Yelp search
Yelp is a business directory available in many countries. LetsExtract has a built-in Yelp parser:
Enter keywords and a region. You can enter a city if necessary.
LetsExtract will send your keywords to Yelp, collect search results, go to sites from the list of results, and extract contacts (see also: Crawl depth settings).
Note: Yelp has recently taken measures against parsing, and it returns blank pages, a 403 or 503 error if their sites are accessed by too many users at the same time or too often. We recommend using a proxy when searching in Yelp.
