Wishlist is a key feature in e-commerce websites. These websites benefit from increased conversion rates, optimized revenues, and simplified consumer buying processes.
According to studies, the majority of website visitors don’t typically buy anything on their first visit. They frequently become perplexed by several products. A nice (and pertinent) solution for them is a wishlist. Users are able to add their favorite products to a list. For a store with a lot of options, this will make it simpler for users to make the decision. They can also quickly locate their preferred products when making subsequent purchases.
Users can also utilize wishlists to recommend their favorite goods to family members and friends. This is beneficial for your website. This will encourage more orders from customers who share the same interests on your website. Or assume that you will receive more orders that are gifts from your customers to one another on special occasions (such as birthdays, Christmas, etc.).
For sellers, understanding client preferences and issues also makes it simpler for store owners to cater to customers, which helps to boost online revenue for sellers.
Based on the fundamental API of WooCommerce, this plugin was created, ensuring compatibility, performance, and security. Because the plugin has been tested with the most widely used themes and is guaranteed not to interfere with the user experience, we also recognize the value of integrating with themes.

The wishlist is one of the most powerful and popular tools in an ecommerce shop. Thanks to the wishlist, users can:
<ul>
<li>Save their favourite products, find them quickly and easily at a later time and buy them.</li>
<li>Share the wishlist with relatives and friends for Christmas, birthdays and similar occasions so they can buy them one of the products from the list.</li>
<li>Share the wishlist on social networks and get indirect advertising for your store.</li>
</ul>
This means that you’ll be able to loyalise customers, push them to buy and attract new customers any time a wishlist is shared. Not bad for one plugin only, don’t you think?
Our YITH WooCommerce Wishlist has more than 900,000 active installations and that’s why it’s the most popular wishlist plugin ever.
To celebrate this record and say thanks to all the plugin users, we’ve decided to release a new 3.0 version that has improved the design tremendously and added many new options.
If you like the new design, please, leave a review to help the plugin grow!
