Schema Markup

Schema Markup is structured code that you add to your website's HTML to help search engines like Google better interpret your content. It uses a standardised vocabulary from schema.org to label information about products, services, events, reviews or organisations. This allows Google to show richer search results with stars, prices, opening hours or FAQ answers directly in the SERP. For SMEs, this means more visibility and higher clickthrough rates without an extra advertising budget.

How Schema Markup works technically

Schema Markup you add in JSON-LD format, a script block in the head or body of your page. Google reads this script and recognises, for example, that a block of text is a product with a price, stock status and average rating. You don't need to modify the visible content. The markup works as metadata running parallel to your HTML. Tools like the Google Rich Results Test show whether your markup is correct. Most CMS systems and SEO plugins generate basic schema automatically, but for specific applications you often write manually or via a schema generator.

Why Schema Markup came into being and why it is becoming even more important now

Schema.org werd in 2011 gelanceerd door Google, Bing, Yahoo en Yandex om een gemeenschappelijke taal voor gestructureerde data te creëren. Voor die tijd probeerde elke zoekmachine content te raden uit ongestructureerde HTML. Dat leidde tot inconsistente en vaak foutieve interpretaties. Met de opkomst van voice search, AI-assistenten en generatieve zoekervaringen wordt gestructureerde data nóg belangrijker. Google gebruikt schema om featured snippets, knowledge panels en product carousels te vullen. Bedrijven zonder schema missen kansen in deze rijkere zoekformaten.

What Schema Markup brings to Dutch SMEs

Een webshop die ProductSchema toevoegt ziet vaak een stijging in klikfrequentie van 10 tot 30 procent, omdat sterren en prijzen direct in de zoekresultaten verschijnen. Een lokaal bedrijf met LocalBusinessSchema krijgt openingstijden, adres en telefoonnummer prominent in Google Maps en lokale zoekresultaten. FAQ-schema zorgt dat je antwoorden uitklappen in de SERP, wat ruimte inneemt van concurrenten. In de praktijk merken we bij MKB-klanten dat schema vooral werkt als de rest van je SEO-basis op orde is. Schema compenseert geen slechte content, maar versterkt goede content met betere presentatie. Het is een technische SEO-hefboom die je combineert met sterke on-page optimalisatie en relevante interne linkstructuur.

Schema Markup has dozens of variants, each designed for a specific content type. The choice depends on what you offer and what information you want to highlight in search results. Below are four common applications that give SMEs immediate results, plus a decision framework on when schema makes sense or not.

ProductSchema for online shops and offer pages

Add ProductSchema to product pages to pass price, stock status, brand and reviews to Google in a structured way. This leads to product rich snippets with stars, prices and availability directly visible in search results. An online shop with 500 products that adds schema often sees a 15 to 25 per cent click-frequency increase on product pages. It also works for B2B service providers offering specific services or packages with fixed prices. Note: Google only shows rich snippets if your markup is correct and your page has sufficient authority. Check this with the Rich Results Test before setting expectations.

LocalBusinessScheme for regional visibility

LocalBusinessSchema you use if you have a physical location that customers come to or if you operate in a specific region. You mark address, opening hours, phone number, service area and business type. Google shows this information in Maps, the knowledge panel and local search results. A dental practice in London or a catering establishment in Utrecht benefits immediately. With SME clients, we see that correct LocalBusinessSchema often makes the difference between appearing in the local 3-pack or not. Combine this with a well-maintained Google Business Profile for maximum impact.

FAQScheme for frequently asked questions in the SERP

FAQSchema add to pages with frequently asked questions. Google can then unfold these questions in search results, allowing your answer to take up more space and push competitors down. This works well for knowledge base pages, product explanations or services where customers have a lot of questions beforehand. A B2B service provider with 12 employees providing complex services often sees that FAQ scheme helps build trust before the first contact. Note that Google displays FAQ-rich results selectively. Make sure your questions are really relevant and answers concrete, otherwise Google will ignore your markup.

ArticleSchedule for blog and news content

ArticleSchema you use for blog articles, news items or knowledge base pages. You mark author, publication date, main image and organisation. This helps Google categorise your content and include it in news carousels or Discover feeds. For content marketing and SEO strategies, this is a standard addition. It does not provide a direct rich snippet like ProductSchema, but it does increase the chances of Google rating your content as trustworthy and up-to-date. Combine ArticleSchema with a clear author page and regular updates to build authority.

When Schema Markup is the right choice and when it is not

Schema Markup works if your content is good and your technical SEO is in order. It does not compensate for poor text, slow load times or poor accessibility. Add schema if you already have ranking on page 1 or 2 and want to increase your click rate. Not useful: add schema to thin pages with no value, or to pages that do not yet index. Also not useful: use schema to show misleading information, such as fake reviews. Google penalises this. Start with schema types that directly match your most important pages and measure the effect in Google Search Console before rolling out further.
