E-commerce entrepreneurs continuously demand new ways to broaden their customer base.

Establishing trust and expanding their loyal customer base is not just about attracting new customers; it's about taking the time to nurture ones and improve the overall customer experience. 

Here are the five actionable strategies to help e-commerce businesses thrive.

1. Leverage social proof like a pro

Social proof isn’t just a buzzword—it’s your ticket to credibility.

Customers reviews, testimonials, and user-generated content (UGC) are the modern equivalent of a friend’s recommendation, and they work wonders.

A 2023 study showed 85% of consumers are more likely to shop with a brand tied to loyalty programs—often because they encourage actions like leaving reviews.

1.1 Showcase reviews with impact

Don’t let great feedback sit in the shadows.

Feature five-star ratings and customer quotes on product pages, your homepage, and even checkout prompts.

Platforms like Trustpilot or Yotpo can streamline this, pulling in fresh reviews effortlessly.

Glossier nails it by pairing skincare reviews with before-and-after shots, while Allbirds highlights eco-friendly shoe feedback to reinforce its brand ethos.

1.2 Tap into UGC

Get customers to share their experiences—think unboxing videos or Instagram posts—and turn those into marketing assets.

A branded hashtag like #YourBrandCampaigncan spark a wave of content and UGC.

A stellar example of this UGC masterclass is e.l.f. Cosmetics.

The hashtag #elfcosmetics has soared to 2.1 billion views, while searches like “package unboxing of e.l.f.” and “unboxing e.l.f. products makeup” have pulled in 86.5 million and 112.6 million views, respectively.

Known for its irresistibly cute packaging—complete with the catchy “Get ready to get e.l.f.ing amazing” on its boxes—e.l.f. has turned customer excitement into a marketing goldmine.

1.3 Encourage reviews smartly

Not every happy customer will sing your praises unprompted.

Offer a nudge—50 loyalty points, a $5 coupon, or free shipping on their next order—for a detailed review with a photo. It’s a small investment for a big trust boost.

Tip: Hit customers with a post-purchase email 7-10 days after delivery, when they’re ready to rave about your product. Toss in a discount for their next buy to keep the cycle going.

Also, user-generated content (UGC) such as photos or videos that customers have shared, not only brings some elements of the company but also can be the marketing power.


2. Optimise for peak season and sales days with precision

With roughly 260 business days a year (excluding weekends and holidays), the key is knowing when to lean in.

Holiday sales alone pulled in over $221 billion for U.S. e-commerce in 2023, and peak moments like Black Friday or back-to-school season are where the action’s at.

2.1 Prep your inventory

Stockouts kill momentum—17% of cart abandonments happen when items vanish.

Use past sales data or tools like Google Trends to forecast demand.

2.2 Staff up strategically

High-traffic days bring more questions and shipping demands.

Bring in extra customer service reps or warehouse support to keep things seamless. A quick chat response during Cyber Week can turn a browser into a buyer.

2.3 Craft seasonal content

Draw in shoppers with timely seasonal blogs or guides—like “10 Must-Have Gifts for the Holidays.”

It’s a magnet for organic traffic and positions you as the go-to source. Pair it with an email blast for extra reach.

For example, Anthropologie’s 'Best Gifts for Holiday' campaign, which we discussed in our review of successful Christmas campaigns from last year, stands out as a great case study.

Tip: Start Q4 planning in September, using Shopify Analytics or Klaviyo to predict trends. Test your site speed too—laggy pages during peak times can send customers running.


3. Master the art of building a targeted customer base

Your customer base is the foundation of your e-commerce success, and growing it starts with focus.

Blanket marketing wastes time; segmentation—grouping customers by demographics, habits, or purchase history—lets you hit the mark.

HubSpot found 60% of loyal customers spend more when offers feel personal.

3.1 Personalise with purpose

Ditch generic emails for targeted ones.

Tools like Klaviyo or Mailchimp can send abandoned cart reminders with a 10% off nudge tied to the exact item. A pet store might say, “Rover’s treats are waiting!” with a product pic to reel them back.

Bigblue Tip

Post-purchase tracking emails are often underrated, but they’re a golden opportunity. Bigblue turns them into a win with branded, customer-friendly features:
- Order status, items, and support info in one view.
_ Real-time ETA tracking.
- Proactive delay alerts.
- Fully customised branding.

3.2 Stay connected

Keep your audience engaged with bi-weekly newsletters, SMS updates on new drops, or a VIP Facebook group. It’s about building a relationship, not just pushing sales.

3.3 Use data wisely

Dive into Google Analytics or your CRM to spot your top spenders or frequent buyers. Reward them with early sale access or exclusive previews—they’re your growth engine.

Tip: Add a “VIP Signup” pop-up with a 10% first-purchase discount for an email and a quick question like “What’s your favorite category?” It’s a simple way to kickstart a targeted base.

4. Supercharge retention with loyalty programs

Retention is where the real money’s made, and loyalty programs are your ace in the hole.

They keep customers coming back—and spending more. Data shows top loyalty members drive 15-25% more revenue than non-members.

4.1 Create tiers

Set up levels—Bronze, Silver, Gold—where perks like free shipping or exclusive discounts unlock with more purchases.

Sephora’s Beauty Insider program keeps customers hooked by rewarding their loyalty with tangible benefits.

4.2 Spread the word

Don’t let your program fly under the radar. Highlight perks on your homepage, in emails, and at checkout.

A banner like “Join Now, Earn 2x Points This Week!” can spark sign-ups fast.

4.3 Reward more than purchases

Points for buying are solid, but add extras—$10 off for referrals or bonuses for social shares. It’s a low-effort way to boost engagement and reach.

Tip: Launch a “Double Points Weekend” every quarter, paired with a limited-time offer to drive sales. Push it via SMS or notifications for instant impact.

5. Better mobile shopping experience

Mobile isn’t a trend—it’s the backbone of e-commerce today.

Over 50% of global web traffic comes from smartphones, and that’s only growing.

But here’s the catch: 57% of shoppers won’t recommend a brand with a subpar mobile site.

Get this right, and you’re golden. Here’s how:

5.1 Prioritise speed

Slow load times tank conversions—53% of mobile users bounce if a page takes over 3 seconds.

Optimise images, trim heavy code, and use accelerated mobile pages (AMP). Google’s Mobile-Friendly Test can pinpoint fixes fast.

5.2 Streamline payments

Make checkout a breeze with Apple Pay, Google Wallet, or PayPal. One-tap options cut friction and keep shoppers moving.

5.3 Boost app use

If you’ve got an app, offer a 15% off coupon for first downloads.

Then use push notifications for restocks or flash sales—like “Your Favorite Sneakers Are Back, 20% Off Today!”

Tip: Explore AR if it fits—letting customers virtually “try” glasses like Warby Parker’s Try at Home program can elevate the experience and reduce returns. Pair it with top-notch mobile security to build confidence.

Growing your e-commerce customer base isn’t a one-and-done deal—it’s a smart blend of trust, timing, and connection.

Social proof and loyalty programs build relationships, while peak-day planning and mobile finesse bring in the crowds.

Stay sharp, lean on data, and keep your customers at the heart of it all. These hacks aren’t just ideas—they’re your edge in a crowded market.
