FAQs
What is eCommerce SEO?
eCommerce SEO is the process of optimising online stores to rank higher in search engines, increase traffic, and drive more sales.
How is eCommerce SEO different from general SEO?
It focuses specifically on product and category pages, site structure, and conversion-driven elements rather than just content or blogs.
How much does eCommerce SEO cost?
Costs vary depending on the size of your site and the agency. UK agencies typically charge between £1,000 and £5,000 per month.
Which platform is best for SEO – Shopify, Magento, or WooCommerce?
All can rank well, but the best platform depends on your business model, scale, and technical resources.
