I been with twitter for 8 month for normal bookmarking, i never follow other's nor following me (sorry i don't understand how it work)...... Recently (two day ago),follower number gain for no reason .... So i would like to ask, what the purpose of following other ? what effect of twitter in SEO ? Serp ? they follow me, direct message me but none of them visit my site (from analytics)... Real surprise me, from 2 follower to 67 in two day and increasing ...
