Google doesn't have a fixed word-count requirement, but content depth strongly correlates with rankings on competitive queries. The average top-10 result for informational queries is 1,500-2,500 words. The Word Counter and Reading Time tools tell you instantly if you're below the threshold. Headline Analyzer helps you craft a clickable title — and on most pages, the title is responsible for 50%+ of click-through-rate variance.
Markdown is the publishing format that won
Markdown is the universal writing format: it's plain text, version-control-friendly, renders consistently across platforms, and converts to HTML cleanly. Most CMSes (Ghost, Notion, GitHub, every static site generator) prefer it. The Markdown-to-HTML and HTML-to-Markdown tools handle the conversion in either direction. Use them to migrate between platforms, paste rich content into Markdown-only editors, or strip HTML noise out of copied web content.
Social media character limits cheat sheet
Twitter/X: 280 chars (URLs count as 23). Instagram: 2,200 caption + 30 hashtags max, but only first 125 chars show in feed. LinkedIn: 3,000-char posts, but engagement drops sharply over 1,300. Facebook: 63,206 chars allowed but the algorithm punishes posts over 80 chars. Bluesky: 300 chars. Mastodon: 500 chars default, 4,000 on some instances. The Twitter Counter and Instagram Caption Counter on this page enforce the right limits for each platform.
