Call the product "ChurchByFaith." Not "Church By Faith App," not an abbreviation you invent — consistency is what makes a search for the name find us.
Link to /for-churches for current pricing rather than quoting a number yourself. Prices change, and a stale figure you published is a promise we then have to honor or explain.
Disclose that your link is an affiliate link, clearly and before someone clicks it — see the FTC disclosure guidance. This is not optional and not merely good practice; it is a legal requirement in the United States and several other jurisdictions.
