    Use a Web Scraping API

    If you are comfortable writing your web scraping code yourself, you still need to run it locally. This is fine for small operations, but as your data collection scales up, it will use up precious bandwidth, potentially slowing down your network.

    Using a web scraping API can offload some of the work to a remote server, which you can access via code. This method has several options, including fully-featured and professionally priced options like Dexi, and simply stripped back services like ScraperAPI.

    Use IFTTT To Scrape a Website

    IFTTT is a powerful automation tool. You can use it to automate almost anything, including data collection and web scraping.

    One of the huge benefits of IFTTT is its integration with many web services. A basic example using Twitter could look something like this:

    • Sign in to IFTTT and select Create
    • Select Twitter on the service menu
    • Select New Search From Tweet
    • Enter a search term or hashtag, and click Create Trigger
    • Choose Google Sheets as your action service
    • Select Add Row to Spreadsheet and follow the steps
    • Click Create Action
