Website Advertising

[raindog]

Hi,

I originally set out to just build a simple site for my partner to promote her small business ...the site grew as it became obvious that a site wasn't any good unless people could find it. It now ranks reasonably for the key words/phrases I am interested in. There is no 3rd party advertising on the site

I have been approached by a party who want a home page link to their site plus they want to plant 3 "relevent" articles in my site. They say they will pay £75 ($120) a month to do this.

What are the cons? Would they leech much ranking from the site (i.e. would I drop down in Google), would customers find it annoying? Does it devalue a site? Are there any scams to be aware of?

Are there any key questions to ask? Demands to make? (Minimum term contract?)

This is all new to me so any advice appreciated.

Thanks in advance
