Mercury Copywriting is a Lyon-based writing studio that delivers words with the speed of the messenger god and the precision of a Swiss watch. We write websites, funnels, emails, and brand messaging for businesses that cannot afford to be ignored — or to wait.
Six specialist writing services — each with a clear deliverable, transparent investment, and a turnaround that respects your deadlines without sacrificing quality.
End-to-end website copy from hero to footer — structured around your visitor's decision journey, optimised for search, and written in a voice your customers recognise instantly as yours.
High-conversion landing pages and multi-stage funnels — awareness to purchase — with every touchpoint calibrated to move the prospect forward.
Welcome flows, nurture sequences, launch campaigns, and newsletters that earn opens, keep subscribers reading, and convert attention into revenue.
Four phases. No wasted motion. Every step delivers a tangible output you approve before we advance.
We disappear into your brand: customer interviews, competitor audits, review mining, voice analysis. When we emerge, we understand your audience's language as well as they do. Deliverable: a strategic brief you approve.
Before writing starts, we map the information architecture: page hierarchy, argument sequence, CTA logic, keyword targeting. You approve the skeleton before we add muscle and skin.
Senior copywriters craft every sentence with intent. Headlines are tested for stopping power, body copy for persuasion, CTAs for action clarity. We write tight — every word justifies its existence.
Your copy arrives in structured, implementation-ready format with SEO notes, A/B variants, and designer annotations. Revisions based on your feedback. Final delivery with full documentation.
"Mercury rewrote our SaaS website in seven days. Trial signups increased 61% the following month. Same product, same traffic — just sharper words."
"The launch funnel they wrote converted at 4.8%. Our previous agency managed 1.7% with identical traffic. The copy was the only variable. That number speaks for itself."
"Their email sequences generated €210k in attributed revenue within five months. Open rates above 40%. The writing is precise, personal, and relentlessly effective."
Every day of weak copy is a day of lost conversions. Let Mercury write words that move at the speed of your ambition.
