Many people have erroneous perceptions of web scraping. It is because some people do not respect the excellent work that has been done on the internet and take advantage of it by stealing the content. Web scraping isn’t illegal in and of itself; the issue arises when users utilize it without the site owner’s consent and in violation of the Terms of Service (Terms of Service).

2. The terms “web scraping” and “web crawling” are interchangeable

Web scraping is the process of extracting specific data from a selected webpage, such as sales leads, real estate listings, and product prices. Search engines, on the other hand, trawl the web. It crawls and indexes the entire website, including internal links. “Crawler” is a program that navigates across web pages without a defined purpose in mind.

3. Any website may be scraped

People frequently request web scraping services for email addresses, Facebook postings, and LinkedIn information. Before doing web scraping, it is crucial to consider the following principles, according to an article titled “Is web crawling legal?”

Octoparse introduced a one-of-a-kind tool called web scraping templates, which are preformatted scrapers that cover more than 14 categories on more than 30 websites, including Facebook, Twitter, Amazon, eBay, Instagram, and others.

Perhaps you’ve come across websites that change their layouts or structure from time to time. Don’t get frustrated if your scraper fails to read a website for the second time. There are numerous explanations for this. It isn’t always triggered by being identified as a suspicious bot. Different geo-locations or machine access could potentially be at blame. It’s usual for a web scraper to fail to parse the website in these circumstances before we make the modification.

7. You can scrape at a fast speed

You may have noticed scraper advertisements boasting about how fast their crawlers are. It appears to be promising, as they claim to be able to collect data in seconds.

APIs function as a channel through which you may submit data requests to a web server and obtain the information you need. The data will be returned in JSON format using the HTTP protocol. Facebook API, Twitter API, and Instagram API are just a few examples. However, this does not imply that you will receive any data you request. Because it allows you to interact with web pages, web scraping can help you visualize the process.

9. The scraped data only works for our business after being cleaned and analyzed

Many data integration solutions can assist with data visualization and analysis. Data scraping, on the other hand, does not appear to have a direct impact on business decision-making.
