Meta Tags: The Foundation of SEO
Meta tags tell search engines what your page is about. The most important are: title (30‑60 characters), meta description (50‑160 characters), and canonical URL to prevent duplicate content. Use Open Graph tags for social sharing and Twitter Cards for Twitter. OffURL checks for all these tags and flags missing ones.
Structured Data with JSON‑LD
JSON‑LD (JavaScript Object Notation for Linked Data) helps search engines understand your content. Common types include: Article, Product, Review, FAQ, HowTo, and Organization. Adding schema markup can lead to rich snippets in search results, increasing click‑through rates. OffURL validates your JSON‑LD for syntax and correctness.
Page Speed and Core Web Vitals
Google uses page speed as a ranking factor. Optimize images (WebP, compression), use caching (Cache‑Control headers), enable GZIP/Brotli compression, and minimize JavaScript. Use a CDN to deliver content faster. OffURL measures your page load time, TTFB, and checks for compression and caching.
Mobile Optimization and Accessibility
Google uses mobile‑first indexing, so your site must be mobile‑friendly. Use responsive design, ensure text is readable without zooming, and buttons are easily tappable. Accessibility (WCAG) also affects SEO – use semantic HTML, alt text for images, and proper heading hierarchy.
