These days, web scraping can either done manually or with the help of web scraping programs.

Web scraping tools fetch and download your pages for viewing, and then extract the highlighted data without compromising on quality.

If you are looking to scrape an entire website, you must adopt some strategies and take care of the content quality.

Manual scraping: Copy-paste method:

The first and most famous method to scrape an entire website is manual scraping. You would have to copy and paste a web content manually and classify it into different categories.

This method is used by non-programmers, webmasters and freelancers to obtain data and steal web content within a few minutes.
