15 free embeddable widgets

Put a free SEO tool on your site

Add a genuinely useful tool for your visitors — an instant SEO & AI-readiness checker, a security scan, a meta-tag preview and more. It’s free, we host and keep it current, and it takes one line of HTML. Pick a widget below and copy its snippet.

Genuinely useful — free

Give your readers a real interactive tool, not another ad. No cost to you or them, ever.

Zero maintenance

We host and update it. Your embedded tool always runs the latest checks — you never touch it again.

One line of HTML

Copy the snippet, paste it into any page or CMS block. Works in WordPress, Webflow, Ghost, plain HTML — anywhere an iframe runs.

Live demo — this is exactly what your visitors see

Pick your widget

All 15 widgets, ready to paste. Each snippet includes a small, unobtrusive credit line linking back here — that’s all we ask in return. Copy, paste, done.

How it works

1. Copy a widget’s embed code above.
2. Paste it into any page, post, or CMS HTML block. Adjust the height if you like.
3. Keep the one-line credit — it links back so others can find the tool. That’s it.
