I claim no true expertise on this due to neither being a lawyer or having consulted a lawyer about this specific issue, but there are a number of legal precedents that have been set for and against, but not much in terms of laws explicitly allowing or forbidding it, so currently itвЂ™s considered highly situational. Sometimes there can be undocumented ones that exist just to assist in serving the page, but can be leveraged if youвЂ™re willing to figure out the details. Many sites provide web APIs which provide more efficient, machine friendly formats than a web page, so itвЂ™s usually worth it to search the site to see if there is one. Beyond that, however, scraping should be treated as more of a last resort. Because it is such an essential service for both sites and search engines, quite a bit of technology has built up around accommodating this particular form of scraping, and efforts are made on the part of crawlers to be respectful of the siteвЂ™s bandwidth and wishes over what should and shouldnвЂ™t be crawled. The main exception to this is web crawlers, which are a type of web scraping that search engines use to learn about sites and know when to show a page as part of a search. Modern websites are often built on top of databases and other formalized data storage methods, but they are usually intended as a presentation layer for humans to interact with and not for any sort of automated ingestion by machines. The general goal of web scraping is to extract data from a website without the use of an API or another type of strict data format. There are certain limitations, of course, but with some creative problem solving, you can do quite a bit with this ETL tool. ItвЂ™s tricky but the short answer is yes, sorta.
