"Go To Web Page" - open the targeted web page
Create a pagination loop - scrape all the reviews from multiple pages
Create a "Loop Item"- scrape all the reviews on one page
Extract data - select the data and remove the unwanted information
Run extraction - run your task and get data

1)"Go To Web Page" - open the targeted web page

Click "+ Task" to start a new task with Advanced Mode
Paste the URL into the "Website" box
Click "Save URL" to move on

Tips!

If you are landing on Amazon for the first time, you may encounter a robot detect which needs you to enter security code. In this case, you can switch to browser mode by clicking on top right of the build-in browser. And then type in the code to pass the detection. Finally, click to switch back to select mode.

2) Create a pagination loop - scrape all the reviews from multiple pages

If you are using the latest version of Octoparse, the "Workflow Mode" would be automatically on. If not, you could turn on the "Workflow Mode" by switching the "Workflow" button in the top-right corner in Octoparse

Scroll down the page and click “see all reviews”

To scrape all the reviews, we need to add this step to lay out all the reviews on this page.

Scroll down the page and click the “Next page” button
Click "Loop click the selected link" on the "Action Tips" panel

3）Create a "Loop Item"- scrape all the reviews on one page

The Reviews are organized on the page as a list. We need to build a "Loop Item" to loop extracting each review one by one.

Select the first title in the built-in browser
Click "Select all"
Click "Extract data from the selected elements"

Tips!

To learn the detailed information about capturing a list of items, here is the tutorial you might need.

After looping through the reviews, we found that there are totally 11 items instead of 10 in the looping list. The last one is not the item we need. That's because the XPath is not accurate enough. So we have to modify the XPath in "Loop item".

Click "Loop item"
Add "[position()<11]" at the end of original XPath

So the final XPath should be "//body/div[1]/div[2]/div[1]/div[2]/div[1]/div[1]/div[4]/div[3]/div[position()<11]". It means to select first 10 items in the page since there are only 10 items in the page.

Tips!

Modifying XPath in Octoparse is important when you need to locate items accurately.

Rename the fields by selecting from the predefined list or inputting on your own
Click "OK" to save the result.

5) Run extraction - run your task and get data
