What Are Yellow Pages?

Yellow pages are the print directory of telephone numbers and ads for companies and organizations in an industry. The information contained in yellow pages is according to the type of business and services the companies offer.

Yellow pages publishers attempted to make online copies of their directories when the internet started to take over the market. The online versions that were made available were referred to as internet yellow pages (IYP).

Compared to the printed versions, internet yellow pages can be updated in real-time so every information present there is current.

The Kind of Information You Can Get from Yellow Pages

For your business to grow and for you to achieve your sales goals, you will need leads. Yellow pages will provide you with information like business name, contact number, email address, state, postal code, website, and it’s sometimes accompanied by a business description.

All of this information is necessary and would be required if you need to contact a potential client to make sales.

You will find a yellow pages website for every country and if you are interested in a company that is located in that country, you can find the information you need on its yellow pages.

What Is a Yellow Pages Scraper?

To begin with, a web scraper itself is a tool that is used to gather data from different websites. It is used to identify the HTML data as it is available on the website, and then convert it to a readable format for further analysis.

This analysis is what would provide results that serve as pointers to guide the business in making informed decisions. Data extraction can be done manually but it is a stressful and time-consuming process.

There is also the possibility of making numerous mistakes and so an automated process is used that would not only provide accurate data but also do it fast despite the volume of data that is required.

Yellow pages scraper is therefore a tool that is built specifically to scrape yellow pages. This tool is meant to search for and extract specific data from yellow pages such as name, contact information, and location amongst others.

Building A Yellow Pages Scraper

When a web scraper is used to extract data from a target website, it contains a workflow that is made up of some elements. They include:

  1. Developing data extraction scripts. This is the first step in building a web scraper and it needs good knowledge in programming and familiarity with a specific coding language. The most popularly used among software developers for data extraction is Python language.
  2. You will also need an additional tool; a headless browser as they give you automated control over web pages. With headless browsers, you can have access to a web page and extract the content to another program, click on links, and do so much more. Nothing appears for users, so they won’t be any trigger for internet activity.
  3. After the required data has been extracted, data parsing makes it readable and suitable for use. Data on the web isn’t easy to understand but once it is parsed, it makes sense and allows for further analysis.
  4. In the web scraping building process to scrape yellow pages, data storage comes in last. Here you can store the extracted and processed data for use and reference purposes.

Web Scraping Path

Data scraping path is part of the preparations you have to do before you begin scraping. You will need to have your list of URLs to the target sites you want to scrape from and this is the scraping path. The scraping path is your library of URLs where the information you need is stored.

Proxies for Web Scraping Yellow Pages

Proxies are necessary when web scraping is involved as they help prevent IP blocks from the target website’s server. If you require a lot of information from a site, you would send multiple requests and if done from a single IP, it would be detected as bot activity and blocked as humans don’t send so many requests at that rate.

Your real IP can also be detected as that of a rival and you will be fed false data which would ruin the whole idea of web scraping. So you can’t separate proxies from web scraping.

There are two main types of proxies you can use for your web scraping tasks and both can be used to keep you highly anonymous. There are residential proxies and datacenter proxies.

You can get different IP addresses from different locations around the world so you can collect data for various markets without being present there. A difference however exists between them both.

Residential IPs are real addresses related to a physical location, and they are issued by the internet service provider. With residential proxies, you will have a low back rate and can extract as much data as you need with low chances of getting caught. They are however very expensive.

Datacenter proxies are from cloud service providers and are not associated with any internet service provider. So the major difference between both proxies is their origin.

Residential proxies are less likely to get blocked among the two as they are tied to a physical location and won’t be detected as from a bot. They also leave no footprints and trigger no anti-bot features in websites unlike with datacenter proxies.

However, not all datacenter proxies get blocked as some are made to get through a website’s security and scrape without being detected. So it also depends on your proxy service provider.
