I do Agree with Gravy.
But consider this (IMHO) before u start to learn :
The Good – There’s not much that’s good about web scraping. Unless you’re looking to use unsavory tactics, steal competitors’ content and pricing, or use other sites’ intellectual property, web scraping is just all around bad.
The Bad – The really bad news about web scraping is that it can lead to the theft of your content, which, if used on other sites, can significantly affect your SEO performance and rankings. It can also give competitors access to your proprietary pricing and product information, which ultimately gives them a leg up in the marketplace with the customers you’re actively seeking.
The Ugly – In a nutshell, web scraping can be a huge detriment to your brand. It can threaten your sales and conversions, lower your site’s SEO rankings or even get you blacklisted, negate the benefits of the content you’ve worked hard to produce, and can cause you to spend even more resources to make up for its damaging effects.
