French term (edited): inutile pour ceux dont les clients boudent Google

At this level (broadly speaking, this customer base is more likely to tend towards the general public end of the market), I'd prefer to use the word 'customer'.

I think Verginia's 'steer clear of' is also quite good for 'boudent', and looks as if it ought to fit the register OK.

Note that this sentence really needs to be considered in conjunction with the one following, in order to maintain the structure and balance of the two.

I personally think that 'no use / help' (or even 'not much...') is a more idiomatic way of expressing 'inutile' — EN loves these 2-part terms, cf. 'not much / very' to translate 'peu', where in EN we would less often say 'little', except in fairly limited expressions like 'little-used' or 'little-known'; but for 'peu coûteux', for example, we'd more likely use something like 'not very expensive'
