I can find your audience elsewhere

The internet is not TV, or radio, or print. Lots of people may only watch one or two shows. Lots of people may only listen to one radio station, or only read one newspaper.

Nobody only goes to one website. Your site is not irreplaceable.

I can always find your audience elsewhere.

If you really, really value your website, and see it as a necessary site on my media buy, then you should be trying your hardest to convince me of that. If you see it as so important, so necessary, so irreplaceable that you won't bargain, won't facilitate, won't help, then you're off. I'll find your users somewhere else.

I always can.
