Conversion Rate Optimization (CRO)

The definition

Conversion Rate Optimization (CRO) is the practice of systematically increasing the percentage of website visitors who complete a desired action — such as submitting a form, calling, or making a purchase — through testing and design improvements.

In short

  • The conversion rate is conversions divided by total visitors, expressed as a percentage.
  • CRO improves results from existing traffic, so it compounds the value of SEO and ads.
  • It relies on evidence — analytics, user behaviour, and A/B testing — rather than guesswork.
  • Common levers include clearer calls to action, faster pages, stronger trust signals, and simpler forms.

How it applies to Calgary businesses

A Calgary business can rank well and still lose money if visitors arrive and leave without acting. CRO closes that gap: it turns more of the traffic your SEO and ads already earn into calls, booked jobs, and sales — often the cheapest growth available, because you are not paying for more visitors, just converting more of the ones you have. Clear CTAs, fast mobile pages, and visible trust signals usually move the needle first.
