Recognize this situation?

  • Your store gets visits, but few people buy, and you cannot tell whether the problem is the price or the product page.

  • Products were listed with the supplier’s description, the same one dozens of competitors use.

  • Sizes, materials and details are missing, and customers keep asking the same questions before they buy.

  • The brand barely shows up outside the store, and people who do not search for your name never find out it exists.

Who it is for and who it is not

E-commerce content writing is the work of presenting every product in your store well: a title customers search for, a clear description, complete sizes and details, photos in the right order and copy that persuades. Hire it when your store gets visits but sells little, or when listings were copied from the supplier.

A good fit for

  • Online stores with visits and few sales, or with products listed in a hurry.
  • Amazon, Etsy and eBay sellers who want more complete listings and fewer questions.
  • Brands that want to be known outside their own store, with regular content.
  • Stores selling in the US and Brazil that need copy in both languages.

Not a fit for

  • Anyone looking for paid ad management or boosting: we do not work with paid media.
  • Anyone who needs product photography: we advise on order and what to show, but we do not shoot.
  • Anyone expecting guaranteed sales: content helps sell, but price, stock and delivery also count.

Frequently asked questions about E-commerce content

How much does it cost to improve my product listings?

Fixing a product already listed costs $19 and a new, complete description $39, in batches from 20 products. A review of the whole catalog, up to 500 products, is $1,490, and the monthly store plan is $1,290.

Why does a good description help sell more?

Because customers cannot hold the product: the page has to answer what they would ask a salesperson. A title with the right words makes the product show up in search; complete sizes and details remove the doubt that stops the purchase and prevent returns.

What is e-commerce SEO?

SEO is the work of making your page show up on Google when someone searches for what you sell. In a store, that means using the words customers type in titles and descriptions, organizing categories and giving each product its own copy, not the supplier’s.

Do you also fix listings on Amazon and other marketplaces?

Yes: we fix the title, spec sheet, description and photo order following each marketplace’s rules, such as Amazon, Etsy and eBay. Complete listings get fewer questions and rank better in the marketplace’s own search.

Can AI make up information about my products?

We do not let it: AI writes only from the data you give us, such as the supplier spreadsheet, spec sheet and photos, and a person checks price, sizes and claims before publishing. When something is missing, it becomes a question for you, never a guess.

Do you publish directly to my store?

Yes, with the access you grant: through the platform’s import spreadsheet or the store dashboard, on Shopify, WooCommerce, BigCommerce or Magento. For large catalogs, automated import belongs to our AI for e-commerce service.

How does content help my brand become known?

Through consistency: posts and emails about products, uses and news, published every week, put the brand in front of people who do not search for it by name yet. The same automated routine we use on our profiles publishes at the agreed time, after you approve.
