Since we have already reviewed classic web harvesting software, we want to sum up some other scraping services and crawlers, scrape plugins and other scrape related tools.
Web scraping is a sphere that can be applied to a vast variety of fields, and in turn it can require other technologies to be involved. SEO needs scrape. Proxying is one of the methods which can help you to stay masked while doing much web data extraction. Crawling is another sub-technology indispensable in scrape for unordered information sources. Data refining follows the scrape, so as to deal with the unavoidable inconsistency of harvested data.
In addition, we will consider fast scrape tools, making our life better, and some services and handy scrapers which enable us to obtain freshly extracted data or images.
As we have been considering web scraping for positive use, there is also the aspect of the negative use of scraping for the purpose of stealing other bloggers’ proprietary content. Let’s consider some anti web scraping WP plugins.
As for a web content ownership the main indicator here is the indexing done mainly by Google. This means that if the content is scraped and immediately reposted, Google might be fooled to index it as the original, while the genuine source will be counted as content farming. Higher ranking sites might have better chances of being indexed earlier than sites with the original content, and the latter might even get a mark for being spam. This is not necessarily a tendency, but in the past some precedents have happened. This seems ridiculous, but through a published feed the offenders might detect and quickly scrape the original content for repost.
