A favorite button, or heart button, is the small heart icon that lets a shopper save a product with one tap. It is the front door to a wishlist. One tap stores the item for later, instead of forcing a buy-or-leave choice. For online stores, this tiny button captures interest that would otherwise slip away.
The button gives shoppers a simple way to say “I like this item.” One tap adds the product to their wishlist. No forms, no menus, no friction.
On WooCommerce or Shopify, the icon sits on product cards and product pages. A filled heart usually means saved, while an outline means not yet. It is the same mental model people know from social media.
Behind the icon sits the full product wishlist. The button is just the visible doorway to it. Get the doorway right, and shoppers actually use the room behind it.
A good favorite button tells you what just happened. The most common pattern is an outline heart for unsaved and a filled heart for saved. Some stores swap the color too, often to red or a brand accent.
Small touches help confirm the action. A quick scale-up animation or a tiny toast that says “Saved” reassures the shopper. Without that feedback, people tap again and again, unsure if it worked.
The icon should also stay visible after the save. Hiding the heart once it is filled hides the only way to undo the save. A persistent toggle keeps shoppers in control.
Most shoppers are not ready to buy on the first look. Around 70.22% of carts get abandoned by people who simply were not ready. A heart button gives that hesitation a place to land.
The tiny action also creates attachment. Once a shopper saves an item, it starts to feel like theirs. The endowment effect shows owners value an item about twice as much as non-owners.
Save counts can add social proof on top. A high count signals that a product is loved by others. The pull is similar to reviews, which make a product 270% more likely to sell.
Placement and clarity decide how often it gets used. The button should be easy to spot and obvious in meaning. A confusing or hidden heart simply gets ignored.
Most shoppers now browse on a phone, so the heart has to be finger-friendly. WCAG 2.1 sets a minimum target size of 44 by 44 CSS pixels. Below that, fat-finger taps get harder.
Nielsen Norman Group goes further. Their guidance is a touch target of at least 1cm by 1cm in physical size on the screen. That accounts for real finger pads, which run 1.6cm to 2cm wide.
Spacing matters as much as size. The heart should not sit right next to Add to Cart or a quick view icon. A few millimeters of breathing room stops accidental taps and the frustration that follows.
Accessibility goes beyond size. Add an aria-label like “Save to favorites” so screen readers can announce it. Make sure the focus state is visible for keyboard users too.
Imagine a WooCommerce store called Lumen Lighting that sells lamps. At first, the only action on each product is Add to Cart. Many shoppers who are not ready simply leave.
The store adds a clear heart button to every product card. Now shoppers have a softer option than buying now. They can save a lamp and keep browsing.
A shopper named Eve saves three lamps for a future room makeover. Without the heart, she would have left with nothing saved. Now her interest is captured and waiting.
Popular lamps start showing high save counts. New visitors see those numbers and feel more confident. The counts quietly nudge them toward a purchase.
Eve returns a week later and buys two of her saved lamps. The heart button turned a near-miss into a sale. A single icon reshaped how shoppers move through the store.
Add to Cart is a commitment to buy soon. It suits shoppers who have already decided. For everyone else, it can feel like too big a step.
The favorite button is a lighter, lower-pressure action. It lets undecided shoppers save without committing. That keeps them engaged instead of bouncing away.
The two work best side by side. Add to Cart serves ready buyers, while the heart serves the much larger group still deciding. Together, they turn one harsh choice into a friendly path.
People often use the two names for the same thing, but they can mean slightly different things. A favorite button is usually a quick, one-tap save. A wishlist button often opens a menu so the shopper can pick which list to save to.
The heart is best when speed matters most. It works well for fashion, decor, or anything browsable. A wishlist menu shines when shoppers keep several lists, like a wedding registry or a gift list.
Many stores use both, with rules. A single tap on the heart drops the item into a default list. A long press or a secondary icon opens the menu for shoppers who want more control.
Looking at large marketplaces is a fast way to learn good patterns. Etsy, Amazon, and Pinterest all use a version of the favorite button. Each one tunes it to their audience.
Etsy puts a heart on every product card and pairs it with a save count. The number is shown when it is large enough to impress. Shoppers can also pick a named collection for each save.
Amazon mostly uses a Save for Later link inside the cart and a heart on some product cards. The brand leans into the cart as the main holding area. The heart is a quiet secondary tool.
Pinterest is built almost entirely around save behavior. Every image has a clear Save button instead of a heart, in a strong brand color. The lesson is that the label and color matter as much as the icon shape.
You do not need to copy any one brand. Pick the parts that fit your store. A clear icon, a clear state change, and an optional save count are the patterns worth keeping.
Small changes to the heart can swing how often it gets used. The first thing to test is placement. Try the top-right of the product image versus near the title or price.
Icon style is the next lever. Compare a thin outline heart with a bolder filled one. Add a label like Save if your audience is older or less familiar with icons.
Color and contrast finish the trio. The heart should stand out from the product image, but not so much that it feels like a sale tag. A soft gray on rest and a brand color when saved usually wins.
Save counts only help when they are strong. A simple rule is to hide the number until it crosses a threshold. Many stores hide the count under 10 or 25 saves.
Track how the count affects clicks and conversion, not just saves. A jump in saves with no lift in sales can mean the count is creating cold interest. Tune the threshold until both numbers move.
For low-traffic stores, a count-free heart is often safer. Show counts only on bestsellers or seasonal pages where the numbers tell a strong story.
Put it where shoppers already look. The most common spots are product cards and the main product page. Near the image or the title works well. The key is that it is easy to see and tap.
No, but a heart is the most understood symbol. A star or a Save label can work just as well. What matters most is that the meaning is instantly clear. Avoid icons shoppers have to stop and decode.
It can help when the numbers are strong. A high save count acts as social proof and builds confidence. For products with few saves, it is better to hide the count. Show the signal only when it works in your favor.
Yes, in most cases. Forcing a signup before the first save kills the action. A better path is to store guest saves in a cookie or local storage. Offer an account later, when the shopper wants to sync across devices.
The favorite or heart button looks tiny, but it changes how shoppers behave. It gives undecided visitors a low-pressure way to save, captures fleeting intent, and can show social proof. Make the button clear and easy to reach, and that one small icon becomes a steady source of saved sales.
