Selling online has challenges a regular website doesn't

Hundreds of product pages, filters that generate endless URLs, products that sell out and disappear. Ignoring these quirks is why so many stores with good products never get the traffic or the sales. We account for them from the start.

Why online stores trust 3CWeb

We understand the problems unique to a store

Hundreds of product pages, filters that generate endless URLs, near-identical variants: challenges a services website never faces, and ones we know how to solve.

Design built to sell

Clear product pages, a simple checkout and fast load times, because a beautiful store that doesn't convert isn't worth much.

15+ years of experience

We have helped small and medium stores sell more, combining development, SEO and advertising with a single team.

Results you can measure

We set up analytics from the start so you know which product, channel and campaign is actually bringing in sales.

Want to go deeper into the detail?

We wrote a guide on ecommerce SEO: how it differs from SEO for a regular website, and what to do with duplicate product pages, filters and out-of-stock items.

Frequently asked questions

Which platforms do you work with for ecommerce?

We work with leading ecommerce platforms such as WooCommerce and Shopify, integrating payment gateways, stock and shipping management, all optimised to sell. For the right case, we also build custom solutions.

Can you improve my store's SEO if it's already built?

Yes. We audit product pages, filters and category structure to find what's holding back your organic traffic, and fix it without rebuilding the store from scratch.

Can the store be combined with ad campaigns?

Absolutely. We combine development and SEO with Google Shopping, Google Ads and social media campaigns to drive sales from day one.

What happens with products that go out of stock?

We don't just delete the page: that destroys the rankings it has already built up. The usual approach is to keep it live, clearly marked as out of stock, with alternatives or a restock notice. More detail in our guide to ecommerce SEO.

How much does an online store cost?

There is no single rate: it depends on the number of products, the integrations you need and whether you want a custom build. We start with a free audit and give you a detailed quote.

Will I be able to manage products myself afterwards?

Yes. We deliver self-manageable stores and train you to update products, prices and stock without depending on us for every change.
