Best Practices for Web Scraping with Octoparse

Respect Website Terms of Service: Before scraping any website, review its terms of service to ensure compliance with scraping policies. Some websites may have specific guidelines regarding data extraction, and violating these terms could result in legal consequences or IP blocking.
Use Proxies Responsibly: When scraping multiple pages or websites, consider utilizing proxies to avoid IP blocking. However, use proxies responsibly and rotate them appropriately to prevent excessive requests from a single IP address.
Optimize Scraping Efficiency: To improve scraping performance, use Octoparse's feature to load only the necessary data and avoid unnecessary page elements. Limiting the amount of data retrieved can significantly reduce scraping time and resource consumption.
Regularly Update Scraping Tasks: Websites frequently change, such as layout updates or URL modifications. Regularly review and update your scraping tasks to ensure continued data extraction accuracy.
Handle Error Cases: Web scraping may encounter errors due to website changes, connectivity issues, or data variations. Configure Octoparse to handle these error cases gracefully, such as by setting up retries or notifications when issues arise.

Web Scraping a Site with Pagination

download Octoparse
When you sign in, the homepage should have a "new task" button like this:
Click on it, and then enter the URL from which you want to scrape data, and click "save." For our example, we will use this website URL.
Now, you are on the website that you want to scrape. At the top of the screen, you should see a "browse" toggle. If you just want to surf the website to determine what information you will scrape or something like that, you can press that toggle.
If any ad modal or something similar pops up during your web scraping task, simply click on the "x" or "close" button to close it, than click on the "click element", inside "Tips" modal.
In our example, we want to scrape the website with pagination, so we need to loop through all pages where the products are listed. Go to the bottom of the page and click on the "next" button. If your website doesn't have a "next" button, click on the number "2" or anything that sends you to the next page with products.
When you click on "next", you will see this "Tips" modal, and you want to click on "Loop click next page".
Next, you want to click on the link that leads you to the particular product, in our example it is "In Her Wake".
A modal will show up, and you should click on "Select All".
Then another modal will appear, and you should click on "Loop click each URL".
Now, on the product page, click on every element that you want to scrape from each product (green items are clicked).
On this "Tips" modal, click "Extract data."
Now you are ready to go, click "run".
Choose your preferred way to scrape. I'll choose "Run on your device" "Standard mode".
Data is being scraped now.
When all products have been scraped, choose your preferred way to export the data. I'll choose Excel.
That's it! You have your data in Excel sheets.
