Whether you promote programs or provide information to students, Youtube is the best way to communicate to a wide audience. It is the second-largest search engine in the world, next to Google. As Google and other search engines tend to favour videos, you can improve your search engine ranking by sharing videos on Youtube with good titles, tags, and descriptions. You can also convey your brand messages on Youtube with the help of videos, as they are a perfect method to capture the emotion and the physical attributes of what you are promoting.

Youtube scraping allows you to scrape video data, subscriptions, comments, ranking, recommendations, and ads. With the help of the Youtube scraper, you can scrape your searches by picking data from the selected Youtube URL page. You can now scrape the channels, videos, and their details and the comments and subtitles, which opens a whole new dimension to analyze video data. You can scrape both auto-generated and added captions in various languages using web scraping.

Why Do You Need To Scrape YouTube Data?

Scraping data from Youtube is useful because of some of the following reasons.

  • It is easy to calculate the frequency of brand mentions, audience reach, and their reactions with the help of the right data. For instance, businesses can use this useful data to calculate the Return on Investment (ROI) for advertisements or referrals from Youtube channels. This way, they can scale their marketing campaigns accordingly. 
  • With the help of Youtube scraping, you can pick out, analyze, and delay the spread of fake news and harmful or illegal content.
  • You can collect data for any research, follow emerging topics and trends, and even predict new ones by country, language, or globally.
  • To make better choices, you can find the reviews of services and products that you consider buying.
  • The Youtube comments section comprises user sentiment data that reveals different reactions to the videos’ content. It is very useful in understanding how your viewers are engaging with the content. But before using a Youtube scraper, you need to remember that the trolls are a common part of the comments section. Therefore, you can not consider the negative comments as legitimate feedback.

Scraping Youtube Comments Using Python

You need to follow the below steps for scraping comments from Youtube using Python.

Install Packages

You have to import the necessary packages using the Python command as shown below.

!pip install datakund-bot-studio
!pip install youtube-comment-scraper-python

Import Packages

Now, you need to import the required packages.

from youtube_comment_scraper_python import *
import pandas as pd

Comments Section

You need to open your desired Youtube video link and go to the comments section using the below commands.

youtube.open("https://www.youtube.com/watch?v=rSDy5AdfRDI")
youtube.keypress("pagedown")

You will get the following output by executing this command.

Scraping Comments

After executing the above piece of code, you need to open your web browser where your video is already opened. It will automatically perform Page Down and scrape comments, so you need to wait for the process to finish. The time taken by this step can vary depending on the number of comments on a video.

data = []
currentpagesource=youtube.get_page_source()
lastpagesource=''

while(True):
    if(lastpagesource==currentpagesource):
        break
        
    lastpagesource=currentpagesource
    response=youtube.video_comments()

    for c in response['body']:
        data.append(c)
        
    youtube.scroll()
    currentpagesource=youtube.get_page_source()

Constructing Dataframe

Now, we remove the duplicate data and convert our list to a dataframe. Then, we export our data to a CSV file.

df = pd.DataFrame(data)

df = df.replace('\n',' ', regex=True)

df = df[['Comment', 'Likes']].drop_duplicates(keep="first") 

df.to_csv('data.csv',index=False) 

We check our data by using df.head() as shown below.

df.head()

Using a Proxy

Youtube proxy is an intermediary server that provides data exchange between the device and the servers. It helps to create an indirect connection allowing you to bypass the firewall of your system administrator or Internet service provider. With the help of proxies, you can increase views on your Youtube videos and get more comments.

You need to open your command prompt and type the following.

$ git clone https://github.com/MShawon/YouTube-Viewer.git

$ cd YouTube-Viewer

$ pip install -r requirements.txt

Further, check your Google Chrome version and download the same version chromedriver.exe from https://chromedriver.chromium.org/downloads and place it in the chromedriver_win32 folder.

You need to filter the below command to filter good proxies if you’ve got a large proxy collection. Afterward, you have to use GoodProxy.txt for a proxy python file.

$ python proxy_check.py

Why Do You Need To Use Proxies?

The several possible reasons to use a Youtube proxy are as:

  • Usually, at the management’s request, Youtube is often banned in educational institutions and office networks. So, you need a Youtube proxy to avoid bans and keep your access stable.
  • Some countries prohibit access to Youtube at the state level because its content does not comply with their national policies. It means no citizen can use Youtube within the country. So, you have to find a Youtube proxy provider with global IP addresses to unblock Youtube videos.

Conclusion

Youtube is a great place for building an individual platform, and it is a place where you can do a ton of customer and digital marketing research. The comments section of Youtube videos gives a lot of insights about the expectations of people and what they like/dislike. You can scrape Youtube comments using Python, and you should use proxies when scraping them. It is because proxies protect you from getting blocked, and they also allow you to do more targeted research. You can use dedicated proxies for scraping Youtube. Though they are expensive, they are more secure than the other proxies.
