Guide: Structured Data for eCommerce SEO
This technical guide explains how structured data (schema markup) helps search engines, shopping platforms and AI systems understand eCommerce pages. It defines structured data vs. unstructured content, describes common schema.org types (Product, Offer, AggregateRating, ProductGroup, Organization, BreadcrumbList, WebSite, FAQPage), and recommends JSON-LD as the preferred format. The article stresses that schema clarifies facts (price, availability, GTIN, reviews) but is not a magic ranking shortcut, and outlines implementation best practices: keep markup truthful and visible, prefer server-rendered JSON-LD for fast-changing data, validate with Rich Results Test and Search Console, avoid duplicate or conflicting schema, and treat schema as part of broader SEO, feeds and content strategy. It also notes Google reduced FAQ rich-result visibility (2023 and further signals in 2026) and provides practical checklists by page type and testing/measurement advice. Publication date: 2026-05-09.
AI-Targeted Schema Markup Boosts Citation Visibility
This technical guide explains that most sites implement schema markup optimized for Google, which differs from the types and fields AI engines (ChatGPT, Perplexity, Gemini, Google AI Overviews) prioritize for citation. It identifies Article, FAQPage, Organization, Product, HowTo and Dataset schema as most valuable for AI citation, while Generic LocalBusiness, VideoObject without transcripts and Event schema are often de‑prioritized. The article recommends using JSON-LD placed in the HTML head, including author and recency fields, validating schema regularly, avoiding schema spam, and measuring citation changes across engines. It also outlines engine-specific preferences (e.g., Perplexity favors primary sources and datasets; Gemini favors Knowledge Graph alignment) and speculates on emerging schema types such as citation/evidence/AI-content schemas and dedicated AI schema validators.
US Government Excludes Microsoft from Visa Program
The US government has barred Microsoft from participating in the permanent residency process for foreign workers with H-1B visas, accusing the company of abusing the program. Vice President JD Vance stated that Microsoft laid off 6,000 American employees last year while benefiting from 6,300 H-1B visa holders. The Department of Labor, led by Keith Sonderling, will not accept new permanent residency applications from Microsoft, as well as several consulting firms and Adobe. This action comes weeks before the midterm elections and reflects the Trump administration's broader criticism of the H-1B program, which it claims disadvantages American workers. Microsoft has not yet responded. The move could impact the tech industry's ability to retain skilled foreign talent.
