Be careful with that approach.
Copying a site “exactly as it is” (especially products/content) can cause legal issues and also SEO problems (duplicate content won’t rank).
What you’re looking for is called
web scraping—basically extracting data from a site automatically using tools or scripts
There are tutorials/videos for this, but they usually involve:
- Inspecting the site structure (HTML)
- Extracting product data (title, price, etc.)
- Handling pagination (since you have thousands of products)
You can search for:
- “Scrapy tutorial” (Python)
- “BeautifulSoup web scraping tutorial”
- “How to scrape eCommerce products”
There are also tools (no-code) like web scraper extensions, but for 18k+ products, coding is usually more reliable.
One more thing: instead of copying 1:1, it’s better to extract data and
rewrite/structure it differently to avoid issues later.
