GSA Search Engine Ranker is a software that allows you to automate website optimization and build a lot backlinks to dominate search engines and be on top with your keyword. Here is how you can configure it for proxy use:
Inside GSA Search Engine Ranker, click Options, and click Configure next to "Use proxies"
Copy proxies from the VIP panel and click Add Proxies > Import from Clipboard (our proxies are just in host: port format, compatible with either format listed)
Click Test Proxies > Against Anonymous Test URL first to ensure proxies are authorized and working.
Then try testing against the other options next.
If all or some proxies fail the GSA Anonymous URL Test, first please ensure your IP is authorized and test a single proxy manually in a browser.
If proxies pass for the GSA Anonymous URL Test but they fail for another test (e.g., the Google test), please export the proxies which fail and
send a message to support requesting those proxies be replaced with "Google Proxies for GSA".
