Meta tags live in the <head> section of your HTML and tell search engines and social media platforms what your page is about. The right meta tags improve your click-through rate from Google search results and ensure your pages look great when shared on Facebook, Twitter and LinkedIn.
The Three Types of Meta Tags You Need
SEO meta tags: tell Google your page title and description. These appear directly in search results. Open Graph tags: control how your page looks when shared on Facebook and LinkedIn (og:title, og:description, og:image). Twitter Card tags: control the preview card when your URL is shared on Twitter/X. Without these, social platforms guess — often badly.

Writing a Good Meta Title and Description
Meta title: 50–60 characters. Include your primary keyword near the start. Be specific and descriptive. Avoid keyword stuffing. Example: "Online PDF Compressor — Reduce PDF Size to 100KB Free". Meta description: 150–160 characters. Summarise what the user gets. Include a call to action. Example: "Compress any PDF to 100KB, 200KB or any size in seconds. No sign-up, no watermarks. Works on mobile."
The Open Graph Image — What Size Works Best?
For Open Graph (Facebook, LinkedIn): 1200×630 pixels (1.91:1 ratio). For Twitter large image card: 1200×628 pixels. Minimum: 600×315 pixels. File size: under 8MB, ideally under 1MB. Format: JPG or PNG. Having a great OG image can dramatically increase clicks when your content is shared on social media.
Frequently Asked Questions
Do meta keywords still affect SEO?
No. Google has ignored the meta keywords tag since 2009. Focus on title, description, and on-page content quality instead.
What happens if I do not add Open Graph tags?
Social platforms will try to extract a title and description from your page content — often picking the wrong text or no image. Always add OG tags for control over how your content appears.
How do I test my Open Graph tags?
Use the Facebook Debugger (developers.facebook.com/tools/debug), the Twitter Card Validator, or LinkedIn Post Inspector to preview exactly how your page looks when shared.
Does the canonical tag affect SEO?
Yes. The canonical tag (rel="canonical") tells Google which version of a URL is the "official" one. Important for preventing duplicate content issues with URLs that have parameters.
