How to check verified links ?

I have scraped around lots of links from gscraper. I want to run this on GSA SER. Can SER able to check which links are verified without registering and submitting data.

What do you mean by verified? Do you mean URLS that already have your link on them? If so, it's probably easier to use a free tool like this: http://www.scrapebox.com/free-link-checker

If you mean identified URLS, you can import that list into the identify and sort in and it will sort the links it's capable of posting to.
