Continuity refers to making sure that each step in the conversion process, whether it's asking for information, getting users to click another link, or sign up
for a newsletter, either states or supports the PPC ad message (or value proposition).
Congruence is the idea that every element of the landing page, from the text, to the images, to
the logo and overall design, also supports that value proposition.
Using one week-long test, MarketingExperiments was able to show that subtle tweaks like editing headline and body copy for
continuity led to a 63% increase in conversions. For congruence, a 24-day test showed that the use of specific images and color schemes cause a 54% increase in conversions. And both tests proved that
the site changes didn't have to be radical, time-consuming or costly.
