Meta tags are HTML elements placed in a page's <head> section that provide metadata about the page to search engines and social platforms. Key meta tags include the title tag, meta description, Open Graph tags (for Facebook/LinkedIn), and Twitter Card tags. Well-crafted meta tags improve click-through rates from search results, control how your pages appear when shared on social media, and help search engines understand your content — all of which contribute to better SEO performance.
Open Graph (OG) is a protocol originally created by Facebook that allows you to control how your web pages appear when shared on social media platforms. By adding OG meta tags (og:title, og:description, og:image, og:url) to your HTML, you define the title, description, and image that appear in social cards on Facebook, LinkedIn, WhatsApp, and other platforms. Without OG tags, platforms guess what to show — often with poor results. Twitter uses a similar system called Twitter Cards with its own set of meta tags.
A URL slug is the part of a URL that identifies a specific page in a human-readable form, typically appearing after the domain name (e.g., /seo-friendly-url-slug). For best SEO practices, slugs should be lowercase, use hyphens to separate words, be concise and descriptive, include relevant keywords, and avoid special characters, spaces, or unnecessary words like "and", "the", or "a". A clean, descriptive slug helps both search engines and users understand what a page is about before clicking.
