I have some level 1 links that I created by hand and use GSA to create links to those pages. The ping tool in GSA would be perfect as a separate backlink checker that could run locally or on a VPS.
I can not verify them again because GSA did not make the links. I can not find any software to do this from my local machine. There are some services that will ping servers to make sure they are up and running, but not to ensure that my article is still active in WordPress or LiveJournal.
My list of URLs that GSA did not do now has more than 300, and it is difficult to verify those resources before building more links to them.
I would like the ping tool to load an .xls, .csv or a text file containing the backlinks that should be verified in order to verify each project separately to find deleted pages before spending weeks or months creating links to the web deleted pages
