Personally i dont interlink my autoblogs, especially if you using adsense as if one goes they all will.
What i do is use LFE and build blogs which are for nothing but backlinks then interlink all those, then link to my auto blogs
Iv only been autoblogging for 2 months, and only built 10 autoblogs but my traffic is starting to increase now i have done this.
These 10 blogs have been a test and now im starting to make some money, not much but its starting i will be building a lot more. I can put up a good autoblog in no time now, very easy to set up. I used kingbrend guide when i fist started out and its by far the best and most indeth one that iv seen.
