I have an ecommerce site that sells rather expensive items that require installation from a professional. We don't offer the installation services, so the customer has to figure that part out themselves. In order to off-set our PPC advertising costs, we're looking at including an affiliate link to a well-known professional service finder that will help the visitor through the process.
Will this hurt our rankings or have any foreseeable negative affect on how Google views our site as a whole? The affiliate links will only be found under a specific category of products. We have 20 or so categories.
