Hi future x
The products are actually mobile phone deals that are updated 1-2 weekly by the merchant. Each handset has about 50 variations on the deal that is being offered, these are different monthly minutes, variations in message packages and also internet coverage.. As for removal I would do this, upload each batch of 10,000 products under a set category [ I am using wordpress], then when I am finished with them remove that particualr directory via webmaster tools...
If I were trying to sell computers etc each product would probabaly have a longer life span, the difficult thing is mobile deals change very frequently..
I quite often come across affiliate pages that are months out of date, maybe I am striving too much for perfection?
Maybe on reflection I carry out some sort of monthly staggered rotations..
Many thanks for your reply..
