Which website builders can I add the button to, and do I need a paid plan?

There are one-screen steps for Wix, Squarespace, WordPress, GoDaddy, Google Sites, Weebly or Square Online, a Facebook page, Google Business Profile, and for having no website at all. Wix and Google Sites let you place the button code or the form on a free plan. Classic Weebly also accepts embed code on its free plan; Square Online embeds need Plus or Premium. WordPress.com embeds need a paid plan with hosting features activated. Some builders restrict embeds by plan, so the steps also show an ordinary button that opens your link. Facebook and Google Business Profile take your link rather than code.
