Structured Data (Schema Markup)
Structured data is a block of code on a web page that labels its contents, such as a price, opening hours or a review, using the shared vocabulary at schema.org, so search engines can read them without guessing.
What it means
A web page is written for people. A search engine has to guess that "₹1,850" is a price, that "Mon to Sat, 9 to 8" is opening hours and that "4.6" is a rating. Structured data removes the guessing. It is a small block of code, usually in a format called JSON-LD, that labels these facts using the shared vocabulary at schema.org. Visitors never see it, but Google, Bing and other crawlers read it.
What to expect from it
Correct markup can make a page eligible for rich results: price and stock beside a product, event dates, breadcrumb trails, business details. Eligible is not guaranteed, and Google decides case by case. It also expects the markup to match what is visible on the page. Labelling reviews that no visitor can see, or a price that differs from the real one, breaks Google's guidelines and can cost you rich results altogether.
Be wary of anyone selling FAQ markup as a quick win. Google narrowed FAQ rich results in 2023 to a short list of authoritative sites, so an ordinary business should not expect expandable questions under its listing. And structured data is not a ranking boost on its own; its job is to help Google understand a page and to make the listing more informative.
An example from Karur
A home-textile brand in Karur sells towels, bedsheets and curtains through its own online store. Each product page shows a name, photographs, sizes, price, stock status and customer reviews. With Product markup, those same facts are also written in a form Google can read, so a search for that bedsheet can show the price and availability beside the result. A competitor selling a similar bedsheet without the markup gets a plainer listing, and fewer clicks.
How we use it
At VS Tech Builders, structured data belongs in the page templates rather than being an extra: business details on corporate websites, product and price information on every page of an online store, article details on blog posts, breadcrumbs throughout. Whoever builds your site should check it with Google's free Rich Results Test before launch, and you should ask to see the result. Our e-commerce SEO guide shows where it sits among the other basics, and SEO and XML sitemap cover its neighbours.
Common questions
Will structured data improve my Google ranking?
Not directly. Structured data is not a ranking boost on its own. What it can do is make a listing eligible for a richer display, such as price, availability or event dates, and that can bring more clicks from the same position. It also helps search engines understand a page correctly, which matters most for products, local businesses and events.
How do I check whether my website already has structured data?
Paste a page address into Google's Rich Results Test or the Schema Markup Validator, both free. They list every type of markup found and flag errors. Google Search Console also reports problems across your whole site once enough pages have been crawled. If the tools find nothing, the page has none, which is common on older sites that were built without search in mind.
