I ordered a Level 1 package on December 16th targeting one keyword phrase.
While the phrase we targeted wasn't super competitive (about 930,000 results), we moved up from an average Google ranking of 52 (over the last 14 months) to the 8th position.
Seems like a pretty big jump and pretty fast in my experience with SEO so I'll keep an eye on it, but I'm very satisfied with those results. Highly recommended.
UPDATE: Our ranking has improved to 4 as of today.
I had onthewayup do another keyword phrase and within a day or two of receiving the report my phrase went from an average Google ranking of 81 to 47. The singular version of my keyword phrase also jumped from an average of 144 to 64.
Again, not a very competitive phrase, but a big jump in rankings very quick.
Thanks onthewayup.
