A Content Delivery Network serves static assets from edge locations close to the user, reducing latency, improving cache hit rates, and offloading traffic from the origin server. Fixing this issue means routing your images, JavaScript, CSS, and fonts through a CDN so visitors anywhere in the world get fast, consistent delivery.

Where to make the change

• Cloud platforms: Cloudflare, Fastly, AWS CloudFront, Bunny.net, and similar providers offer free or low-cost CDN tiers. Sign up, point your domain through the CDN, and enable caching for static asset paths.
• WordPress: use a CDN integration plugin or sign up directly with Cloudflare and update the site's nameservers.
• Shopify: Shopify serves storefront assets through its own CDN automatically; the failure usually points at custom assets uploaded outside the platform.
• Headless or framework sites: deploying to Vercel, Netlify, or Cloudflare Pages puts the entire site behind a global CDN by default.

Common causes and how to resolve them

• No CDN at all: add one. Even a free Cloudflare account in front of an existing host produces measurable speed gains.
• CDN configured but bypassed for some assets: ensure all img, script, link, and font URLs use the CDN hostname rather than the origin.
• Cache headers prevent caching: long-lived assets need cache-control headers like public, max-age=31536000, immutable. Without them, the CDN cannot cache effectively.
• Origin-only third-party scripts: many vendors already serve their scripts via their own CDN. Use the URL the vendor provides rather than self-hosting.

Best practices

• Use a versioned asset path: filenames like app.a3f9.css let you set far-future cache headers without ever serving stale files. Update the filename when content changes.
• Enable Brotli at the edge: most CDNs can compress responses on the fly, including text formats.
• Pre-warm caches for new launches: after a major release, request key URLs through every region (or use the CDN's purge-and-prefetch tools) so users do not hit cold caches.

Structured data is a standardized way to label the entities and relationships on a page so search engines and AI answer engines can understand them. Adding the right schema helps unlock rich result features in SERPs (star ratings, FAQs, product cards, recipes, events) and gives AI answer engines precise facts to extract when generating responses. Fixing this issue means picking the schema types that match your content and embedding them as JSON-LD inside the page <head>. See the Google Search Central structured data guide for the full type catalog.

Example

<script type="application/ld+json">
{
  "@context": "https://schema.org",
  "@type": "Article",
  "headline": "How to choose marathon running shoes",
  "author": { "@type": "Person", "name": "Jane Doe" },
  "datePublished": "2026-04-15",
  "image": "https://example.com/images/hero.jpg"
}
</script>

Where to make the change

• Raw HTML: embed a JSON-LD block inside the <head>. JSON-LD is Google's preferred format because it does not interleave with visible content.
• WordPress: a dedicated SEO plugin generates JSON-LD for articles, products, breadcrumbs, and FAQ blocks automatically. Customize the templates for non-standard content.
• Shopify: Shopify themes emit Product schema by default. Extend with custom types via theme code edits.
• Wix or Squarespace: built-in blocks for FAQ, recipe, and event content emit schema automatically.
• Headless or framework sites: generate JSON-LD from your content data in the layout component so every page ships consistent schema.

Common causes and how to resolve them

• No structured data at all: add at minimum the @type that matches the page (Article for blog posts, Product for product pages, Organization for the homepage).
• Wrong schema type for the content: using Product schema on an article page misleads search engines. Pick the type that matches what the page actually is.
• Required properties missing: each schema type has required fields. Validate with the Rich Results Test to surface missing properties.
• Markup does not match visible content: Google penalizes structured data that asserts facts the page does not show. Reflect what is actually on the page.
• Multiple conflicting blocks: a theme and an SEO plugin both emit schema for the same entity. Pick one source of truth.

Best practices

• Validate before shipping: Google's Rich Results Test and Schema Markup Validator catch syntax errors and missing required fields.
• Use JSON-LD: easier to maintain than Microdata or RDFa and Google's preferred format.
• Cover the obvious wins: Article, Product, BreadcrumbList, Organization, and FAQPage are the highest-impact types for most sites.
• Keep schema accurate: wrong or exaggerated schema can lead to Google removing rich result eligibility for the entire site.
