Raquel, in answer to your question in regards safelists, only use the ones in the Top 10 of my rating service as below, and 'State Of The Art' is for me (in the internet affiliate marketing niche) outperforming all others by a wide margin. It's well worth considering taking up a paid membership.
SOTAM well and truly beating all others at 8.2%
