Betty LaRue Posted December 3, 2014 Share Posted December 3, 2014 I'm sure this has been explained before...I just don't know where. In Alamy Measures, what is the difference between total CTR and Average CTR? Those numbers vary a lot between each other. Betty Link to comment Share on other sites More sharing options...
JohnB Posted December 3, 2014 Share Posted December 3, 2014 Last time I answered this I got it around the wrong way. total CTR = (add all zooms for all pseudos together and divide by the sum of all the views from all the pseudos ) *100 average ctr is just the average from all your pseudos Link to comment Share on other sites More sharing options...
Betty LaRue Posted December 3, 2014 Author Share Posted December 3, 2014 Thanks, John. average ctr is just the average from all your pseudos Average "what" from all your pseudos? Isn't that the same as the first? Or is it simply views not zooms? Link to comment Share on other sites More sharing options...
SFL Posted December 3, 2014 Share Posted December 3, 2014 I am just guessing. Isn't Average CTR for a certain Alamy Mesure period? Link to comment Share on other sites More sharing options...
JohnB Posted December 3, 2014 Share Posted December 3, 2014 average ctr is the average of the ctrs of each pseudo ie, add them all and divide by the number of pseudos. It's not the same as the total: eg pseudo A has 1000 views and 10 zooms ctr = (10/1000)*100=1 pseudo B has 5000 views and 5 zooms ctr=(5/5000)*100=0.1 pseudo C has 500 views and 10 zooms ctr=(10/500)*100=2 average CTR (for A,B and C) =(1+0.1+2)/3 = 1.03 total ctr (for A,B and C)= (add all zooms/ add all views)*100=((10+5+10)/(1000+5000+500)(*100 = (25/6500)*100 = 0.38 Link to comment Share on other sites More sharing options...
MariaJ Posted December 4, 2014 Share Posted December 4, 2014 Are these averages over a specific time period? Is it a year? Link to comment Share on other sites More sharing options...
Betty LaRue Posted December 4, 2014 Author Share Posted December 4, 2014 Wow, confusing. Which one is the most important figure when evaluating one's portfolio? I would think total. Link to comment Share on other sites More sharing options...
