Ensure that you have the right platform and a functional theme

Consider a platform such as BigCommerce, Magento, Shopify, or others that can handle the volume you anticipate for your business when developing an eCommerce website. Building a multi-channel empire requires a robust platform, particularly if you plan to sell different currencies to multinational customers. After you choose a platform, the next critical step is selecting a theme. It should:

1. Is visually appealing
2. Customizable to your brand
3. Loads quickly
4. Responsive
5. Works on all browsers

Customers interact with this part of your site, so it must look good and function well.

The SEO Process and Site Performance

Use SEO techniques so that your pages receive a higher ranking and shoppers find you. PageRank is still a vital factor for traffic. The CTR drags out more than half from the first position to the second in the search results.

Site performance and page load speed also affect user experience and Google's ranking. Impatient shoppers abandon slow sites quickly. According to one statistic, 40% of shoppers leave the site if it takes longer than three seconds to load.

Take advantage of mobile customers with a responsive website

Having every website optimized for mobile seems like a no-brainer, but thousands of merchants still use outdated themes and websites that only display correctly on desktops.
According to Statista, 49.7% of page views in 2017 came from mobile devices. Therefore, you are missing out on nearly 50% of your potential customers if you are not mobile responsive.
Users should be able to search, scroll, browse, and purchase right from their phones and other devices.

Trust and data security depend on the security

It takes time for a customer and merchant to build trust, which is crucial for sales. Using HTTPS protocol for every page will build trust, not just the payment information pages. Customers expect that their personal information is secure.
Payment information and transactions require a high level of security. If you integrate with credit cards, your site must be compliant with PCI (Payment Card Industry).
If your system is hacked, you become liable. Keep vital data such as credit card numbers off your company's website.

5.Offer a limited product selection and search the site

Buyers have decision paralysis when integrating with too many options, and they will walk away rather than make a decision. Here are some ways to overcome this problem:

1. By limiting your products to your niche, you can better serve your customers.
2. Pre-select the best products. Despite the possibility of twenty products available, limit their choices to two or three top products.
3. Reduce the clicks in your checkout process. Each additional click reduces the likelihood of a completed sale.

Make sure your site search is fast, reliable, and scalable. 30% of visitors use site search. It's a vital feature for any eCommerce site. Don't rely on the default search engine on most pages. Instead, invest in a robust, third-party search engine and provide shoppers with as many filters as possible to help them narrow their search.

6.Put quality pictures and videos on your product page

Whether you like it or not, consumers will give you no more than 10 seconds of their attention. So it would help if you go straight to the point, grabbed their attention, and kept them on the page until you could explain in greater depth.
An excellent way to grab attention is with photos, and the video keeps it with videos. The key to success is to have one or both above the fold on every page.
Video tells a story like no other mode. So try and add as many product videos as possible. One retailer (Stacks and Stacks) reports conversion rates of 144% higher from shoppers who watched a video than those who didn't.

7. Make the transaction as painless as possible

You've done everything right now. The customer found what might be looking for with the site search, the product descriptions, and the photos.
Now that the product is in her shopping cart and her credit card is in hand, the checkout process throws up more hurdles.

1. Unexpected shipping charges
2. No return policy available
3. Certain payments not accepting transactions

What can you do to prevent her from abandoning the cart? You just took all the excitement out of her shopping spree. How can you prevent this?
First, address the shipping objection. Then, post your shipping policies and fees on both your home page and product page. However, this will eliminate any unpleasant surprises.
Upgrade your platform if it restricts payment types. For example, you should be able to accept international credit and debit cards, online payment gateways like PayPal and Stripe, as well as digital wallets like Apple Pay and Amazon Pay.
