Example i have a site with 20 or 100 pages doesnt matter I make a change to pages blue and yellow widgets How or what tool will tell me.. Currently or for the last 6 months page blue and yellow widgets gets 100 hits a day Then after my changes and reindexing i can check again and see if my hits(traffic) for blue and yellow widgets goes up or down. How do i measure or track this? Does this make sense?
Do you mean that you want to track incomming search engine traffic based on each page pre & post modification?
