Notes & Tips

  • • Aim for Reading Ease 60–70 for wide audiences; lower grades are easier.
  • • Keep 1 H1 per page; use H2/H3 for sections. Avoid heading-only pages.
  • • Minimize ALL-CAPS and excessive emojis; they can hurt CTR or look spammy.
  • • Titles/descriptions are sized in pixels, not characters—use this tool to avoid truncation.
  • • Everything runs locally in your browser. No content is uploaded.
We honestly need your help

Most people will use these tools for free and never think about how much it costs to keep them online. That’s okay — we built Postly to help. But if our tools have saved you hours of work, helped you get better reach, or made client work easier, please pause for a moment and consider supporting us. Even a small contribution genuinely helps keep Postly alive, maintained, and improving. We are a tiny team, not a big company. We pay real infrastructure bills every month to keep this running. If you can, please be one of the few people who chooses to help.

Hosting, builds & background jobs aren’t free.
APIs, AI, and storage all scale with you.
Every feature is custom-built, not white-label.
Please Support Postly

If you’re not in a position to support us, that’s okay. Postly will still be here for you. But if you are one of the few who can chip in, your support directly keeps these tools online for everyone else.
