I sometimes wonder if a rival site is somehow sabotaging my position in Google search results. I am sure this is just paranoia, but Google's webmaster tips are not entirely reassuring. They say there is 'almost nothing' a rival can do to damage your rankings. I don’t like that 'almost'. It implies there IS something a rival can do. Does anyone know what the 'something' implied by 'almost nothing' might be? Is everyone confident that a rival can’t do anything in this respect?
