SEO Meta Tags: Everything You Need to Know
Title Tags and Meta Descriptions
The title tag is the single most important on-page SEO element. It appears in search results, browser tabs, and social media shares. Keep it under 60 characters and front-load your primary keyword. The meta description (under 160 characters) doesn't directly affect rankings but heavily influences click-through rates. Write compelling descriptions that make searchers want to click.
Open Graph and Twitter Cards
Open Graph tags control how your pages appear when shared on Facebook, LinkedIn, and other social platforms. Twitter Cards do the same for Twitter/X. At minimum, set `og:title`, `og:description`, `og:image`, and `og:url`. Use high-quality images (1200×630 for OG, 1200×600 for Twitter summary_large_image) for maximum visual impact.
Structured Data with Schema.org
Beyond meta tags, structured data helps search engines understand your content at a deeper level. Use Article schema for blog posts, FAQ schema for Q&A pages, and Product schema for e-commerce. FreeSEOKit generates all major schema types with proper JSON-LD formatting.
Common Meta Tag Mistakes
Duplicate title tags across multiple pages confuse search engines. Missing meta descriptions mean Google generates its own (often poorly). Keyword-stuffed titles look spammy and get lower click-through rates. Not setting Open Graph images means social shares use a random image from your page — or worse, no image at all.
