I have a website that just recieved an email from a company claiming to have an interested party in advertising on the site. Apparently they are interested in purchasing a certain amount of space on the site for a product write up that would remain on the site for a year and possibly have the option of renewal.
At the moment the only advertising I've allowed on the site is adsense, but of course if the price is right I would consider it.
I am very wary of the outlook sponsored advertising has on the site and I'm keen to keep the website as independant as possible within means.
Really I just dont know where to start with negotiations, how much can a site charge per unique visitor? and what strengths should I look to highlight on the negotiation table?
