Most foundry service pages rank poorly for local and industry searches because they skip structured data entirely—leaving money on the table while competitors capture qualified leads. Schema markup tells search engines exactly what your foundry does, your service areas, certifications, and turnaround times, which directly improves your visibility to buyers searching for casting vendors. Without it, you're invisible to both algorithms and the technical procurement teams that rely on search to vet suppliers.
Why Schema Markup Matters for Foundries
Search engines like Google reward pages with structured data because it removes ambiguity. When you specify that your business offers investment casting, sand casting, or permanent mold casting—with exact lead times and certifications (ISO 9001, AS9100, etc.)—the algorithm understands your niche expertise. This becomes crucial in manufacturing, where buyers run specific technical searches and expect to see verified capabilities immediately.
Schema markup also unlocks rich snippets. Instead of a plain blue link, your foundry's page can display your certifications, lead time ranges, service areas, and customer ratings directly in search results. This extra real estate increases click-through rates by 20–30% compared to plain listings.
Core Schema Types for Casting & Foundry Services
LocalBusiness schema is your foundation. This tells Google your business name, address, phone number, and operating hours. Add a serviceArea property specifying your geographic reach—whether you serve a 50-mile radius, multiple states, or clients nationally.
Service schema is where you detail what you actually do. Create separate Service entries for each major offering:
- Sand casting (ferrous and non-ferrous)
- Investment casting
- Die casting
- Permanent mold casting
- CNC machining and finishing
- Quality testing (X-ray, tensile testing, pressure testing)
For each service, include realistic turnaround times (e.g., "3–5 business days for sand castings up to 50 lbs") and cost ranges if applicable (e.g., "$800–$3,500 depending on complexity and material").
Organization schema highlights your certifications, team size, and years in business. This builds trust with procurement managers who need to verify vendor stability.
Review schema (assuming you have them) shows star ratings and customer testimonials. A foundry with 4.7-star reviews displaying in search results converts significantly better than one without.
Step-by-Step Implementation
1. Audit your current pages. Use Google's Rich Results Test (search.google.com/test/rich-results) to check whether your site currently outputs any schema. Most foundry websites output nothing.
2. Add LocalBusiness markup. Include your business name, exact address, phone, email, and a serviceArea polygon or radius. If you operate multiple locations, add separate LocalBusiness entries for each.
3. Create Service markup for your core offerings. Specify material types (aluminum, stainless steel, ductile iron, bronze), weight ranges, tolerance capabilities, and lead times. Buyers search for "aluminum casting 5–10 lb parts" or "investment casting aerospace," so be granular.
4. Include certifications. Add sameAs links to your ISO certificate pages or third-party verification (AS9100, NADCAP, API, etc.). This signals authority to both algorithms and human buyers.
5. Test and deploy. Use Google's test tool and Bing's markup validator to ensure clean output before publishing. Deploy to your live site, then request re-indexing via Google Search Console.
6. Monitor performance. Check Search Console monthly for impressions and click-through rates on your main service pages. If clicks are low, refine your service descriptions or add FAQ schema.
Common Mistakes Foundries Make
Don't vague-post your services. "Metal casting" is useless; specify "precision sand casting for automotive engine blocks, 5–50 lb range, ISO 9001 certified, 4–6 week lead time."
Avoid outdated lead times or pricing. If your schema says "2-week turnaround" but you actually need 4 weeks, buyers will contact you and waste both parties' time.
Skip certifications if you have them. Buyers in aerospace, automotive, and medical device sectors require verified certifications. Schema is your chance to broadcast them at scale.
Don't forget your service areas. A regional foundry that serves only the Midwest shouldn't claim national service. Be honest; local specificity ranks better anyway.
Getting Found and Winning Leads
Listing your foundry services on platforms like Mercoly—which aggregate verified manufacturers and automatically populate your certifications, capabilities, and lead times—accelerates discovery and supplements your organic SEO efforts. Buyers searching for "foundry near me" or "investment casting supplier" find verified, schema-enabled listings first.
Frequently Asked Questions
Q: Do I need schema markup if I'm a small foundry just starting out? Yes. Schema helps smaller foundries compete by making their capabilities visible in search results; you're signaling to Google that you're a legitimate business, which costs nothing and takes a few hours to implement.
Q: What's the difference between Service schema and Product schema for castings? Service schema describes what you do (the casting process and capabilities); Product schema describes finished goods you sell off-the-shelf. Most foundries use Service schema, but if you sell standard casting blanks, use both.
Q: How long does it take to see results from schema markup? Typically 2–4 weeks after Google re-crawls your pages; you may see schema-enabled rich snippets appear in search results within 4–8 weeks if your content ranks on the first or second page already.
