I have been using Reoon YellowPages Scraper for several months now and I have to say that I am extremely impressed. This software has exceeded all of my expectations and has proven to be an invaluable tool for my business.

A few importan points about this tool:

1. Searching using state names (i.e. NY; CA; FL etc) gives better quality results than the city level search. However, if to get maximum data, city level search is required (but this can take long time). And make sure to separate the location and keywords with a semicolon (Not comma. I was making that mistake innitially).

2. Scraping speed is fairly fast. However, to get the best speed, keep the website crawling disabled if you do not need that. You can crawl the websites separately if you need that.

3. I recommend scraping a small batch of cities each time instead of going for all 36000 cities. This reduce system resourse requirements and works better in most cases.

4. There can be duplicates if you go for city level search and start scraping neibour cities. However, this looks like a problem of yellowpages itself. But a build in duplicate removal feature would be great. Not a big issue for me.

5. The quality of the scraped emails are fairly high than any other lead scraping tools I have tested. I am getting a lot higher open rate with this one. However, you should always clean the email list with an email verification service first to avoid bounces.

7. If you are going to scrape a large number of data, using Proxy or VPN is highly recommended. Keep in mind that, you will need to get that on your own, like all other web scraper.

8. One thing I must mention is that their support is really premium. Although the setup is fairly simple and most probably you will not need to contact the support, but its always great to have.

Overall, I highly recommend Reoon YellowPages Scraper to anyone who is looking to grow their business. It has been a great investment for me and I am sure it will be for you too.
