can make pages eligible for rich results and helps machines understand facts, but it does not by itself guarantee rankings or AI mentions.

Types that matter most for businesses
| Schema type | Use |
|---|---|
| Organization / LocalBusiness | Name, address, contact, hours |
| Article | Author, date, publisher |
| FAQPage | Questions and answers on a page |
| BreadcrumbList | Site structure |
| Product / Service | Offerings and details |
Common misconceptions
Markup that describes content not visible on the page can violate Google's guidelines. More markup is not better; accurate markup is.
Our expert view
We treat schema as a translation layer: it should say, in machine-readable form, exactly what the page already says to people. Every Unitrux article, including this one, carries Article, FAQ and breadcrumb markup.

Limits and honest expectations
Search engines and AI assistants change their answers over time and no one controls them. Results vary by industry, city and competition, and we do not guarantee a position, a mention or a number of leads. We report what is measurable, plainly.
