It might be early days for an observation like this (for me anyway); I started uploading to IS early in February and make what I thought was good progress. I didn't bother with any other agencies except a few uploads to DT. Sales at IS improved very micely and by the middle of March I was pleased with overall progress. Then I decided to join SS. Sales at SS took off sharply and I was mesmerised by the immediate positive result.
However my sales at IS peaked in exactly the same week that I joined SS. Over the past four weeks the trend at IS has been down, but still very positive sales at SS.
Of course Easter is in the middle, perhaps wiping two weeks of proper statistics, but I jave a sneaking suspicion that somehow my sales at SS have damaged my progress at IS.
Perhaps I'm wrong and its all just coincidence.
Anyone else have any thoughts on this from their own experiences?
