Eastside Co has a particularly strong association with Shopify, both through e-commerce development and SEO. The company was one of the earliest UK agencies to build a substantial reputation for Shopify-specific e-commerce services, and it still focuses heavily on these areas.

Because of that, Eastside Co probably makes more sense for established Shopify brands than businesses running several e-commerce platforms at once. Alongside SEO, the company also handles Shopify design, development, and migration projects.

What Makes a Great E-commerce SEO Agency?

Technical SEO Expertise

Technical SEO issues can quickly damage e-commerce SEO, particularly on larger websites with thousands of products and category pages. Indexing issues, crawl waste, redirect chains, duplicate content, and broken canonicals can all have a big impact on how search engines process an online store.

Faceted navigation is another common problem. Filtered URLs can quickly multiply page counts if the site structure is not managed carefully. Pagination can also create issues, particularly on large category pages with extensive product inventories.

Good e-commerce SEO services should have a deep understanding of how platforms like Shopify, Magento, and WooCommerce handle these diverse technical issues. That experience is very important once a business starts expanding product ranges, international pages, or seasonal category structures.

Platform Experience

Shopify, Magento, WooCommerce, and BigCommerce all have different SEO problems. For example, a Shopify store may struggle with duplicate collection pages and rigid URL structures, while a Magento site can get very difficult to crawl if you expand layered navigation too aggressively.

So, it’s important to hire an e-commerce SEO agency with expertise in the particular platforms that you use. For example, a company with strong WooCommerce experience may not automatically understand how large Magento builds behave under heavy product loads or international expansion.

You should also check whether the agency has experience handling platform migrations. E-commerce redesigns and replatforming projects can damage rankings if redirects, category structures, and product URLs aren’t handled properly.

Revenue-Focused SEO

Traffic growth is often a goal for e-commerce SEO, but traffic growth alone is useless if it’s not coupled with the right search intent. Ideally, you want to hire e-commerce SEO services that look beyond vanity metrics and focus on actual, tangible results like revenue growth, conversions, customer retention, and so on. Remember, a retailer selling high-margin products may earn more from a smaller amount of qualified traffic than a store that pulls in far larger but less qualified visitor numbers through broad informational terms.

That is why the best e-commerce SEO agencies in the UK tie SEO more closely to CRO, analytics, and product performance. Category intent, internal search behaviour, product filtering, and checkout friction can all affect commercial performance alongside rankings themselves.

Digital PR & Authority Building

Links still carry a large amount of weight in e-commerce SEO, particularly for competitive product searches and crowded retail sectors. Even smaller e-commerce brands can hold their own against national retailers if they can impress Google with a strong backlink profile indicating a lot of external authority.

This is why many e-commerce SEO agencies also handle digital PR campaigns alongside technical SEO. Product-led campaigns, press coverage, buying guides, and industry commentary can all help e-commerce brands to build much stronger search visibility over time.

AI Search Readiness

Google search results are changing rapidly, and already look extremely different from how they did just a few years ago. AI Overviews, product panels, discussion results, Reddit threads, and heavily expanded SERP features all now compete for attention alongside traditional organic rankings.

That shift has meant that e-commerce SEO strategy now has to change and adapt very quickly. It has also pushed many e-commerce SEO agencies toward structured product content, stronger entity signals, clearer category information, and more detailed on-page copy. Thin product descriptions and weak category pages can tank your e-commerce SEO strategy once search engines start pulling richer answers directly into the results pages, so it’s very important to find e-commerce SEO services that blend AI search readiness with a robust content strategy.

How much does e-commerce SEO cost in the UK?

Pricing for e-commerce SEO services varies widely, depending on factors such as site size, product count, competition level, and the amount of technical work involved. For example, e-commerce SEO for a smaller Shopify store with a few hundred products will usually cost far less than a large Magento site managing thousands of URLs across several countries.

Freelancers and smaller boutique agencies often charge somewhere between £1,000 and £3,000 per month for lower-complexity e-commerce SEO work. Mid-sized e-commerce campaigns may fall within the £3,000 to £10,000 range, particularly when the work involves a reasonable amount of technical SEO, content production, and digital PR.

Large e-commerce brands, on the other hand, can spend beyond £10,000 per month on e-commerce SEO services, especially during migrations, international expansion projects, or major category restructures. Some agencies also charge separately for technical audits, digital PR campaigns, or platform migration work rather than rolling everything into one retainer.

SEO timelines vary, too. Smaller technical fixes can improve visibility relatively quickly, while larger category campaigns and authority-building projects can take much longer to affect rankings and revenue. A good e-commerce SEO agency won’t make any solid promises or guarantees regarding result timelines – instead, they’ll detail the work they plan to do, explain how this will help your e-commerce SEO strategy, and issue regular reports and updates.

Choosing the right e-commerce SEO agency for your business 

Different e-commerce businesses face very different e-commerce challenges. For example, a fashion retailer managing constant stock turnover will need a very different SEO strategy from a company selling specialist industrial products with long buying cycles and smaller search volumes. So you need to think carefully about your specific SEO needs before hiring any e-commerce SEO company.

The platform you use makes a difference, too. Some agencies lean heavily toward Shopify SEO, while others spend far more time on Magento migrations, technical audits, or international e-commerce campaigns. The best e-commerce SEO agencies in the UK will have broad experience of every relevant platform, but it’s definitely worth looking into each potential agency’s track record with your chosen e-commerce platform/platforms.

Frequently asked questions

What is e-commerce SEO?

E-commerce SEO focuses on improving the visibility of online stores within search engines. That includes boosting the profiles of product pages, category pages, filtered collections, buying guides, and other commercial search content tied to e-commerce websites.

Technical SEO usually accounts for a much larger share of e-commerce SEO than standard lead-generation SEO. Product indexing, crawl depth, faceted navigation, canonicals, pagination, and duplicate content can all create problems on larger e-commerce sites, so the best e-commerce SEO agencies in the UK are experts in technical SEO.

How long does e-commerce SEO take?

Some technical improvements can affect search visibility relatively quickly, particularly if indexing or crawl problems already limit rankings. Larger category campaigns and authority-building work usually take much longer.

Competition level can have a relatively big impact on result timelines. A smaller or more niche e-commerce site often gets SEO traction far faster than a retailer competing against national brands and major marketplaces.

Is SEO worth it for e-commerce?

Yes – for many e-commerce companies, SEO can be one of the largest long-term acquisition channels once category pages and product visibility begin ranking consistently.

That being said, paid advertising still plays a major part in e-commerce growth – though rising ad costs have pushed many online retailers toward stronger organic visibility (gained through strong e-commerce SEO).

Which e-commerce platform is best for SEO?

There is no single answer to that question because the right platform for any given e-commerce brand depends heavily on the business’s size and complexity.

Shopify is generally a good choice for smaller and mid-sized e-commerce brands, particularly companies wanting simpler platform management. Magento generally suits larger and more technically complex e-commerce operations. WooCommerce appeals to businesses that already use WordPress and want more flexibility around content management.

What’s the difference between e-commerce SEO and normal SEO?

E-commerce SEO usually involves far larger websites, more technical complexity, and much heavier emphasis on category architecture, product indexing, and internal linking than ‘normal’ SEO.

For example, a local lead-generation website may contain only a few dozen pages, so it doesn’t require a complex technical SEO strategy. Large e-commerce stores, on the other hand, can contain tens of thousands of URLs, requiring sophisticated, multifaceted e-commerce SEO strategies and techniques to optimise.

How do I choose an e-commerce SEO agency?

Start by making a shortlist of the best e-commerce SEO agencies in the UK (this article should help). Then, work out exactly what you need from an e-commerce SEO agency, and compare your needs to what each option on your shortlist offers. Look closely at platform experience, technical SEO capability, reporting quality, and e-commerce case studies.

When you get to the stage of contacting each potential e-commerce SEO agency, ask who handles technical SEO work internally and how reporting ties back to revenue rather than traffic alone.

How much should I pay for e-commerce SEO?

How much you pay for the services of an e-commerce SEO agency will depend a lot on the services you need, the size of your company, the goals you want to achieve, how much competition you’re facing, and so on. As a very broad guide, smaller e-commerce SEO campaigns often start around the £1,000 to £3,000 per month range. Mid-market e-commerce campaigns usually cost more, particularly when technical SEO, content production, and digital PR all feed into the same account.

Large e-commerce brands can spend well beyond £10,000 per month depending on site size, international targeting, and migration work.

Can SEO increase e-commerce sales?

Yes, the best e-commerce SEO in the UK can increase your e-commerce sales through SEO – particularly if category pages target commercially relevant searches and product pages convert visitors effectively once they arrive on the site.

However, it’s important to remember that traffic growth alone does not automatically translate into stronger revenue. Product pricing, conversion rates, site structure, and user experience can all affect commercial performance alongside rankings themselves. So, look for e-commerce SEO experts that prioritise revenue and conversion rate optimisation as well as simply increasing organic traffic.
