How to Capture Lazy-Loaded Product Reviews on an Ecommerce Page

By Freedom251 Team · · 4 min read

To capture reviews that appear only after scrolling or clicking “Load more,” open Chrome DevTools before reloading the product page, record the Network panel, then trigger the review widget and inspect the requests that appear. Check each response rather than guessing a hidden API: the trigger, request and response format depend on the retailer and review widget.

Capture the review requests in Chrome DevTools

  1. Open the product page and DevTools. In Chrome, open DevTools before reloading the page. Select the Network panel, then reload. The panel records activity while it is open; opening it after the page has loaded can leave earlier requests out of the log. See Chrome’s Network features reference and Inspect network activity.
  2. Prepare the request log. Clear existing entries if they make the sequence hard to follow. Turn on Preserve log if navigation or a reload might clear useful entries. If you need to observe first-visit behavior, consider enabling Disable cache while DevTools is open. These controls affect what you observe; they do not make a site return reviews that it otherwise withholds.
  3. Find the review widget and trigger another batch. Scroll the review list, click its load-more control, or use its pagination controls. Reviews can be presented using pagination, load-more buttons or infinite scrolling; Google Search Central specifically includes product-page reviews among content that may load incrementally. See Google’s guidance on pagination and incremental page loading.
  4. Compare the log before and after the action. Look for requests that appeared when you interacted with the widget. Filter for likely XHR or fetch traffic if useful, then inspect a candidate request’s Initiator, Preview or Response, along with its headers and timing. Chrome’s tutorial shows how a page interaction can trigger a request and how to inspect its details.
  5. Verify the result. Confirm that the response contains review text or review data, and that the same interaction added the corresponding reviews to the page. If another batch requires another click or scroll, repeat the interaction and compare the next request. Do not assume a particular endpoint, parameter name or response structure until you have observed it on this page.

Tell what kind of review loading the page uses

Use the page’s visible behavior and the request log together. None of these patterns guarantees a particular URL or data format.

What you do What to check
Click “Load more” Does the new batch append to the current list or replace it? Does the action create a distinct page URL, or only a background request?
Choose a review page number or next-page control Does the browser navigate to a different URL? Does the request return readable review text or structured data? Does moving to the next page consistently retrieve another batch?
Scroll through an infinite list At what point does a request appear? Does the visible URL change as a new chunk becomes primary, or does loading happen in the background?

These checks help identify how this particular widget behaves; they are not universal properties of ecommerce sites. A response may contain review data, but it may also contain something else, so inspect it and compare it with the visible page.

What DevTools can and cannot capture

The Network panel is useful for observing requests made by a live browser. It does not establish that every review is available in one response, or that a retailer provides a stable public endpoint. The reliable evidence is the request generated by the interaction and the response returned in that session.

For programmatic DevTools extensions, Chrome documents chrome.devtools.network.getHAR() and request-finished events in its chrome.devtools.network API reference. HAR access does not include request content by default; use the request content method when you need response bodies. The API documentation also cautions that requests made before DevTools was opened may be missing, so reload with DevTools open.

Why reviews may be visible to you but not a crawler

A person can scroll or click a control in a live browser. Google says its crawler generally discovers URLs from links and generally does not click buttons or trigger JavaScript functions that require user action. As a result, reviews revealed after interaction may not appear in the initial markup or be discoverable to a crawler. That crawler behavior does not prevent you from observing browser requests in DevTools.

If you own the site, Google recommends loading relevant lazy content when it enters the viewport. For infinite scroll, its guidance recommends persistent unique URLs for chunks, stable content for a given URL, sequential links and updating the visible URL when a new chunk becomes primary. Use Search Console’s URL Inspection Tool to check the rendered HTML. See Google’s lazy-loading guidance.

Or skip the browser setup

If you want a screenshot of the page rather than to inspect its underlying review data, ScreenshotNeo is a screenshot API and MCP server for developers. A single request can capture a page as an image or PDF; it does not replace DevTools when you need to inspect request bodies. Its cleanup options remove cookie and consent banners, newsletter popups and chat widgets before capture, and each can be turned off. Bot checks, blank pages, timeouts and failed loads are not billed; cache hits are not billed either, with the response identifying the page verdict and billing status in headers. AI agents can use its MCP server tools, including take_screenshot, get_page_info and capture_pdf.

Example cURL request:

curl -G "https://api.screenshotneo.com/v1/shot" -d access_key=YOUR_API_KEY --data-urlencode url=https://stripe.com -o shot.webp

For setup, parameters and response details, see the ScreenshotNeo documentation. The free plan includes 1,000 screenshots per month with no card; paid plans start at $5 for 3,000. Sign up for free and get 1,000 screenshots a month with no card.
