How to Increase Online Sales: An Ecommerce Playbook (2026)

Online revenue only has three inputs: how many people arrive, what share of them buy, and how much they spend when they do. Every tactic you have ever been sold moves one of those three. Most stores chase the first one, because buying traffic feels like action, when the cheapest money is usually sitting in the second and third.

So this guide works in that order. Do the arithmetic, find where you are actually losing people, then fix that specific thing. A list of twenty tactics applied in random order is how stores stay flat while staying busy.

Start with the arithmetic

Revenue is sessions times conversion rate times average order value. Write down your three numbers before you do anything else.

A store with 20,000 monthly sessions, a 1.8% conversion rate and an S$85 average order value makes about S$30,600 a month.

Now compare the cost of moving each input by a third:

Identical outcome, very different bills. The traffic route costs you again next month. The other two are mostly fixed work on assets you already own.

This is why the order matters. If your conversion rate is 1.8% and the comparable benchmark is around 2.5%, buying more traffic means paying to send more people through a leaking funnel.

Benchmarks worth measuring against

Use these to locate your problem rather than to feel good or bad.

Two readings of that table.

If your mobile conversion rate is less than half your desktop rate, you have a mobile problem, not a product problem, and that is where your next month goes.

And the Singapore market growing at 17.7% means flat revenue is actually declining share. Worth saying plainly to anyone who thinks holding steady is holding steady.

Find the leak before you fix anything

Pull a funnel report for last month. Shopify, WooCommerce and GA4 all give you this.

Whichever stage shows the steepest drop is the only one worth working on this month. Fix it, measure for four weeks, then look again.

The sections below are ordered by stage, so skip to yours.

Leak at the product page

If people arrive and never add to cart, the page has not answered their questions.

Show the full cost early. The most common reason for abandonment at the cart stage is a shipping cost that appears only at the end. If you can, state delivery cost and timeframe on the product page itself. If you offer free delivery above a threshold, say the threshold on the product page, not in the footer.

Answer the objection the product actually has. For apparel, that is sizing and returns. For electronics, compatibility and warranty. For food, shelf life and storage. Put it in the page, not a separate FAQ page. If your customer service inbox answers the same question weekly, that question belongs on the product page.

Use real photography. Supplier stock images on a Singapore store read as a dropshipper, and shoppers here are quick to spot it. Multiple angles, scale reference, and one image showing the product in use.

Reviews with substance beat a star rating. A 4.8 average with three one-line reviews does less than a 4.4 average with twenty detailed ones. Ask for reviews a sensible interval after delivery, which depends on the product, not seven days for everything.

Make the page load. A product page that takes five seconds on mobile loses people before the content matters. See Core Web Vitals explained and website speed optimisation for the technical side.

If product pages are also your main organic entry point, the product page SEO checklist covers the overlap between ranking and converting.

Leak between cart and checkout

This is usually one of three things, and shipping is the first.

Shipping cost shock. Test a free-delivery threshold set slightly above your current average order value. It addresses abandonment and average order value at once, which is why it is usually the highest-return single change available to a small store.

Too many steps. Ask for the minimum. Every optional field costs you orders. Guest checkout should exist, and it should not be hidden below account creation.

Payment methods people here expect. PayNow is the obvious one for Singapore, and its absence is noticeable. Add the wallets your customers actually use rather than every option available.

Then recover what still leaks. An abandoned cart email sequence is the highest-return automation in ecommerce because the intent is already proven. Three messages works: a reminder within hours, a nudge the next day, and a final one with help rather than a discount. Discounting every abandoned cart trains people to abandon carts.

Our guide on how to reduce cart abandonment goes into the sequence in detail.

Leak inside checkout

If people start checkout and do not finish, the problem is mechanical. Go through it yourself on a phone, on mobile data, as a new customer, and buy something.

Things that routinely break and go unnoticed: the keyboard covering the submit button, postal code validation rejecting valid Singapore codes, error messages that clear the form, a promo code field that implies a code exists and sends people off to hunt for one.

On that last point, a visible promo code field actively costs orders when most customers do not have a code. Collapse it behind a small link.

Also check what your payment provider does on failure. A declined card that dumps the user back to an empty cart loses a confirmed buyer.

Raise average order value instead of buying traffic

Once the funnel holds, this is the cheapest revenue available.

Bundle things that genuinely go together. A bundle that saves the customer a decision works. An arbitrary bundle for a 5% discount does not.

Recommend at the right moment. Related products on the product page compete with the thing they came for. On the cart page, they add to a decision already made. Move them.

Set the free-delivery threshold deliberately. Slightly above average order value, and show progress toward it in the cart. Most platforms do this with an app or a snippet.

Offer a bigger size or quantity. For consumables this is the simplest lift there is, and it costs nothing to add.

Then, and only then, buy more traffic

With a funnel that converts, paid traffic stops being a bet.

The order that works for most Singapore stores: fix what you already have, then expand the channel already producing, then test a new one. Our guide to performance marketing tactics for ecommerce growth covers channel selection, and ecommerce SEO covers the traffic that does not stop when the budget does.

Social discovery is worth its own note. For visual and impulse categories, Instagram and TikTok work as discovery rather than direct response, and the mistake is judging them on last-click return. See growing your ecommerce business on Instagram.

Keep the customers you already converted

Acquiring a customer costs several times more than selling to one again, which makes retention the highest-margin revenue in the business and the most commonly skipped.

A post-purchase sequence that confirms, ships, delivers and then checks in beats a discount code. Build a reorder prompt timed to the actual consumption cycle of your product. And look at who bought twice, because that cohort tells you which products earn repeat business and therefore which ones deserve your ad budget.

Three things specific to selling online in Singapore

GST on low-value imported goods, and who it actually applies to. Since 1 January 2023, Singapore’s Overseas Vendor Registration regime requires overseas sellers and electronic marketplace operators to register for GST and charge it at checkout on low-value goods sold to consumers here. Low-value goods are non-dutiable items located outside Singapore, delivered by air or post, valued at or below the S$400 GST import relief threshold. The rate was 8% from 1 January 2023 and has been 9% since 1 January 2024.

The distinction that matters: this regime targets sellers shipping into Singapore, not a locally registered store selling to local customers. If you are a Singapore entity fulfilling locally, your GST position follows the ordinary registration rules on your turnover. If you drop-ship from overseas, read IRAS’s low-value goods guidance properly, because the obligation may sit with you rather than with the customer at the border.

Either way, display tax-inclusive pricing. A total that changes at checkout is the abandonment trigger covered above.

Delivery expectations are compressed. Singapore is small and shoppers here are used to next-day. A five-day timeframe needs a reason stated on the page, not buried in a policy.

PayNow is expected. Its absence reads as an incomplete store rather than a neutral choice.

Common mistakes

• Buying traffic to fix a conversion problem. It multiplies the leak.
• Changing five things at once. You learn nothing about which one worked.
• Judging a change in a week. Give it four, or seasonality decides your result for you.
• Discounting as the default answer. It trains customers to wait and takes margin permanently.
• Testing on desktop only, when around 65% of retail transactions are mobile.
• Measuring sessions instead of revenue per session. The second one tells you something.

Frequently asked questions

How do I increase online sales without spending more on ads?

Work on conversion rate and average order value rather than traffic. Both are one-off work on pages you already own, and the arithmetic shows a one-third improvement in either produces roughly the same revenue as a one-third increase in traffic, without a recurring bill. Start by finding which funnel stage leaks most.

What is a good ecommerce conversion rate?

Around 2.5% globally and 2.9% in APAC, according to Contentsquare. Treat it as a locator rather than a target, since it varies widely by category and price point. A more useful internal comparison is your mobile rate against your desktop rate.

Why do people abandon their carts?

Unexpected costs appearing late in checkout is the most common reason, usually shipping. Average abandonment is 70.19%, rising to about 85.65% on mobile, according to Baymard Institute. The fix is showing total cost early rather than recovering the abandonment afterwards.

How quickly should I expect results?

Checkout and cart fixes show up within weeks, because the traffic is already arriving. Average order value changes show within a month. SEO and retention work compound over quarters. Measure any single change for four weeks before judging it.

Should I discount to increase sales?

Sparingly. Discounts work as a time-boxed event with a reason attached. Used as a default, they take margin permanently and train customers to wait for the next sale. A free-delivery threshold usually beats a percentage discount because it raises average order value instead of lowering it.

What is the first thing to fix on an underperforming store?

Complete a purchase on your own store, on a phone, on mobile data, as a new customer. Most stores find at least one genuine blocker this way, and it costs nothing. Then pull a funnel report and work on the steepest drop.

Do I need a new website to increase online sales?

Usually not. If the funnel report shows the drop is at the product page or in checkout, those are page-level fixes. A rebuild is warranted when the platform itself blocks the fixes, for example if you cannot add PayNow or edit the checkout. See ecommerce website development in Singapore if that is your situation.

How do I increase average order value?

Set a free-delivery threshold slightly above your current average and show progress toward it in the cart, bundle products that remove a decision rather than just discount, move recommendations from the product page to the cart page, and offer a larger size for consumables.

Where to start this week

Buy something from your own store on your phone. Then pull a funnel report and find the steepest drop. Those two actions take an afternoon and will tell you more than any list of tactics.

If the drop is at the product page or in checkout, that is conversion work: see how to increase your website conversion rate and our CRO checklist. If the experience itself is the problem, start with the ecommerce UX guide for Singapore stores.
