We operate a site that lists service providers and serves as a lead generation platform for them, specifically via external links that point to our partners. (~90% of our pages contain 1-3 such external links, which we'll ultimately reduce to around ~15-30%.)
Ideally, instead of linking to
www.ourclient.domain directly, we'd have internal URLs like
www.ourwebsite.domain/redirect?target=www.ourclient.domain, i.e. a redirect URL that takes the target as an HTTP GET parameter.
The question is: What is best practice for implementing redirects to external sites, specifically from an SEO perspective?
So what is best practice? Has Google perhaps even given guidance on this?
