# Copywriting services that sell

We write the copy that makes customers understand what you sell and why it's worth it: brand messaging, website copy, product descriptions and ads. We work with companies that have a good product but tell its story badly, with one concrete goal: more inquiries and sales from the same visits.

## Who it's for

It's for companies whose copy describes what they do but doesn't convince anyone to buy.

- Service firms whose website talks about "integrated solutions" and never says what they do or for whom.
- Online stores with product descriptions copied from the supplier or missing entirely.
- Brands entering another market that need Spanish or Portuguese copy that doesn't read like a translation.
- Teams writing ads at the last minute, always with the same message.
- Wholesalers sending confusing terms over WhatsApp and getting the same questions again and again.

## What's included

Copy written for every place your customer decides, built on one core message that stays consistent everywhere.

| Deliverable | What it includes | Timeline |
| --- | --- | --- |
| Messaging architecture | Promise, proof, objections and key messages per audience. | About 1 to 2 weeks |
| Website copy | Homepage, services, about, FAQ and calls to action. | About 1 to 3 weeks |
| --- | --- | --- |
| Product descriptions | Titles and descriptions with benefits, dimensions, use and searched terms. | Based on catalog size |
| Ad copy | Headline and body variants for Meta and Google. | About 3 to 5 days |
| --- | --- | --- |
| WhatsApp messages | Template replies, wholesale terms and inquiry follow-ups. | About 3 to 5 days |
| Language versions | Spanish and Portuguese written natively, not translated word for word. | About 1 to 2 weeks |

Approximate timelines; we confirm them in the proposal.

## How we do it

The messaging architecture takes about 1 to 2 weeks; then we write channel by channel, starting where it moves sales most.

1. **Interviews**: We talk with you and your sales team to hear how they explain the product.

Week 1

2. **Research**: We read reviews, customer questions and competitors.

Week 1

3. **Messaging**: We define the promise and key messages, and you approve them.

Weeks 1 to 2

4. **Writing**: We write each channel's copy in your brand's voice.

Weeks 2 to 4

5. **Test and refine**: We measure which copy converts best and adjust.

From week 4

## What we measure

Good copy shows up in the numbers, not just in how it sounds.

- Conversion rate of rewritten pages.
- Clicks and inquiries for each ad variant.
- Repeat questions that stop arriving on WhatsApp.
- Google rankings for pages and products with new copy.

## Frequently asked questions

**How much does website copywriting cost?**

It depends on the number of pages or products, channels, languages and whether it includes the messaging architecture. We don't charge per word, because short, well-thought-out copy can take more work than long copy. After the free diagnostic we send a fixed proposal with scope and price.

**How long does it take?**

The messaging architecture takes about 1 to 2 weeks, and a company website's copy about 1 to 3 more weeks. Product descriptions depend on catalog size. We give you a staged calendar in the proposal.

**Do you write in my brand's voice?**

Yes. We start from interviews with you and your team and define the voice in writing, with examples of what to do and what to avoid. We write Argentine Spanish with vos, Brazilian Portuguese with você and direct English, always without empty phrases.

**What do I need to give you?**

Time for one or two interviews, access to your website, catalog and social media and, if possible, real customer questions or reviews. The more we know about how your team sells, the better the copy.

**Is there a minimum term?**

A one-off project has no lock-in. If you choose a monthly copy plan for social, ads or a blog, the minimum is 3 months, because that's the time needed to test messages and see what converts. After that we continue month to month.

**Does the copy help SEO?**

Yes. We write for people first, but using the words your customers search Google with, in titles, headings and descriptions. If you also want a content plan to rank, it combines with our SEO service.
