45 USD Website for the Dog and Cat Hotel "PES"
HTML & CSS
Case: Website for the Animal Hotel "DOG", Kyiv
What has been done: a fully functional multi-page website for a private hotel for dogs and cats in Kyiv.
Creation Process
1. Business and Goals Analysis
… Before starting - diving into the essence: who is the client, what is the audience, what objections need to be addressed. For the animal hotel, the main fear of owners is "will my pet be okay?" The entire website is built around answering this question.
2. Structure and Architecture
The website is designed as a single logical path from introduction to booking: Hero → Formats → Prices → Gallery → Conditions → Reviews → Blog → Contacts. Each section addresses a specific barrier before ordering.
3. Copywriting and Content
All texts are written in the "client's language" - without dry templates. Headlines, subheadings, service descriptions, conditions - everything is created from scratch considering the emotional trigger of trust.
4. Layout and UI
Responsive HTML/CSS website with a clean modern design. Implemented: sticky navigation, lightbox gallery with 28 photos, modal review window, Google Maps, booking form with pet and format selection.
5. Blog / SEO Articles
A separate section with 6 thematic articles (preparation for the hotel, nutrition, walking, socialization, etc.) - to attract organic traffic through search.
6. Deployment
The website is deployed on the free hosting Tiiny.host for demonstration to the client. For live use, a custom domain and hosting are connected.
What the client received
A fully ready "turnkey" website with texts, structure, and design
Mobile adaptation for all devices
Booking form, gallery, reviews, map, blog
Connected links to all social networks (Telegram, Instagram, Facebook, YouTube, TikTok)
SEO articles for promotion in Google.
