Put the Best Card widget on your site

Your readers pick the cards they carry and what they're buying. The widget shows which card earns the most, with the math behind it. Free, one iframe tag, no bank login or card numbers.

1. Copy the snippet

<iframe
  src="https://card-savvy.com/embed/best-card?ref=YOURSITE"
  width="100%"
  height="760"
  style="border:0;border-radius:12px"
  title="Best Card for This Purchase — CardSavvy"
  loading="lazy"
></iframe>

Replace YOURSITE with your domain. It doesn't change anything for your readers; it lets both of us see the widget is being used on your site.

2. Size it

The widget is responsive down to 320px wide. width="100%" with a fixed height works in any article column:

760px height fits most uses (wallet + purchase form + result).
Going taller (900px) avoids inner scrolling for readers with many cards.
The "Powered by CardSavvy" attribution footer is built in.

Questions publishers ask

Is it free?

Yes. There is no fee, no contract, and no affiliate arrangement behind it. CardSavvy currently earns nothing from the widget; we build readership and the tool builds yours.

Does it collect my readers’ data?

Readers type card names, never card numbers, and there is no bank login. The wallet they build stays in their own browser (localStorage). We collect standard anonymous usage analytics so we know the widget is working.

Can I customize it?

Not yet. The widget ships with CardSavvy styling and a small attribution footer. If you need a specific category preset, sizing, or theming, email us what you need and we’ll consider it.

Need something else?

Custom categories, a different default view, or a question about how the math works: email us and a human answers.
