If we talk about cases when there is nothing at all for the site, then there is a need for content, a prototype, design, programming, then the deadlines are as follows:
- Landing: 2−3 weeks
- Corporate website: 4−6 weeks
- E-commerce: from 1.5 months
The first week of any online product is always spent on studying competitors, collecting references and information for filling your site with content. Deadlines are evaluated at the stage of conclusion of the contract, and are always respected during its execution
