It’s imperative to mask or cloak your naked affiliate link if you do not want to lose commissions for nothing.
Why to cloak affiliate links?
- Most often look quite ugly -> Cloak for more nice looking link
- Google may penalize you for having affiliate links on your page. For normal ranking in google search results, this means a lower position in the SERPs (search engine result pages). If you use adwords, this equates to a lower quality score which in turn makes your cost per click more expensive.
- Naked affiliate link lead commission hijacking (specially if promoting to other marketers) -> Potential buyers can simply switch your affiliate id to their own and get a discount from their purchase of the clickbank product you’re promoting.
