The invisible layer that determines whether AI finds you
Your career page looks perfect. Beautiful photos, strong copy, clear CTAs. But under the bonnet? Chaos. No structured data. No schema markup. To an LLM, your page is a wall of text with no context.
This is the difference between being found and being ignored.
What is schema markup?
Schema markup is standardised code that helps search engines and AI systems understand your content. It is the translation layer between human content and machine interpretation.
Without schedule: “We offer 25 holidays”
With schedule: { "@type": "JobPosting", "jobBenefits": "25 holidays"}
The difference? AI systems can directly categorise, compare, and cite the second variant.
The impact in figures
Research shows consistent benefits of schedule implementation:
- Getting websites with schema markup 40% more clicks in search results (Milestone Research, 2024)
- Scheme adoption by enterprises increased by 35% between 2023-2025
- Pages with FAQ schedule become 2.3x more often quoted by LLMs
- JobPosting scheme increases job visibility with 25% in Google for Jobs
Essential schema types for employer branding
| Schedule type | Application | Impact |
|---|---|---|
| Organisation | Company information, logo, social links | Basic recognition as an entity |
| JobPosting | Vacancies with salary, location, requirements | Visibility in job aggregators |
| FAQPage | Frequently asked questions candidates | Direct answer matching in AI |
| Article | Blog posts, thought leadership | Author authority and freshness |
| Person | Leadership team, employee spotlights | Expertise signals for E-E-A-T |
| Review/AggregateRating | Employer reviews | Social proof in search results |
Implementation: step by step
Step 1: Audit your current situation
Use Google's Rich Results Test or Schema.org's validator to check which schemas you already have (probably: few to none).
Step 2: Start with Organization schedule
This is your foundation. Without Organization schema, AI is not even sure who you are.
Minimum take-up:
- Official company name
- Logo URL
- Founding date
- Number of employees
- Industry/sector
- Social media profiles
Step 3: Implement JobPosting scheme for all vacancies
Google requires this for Google for Jobs. LLMs use it to extract vacancy information.
Mandatory fields:
- Title, description, date posted
- Hiring organisation
- Location (or “remote”)
- Salary indication (increasingly important)
Step 4: Add FAQPage schedule to your career page
This is where the magic happens for GEO. FAQ schedule directly matches how candidates ask questions of LLMs.
Step 5: Validate and monitor
Schema errors can hurt your visibility. Test regularly with Google Search Console.
Common mistakes
- Incomplete schedules. Half implementations are sometimes worse than no implementation
- Outdated information. Schemas that do not match page content are penalised
- Missing @id. Without unique identifiers, AIs cannot link entities
- No nesting. Organisation → JobPosting relationships must be explicit
Beyond schedule: other technical optimisations
Page speed
LLMs with web access (Perplexity, ChatGPT Browse) have timeouts. Slow pages are skipped.
- Target: <3 seconds loading time
- Optimise Core Web Vitals
Mobile-first
Google's crawler is mobile-first. What doesn't work on mobile doesn't exist for AI.
Crawlability
Check your robots.txt. Are you accidentally blocking important pages from crawlers?
XML sitemap
An up-to-date sitemap helps AI systems understand your content structure.
The ROI of technical optimisation
Technical GEO optimisation is a one-off investment with ongoing returns:
- Implementation time: 2-4 weeks for basic diagrams
- Maintenance: 2-4 hours/month
- Expected impact: 20-40% improvement in AI visibility within 3-6 months
