I was wondering how bad are affiliate links for SEO.
I remember several years ago, I thought it might be a great idea to make a few extra bucks with eBay affiliate program on my ecommerce site.
Within a month or so I was heavily penalised by Google and the site hardly ever recovered.
Since then, I've never touched any affiliate programs. I am now running a travel blog and I am quite tempted with having a few Tripadvisor links through my travel post, but scared with the outcome.
So how is now Google looking at the affiliate links? Are they bad for SEO? Should these links be nofolllow?
