Hi Guys, I am working on a data mining project where I search on google for something, visit the results manually and collect what I need. I need one site only once, I need to avoid listing them twice. After a few hundred pages, I am constantly finding dup links. I can't remember all the pages I've already visited, I am only human! So most of the time, I revisit a link, then do another search on my excel sheet, and confirm its a dup .. total waste of time. I am at some point when 75% of the links I am visiting is dupe, I have already visited them !! I need someway, probably a google chrome plugin, that will mark the pages in search result that already visited once, or any other method that might save me some time. You help is greatly appreciated, Thank You.
