Scrape Related Searches from DuckDuckGo using Python

Contents: intro, imports, what will be scraped, process, code, links, outro.

Intro

This blog post is a continuation of the DuckDuckGo web scraping series. Here you'll see how to scrape Related Search Results using Python with selenium library. An alternative API solution will be shown.

This blog post assumes that you know the basics of selenium

Imports 

from selenium import webdriver

What will be scraped

Process

For some reason request-html can't locate elements at the bottom of the page when using xpath or css selectors, and scrolldown= parameter didn't help either.

This time selenium was used since it is the easiest way to get the data but at the same time, not the fastest.

Selecting CSS selector to grab query and a link and running the script.

Note №1: running selenium in headless mode didn't return any results, or I was doing something wrong.

Note №2: the data could be extracted from the tag without selenium use, but it will be a much more time-consuming process.

Code 

from selenium import webdriver

driver = webdriver.Chrome(executable_path='/path/to/chromedriver.exe')
driver.get('https://duckduckgo.com/?q=fus ro dah&kl=us-en&ia=web')

for result in driver.find_elements_by_css_selector('.result__a.related-searches__link'):
    query = result.text
    link = result.get_attribute('href')
    print(f'{query}\n{link}\n')
driver.quit()

Using DuckDuckGo Related Searches API

SerpApi is a paid API with a free plan.

The difference in using an API solution is that you'll get a faster response since there's no need to render the page. Additionally, iterating over structured JSON is a bit faster process rather than searching selectors from scratch or finding ways to avoid something.

import json
from serpapi import GoogleSearch

params = {
  "api_key": "YOUR_API_KEY",
  "engine": "duckduckgo",
  "q": "fus ro dah",
  "kl": "us-en"
}

search = GoogleSearch(params)
results = search.get_dict()

for result in results['related_searches']:
    print(json.dumps(result, indent=2))
