Tessera Partners
Content architecture for an executive search website that has to earn international trust.
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 |

What it costs
We don't publish fixed prices. Cost depends on the number of pages or products, channels, languages and whether the full messaging architecture is included. You can order a one-off project or a monthly copy plan. After the free diagnostic we send a fixed proposal.
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.
Shall we talk about your sales?
Tell us what you sell and to whom. We reply on WhatsApp within one business day.
