Check a sample of changed offers on their source pages.
How do you compare product prices across countries?
Open the same product variant in each market you want to check. Save its identifier, seller, currency, stock status and delivery destination beside the price. A store can use a saved postcode or account preference to select an offer, so set those fields deliberately. For example, keep the same size and colour when comparing a pair of shoes, and record whether the displayed amount includes shipping.
Use a stable product identifier to join results across visits. A changed URL or promotional label should not create a second item in your report. If a price changes sharply, inspect the page and check for a different seller, a member-only offer or an unavailable variant. Keep the time of each check so the team can distinguish a current offer from an older snapshot. Schedule checks at a frequency allowed by the site and useful for your buying or pricing work. With rotating requests, each product can be checked separately; with a basket or account-specific offer, keep the same sticky session through the related pages. Before expanding the product list, compare several saved rows against what the website actually shows.
Compare the same product variant and include shipping and delivery settings with the displayed price.
How do you select a country, state or city?
Standard residential proxies support country, state and city targeting through the endpoint generator. Start by selecting the country. Add a state or city when you are checking something local, such as a delivery area or a city-specific search page. A national catalogue check can often use country targeting. Keep the selected location with the generated endpoint so a colleague can tell which market that connection is intended to check.
After connecting, check the exit IP's reported location and open the target website. Look at the website's own location settings too. A saved delivery postcode, account address or language preference may take priority over the IP. For a local delivery test, set the postcode deliberately and keep it the same on repeat visits. If the result looks wrong, try a clean browser profile and compare the requested location with the site's displayed country. IP lookup databases can disagree, so include the lookup service and the actual page result when contacting support. Static ISP and datacenter location choices depend on current stock; their order form shows which country and city allocations are available.
Select the country first, then add a state or city when the page you are checking needs it.
Which pages should you test before a larger order?
Choose a short list of pages that reflects your project. For a shopping-site check, include a category page, a product with several variants and a product that is unavailable. For a localized website, include the homepage and a page where language or delivery options change. If you need several countries, run the same checks in each one. These examples show whether the setup handles the parts of the site your project actually uses.
Write down the fields you expect before running the test. Open a few results manually and compare them with the values saved by the script. Look for missing prices, unexpected currencies, duplicate products and pages that show a login prompt. Repeat a small part of the test after changing just one setting, such as the requested city or session type, so you can see its effect. Save the working endpoint configuration with the password removed. Also try a deliberately unavailable page to check that your application records the error and moves on. Once the sample works, use its traffic consumption and completion time to estimate the size and schedule of the full run.
Include the kinds of pages your application will visit, including one that shows how it handles an error.
When should the proxy IP rotate?
Choose rotating residential connections for checks that can finish independently, such as reading separate public product pages. Generate a rotating endpoint in the dashboard and use it in the application making those requests. Each result should include the page address and the time it was fetched, so you can find the original page if something looks wrong. Check how your client reuses network connections when you need a fresh exit for a new request.
A login, shopping basket or multi-page form usually needs more continuity. Choose a sticky session for those steps and keep the same browser profile until the task is finished. Switching the IP during a login can cause another verification prompt or interrupt the session. When a request fails, read the error before changing the IP. Incorrect credentials need correcting, and a broken page selector needs updating. For a temporary timeout, retry a limited number of times with a delay. Keep the destination's rate limits in place across all connections. Rotating addresses should be part of a planned request schedule, with unfinished URLs saved so you can retry them without downloading the whole list again.
Use rotating connections for separate requests and keep related steps in one session.
How long can you keep a residential session?
Fusion Proxy's standard residential product offers sticky sessions from 1 to 120 minutes. In the endpoint generator, choose Sticky, set the duration and copy the generated connection details into your application. Use those details throughout the visit. This suits a series of connected actions, such as signing in to an account you manage, opening several account pages and checking a setting. Keep the browser's cookies and storage in the same profile during the session.
Choose a duration that leaves time for the whole visit, including typing and normal pauses. For example, if your own test normally takes around ten minutes, allow some extra time for a slow page or a verification step. Check the public IP at the beginning and end when troubleshooting an unexpected change. Household connections can become unavailable, so save progress before any step that is difficult to repeat. If a connection is lost during a form submission, check whether the submission succeeded before sending it again. When you need an address to remain assigned across several days, use the static ISP or datacenter options rather than extending a short residential visit.
Set a sticky duration from 1 to 120 minutes and use the same session for each connected step.
How much proxy traffic will your project use?
The amount of traffic depends on what your application downloads. A browser may load the page, images, fonts, scripts and background requests. A script that only retrieves the HTML can use much less. To estimate your standard residential plan, run a small batch with the same client and settings you intend to use later, then check the change in traffic usage in your dashboard.
As a calculation example, if 100 completed page checks use 20 MB, 10,000 similar checks would use about 2,000 MB, or 2 GB. This is an example of the arithmetic; measure your own pages because a photo-heavy page and a short text page can differ considerably. Include repeat visits and retries in the estimate. If you only need text, check whether your browser tool can skip unnecessary images or video, then confirm that the required text still loads. Keep images enabled for visual checks such as banner or layout reviews. Review traffic again after a website redesign or a change in your script, since either can alter how much gets downloaded on every visit.
Test a small batch, check its traffic use in the dashboard, then scale the estimate to your planned run.
What should you check when a proxy request fails?
Check the error returned by your client before starting another request. A proxy authentication error usually points to the credentials or the way they were entered. A timeout can involve the proxy connection, the destination or your own network. If a website loads but the expected price or heading is missing, inspect the page content and the selector used by your script. Keeping these errors separate makes the next step much clearer.
For a temporary connection failure, use a small retry limit and a delay between attempts. Save the failed URL so it can be retried later without running the whole list again. If the destination returns a rate limit, follow its retry instructions and reduce the request rate. Stop and review access when the site rejects the requested operation. Be especially careful with forms, orders and account changes: a timeout after submission can occur even though the change succeeded. Check the account before submitting the same action again. When contacting support, include the time, client, protocol and response message, with the password removed. A single request that reproduces the problem is more useful than a log full of repeated failures.
Read the response first: a timeout, incorrect password and blocked page each need a different fix.
Before and after: save a setup you can use again
Before saving a setup, a team may paste a proxy into a browser, open a page and leave the settings in that one window. The next person then has to find the endpoint, choose a location and repeat the checks. A saved setup is easier to use again: give the profile a clear name, keep the credentials in protected settings and record the country, session type and test page beside it.
For example, a shop team checking its German catalogue could save a German residential endpoint, a browser profile with German language settings and a delivery postcode used for the test. Keep a product URL and the fields to check, such as price, currency and stock status. On the next visit, open that profile and repeat the same check before starting the full product list. If a result differs, you can inspect the saved settings and the page instead of guessing which connection was used. Update the notes when the shop changes its page layout or the team changes its test location. This also gives a colleague enough information to continue while the original operator is away.
Save the settings with a tested page so your next run starts from a configuration you already know.
How can you tell whether a scheduled job is still working?
For a scheduled collection job, keep a short summary of each run: pages attempted, pages completed, errors and the fields that were missing. A price-monitoring script should tell you when it saved a product without a price or currency. A localized website check should report an unexpected country or language. These checks catch problems such as a changed page layout that can leave the network connection working while the saved data becomes incomplete.
Keep the application version and selected location with the run summary. When a result changes, compare it with a recent run using the same page list and settings. If the new run includes many more pages, allow for that difference before treating a longer completion time as a problem. Choose alerts that tell someone what to do next: update expired credentials, inspect a changed product page or pause a queue that is repeatedly receiving rate limits. Keep a few redacted error examples to help with diagnosis. Review the dashboard's traffic usage alongside the completed page count, especially after changing retries or adding browser resources. A sudden increase can reveal repeated downloads that deserve attention.
Watch for missing fields and unexpected pages as well as connection errors.
Which proxy type should you choose?
Residential proxies provide household IPs with rotating connections or sticky sessions. Fusion Proxy's standard residential product supports country, state and city targeting and is billed by traffic used. Static ISP proxies provide assigned ISP-registered addresses, while datacenter proxies provide assigned server-network addresses. For both static products, check the countries and any city options currently offered in the order form.
Start with the requirement that would be hardest to change. For an IP allowlist, that is usually the fixed address. For a regional website test, it may be the country or city. For a large collection job, traffic usage and the site's response to the chosen IP type matter. Test a small set of actual target pages with the options that meet those requirements. Check the content returned, session behavior and cost for the expected run. Compare current plan duration and stock before ordering. If you need steady high-volume residential traffic with country targeting, also look at the unlimited speed-tier plans. Keep product differences visible in the comparison so you can see which setup the monthly price would actually provide.
Choose rotating residential access for changing household IPs, or a static allocation when the IP needs to stay assigned.
Need help choosing or connecting?
Check current plans and available locations before ordering. For setup help, use the connection documentation or tell support which application and website you want to connect. Include any error message and the selected protocol, with the password removed.
