Schema markup is a bit of code you add to your website that tells search engines what your content actually means, not just what it says. It comes from a shared vocabulary at schema.org, and it is one of the more overlooked levers in technical SEO. Get it right and your listing can pick up star ratings, FAQ dropdowns, or product prices directly in the search results, which tends to make people click on you rather than the plain blue link below.
If you have ever searched for a recipe and seen a star rating, cooking time, and calorie count sitting under the page title, that is schema markup at work. Google is not reading your mind. It is reading a structured version of your content that you have handed it in a format it understands.
Why It Matters More Than It Looks
Search engines can read text fine on their own. What they struggle with is context. Is “Apple” a fruit or a company. Is that number on the page a price, a rating, or a phone number. Schema markup removes the guesswork by labelling these elements explicitly. Google has said for years that structured data does not directly boost rankings, but it does influence how your result appears, and appearance affects click through rate, which does eventually feed back into performance.
We saw this with a client running an ecommerce site. Their product pages had solid content but plain listings in search. Once we added Product schema with pricing and stock status, their click through rate improved within a few weeks, simply because their results looked more complete next to competitors who had not bothered. It is not glamorous work, but it compounds.
This sits firmly within the world of SEO services, and it is usually one of the first things worth checking during a technical SEO audit, alongside things covered in our guide to technical SEO for website health.
Common Types Of Schema Markup
There are hundreds of schema types listed on schema.org, but most websites only need a handful. Here is a quick summary of the ones you will use most often.
| Schema Type | What It Is For | Where You Will See The Result |
| Article | Blog posts and news content | Headline, publish date, author in search |
| Product | Ecommerce listings | Price, availability, star rating |
| LocalBusiness | Physical shops or offices | Address, opening hours, map pin |
| FAQPage | Question and answer content | Expandable questions under the result |
| Review | User or editorial reviews | Star ratings next to the listing |
| BreadcrumbList | Site navigation hierarchy | Breadcrumb trail instead of a URL |
If you run a shop with a physical location, pairing LocalBusiness schema with the kind of groundwork covered in our local SEO strategies guide tends to be worth doing together rather than separately.
How To Add It To Your Site
The recommended format is JSON-LD, a small script placed in the page header that does not touch your visible HTML. Most content management systems have a plugin for this now, so you rarely need to hand code it unless you are working on something bespoke. Once it is live, run the page through Google’s Rich Results Test to check it is being read correctly, and keep an eye on the Enhancements section inside Google Search Console, which will flag any errors.
Worth being honest here. Google has trimmed back which schema types actually produce visible rich results over the past couple of years. FAQ rich results, for instance, now only show for a narrow set of high authority sites. That does not mean skip the markup, it still helps with context and, increasingly, with how AI search tools interpret your pages, something we touched on in our piece about structured data and AI search. It means treat rich snippets as a possible bonus rather than a guarantee.
For a full breakdown of how this fits into broader on page and technical work, our SEO FAQs and our earlier piece on rich snippets and SEO are both worth a read.
For the official reference on syntax and supported types, Google’s own structured data documentation is the most reliable place to check, since schema requirements do shift.
Does This Fit Into A Wider Strategy
Schema markup on its own will not fix a site that has bigger problems. It works best as one part of a joined up approach that includes solid on page content, technical performance, and often PPC marketing to fill the gap while organic rankings build. If you are also running paid campaigns across Google Ads, LinkedIn advertising, or Facebook ads, structured data on your landing pages helps those visitors trust your site once they arrive, which tends to lower bounce rate.
FAQs
Does schema markup improve rankings directly?
Not directly. Google has been consistent that structured data is not a ranking factor on its own. What it does is improve how your listing looks, which can lift click through rate.
Do I need a developer to add schema markup?
Not always. Most CMS platforms, including WordPress via plugins, let you add common schema types without touching code. More complex or custom schema usually does need a developer.
Which schema type should I start with?
Start with whatever matches your page type. Article schema for blog content, Product for ecommerce, LocalBusiness if you have a physical location. Get the basics right before chasing the more niche types.
