Show different content, offers, or layouts to visitors based on their location, behavior, or traffic source.
Personalization software changes what visitors see based on audience, behavior, context, or commerce data. The big dividing lines are how audiences are built, whether personalization can be evaluated against a control, and whether the product is designed for general websites or ecommerce merchandising.

Controlled audience experiences
#1 of 6 in Personalization
Optimizely Personalization swaps images, headlines and promotions based on a visitor's on-site behavior or journey stage, and can recommend content, products or offers. It also handles geo-targeting with localized content, currency and language, and lets teams test a personalized experience to prove its impact before rolling it out to everyone.
Funnel-based targeting
#2 of 6 in Personalization
ConvertFlow combines website personalization with popups, forms, quizzes, landing pages, and funnel building. It is a fit when personalization is closely tied to lead capture or ecommerce journeys and is not treated as a stand-alone experimentation program; its campaign builder keeps targeting close to the conversion element itself.
Onsite campaign personalization
#3 of 6 in Personalization
OptiMonk covers onsite personalization through popups, embedded campaigns, dynamic content, recommendations, and A/B testing. Choose it when you want to change messaging or offers on-site without adopting a larger digital-experience stack. Campaigns can be adjusted without rebuilding the underlying site experience.
For experimentation-led personalization
#4 of 6 in Personalization
Wingify’s VWO offering combines experimentation with personalization, so teams can create targeted experiences and evaluate variants without treating personalization as a one-way content change.
For ecommerce merchandising
#6 of 6 in Personalization
Nosto centers personalization on ecommerce, using shopper behavior and commerce data across product recommendations, personalized search, merchandising, and other storefront experiences. Teams can use high-intent search and browsing signals to adapt what products or content a shopper sees. The product is therefore closely tied to storefront merchandising decisions.
