Build campaigns

Optimizely Personalization lets you build personalized experiences for your site visitors called campaigns. The following resources will help you build and manage your personalization campaigns.

• Set up a page – Pages are URL patterns that tell Optimizely where to run campaigns on your site. Use them as templates or for a single campaign.
• Custom events – Create custom events to track behaviors that cannot be measured in pageviews or clicks.
• Visual Editor – A WSYWIG editor that loads your website and lets you adjust the visitor experience for your campaign however you like.
• AI copy generator – Accelerate variation ideation and configuration with AI-powered suggestions in the Visual Editor.
• Enable shadow DOM support for the Visual Editor – Use the Visual Editor to make changes to shadow DOM elements.
• Responsive design – See how changes you make with the Visual Editor will look on a responsive site.
• Style elements with CSS in the Optimizely Web Experimentation Editor – Style page elements with CSS in the Visual Editor.
• jQuery for nontechnical users – Use jQuery in the code editor to further personalize your variations.
• Dynamic websites and single-page applications – Enable support for dynamic websites and single-page applications (SPAs) to trigger campaigns based on changes that happen on a page, even when the page does not reload.
• Activate pages in Optimizely Experimentation and Optimizely Personalization – Activate your campaign after certain conditions are met during the page-loading process or the user's journey throughout your site. This is helpful if your site is built on a SPA.
• Load synchronous and asynchronous code changes in Optimizely Web Experimentation – Load resource-intensive components asynchronously so users do not have to wait to interact with your page.
• Shared code: Run custom JavaScript and CSS across all variations – Add your own customized JavaScript or CSS code to your campaigns and apply it to an entire campaign across all variations.
• Custom code in Optimizely Web Experimentation and Optimizely Performance Edge – Use custom JavaScript or CSS code to make changes to your site and extend your testing capabilities beyond Optimizely's standard toolkit.
• Use Extensions – Use extensions to streamline experiment creation and reduce code duplication.
• When to use custom code, shared code, project Javascript, and extensions – Custom code runs at the variation level, shared code runs at the campaign level, Project JavaScript runs at the snippet and can affect all campaigns, and extensions are more reusable across campaigns.
• Controlled traffic allocation ramping – Ramping is when you gradually expose traffic to new test variations. The process can introduce inefficiency and risk if you ramp your traffic carelessly. Controlled ramping of your traffic allocation lets you mitigate risk without compromising data accuracy or time to statistical significance. 
• Schedule experiments and experiences – Schedule campaigns to start and stop at a specific time.
• Optimize based on paid ad campaigns or search engine marketing – Use query strings to personalize your campaigns.
• Stats Accelerator – The Stats Accelerator manipulates traffic to minimize time to statistical significance. It monitors ongoing experiments and uses machine learning to adjust traffic distribution among variations.
• History of how Optimizely Experimentation controls Simpson's Paradox in experiments with Stats Accelerator enabled – Learn about the history of the Stats Accelerator and how it works in Optimizely Personalization.
