I have a bookmark folder in Chrome, which I open in Incognito - the bookmarks are the search results of my chosen keyword, on a chosen page of Google results. I can then open all tabs in 1 click and get the results by shifting through the pages.
Of course if the ranking position changes I may have to go through a couple of pages (hopefully up not down!) This is ok for a few keywords. For the bulk of the lot I use Traffic Travis. Seems ok. Updates them once a day which is more than enough.
The tool on this website is nice also
