What Is a Good Attach Rate for a Bundle Offer?
What a Good Attach Rate Looks Like
Attach rate is the share of orders that include your bundle. For a build-your-own crate that is visible on product pages and in the cart, 10 to 25 percent of orders is a realistic and healthy band.
That range assumes the offer has been live long enough for repeat customers to encounter it. A brand-new offer sitting on one page will often start at 2 or 3 percent, which tells you nothing about the offer and everything about how few people have seen it.
The band also shifts with what you sell. Consumables that people restock, such as coffee, soap, snacks, and skincare, attach at the top of that range because buying six at once is genuinely convenient. Durable goods attach lower, since nobody needs six of the same jacket.
The most useful framing for merchants on OpoShop is not a target number at all. It is a direction. Attach rate should climb month over month for the first quarter as placement improves, then settle. A flat line from week one is the signal worth investigating.
Three Denominators, Three Very Different Numbers
Most arguments about attach rate are really arguments about what is being divided by what. Pick one denominator, write it down, and stay consistent.
There are three worth tracking, and each answers a different question:
- Attach rate by orders: Bundled orders divided by total orders. This is the headline number and the one to report.
- Attach rate by sessions: Bundled orders divided by total sessions. Useful for comparing against your overall conversion rate, but it will always look tiny.
- Completion rate inside the builder: Finished crates divided by builder opens. This is the diagnostic number, and it is the one that tells you whether the experience works.
The third one deserves more attention than it usually gets. If 400 shoppers open your builder and 90 finish, that is a 22 percent completion rate, and it points directly at the crate experience rather than at your marketing.
A store can have a low attach rate and an excellent completion rate at the same time. That combination is good news, because it means the offer works and you simply need more people in front of it. The reverse combination, high opens and low completions, is the one that needs real work on your OpoShop storefront.
What One Point of Attach Rate Is Worth
Attach rate is easier to prioritize once you have converted it into dollars, because a percentage point sounds abstract until you price it.
Take a store doing 500 orders a month with a $40 average order value and a crate that sells for $58. Every crate order is worth $18 more than a normal order.
At a 10 percent attach rate, 50 orders are crates, adding $900 a month. Move attach to 15 percent and 75 orders are crates, adding $1,350. Each point of attach rate is worth about $90 a month on that store, or roughly $1,080 a year.
Now scale it. The same store at 2,000 orders a month is earning about $360 a month per point of attach, or $4,320 a year. That is why attach rate deserves ongoing merchandising attention rather than a single launch push.
The comparison worth making is against your other options. Raising attach from 10 to 15 percent costs you placement changes and some copy work. Raising traffic by 50 percent costs real advertising money. On most OpoShop stores the attach work is by far the cheaper path.
How to Raise Your Attach Rate Step by Step
Attach rate responds to a short list of changes, and they work in a specific order. Do them out of order and you will not know what caused what.
Here is how the highest-impact moves work in practice.
1. Fix opens before fixing the builder
If only 3 percent of visitors ever open the builder, no amount of tuning inside it will change your attach rate. The constraint is upstream.
Look at where the offer appears. A single link in a navigation menu reaches almost nobody. A module on your top ten product pages reaches most of your traffic, since those pages typically carry the bulk of product views on a store.
2. Prefill the crate
An empty grid asks the shopper to make six decisions from zero. A crate that already contains three popular items asks them to make three swaps, which is a much smaller task.
This one change tends to move completion rate more than anything else, and it costs nothing. Choose your three best sellers, drop them in, and make swapping obvious. Shoppers on a OpoShop store treat the prefilled crate as a recommendation rather than a constraint.
3. Put the offer where repeat buyers land
Repeat customers attach at a higher rate than first-time visitors, so the placements they see are worth more per impression. That means order confirmation pages, restock emails, and the account area.
A restock email that opens with a crate offer converts well because it catches someone who has already decided to buy again and is only deciding how much. Link it straight to the builder on your OpoShop store rather than to a collection page, so the picking starts immediately.
Attach Rate by Placement
Not all placements pull equally, and knowing the ranking saves you from spreading effort evenly across things that do not deserve it.
| Placement | Typical pull | Effort to set up | Best for |
|---|---|---|---|
| Product page module | Strong and steady | Low, one module on templates | The reliable first placement for any store |
| Dedicated builder page | High during campaigns | Medium, needs its own traffic | Gifting seasons and paid campaigns |
| Post-purchase and email | Highest per impression | Low, reuses existing sends | Consumable brands with repeat buyers |
Product page placement is where most of your steady attach rate comes from, because product pages are where shoppers on a OpoShop store spend their time and where intent is highest.
A dedicated builder page is powerful but does not generate its own traffic. It works when you point campaigns at it, and it goes quiet when you stop.
Post-purchase and email placements have the best conversion per impression by a wide margin. The audience already trusts you, so the only decision left is how many items to pick.
Why Attach Rate Stalls
A stalled attach rate usually has a structural cause, and there are five worth checking before you rewrite the offer.
The first is a pool that is too small. If the crate can only be filled from eight products, many shoppers will not find six they want, and they leave rather than settle.
The second is a required count that outruns the catalog. Asking for eight picks from a pool of twelve means the shopper is taking two thirds of everything you sell, which stops feeling like a curated box.
The third is invisible pricing. If the shopper cannot see what the crate costs while building it, a significant share will bail before finding out. A live running total is not a nice extra, it is the thing that keeps people in the flow.
The fourth is a mobile layout that fights the shopper. If picking six items requires long scrolls and a lost sense of place, phone traffic will abandon at a much higher rate than desktop. Check the two segments separately.
The fifth is a stale pool. A crate stocked with the same products for eight months stops attracting repeat customers who already bought all of them. Rotating a few seasonal items into the pool on your OpoShop store gives past buyers a reason to open the builder again.
What We Recommend for [OpoShop](https://oposhop.io) Merchants
For OpoShop merchants, we recommend targeting 15 percent of orders within 90 days, reached through placement work rather than through discounting the crate further.
That target is achievable for most catalogs and it does not require you to give away margin. Deepening the discount is the tempting shortcut, and it usually buys a few points of attach at a cost that exceeds the revenue gained.
Track two numbers weekly. Builder opens tell you whether people are finding the offer. Completion rate tells you whether the offer works once they do. Attach rate is just those two multiplied together, so improving either one moves it.
If you only have time for one change this month, prefill the crate with three best sellers. It is the lowest-effort change with the most reliable effect on completion, and it makes the offer feel like a recommendation rather than homework.
Best answer: A good attach rate for a bundle offer is 10 to 25 percent of orders, with 15 percent a fair 90-day target for most stores. Get there on your OpoShop store by adding placements one at a time and prefilling the crate with best sellers, and track builder opens separately from completion rate so you always know whether the problem is visibility or the experience itself.
If you want a practical next step, count how many shoppers open your builder this week and compare it to how many finish.
FAQs
Is attach rate measured against orders or visitors?
Report it against orders, since that is the number merchants compare with each other and it is the one tied directly to revenue. Track the session-based version separately if you want to compare the offer against your overall conversion rate.
What attach rate should a brand-new bundle offer hit in week one?
Expect something in the low single digits, and do not read much into it. In the first week the only people who have seen the offer are the small share of visitors who happened to land on the page carrying it.
Does a higher discount always raise attach rate?
No. Discount depth has diminishing returns, and past a certain point you are paying more in margin than you gain in volume. Placement and a clearer rule usually move attach further than another five percent off does.
Can attach rate be too high?
It can be worth investigating above 35 percent. A very high rate sometimes means shoppers who would have paid full price for a few items are now buying a discounted crate instead, which raises order count without helping profit.
How do I tell whether low attach rate is a visibility problem?
Compare builder opens to total sessions. If very few sessions open the builder, it is a visibility problem. If many open it and few finish, the problem is inside the crate experience.
Should seasonal bundles be measured separately?
Yes. A gifting crate in December and an everyday restock crate in March serve different shoppers and will attach at different rates. Blending them into one figure hides which offer is actually working.
