Optimizely X Web Recommendations is a recommendation engine that makes it easy to introduce visitors to products and content, based on browsing behavior. Recommendations are easy to set up and hands-off once they're published.

With Recommendations, you can test out different algorithms and measure the impact in real time with Stats Engine.

Recommendations also works hand-in-hand with other Optimizely X Web products for more powerful experimentation and targeting.

Read on to learn more about Recommendations. Or, dive in and build your first Recommendations experiment.

1. Set up Recommendations

To implement Optimizely X Web Recommendations, contact your Customer Success Manager.

Optimizely will help you complete the initial setup, so you can start creating recommendations for your site.

2. Build a Recommendations experiment

Once you've implemented Recommendations, it's easy to build and publish recommendations. You'll choose an algorithm, header text, layout, and location for your recommendations and select key metrics to measure success.

By default, Optimizely shows your recommendations to a subset of your visitors. Another subset of randomly bucketed visitors will see the original variation. Stats Engine tracks how each variation performs, so you can measure success in real time and iterate on your Recommendations experiment.

Jump in and build a standalone Recommendations experiment.

Ideas for recommendations

There are many ways to use recommendations on your site. Below, we suggest a few retail and B2B use cases. 

Retail sites:

  • In the checkout funnel, show accessories that complement the items a visitor is purchasing

  • On product detail pages, show alternative items that are related to the product a visitor is browsing

  • Highlight crowd favorites on the homepage

B2B or lead generation sites:

  • Show visitors whitepapers, infographics, blog posts, and other content based on their browsing behaviors

  • Suggest knowledge base articles or community posts to reduce support call volume

Recommendation algorithms

Optimizely offers four algorithms for recommendations.

  • Co-browse: "Website visitors who viewed this product also viewed these other products."
    Consider this algorithm for high-price catalogs, where a visitor is unlikely to purchase more than one item at a time.

  • Co-buy: "Website visitors who bought this product also bought these other products."
    This algorithm is great for low-price checkout funnels, where visitors are likely to purchase complementary products or add several items to an order.

  • Popular Items: "Items that website visitors most frequently viewed or bought."
    This algorithm helps showcase crowd favorites on the homepage. Use it to introduce best-selling items to new visitors.

  • Recently Viewed: "Items that you previously browsed."
    This option helps you remind visitors of items they've already shown interest in.

How recommendations work

Optimizely currently offers four algorithms for showing recommendations to visitors.

Recommendations are generated every 24 hours. So, the catalog information may be up to 24 hours stale, with a mean of 12 hours.
