Over linking does swamp devalue if you prefer the high value links The standard linking colour blue also causes disruption when reading text that contains too many links A subjective decision does have to be made sooner than later regarding what to link or you risk reaching the point where too many links are introduced Or do you believe that readers can also make their own rational or personal choices about what to click in the previous sentence In the case being discussed it s easy for someone whilst reading about French wines to enter the word France in the search box and then to click the Go button however the France article adds little to the topics covered in an article on French wines Relevant regions yes grape varieties yes esoteric production terms yes but France no Here s a broad rule of thumb link deeper often sideways sometimes upwards hardly It s interesting that French got mentioned because the French WP contains some of the most hideously over linked articles imaginable We should avoid joining them
