OK here's my SERP change review as promised -
First I have to tell you guys that this guy is extremely punctual when it comes to the delivery, he delivers the report almost same time everyday, really awesome
Now regarding SERP change -
I given total 10 keywords, and seen the following result just a while ago
SERP Improved
Keyword 1 - search result - 38,000,000 - before 7, now 6 (this is my primary keyword and it's a 2 words keyword, not long tail, and I got stuck in 7th for last few months. I tried several link packages from this forum, at least, this one able to move it
- yes it's just 1 step forward, but I have tried several high priced packages and none worked - so, I'm really happy
)
Keyword 4 - search result 419,000 - before 5, now 4 (long tail keyword)
keyword 5 - search result 236,000 - before 6, now 5 (long tail)
Keyword 8 - search result 394,000 - before 10, now 7 (long tail)
keyword 9 - search result 2,560,000 - before 6, now 2 results in 5 and 6 - I'm quite surprised with this one, now I have 2 result in top 10
(long tail)
SERP Degraded 
keyword 6 - search result 4,150,000 - before 25, now 31 (3 words keyword, long tail)
Rest are remains same.
So, quite impressive result overall after just 5 days - I'm sure that I'll see lots of improvement over time with its drip feed effect
Edit: Please note: I'm using only my home-page URL with 10 anchors/keywords variations, I'm quite aggressive when it comes to linking
BTW, my site is almost 3 years old with PR -1.
