Targeting search engines?

If you target a search engine like google, bing or yandex, you need a special Search Engine Results Page (SERP) proxy API. Use Bright Data SERP API to target search engines. Click here to read more about Bright Data SERP proxy API.

Correct setup of proxy test to avoid “PROXY ERROR”

In many tools you will see a “test proxy” function, which performs a conncectivity test to your proxy, and some add a geolocation test as well, to identify the location of the proxy. To correctly test your proxy you should target those search queries to: https://geo.brdtest.com/welcome.txt .

Some tools use popular search engines (like google.com) as a default test target. Bright Data will block those requests and you tool will show proxy error although your proxy is perfectly fine.

If your proxy test fails, this is probably the reason. Make sure that your test domain is not a search engine (this is done in the tool configuration, and not controlled by Bright Data).

Maintain a consistent IP throughout your browser session by using the -session parameter in your username. This is essential because BrightData proxies default to rotating IPs with each request. Learn more

New users should begin with ISP or Data Center proxies, as residential proxies are incompatible with browser integration in Immediate-Access mode .

For use-cases related to account management, use a consistent static dedicated IP for each account you are managing. dedicated ISP proxies should be used for this.

Getting “Software is Preventing Firefox From Safely Connecting to this site” Error?
