Just a quick question... Why does the Keyword tracker check backlinks before it checks keywords? Keywords can change hour by hour, but backlinks only seem to change when Google does an update. Any thoughts on reversing the order of operation so you don't have to wait for backlinks to be checked to see your keyword rankings? Maybe reduce some load on your server by adding a "skip backlinks" checkbox?
Because typically there are less back links being tracked (and individually they are also faster than keyword checking).
