I hope this guide will help for people who searching for guest post service. I dont your waste your time by writing unwanted things like introduction. So lets go to main things. The following question will arise when you select the sites from list. 1. what are the niche sites should we choose? 2. what would be the PR,DA,PA,CF and TF? Ans: 1. You can choose exact related to your niche or some partially related niche or general niche that should be expressed something about your niche. 2. The following values enough to take link Page Rank = 0 to any( PR is not a matter now) Domain Authority = 15+ Page Authority = 15+ Citation Flow = 15+ Trust Flow = 15+ Page Authority should be higher than Domain Authority. Ex : DA: 30, PA: 40 Ex : If you have fresh travel niche site and want to make ranking on search engine you ask the seller below I need travel related guest post sites with PR0 to 5, DA15+, PA15+, CF20+ and TF20+. If you don't have sites with these requirements,don't waste your money and better choose the any other latest link building methods. Good Luck.
