Picture this: you cut that mobile load time by just 0.1 seconds, as per Google's 2024 speed study, and you will have 8.4% conversions up your sleeve. Plus, add a streamlined checkout and according to the Baymard Institute, expect at least 35% more completed orders for the sake of that profit.

Small Tweaks - Big Gains For eCommerce Platforms
In stark contrast to large-scale endeavours, such as redesigning the checkout page and launching a loyalty program, the micro-conversions are often where the real magic and missed opportunities lie.
a) Buttons Hover Effects
Hover states (any type of animation or color change) enhance the user's perception of the interaction and reward them with visual feedback. Makes CTAs feel interactive, clickable, and alive. Make primary buttons stand out with contrast and micro-animations.
- Micro delays or soft shadows can increase engagement rates on product cards and "Add to Cart" buttons.
---------------------------------------------------------------------------------------------------------------------------------
b) Sticky “Add to Cart” Bars
Whenever a customer scrolls through a product description, a sticky call to action will keep the "Add to Cart" button in view. This reduces friction and keeps intent high, especially on mobile devices.
- Studies performed by Hotjar confirm that stores that implemented sticky cart bars improved mobile conversions by 12%.
---------------------------------------------------------------------------------------------------------------------------------
c) Trust Badges Near CTAs
Considering badges like "Secure Checkout," "Money-Back Guarantee," or "Free Returns," to increase authenticity next to your CTAs. Custom builds allow you to test placement and style without restrictions.
- Use trust signals-such as "Secure Payment via Klarna" or "PayPal" to
---------------------------------------------------------------------------------------------------------------------------------
d) Social Proof & Key Actions
Live counters, reviews, “X people are viewing this site now,” or even mini user testimonials placed near product details can nudge hesitant buyers as micro-psychological cues reinforce trust and urgency.
- By adding social media proof to product pages - close to CTA buttons - has shown a 17% uplift in conversion in A/B tests run by CRO agencies.
---------------------------------------------------------------------------------------------------------------------------------
e) Analytics & Heatmaps
Ensure you track your website by implementing analytics tools. It provides invaluable insights into how visitors interact with your site, what content they engage with most and where they drop off.
- Button click-through rate
- Page & section scroll
- Time on key product sections
- Drop-off points during checkout
- Use tools like Hotjar or Smartlook
Pitfalls Of DIY e-Commerce Platforms
Even the most promising eCommerce ideas can stumble at the start. Whether you're launching your first online store or scaling a brand, avoiding these rookie mistakes is critical to growth and long-term success.
a) Website Builders - Templates
Though it saves time and money, pre-built templates are often not very flexible in terms of scalability. An overwhelming majority of storekeepers have faced issues with customization of templates as they grew their inventory or as they required specific integrations.
TIP: Start with templates only if you have a low budget or if you have a few products. Custom-built stores are for the long term and include flexible UI components and backend systems for future adaptations in scaling.
---------------------------------------------------------------------------------------------------------------------------------
b) Poor User Experience on Mobile Devices
Over 75% of any e-commerce website traffic is from mobile devices, which is a clear sign that desktop-first design is a lost opportunity.
SOLUTION: Build a mobile-first design and use thumb-friendly CTAs, collapsible menus, one-click payment options (Apple Pay, Google Pay), optimize pages and assets for speed and performance. Do extensive testing on various screens and on the devices.
---------------------------------------------------------------------------------------------------------------------------------
c) Over-Optimised System
Overselling your site with too many features, tools, pop-ups or animations can be too much for both users and sellers. Firstly, it slows the load time and performance and secondly, it overwhelms and frustrates users if they don't work, leading to a poor user experience.
RECOMMENDATION: If you decide to use additional plugins/tools, ensure they address a specific user pain point. Use data heatmaps, user feedback or analytics to justify their usage.
---------------------------------------------------------------------------------------------------------------------------------
d) Lack of Trust Elements
No matter how good your product or service is, if users don’t trust your brand, they won’t convert. Don't launch without clear return policies, support or contact, as the following features are crucial trust signals.
Essential Trust Builders:
- Verified customer reviews
- Money-back guarantee
- Clear delivery & return policies
- Contact details and business registration
- Social proof (testimonials, brand partnerships, influencer collabs)
FACT: 92% of people read online reviews before making a purchase. Consider a review strategy, even if that means offering some free stuff for feedback early.

eCommerce Solution: Build Website vs Buy Template
When launching or redesigning an e-commerce website, one of the first (and most important) decisions is whether to build a fully custom website or buy a pre-designed template. Both options have their benefits and disadvantages, however they both serve a very different business goal.
A) Buying a Website Template:
- Fast, Affordable, Restrictive
A template is a predesigned theme or layout available on platforms like Shopify, WordPress, BigCommerce and Wix. These templates are often used by startups, individuals or brands testing the waters.
Template Pros:
- Quick Launch: Within days, you can be online, not weeks or months
- Lower Upfront Cost: Templates start anywhere from £0 – £250, with an array of design options
- Beginner-Friendly: Drag-and-drop editors and WYSIWYG tools mean no coding necessary
- Vesatile Marketplace Options: Platforms like ThemeForest or Shopify offer thousands of designs to choose from
Template Cons:
- Limited Customisation: You’re restricted by the template’s layout and structure
- Template Syndrome: Your site looks like hundreds of others, which makes standing out or feeling premium hard
- Performance: Most templates come loaded with excess code or unnecessary animations and assets
- Scalability: As you grow, custom features may not be supported
When Should You Choose a Template?
- You have no design and development experience
- You’re launching a side hustle or you need a quick store on a budget
- Your product range is limited and doesn’t require complex filtering or custom options
- You want to validate a niche or market segment before investing heavily in tech
- You don’t have access to development resources and you will be managing it yourself
TIP: Choose a lightweight template, designed for mobile-first and has good support from the theme developer. Avoid "do-everything" or "General" themes and select one for your category or niche.
---------------------------------------------------------------------------------------------------------------------------------
B) Building a Custom Website:
- Strategic, Scalable, Future-Proof
A custom-built site is designed from the ground up around your brand, your customer experience and your business goals. It will be developed using headless architecture and modern front-end frameworks, even a modular backend system tailored around workflows.
Custom Site Pros:
- Tailored User Experience: Every page, section and feature is personalized to your brand to direct your customers toward conversion
- Unlimited Flexibility: Multi-location shipping, real-time stock syncing or loyalty program tied to purchase history are all possible
- Performance: Lightning-fast load times, Core Web Vitals compliance and better SEO from day one
- Built to Scale: Your store grows with you, whether you’re expanding product lines, going international, or integrating new tech
Custom Site Cons:
- Higher Upfront Investment: Expect to invest more - time, budget, planning
- Development Time: It can take several weeks to several months
- Ongoing Maintenance: You’ll need ongoing development support
When Should You Use Custom Builds?
- You are an established brand and you want to scale and have full control of your site
- You are seeking a competitive advantage over the competition
- You need unique functionalities - subscription flows, multi-tiered pricing, product personalisation, etc
- You're planning to scale quickly and want to avoid the limitations of a theme-based development process
- You want to optimise every part of the user journey - page speed, accessibility, SEO, micro-conversions, etc
TIP: Think long-term ROI if you're building an ecommerce website. While custom sites require more upfront cost, they often pay for themselves in better conversion rates, lower abandonment and improved brand trust.
